Who doesn’t love soaking in a warm bubble bath? It’s one of my favorite ways to relax after a long, stressful day. In the quest for the perfect bubble bath, I spent more than a year developing a great solid bubble bath recipe. I was inspired by so many great recipes and tutorials, and this video by Good Earth Spa in particular was incredibly helpful. These LoveSpell Bubble Bars are made with that very recipe, which is a combination of glycerin, castor oil and an array of dry ingredients. When combined they create a dough-like texture that you can roll and cut. The bars harden in about a week, and can be crumbled into your bath tub.
These LoveSpell Bubble Bars are super girly and fun. I used Eastern Purple and Pinkberry Sherbert LabColor for a wonderfully feminine color scheme. LoveSpell (Type) Fragrance Oil features notes of apple blossom, white musk and Italian bergamot. It smells wonderful. A heavy sprinkle of Lavender Mica and Fine Iridescent Glitter brings the wow factor. They would make wonderful Valentine’s Day gifts!
If you have never made solid bubble bath before, I would highly recommend watching the Soap Queen TV video below. They are a little bit tricky. The dough is rather sticky and does take a gentle hand to roll evenly without tearing. If you have ever rolled sushi or a jelly roll cake, that experience will come in handy for this project! In the video below, I use a different color scheme and fragrance for a totally different feel. Feel free to add your choice of LabColor and skin-safe fragrance oil to create your own custom project. I don’t recommend making substitutions for the dry and wet ingredients in this recipe. It took a very long time to formulate, and replacing ingredients can greatly affect the texture of the dough or the bubbles.
What You’ll Need:
7 oz Liquid Glycerin
1.8 oz Castor Oil
0.7 oz Lovespell Type Fragrance Oil
10.1 oz Baking Soda
7.4 oz Cream of Tartar
2.7 oz Corn Starch
0.6 oz Modified Tapioca Powder
5.8 oz SLSA (Sodium Lauryl Sulfoacetate)
12 mL Diluted Eastern Purple High pH LabColor
6 mL Diluted Pinkberry Sherbert LabColor
Fine Iridescent Glitter
Lavender Mica

DILUTING LABCOLOR: You’ll need to premix your LabColors in order to use them in this project. We like diluting the small bottle of LabColor in 4 oz. of distilled water. For more on diluting LabColors, check out this blog post.
ONE: In a small container, mix together the liquid glycerin, castor oil, and LoveSpell Fragrance Oil. Stir until all the wet ingredients are completely combined.
TWO: In a separate container, add the dry ingredients (baking soda, cream of tartar, corn starch, tapioca powder and SLSA) one by one through a fine mesh sifter and into a large bowl. The sifter ensures the mixture is completely smooth and clump free. I recommend adding the SLSA very last. SLSA is extremely fine and powdery, and can become airborne very easily. You may want to wear a mask during this step to avoid breathing in any SLSA. Once all the ingredients have been added, slowly mix together the dry ingredients.
THREE: Pour the wet ingredients into the dry, and slowly work the ingredients together. A spatula or your hands is the best way to work in the wet ingredients.
FOUR: Once the dough is thoroughly mixed, divide it in half. To one half, add 12 mL Eastern Purple LabColor and use your gloved hands or spatula to thoroughly mix in.
FIVE: To the other half, add 6 mL of the Pinkberry Sherbert diluted LabColor and use your gloved hands or spatula to thoroughly mix in the colorant.
SIX: Prepare your tabletop. Place a large piece of freezer or parchment paper on your work space. Then, lightly cover the paper with a dusting of baking soda. You don’t need a lot, just enough to keep the mixture from sticking to the paper. Then, take the purple “dough” and form a long log shape. Use your hands to flatten and spread the mixture.
SEVEN: Place the pink dough on the top of the purple, and spread it out until it almost completely covers the purple. It’s okay if there is a little purple still sticking out!
TIP: If you’d like the layers to be super smooth, cover the top with another piece of freezer or parchment paper, and use a rolling pin (or other round tool, like a Heavy Duty Column Mold!) to gently roll out and smooth the layers.
EIGHT: Now it’s time to roll! Starting on the side closest to you, begin to roll the dough up. With every roll, gently peel the paper back, then continue rolling. For this step, I would recommend checking out the Bubble Bath video on Soap Queen TV to get a better idea of this process.
NINE: Once the dough is completely rolled up, use your hands to gently press the layers together and compact the roll. You can also transfer the roll to a clean piece of parchment paper, and roll again as you shape it.
TEN: Sprinkle the top of the roll with Lavender Mica and Fine Iridescent Glitter.
ELEVEN: Use a sharp knife to carefully cut the roll into bars. Transfer the bars to a clean piece of parchment paper and sprinkle with more glitter. Be very careful when handling the bars, as they will be very soft and very delicate.
Allow the bars to lay out for at least 3 days to harden. Depending on your climate, they may need over a week to fully harden. To use, crumble the bars and place them into the tub while the water is running to create the fluffiest bubbles. Enjoy!
Have you made bubble bars before? They are a little bit tricky, and definitely take some practice. But they make such wonderful gifts, and are so fun to use! If you have any bubble bar tips or tricks, I would love to hear them!

