Lotion Emulsifier Guidelines with Active Ingredients?
Hi there,
I was wondering whether anyone could share thier insights into whether there are any rules for determining incompatibilities between emulsifiers like Polawax, Ritamulse SCG, BTMS-50, BTMS-22 and active ingredients like plant extracts?
I am currently thinking of using BTMS-50 as my emulsifier and wanted to be sure that it won’t inactivate any actives in my lotion like essential oils or green tea extracts. I know BTMS-50 contains behentrimonium methosulfate, a cationic quaternary compound.
Is there general rule about combining cationic ingredients and actives? I know that they can inactivate some preservatives.

Here’s the thing - 99% of “active” ingredients, like essential oils or plant extracts, do absolutely nothing. This is actually a good thing, because if they did really effect the body, it would be illegal to use them in cosmetics in the US.
Make a good emulsion, get it stable, and don’t worry about the “active” ingredients.
