Since you’re combining essential oils and water in this recipe, you need polysorbate 80 to help combine the essential oil and the water. In a glass container, combine the polysorbate 80 and the essential oils and mix well.

In a separate glass container, add the hydrogen peroxide, vinegar, 99% isopropyl alcohol and water. Mix well.

Using droppers, add the Optiphen ND and Natural Castile Liquid Soap Base and mix. Because this mixture contains water, it needs a preservative to prevent mold and bacteria.

Add the polysorbate and essential oil mixture and mix until the spray is clear. That will take around 30-60 seconds.

Pour the mixture into bottles and it’s ready to use right away!