Janine says
Is tapioca powder the same as tapioca flour?
Kelsey with Bramble Berry says
The main difference is the tapioca powder has silicone to give it a silky feeling. Tapioca flour will work in this recipe.
Crystal says
Hello thanks for the great video! I had a couple questions. Is liquid glycerin simply liquid soap? And is SLSA something that I could buy at the grocery store, Or do I have to order online?
Kelsey with Bramble Berry says
Liquid glycerin and soap are not the same. Glycerin is a vegetable-derived liquid that helps draw moisture to the skin. It is a natural byproduct of natural soap, but for this recipe we recommend glycerin.
Liquid glycerin: https://www.brambleberry.com/Glycerin-Liquid-P5965.aspx
Also, I’m not sure if you can find SLSA in stores, but we sell it on BrambleBerry.com: https://www.brambleberry.com/Sodium-Lauryl-Sulfoacetate-SLSA-P5244.aspx
Jo says
Hi,
Can I remix a batch of bubble bars that have started to dry? They have been sitting for a few days. I decided I don’t like the color and want to mix them up again to add more white. Will they still work?
Kelsey with Bramble Berry says
I’m not entirely sure. Once the bars dry out they may be hard to work with. You may want to try a tester bar to see if it can be remixed.
Sarah says
Hello i habe start my own bath n body products line just at home. So i habe been slowly wprling my way though the recipes on here. And i love pretty much all of them. I wpuld like to try this bubbles bars but I could only find quick cooking tapioca. Sounds like its sand inside the box. Would this work aswell?or is there lile a base recipe for bubble bars. Linda like bath bombs how they always start with 2 parts baking soda 1 critic acid!!! Also don’t know how I’m going to find this post again after I post this hahah thanks.
Kelsey says
As long as the tapioca is just tapioca starch and doesn’t have any additives it should work well. If it has thickeners or anti-clumping additives it may do weird things in this recipe. The ingredient list should say what’s in the powder.
-Kelsey with Bramble Berry
Katherinne says
Can I use SLS instead of SLSA? If so, how would the process be? I can’t find SLSA in my country.
Kelsey says
Yes, that will work just fine. You can add it the same way and in the same amount as the SLSA.

Debbie says
I’m unable to locate the modified tapioca powder called for in the recipe on the Bramble Berry website. Is there an alternative option, such as arrowroot powder?
Kelsey says
We haven’t tried this recipe with arrowroot powder, so I’m not entirely sure. They do have similar properties, so I would recommend making a small test batch to see if it works in this recipe. You can also find tapioca powder (or flour) online or in grocery stores. I’ve found it in the baking or bulk aisle.
-Kelsey with Bramble Berry
Arrowroot powder: https://www.brambleberry.com/Arrowroot-Powder-P3706.aspx
Debbie says
Thank you!
Stephani says
I made these bubble bars exactly as the directions said. But they turned out so soft, like won’t hold their shape soft even after allowing them to sit for a few days. What went wrong?? I’m so sad : (
Kelsey says
How many days have they been sitting? These can take at least 3-5 days to harden, longer in humid climates. Also, where are you storing the bars? I can help you troubleshoot. 🙂
-Kelsey with Bramble Berry
Stephani says
It’s been 7 days and they are in my craft room on the second floor of our house. I have even tried putting a fan near them. I was thinking about it lat night and I think it may be because I used fragrance from the craft store. Could using a cheap fragrance be the cause?? Thank you for the help!
Stephani says
Like I have made these before with other fragrance bought from soaping websites and they turned out just right that’s why I think it’s the craft store fragrance. But I only used half an ounce.
Kelsey says
The fragrance may affect it, but I’m not entirely sure, especially because it’s such a small amount. It may just be that the weather is a bit hotter and more humid than usual. You may find in the summer they take longer to dry. For your next batch, you can reduce the liquid slightly to help them dry more quickly.
For the batch now, the oven can help dry them out. Preheat the oven to 200F, then turn it off. Place the bars in the turned off oven for 15 minutes. That can speed up the process a bit.
-Kelsey with Bramble Berry
Lynne says
These look beautiful and I can’t wait to try them! Can this recipe be used to form “ice cream” bubble scoops as well?
Kelsey says
I believe that would work just fine. When they’re first made they have a nice soft texture that should make really cute ice cream scoops. I would recommend sprinkling the scoop with a bit of baking soda to prevent the bubble bath from sticking to it.
-Kelsey with Bramble Berry
Stephani says
Yup! I have done it. I made chocolate ones and they looked just like ice cream scoops. They were a big hit with my customers.
jennifer says
hello I was wondering if you could add just tapioca flour instead of corn starch? I have heard the corn starch in bath products could cause yeast infections in women….
Kelsey says
This recipe is safe to use in the tub! You may want to talk with your doctor just to be sure. 🙂
If you don’t feel comfortable using the cornstarch, you may want to try another recipe. This one we don’t recommend any substitutions. You may like regular bath bombs, which don’t contain cornstarch! Find recipes here: https://www.soapqueen.com/category/bath-and-body-tutorials/bath-fizzies/
-Kelsey with Bramble Berry
Stephani says
What about arrowroot flour? I know of a lot of people that swap the arrowroot for corn starch in other bath product recipes.
Kelsey says
We haven’t tried this recipe with arrowroot powder, so I’m not entirely sure. You can make a small test batch to see how it works if you like. Keep in mind we don’t recommend substitutions, as they can change the consistency and performance of the bars.

