Lotion Emulsifier Guidelines with Active Ingredients?
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.
