Pour the distilled water into a heat-safe container. Heat in the microwave until it is about about 160–180° F.
In a separate heat-safe container, combine the moringa seed oil, cetearyl alcohol and BTMS-50. Heat the container in the microwave using 30–60 second bursts until the waxes have fully melted and the mixture is about 180° F.
Check the temperatures of both containers. Each container should be about 160°–180° F. Once they are the correct temperatures, pour the oils and wax into the water and begin pulsing the stick blender. Blend the mixture for 60–90 seconds, making sure the oil and water phases are fully emulsified. Be careful to “burp” your stick blender by tamping it on the bottom of the container to release any bubbles — you don’t want bubbles trapped in your conditioner.
Continue stick blending until the temperature drops to about 130–140° F. Add the ginger essential oil. Stick blend until completely combined.
Once the mixture falls below 120° F, add the Optiphen. Using the stick blender, mix for an additional 60–90 seconds until everything is completely mixed.
Pour the mixture into jars. Let the jars sit overnight without the lids on (otherwise, condensation can form inside the jars). Once the mixture is completely cooled, shut the jars and enjoy!