Nahla says
Please can i use SLS liquid because i cant find it powder
Kelsey says
We haven’t tried SLS liquid with this recipe, so I’m not entirely sure how to incorporate it. The SLS is diluted with water, so you will need to figure out how much it’s diluted so you can add 5.8 oz. of SLS (plus the extra water). The water will also make the dough more wet, so you’ll need to add less glycerin and castor oil. You may want to make a small test batch to see how to adjust the recipe. 🙂
-Kelsey with Bramble Berry
Nahla says
Ok i will try and tell you
Thanks alot😍
Theresa Christine says
Yikes! After 4 weeks and counting my are still not dry. Unfortunately that is not the worst part…around the middle of week 4 they started turning a different color! I made 3 batches on the same day and they are all discolored! The darker color (love spell combo) started turning to a grey putty color and the other one with teal and white combo looks dirty. When I break them apart the color on the inside is still vibrant and beautiful!
It has not been very humid here (San Diego, CA) and I even waited to make these until the forecast was going to be clear for the foreseeable future.
Please Help! What happened? I am discouraged about how long it is taking for these to dry but now they look absolutely disgusting!
Kelsey says
I’m sorry about that Theresa. Did you use LoveSpell fragrance, or another one with vanilla? Fragrances that contain vanilla can discolor over time. Also, I’m not sure why it didn’t harden! Where did you store the bars to dry? Let me know and I’ll help you troubleshoot. 🙂
-Kelsey with Bramble Berry
Sherry Bradford (aka Merry Sherry) says
I live in the Dallas, Texas area and the amount of glycerin in this recipe seemed pretty high for our area. Here’s the difficult part though – if you use too little, these are going to crack and if you use too much it can take longer than a week for them to firm up. Mine took two weeks with a fan running across them the entire time. That said, they turned out great and bubbled very nicely. What I did different next round was use 3/4 the amount of glycerin listed. I then mixed, mixed, mixed. Took a small amount out and rolled it. If it was STICKING a LOT to my parchment paper, I threw that back in and add a SMIDGE of cornstarch to the mix. By that I mean about 1/4 tsp only. Mix everything and roll out another little ball. If still too sticky, another smidge. If the opposite occurs (it didn’t for me) I would have added a drop or two more glycerin, mix and try again. It sounds like a lot of trouble, but you will find that “sweet spot” pretty quickly where it rolls without being absolutely gummy or dry and cracked. Then proceed with the rest. I then put a fan on mine and they firmed up much faster (still several days – but not two weeks!!! If I were going to add these regularly and in bulk to a product line, I would definitely want to invest in some type of dehumidifier “box” (there are several DIY options online). But for an occasional treat for myself and friends, or just a little “something extra” from time-to-time to offer Customers, they are really awesome.
Kelsey says
That’s a great tip Sherry! The humidity in your area can definitely affect how long these bars take to dry. Adjusting the liquid and dry ingredients slightly can help you get the perfect consistency for your area. 🙂
-Kelsey with Bramble Berry
Carrie says
I misread and used way too much glycerin. They are extremely wet. I made them yesterday. I did manage to get some firm but ugh. Can I add more baking powder to them?
Kelsey says
I think it would be worth a try! You can put the bubble bath back into a bowl, add more baking soda and start mixing until the dough feels more dry. I would recommend 1 ounce increments. Then, reform them and let them dry for 3-5 days until they harden. 🙂
-Kelsey with Bramble Berry
Nikki says
I love this recipe soooo much. I make my bars the same but I make little roses and layer the top then cut the loaf into triangles (cake slice) soooo wish I could show a pic. They came out beautiful!

Jazz says
Wow, those look beautifulllll; I’m definitely going to make them. Alas, it will only be next month when I order my lab colours and micas as I’ve had to put myself on a budget. Do you know how difficult that is! You are very patient answering all those same questions repeatedly. You make everything look so easy and inspired me to take my cp soap making to the next level: From red palm oil coloured soap to Dragon’s Blood with a swirl. Keep up the good work and thank you for all the recipes and tutorials.
Kelsey says
Thanks so much for your sweet comment Jazz, it means a lot to us! Enjoy making your swirled soap and eventually solid bubble bath. It’s a lot of fun. 🙂

Michelle Dixon says
Hi Kelsey, I would like to know what’s better SLSA or Coco Betaine for the foaming agent. I am fairly new to making bubble bars. I have made two batches using SLSA but find that Coco Betaine is less expensive. I have read that people may have allergies to the Coco Betaine so I want to make an informed decision about buying. I give them to the grand children. Thanks for any help.
Kelsey says
We haven’t give coco betaine a try, so I’m not entirely sure! I would recommend making a test batch with it to see what you think. If it’s not working out so well, you can use SLSA. In our tests the SLSA works perfectly for this recipe. 🙂
-Kelsey with Bramble Berry
Katrina says
Loving all your tutorials! I made these for the first time and have been sitting for over a week and still are not hard. I’m pretty sure I followed all the instructions, but I did leave out the glitter and lavender mica. I couldn’t find tapioca powder so I used tapioca flower instead. Do they just need to sit out longer? Thanks
Kelsey says
If you live in a pretty humid area, they may need to dry a bit longer! To speed that process up, you can run a fan over the bars or use a dehumidifier. If they’re still fairly wet after another 3 days ago, you can try popping them in the oven! Preheat the oven to 200F, then turn it off. Place the bars in the turned off oven for 15 minutes. That should help them dry!
-Kelsey with Bramble Berry
Brooke says
Hello, I can’t wait to try these with my daughters, but I’m a bit confused about the preservative for the lab colors. I ordered the kit for these… but I can’t make them unless I have the preservative? If so, it’s a little disappointing because I thought everything was already included in the kit. Seeing as how this is my first ever kit, I don’t have it… maybe once I get more seasoned, I’ll have it on hand all the time 🙂
Thanks in advance!
Kelsey says
The LabColors do need a preservative. Sorry about the confusion. The preservative will help protect against mold and bacteria in the color, so they’re important to have.

