Best solvent for terpenes (terpinen-4-ol and nerolidol)
Hello Chemistry Experts!
Please share with me what you think would be the best/optimal solvent for a hair serum that includes terpinen-4-ol and nerolidol.
I have tried different solvents and so far Ethylhexyl Stearate seems to work best although it is too thin and needs thickening.
I’ve also tried fractionated coconut oil with mixed results (didn’t seem to be as potent and found that some of the serum started to solidify).
For regulations purposes here n Canada, I cannot use solvents already classified as “drugs” i.e. dimethicone, isopropyl myristate.
The purpose of the serum is to kill lice. When tested on live bugs, it has immediate effect in the ethylhexyl stearate however when applied to hair of infected people, it runs down the hair shaft and thus the head lice are not sufficiently immersed and escape neutralization.
If you can suggest a better solvent and substance that would thicken to more of a gel like substance, please tell me!
Or, if the Ethylhexyl Stearate is the best solvent, how to thicken to a gel like product to trap the bugs in the hair?
Thank you for your time and suggestions ☺️
