Phenoxyethanol & Caprylyl Glycol heat stability
Hello, recently I’ve started to formulate my own cosmetics from home. I did a batch of lipgloss where I heated my ingredients together over a double boiler at a temperature of 80-100C. I was wondering what that would’ve done to my Phenoxyethanol and Caprylyl Glycol that was in there? Would it have degraded completely or is there a chance it would still have some antimicrobial properties? Also, it was heated for around 20-30 minutes.
I now know I’m supposed to add my preservatives during the cool down phase but unfortunately I only learned that after I had heated my formula. Total newbie here! 🙂