Lori says
I made these bars and they looked beautiful and perfect. But when I checked on them 3 days later they had turned brown! What happened?

It sounds like fragrance discoloration. Did you use a scent with vanilla? If so, it can turn the bars brown. Let me know. 🙂

Kyky says
I made this recipe to the T but after a few weeks my bubble bars are still soft. I put them in the oven and they hardened up slightly but the don’t crumble well and don’t give any bubbles at all and have a chemical smell to them 🙁
I live in a very wet and humid area but have stored them in an airtight container.
Help please!!!
Kelsey says
I’m sorry about that! How long did you place them in the oven? Also, where are you storing them? In really humid climates, the solid bubble bath can stay wet longer. Let me know!
-Kelsey with Bramble Berry
Kyky says
I left it there for maybe an hour and it became like a sloppy consistency 😮
They did slightly harden up once I took them out of the oven but don’t produce any bubbles and smell terrible, they don’t smell like the essential oils I used at all
Kyky says
And I store them in an airtight jar. Should I put them in the air right jar straight after making them?
Kelsey says
Did you have the oven on when you put the bars in? Also, we recommend storing them in the open for about a week. That helps the excess moisture evaporate and hardens the bars. In an airtight container that moisture will get trapped and the bars will stay soft. If you live in a humid climate, you can use a dehumidifier as you’re drying the bars, or place silica packets nearby to absorb moisture. 🙂

Zsuzsanna says
Hi Kelsey,
I would like to make this recipe for my kids and was wondering if i could give some goat milk powder or colloidal oatmeal to it for some extra skin care 🙂

Hey Zsuzsanna! We don’t recommend using additional ingredients in this recipe. We tested it for about a year with different combinations and found this works best. 🙂

Kayla says
I was planning on making this recipe but I do have a lot of friends asking if it is safe for small kids between the ages 1-5.
Kelsey says
This recipe is skin safe for all ages! However, if the children have any sensitivity to fragrance, you may want to leave that out. While it’s skin safe, everyone’s skin is different. Some people may find the fragrance irritating or too strong. If that’s the case you can skip it. 🙂

What is the shelf life of these?
Kelsey says
These bars should last about a year! Once they’re dry, we recommend wrapping them tightly and storing them in a cool, dry place. That will ensure they stay fresher longer. 🙂

Michelle says
I like to make a lot of my own powders from fresh products that I dehydrated and used coffee grinder to make into powder or even some dry herbs. I also use rolled oats to make oat powder and was wondering if I can use tapioca pearls that is used to make tapioca pudding to make the tapioca powder and I have some powder from dehydrated purple yams that’s a beautiful lavender color and beets for pink/red color. Even turmeric for Orange ect. Can these be used in this recipe? What about in soaps or lotions? Don’t want to waste if you don’t think it would work. Oh one more thing, have you used Suttocide A as a preservative before? Thanks!
Kelsey says
Certain powders work well in soap (like tumeric) while others don’t as much. For instance, raspberry or beet powder tends to fade to gray in soap.
I would recommend making small test batches of lotion and soap to see how the colors work! That way you can see if the colors fade or morph at all. We have some more information about testing natural colorants here: https://www.soapqueen.com/bath-and-body-tutorials/tips-and-tricks/natural-colorant-testing-inspiration/
This post has more information on natural colors: https://www.soapqueen.com/bramble-berry-news/sunday-night-spotlight-natural-colorants/
Also, I don’t believe we’ve used Suttocide A as a preservative. We typically use Optiphen, Germaben II or Phenonip. Read more about using those preservatives here: http://www.soapqueen.com/bath-and-body-tutorials/lotion/talk-it-out-tuesday-preservatives/

Deb says
I can make Alfredo Roll Ups without a problem but rolling these made me crazy lol. But they came out fine and were amazing. I plan on making more and I’ve seen recipes from reputable sources that use food coloring which I’d like to use because I don’t have any lab colors. Last time I used micas. What’s the issue with food coloring again?
Kelsey says
Oh that’s awesome, I’m glad your solid bubble bath turned out well! Sounds like the alfredo roll up training came in handy. 😉
Food coloring isn’t specifically made for bubble bath, so it can morph, fade or bleed in the recipe. We recommend LabColors or micas. They both work well!
-Kelsey with Bramble Berry
Judy says
I’ve loved reading all these comments. It’s recommended to use Poly 80 with the Micas when making bath bombs to keep the colors from streaking in bathtub. Why is the Poly 80 not used when making the Bath Bars? Thank you.
Judy says
I’ve made the Bath Bombs and just gave them as gifts. Some I used food coloring and some I used the Micas and they left a ring. I’ve never made the Bath Bars, but am planning on making. We’ve had a good bit of rain in my state. Thank you.
Kelsey says
We have found that there is little to no transfer when using LabColors in this recipe! Especially when you’re using a smaller amount. If you want to use micas you can use Polysorbate 80. We haven’t tried that in this recipe, so I would recommend a small test batch! You can add that to the liquids. I would recommend about 1-2% to start. 🙂

