Alcohol free spray formulation
Trying to make a water based insect repellent spray but the result is creating a separation.
Here’s my formulation.35% water (distilled)
20% Oil A
20% sodium lauryl sulfate
10% Oil B
10% Oil C
5% myristic acid
Phase A
Mix the oil A,B and C together until uniform.
Phase B
Stir the myristic acid and sodium lauryl sulfate into the water.
Mix phase A and B together.
Any suggestions on what I can do to avoid separation issues?
Thanks.

Sodium lauryl sulfate shouldn’t be used in any leave-on applications. It is already too irritant in rinse off applications so imagine how harsh it would be at 20% in leave-ons.
So get rid of it and get a proper emulsifier to hold the oils and myristic acid.

Here which one will repel insects ?

Capric and lauric acid would be better insect deterrents (see for example HERE) than myristic acid but you might have to up the % . BTW capric acid stinks and you won’t just get rid of parasites but also of all your friends! :smiley:

Does it has H₂S like odour or worst ? Will Tea tree oil enhance its insects repelling job ?

I am using a combination of Citronella oil, Peppermint oil and Basil as my 3 oils as repellants.

Smells spot on like a billy goat
. Capric, caprylic, and caproic acid have their name from “capra” which is italian/latin/greek for goat because these fatty acids are constituents of glandular secretion of goats.
