Acrylates Copolymer Cloudiness After pH Adjust
I’m formulating a hand wash with exfoliants suspended with acrylates copolymer. Unfortunately, my perfectly clear formulation turns cloudy as soon as I adjust the pH. Any ideas?
Replicating the issue:
Water: 41%
SLES (28%): 36%
Coco Betaine: 8%
Acrylates Copolymer: 3%
Sodium Lauroamphoacetate: 6%
Glycerine: 4%
Saccharomyces Ferment: 2%Process is: combine water, SLES, and acrylates copolymer. Dissolve acrylates copolymer at 80c, adjust to neutral with TEA, then mix at 80c for 20 min. The other ingredients are added after.
The formulation is clear and viscous, but the pH is 7.2. As soon as I add either citric acid, lactic acid, or even a lactic acid solution, the formulation becomes a milky white. Any idea how to avoid this?