LaShonda says
Hi there,
I am wondering if I can substitute the castor oil for coconut oil or olive oil maybe?
Kelsey says
We don’t recommend any substitutions for this recipe! The castor oil has a thick, sticky consistency that helps hold the bars together. We tested a lot of oil combinations and found castor oil works best. 🙂
-Kelsey with Bramble Berry
Caroline says
Hi!
I was wondering if using gel food color will be ok? I have all ingredients just not the “lab colors” and really want to make this ASAP !
Thanks,
Kelsey says
We don’t recommend using food coloring for this recipe. Because they’re not intended for use in soap, they can morph, fade or bleed in the bubble bath. LabColors work best! You can also add mica to the dry powders to color your bubble bath. I would recommend starting with about 1/4-1/2 teaspoon in this recipe. If you want it a bit darker, you can add more from there. 🙂

The Soaping Owl says
I made these a week ago, and just tested a half a bar today. It was fabulous! Love it!! Bubbles galore! Only Hingis I did different were:
Colors
Tapioca Flour instead of powder (didn’t have that on hand)
Reduced glycerine
Thanks for the wonderful recipe!
Kelsey says
Yay, glad they turned out well! They’re so fun to toss in the tub. 🙂

Patty says
Hi. I was wondering if I could use liquid soap dye for colorant. I have used food coloring to make a bubble bar it was a cotton candy fragrance oil. I am new to this and am worried about them changing colors if my oils have vanillin in them.
Kelsey says
Hi Patty!
Vanilla discoloration can sometimes happen in these bubble bars, even with a different colorant. It is a bit inconsistent in this recipe – sometimes it happens, sometimes it happens after awhile, sometimes it doesn’t. To be on the extra safe side, I would recommend using colorants that don’t discolor. That way the colors in your bar will stay true. 🙂

Kathy says
I made these 5 days ago and they are still a tiny bit moist, but I tried them out anyway and was disappointed in the amount of bubbles. Not much bubbling at all and they didn’t last long either. Could it be that they need to dry out a bit more? I followed the recipe to a T and used the Bamboo Mint FO sample that I received with my last order.
Kelsey says
I’m sorry about that Kathy! In our tests we found they bubbled nicely in the tub. You can see the bubbles in action in this video: https://www.youtube.com/watch?v=oiDdK7l5dAg
When you were popping them in the tub, were they dry and did they crumble easily? Or were they still pretty soft? Let me know and I can help you out. 🙂

Kathy says
They were a bit soft after I let them dry for about 5 days. Maybe I used them to soon?
Kelsey says
I think letting them dry for a few more days will help! We have the best results when the bubble bars are nice and dry. We recommend crumbling them under the faucet to make lots of bubbles. I would recommend letting them sit another 2-3 days and trying again.
If they’re still wet after that time, preheat your oven to 200F. When it’s preheated, turn it off and pop the bubble bath in there for 15 minutes. That should help dry it out. 🙂
-Kelsey with Bramble Berry
Tara says
That is an awesome idea! This happens to me from time to time: the bubble bars stay soft for weeks. I think maybe it’s because there’s lots of humidity in the air? Do you think it would be ok if I were to put them in the oven immediately after I’ve made them? I have no patience and I always want to use them right away!
Kelsey says
I would recommend giving them a couple days at room temperature first! That will allow a good portion of the moisture to evaporate and the oven can get the last bit. If you live in a pretty humid environment, you can also decrease the liquid amounts slightly so they’ll dry more quickly. 🙂

Kristen says
Hi!
I ordered this kit because my daughters love bubble bars. However, I see that it’s necessary to add optiphen to the lab colors and that wasn’t in the kit. Is that to preserve the colors or the bars? I’m okay with one time use on my lab colors and am not that concerned with preserving them for later use. I also see that there is some optiphen already in the new formulation of the lab colors…is that enough? Will my bars get moldy or sour if I don’t use the additional optiphen in diluting my lab colors?
Kelsey says
Hi Kristen!
We recommend preserving the LabColors as soon as they’re diluted. The LabColors themselves contain Optiphen ND, but that is only to preserve them when they’re diluted. Once additional water is added, we recommend adding Optiphen ND to protect against mold and bacteria. Even with a one-time use, we recommend those preservatives to be extra careful!

Jane Schweitzer says
Instead of rolling the mixture into a loaf, can you put it in small silicone molds?
Kelsey says
Hi Jane!
We didn’t try this recipe in molds, so I’m not entirely sure! My worry is that the dough is sticky and wet when it’s fresh, so it may stick to the sides of the silicone. It may also take longer to dry, as the recipe isn’t getting any airflow in the molds. I would recommend a small test batch to see if the recipe unmolds well!
I have also seen people using an ice cream scoop to form this recipe. It’s really cute, it looks like a scoop of fresh ice cream. 🙂

