phase separation in anhydrous scrub
Hello, I made an anhydrous body scrub that showed phase separation after stability test (1 month 35°C (control 25°C)+centrifugation 3000rpm/30min: phase separation, odour not comparable to standard and pH from 5.1 to 4.3 and viscosity decreased too), similar results with cycling of temperature (-20C/ 24h + 25C/ 24h).
I believe I made a mistake using that emulsifier, would just Sorbitan Olivate work better?, and that grape seed oil is too high and went rancid despite vitamin E? I appreciate very much any suggestion! Thanks!
