ACRYLAMIDE/SODIUM ACRYLATE COPOLYMER.

Valuable CAS 25085-02-3 / ANTISTATIC, FILM FORMING

Acrylamide/Sodium Acrylate Copolymer is a synthetic polymer that acts as a film-former and viscosity-controlling agent. It enhances product texture, stabilizes emulsions, and helps reduce transepidermal water loss on the skin.

Summary

viscosity controlling film forming antistatic

Science

Mechanism of Action

This polymer forms a protective, non-occlusive film on the skin's surface, effectively reducing transepidermal water loss and locking in moisture. It also functions as an emulsion stabilizer, preventing phase separation in formulations.