Kayla says
I made a batch with the only difference is I used mica coloring. After a week my bars were still not hard they were soft and some were falling apart. IDK if they over dried or didn’t dry enough. They seemed still moist and that is why they were fragile? How hard are they suppose to be?
Kelsey says
Hi Kayla!
When these bars are first made, they will be soft and moist. They will begin to harden and dry out over the next few days. They usually need at least 3 days to dry, but can take longer if you live in a fairly humid place. Are the bubble bars soft to the touch? Do they still feel a little wet?
-Kelsey with Bramble Berry
L. Whitney says
Hi there! I’m looking to use Powdered FDA colorants in making these. Do I need to add anything during the regular colorant adding stage?
Kelsey says
Hi there!
If you’re using powder colorants, you can add those straight to the dry ingredients! Pour those into the dry ingredients and mix well, then add the wet ingredients. 🙂
We’ve had the best luck with micas in this recipe: https://www.soapqueen.com/bath-and-body-tutorials/tips-and-tricks/sunday-night-spotlight-mica-colorants/
Pigments and oxides are a bit heavier and larger in particle size, so they can cause streaking in the tub. You may want to do a small test batch to see how the colorants act!
-Kelsey with Bramble Berry
wallis lahtinen says
I asked this question earlier maybe in the wrong place. Can I use the Chrome Hydrating green as a colorant for bubble bars -think it is an oxide but doesn’t say on the jar.
Does the Butter Mint fo have vanillin in it? I would hate to have these turn brownish.
Thanks,
Wallis
Kelsey says
Hi Wallis!
Butter Mints Fragrance Oil smells so good! It does discolor tan, so it can discolor in this recipe. To be on the safe side, I would recommend using a non-discoloring fragrance: https://www.brambleberry.com/Clear-Vanilla-Free-C491.aspx
Also, oxides can be a bit tricky in the bath tub. Because they are a bit heavier, they can be a bit streaky in the tub. They can also leave marks on the tub (which can be removed with a washcloth or paper towel). For this recipe, I would recommend micas or LabColors. 🙂

Christina says
Hi! I don’t have the tapioca powder! What happens if I don’t use it? 🙂
Kelsey says
Tapioca powder helps add structure and stability to this recipe, and also gives it a slightly silky feeling. We definitely recommend using it so the bars work properly! 🙂

Kaylee says
Hi,
Thank you for sharing this lovely recipe! I live in a humid climate, so I was curious if adding the recommended amounts would make the recipe too wet. I tried the recipe as-is with the recommended weights of all ingredients, just to see. The only thing that I omitted was the colouring as I didn’t have it, so my bars are pure white. I rolled the mixture into a log and cut them into about 8 round slices – I didn’t have any problems doing so, and the bars didn’t seem overly fragile at that point. The bars have been sitting for 6 days or so, and I noticed that they are starting to get cracks in them from drying. How can I modify the recipe next time to prevent the cracks from happening? Was my recipe too wet?
Kelsey says
Hi Kaylee!
I’m wondering if the bars may be a bit dry instead of too wet! Cracking is usually a sign of dryness in this recipe. The LabColors are water based, so they do add some extra moisture to this recipe. Next time, I would recommend adding a little bit extra glycerin if you’re not adding color – about .5 oz. extra is a good place to start. That should help hydrate the bars and keep them from cracking.
The good news is the bars you made now will still work just fine! They’ll create some great fluffy bubbles in the tub. 🙂

Hi Holly!
We did a lot of testing on this recipe to get it just right. We don’t recommend making any substitutions, otherwise the bars may not work properly.
You can use our Liquid Castile Soap Base in other projects though! I’ll include some tutorials with it below. 🙂

Jennifer says
Just a “heads up” to other newbies- although the “click here to add everything you need to your bag” makes it seem like it’s adding everything you need- but it doesn’t. You also need preservative for the color (apparently this helps keep the finished product from molding?). I didn’t know I needed it until I was diluting the color. Sigh. A small dropper would also be helpful. In addition, although a sample was promised, I didn’t get one and was ridiculously disappointed. Haha. The recipe was great and my kids used a wet bar tonight for their bath- bubbles and fun color. 🙂 It was easy to follow and the rolling was a breeze. I used parchment paper as I didn’t have freezer paper- no problem at all.
Kelsey says
Hi Jennifer!
The LabColor does need a preservative when it’s being diluted in water. I’m sorry for the confusion Jennifer. I went ahead and bolded the section labeled “Diluting LabColor” to make it a bit more clear. I also added 10 droppers to this kit to make that dilution process a bit easier. Thanks so much for the feedback.
Also, I am so sorry that sample was missing. I would recommend checking the gray foam packaging in the box. The sample bottles are quite small, so they can get lost in there.
If that sample isn’t in that packaging, we can send you two samples on your next order to make up for that missing one. To get that extra sample, email [email protected] within one business hour of placing the order. You can say Kelsey said you can have an extra one. 🙂
So glad your kids enjoyed the bars! If you have any other questions or concerns, please let me know.

Suzanne says
I made these bars and put them on wax paper to dry. On day 3 or 4 they went from pink and blue to a brown color. Could this be the wax paper? I used pink mica and lab blue for the colors.
thanks, Suzanne
Kelsey says
Hi Suzanne!
Hmm, I’m wondering if it may be fragrance discoloration. Fragrances that contain vanilla can sometimes discolor products. You can read more about discoloration here: http://www.soapqueen.com/bath-and-body-tutorials/tips-and-tricks/why-did-my-soap-turn-brown/
What fragrance did you use for these bars? Let me know and we’ll get this figured out. Thanks Suzanne! 🙂

I used clean linen and the same thing happened to me !
Lisa says
I made these last night following the recipe to the “T” (except I used Sweet Pea fragrance oil). They are drying out really nice. I was a little apprehensive after reading other comments about it being to wet, but I think I made a successful batch. Looking forward to experimenting with different colors and scents. Thanks Bramble Berry!!!
verica says
I just made this recipe today, excellent results! The most difficult part of making these is deciding on a scent. I just used the Relaxing fo I got in my sampler purchase, and I am not so sure I like it. Smells masculine to me. Thanks BB for the tutorials!!!!
verica says
Someone please tell me how to leave my own comment vs replying to one….that was not what I had intended.

