I need your help in solving a problem with the clouding of the opacifier in a shower gel formula.
Indeed, I use in my shower gel formula 0.2% opacifying (styrene acrylate copolymer) diluted with a coefficient: 1: 4
My formula contains:
Sodium laureth sulfate 70%: 10%
Coacamidopropyl betaine 30%: 5%
Cocamide DEA: 2%
citric acid: 0.1
Conservative: MCIT & MIT: 0.1%
Decyl glucoside: 1%
Sodium chloride: 1.7%
After a certain time at room temperature (1 month and more), we notice a phenomenon of non-stability of the opacifier: a transparent layer at the bottom or a white layer at the bottom of the bottle.
I didn't really understand what happened.
Can you guide me to solve this problem