Robin says
Hi bramble berry, I made this recipe for a nice valentines present for my self today (ha ha)!!
Anyway, actually I really made this recipe because I’m experimenting making new bubble bar recipes this week, so far I have made (2 different type cherry vanilla truffle bars, and loveSpell bubble bars).
I’m thinking of maybe using orange cream next, or maybe bramble Berrys blackberry fragrance.
This recipe turned out nice, except I think I use the wrong purple because it was almost all the same color, so It turned out only one color ( almost all hot pink )
But It smells great!!!
Next time I’ll use a different purple.
Kelsey says
That’s awesome Robin, so glad the bars turned out well! Experimenting with this recipe is super fun, and as a bonus you get a nice bubble bath. Orange cream or blackberry sound lovely. Have fun trying new scents and colors! 🙂
Also, did you use LabColors for the purple? If so, were they diluted? Let me know!

Gi get says
How long do they take to dry.
Kelsey says
Hi there!
These bars take anywhere from 3 days to a week or so to dry! It depends on your climate. For instance, if you live in a more hot and humid place, they can take a bit longer to dry. They dry best in a cool, dark place with good air flow, like a garage or basement. 🙂
-Kelsey with Bramble Berry
Gi get says
Ah. Well with winter in so Texas there’s not much humidity right now. I made a batch almost 12 days ago and they still are soft underneath. What should they dry on? Should I put them in a dehumidifier to dry them out?
Kelsey says
You can use a dehumidifier if you like! You can also use your oven. Preheat the oven to 200F. When it’s preheated, turn it off and pop the bubble bath in there for 15 minutes. That should help dry it out. 🙂
-Kelsey with Bramble Berry
Gi get says
I read about trying this after I wrote the above note. It didn’t really work. They are still a little soft. Boo.
Thank you though!
Kelsey says
I’m so sorry about that! The bars can be a bit soft in more humid areas, but should dry fairly quickly in more dry areas. Did you make any substitutions to the recipe? Also, where are you storing your bars?
-Kelsey with Bramble Berry
Rhonda says
Can you use the oven right after their made or do you need to wait for a few days first?
Kelsey says
Hi Rhonda!
We recommend waiting 5-7 days before popping them in the oven. They typically dry at room temperature, but if they’re still wet after a week, you can use the oven. 🙂

wallis lahtinen says
How much of the bubble bar
per bath do you use? 4 oz seems a lot for one bath or am I misunderstanding something?
thanks,

Kelsey says
Hi Wallis!
You can use the whole bar if you want a super bubbly bath! If not, you can break it in half and save the rest for later. Either way works just fine. 🙂

Hayley says
Hi! I’m just wondering what the purpose of the cream of tartar is. Is it for pH or does it do something else in the recipe? Thank you!

Cream of tartar helps stabilize the bars and helps them hold their shape. We love it in this recipe. 🙂

Want to try bubble bars and have purchased the materials for the blue and green original recipe – why are the lab color volumes lower lower in this recipe?
Thanks for any tips for the first time.
Kelsey says
Hi Marissa!
We found 12 mL and 6 mL of color for this recipe was just perfect! We love the romantic and sort of pastel look of these bars. With the other recipe, we found a bit more color gave us the lovely blue and green color scheme we wanted. Feel free to add more or less if you like! It’s definitely personal preference. 🙂

Angie says
What is the shelf life on prepared bubble bars? If they are stored in air tight bags, etc, how long should they remain stable/usable? Thank you!
Kelsey says
Hi Angie!
These bars should last about a year or so! We recommend wrapping them tightly in plastic wrap and storing them in a cool, dry place. That will help keep them nice and fresh. 🙂

Rachel says
If you were to use micas instead of lab colors, how much would that affect the bubble bars since they are dry? I have a lot of micas but do not have any lab colors as of right now. How much mica would be suggested to add to this? Thanks!
Kelsey says
Hi Rachel!
That’s a great question! We noticed when the LabColors were added, it did help moisten the bars. That means with mica, the batch may be a little bit more dry.
I would recommend starting out with about 1/2 tsp. of mica to the batch. If you want it a little darker, you can add more color. Keep in mind the more color you add, the more likely the bars will color the tub. The good news is that color should wipe away with a paper towel. 🙂
After you’ve added your colors, the dough should feel slightly sticky and wet (you can see that texture in the video: http://www.soapqueen.com/bath-and-body-tutorials/bath-fizzies/how-to-make-solid-bubble-bath-on-soap-queen-tv/)
If your dough is on the dry side, you can add a bit more glycerin to the mix. I would recommend starting with a couple drops, then adding more as necessary. If you live in a fairly humid climate, you can make the dough a bit more dry, as the moisture in the air will make the bars a bit more wet automatically. 🙂

Marvel says
The recipe says that it makes 8 bars, how many ounces are the bars?

Hi Marvel!
The bars weigh about 4 ounces! That will vary slightly depending on how thick they’re cut. Ours are about 1″ thick. 🙂
-Kelsey with Bramble Berry
Kellie says
how would you dilute your micas?
Sly says
You could add the mica directly into the dry ingredients or mix with a little of the glycerin.
Marvel says
The mica is sprinkled on top of the bar, so its not diluted. The color in this recipe is from the lab colors
Kelsey says
Hi Kellie!
If you want to add micas to this recipe, you can add them directly to the dry powder. They don’t need to be diltuted like the LabColors! They add great color and a bit of shimmer to the recipe. They also look great sprinkled on top of the bars. 🙂

Shannon says
Hi, I’ve been thinking about making these, but I’m a little intimidated by the rolling process. Would it work to put the dough in a silicone mold of individual squares? Or does the rolling serve a purpose in the texture of the finushed product?
Thanks, Shannon
Marvel says
I use parchment paper with a LIGHT sprinkling of baking soda. You could scoop them out and make “ice cream scoops”
Shannon says
Oh YES! That sounds like a fun, awesome idea! Thanks for the reply, I’m writing that in my idea book right now!
Kelly says
You can also use cookie cutters to create shapes. Take a chunk of the dough, put it into the cookie cutter, and lightly press the dough down to fill the cutter and get the shape. Carefully remove the cutter, then use it for the next one. As far as I have noticed, rolling the dough has no effect on the texture. It’s just a way to get the jelly roll swirl look.
Shannon says
I have some really cute cookie cutters, so that’s a wonderful idea! The possibilities are endless! I’m not so sure about the jelly-roll method, so I’m grateful for the additional ideas. Thank you!
Kelsey says
Thanks for your amazing ideas Kelly and Marvel! I love the idea of using ice cream scoops or cookie cutters. 🙂
I would recommend using those suggestions Shannon, rather than popping the solid bubble bath in molds. Because it’s wet and sticky, it may not want to come out of molds. Also, it may take longer to dry in there. We haven’t tried this recipe with scoops or cookie cutters, so a small test batch would be very helpful!
-Kelsey with Bramble Berry
Kirsty says
I made the blue ones previously, however they never dried. I see yours look dry and cracky, mine are more like clay. They still work beautifully in the bath, but the bars have some drops on the surface (glycerin?)
I’m from the UK if it makes a difference.
Any tips to perfect the mix would be great x
Robin says
Kristy, I’ve made these a few times using this recipe and others. I’ve found that the results depend greatly on your specific climate. If you live in a more humid climate, you can try adding less glycerin and they may dry a bit harder (or they may take longer to dry). That worked for me, as did leaving them to dry in the garage rather than the kitchen (less humidity). Play around with the glycerin content and liquid vs dry ingredient amount a bit to see if that helps for you! Also these are so fun to make and use! 🙂
Kelsey says
Hi Kristy!
Robin is correct – these bars will act differently in different climates! If you live in a humid environment, they may be a bit more wet than in a drier climate. For your next batch, you can reduce the glycerin and castor oil amount slightly.
For the batch now, the oven can help dry them out! Preheat the oven to 200F. When it’s preheated, turn it off and pop the bubble bath in there for 15 minutes. That should help dry it out.
Thanks for your help Robin! Letting them dry in the less humid garage is a great idea. 🙂

Where can I find tapioca powder? The link provided in the ingredients does not take you to a product.

Martina says
What size should each bar be? Or what weight? I’ve never used them before. Is SLSA natural product? And can you use micas or oxides as colorants? Thanks.
Marvel says
SLSA is plant derived, so yes, it is considered “natural,” if you look at “all natural” LUSH products they use both SLS and SLSA to achieve the bubbles in their products. (Its also what makes your shampoo/hand soap bubble). SLS is a sulfate, while SLSA is not. HTH
Lily says
“Natural” is a umbrella term. SLSA,although it’s plant derived it went through so much processing in order to become SLSA therefore some people may not consider it to be natural. On one of brambleberry’s posts, someone asked the same question and Ann-Marie told them that she believes that SLSA is not natural as it went through a lot of processing. Hope this helps!
Kelsey says
Hi Martina!
How much they weigh will depend on how thick they’re cut! We cut ours about 1″ thick, and they weigh about 4 ounces each. 🙂
SLSA is considered a synthetic lathering agent. It adds amazing bubbles in this recipe, we love it! You can read more about SLSA here: https://www.brambleberry.com/Sodium-Lauryl-Sulfoacetate-SLSA-P5244.aspx
Also, natural is an unregulated term, and does mean different things to different people. Read more about the term “natural” here: http://www.soapqueen.com/bath-and-body-tutorials/tips-and-tricks/natural-vs-organic/
You can add micas to this recipe! They add some fun shimmer and color. We recommend adding those to the dry powder phase. As for oxides, we don’t recommend them. In the tub, they are quite streaky and can leave marks on the tub. Micas work well though: https://www.brambleberry.com/Sodium-Lauryl-Sulfoacetate-SLSA-P5244.aspx
Thanks for your help Lily and Marvel! 🙂

Eryn says
Hi Kelsey!
I try to avoid using SLS or SLSA in anything I make. Does that mean I shouldn’t try making these? Is there anything I could use instead? They’re so cute!
Kelsey says
We have found that SLS and SLSA create really nice bubbles in the tub, and haven’t found a good alternative. You can make bath fizzies instead! They use citric acid and baking soda to create a fun fizzing reaction in the tub. 🙂
