SODIUM ACRYLATES/ETHYLHEXYL ACRYLATE COPOLYMER.

Valuable / FILM FORMING

Sodium Acrylates/Ethylhexyl Acrylate Copolymer is a versatile synthetic polymer that forms a continuous, protective film on the skin or hair. It enhances product aesthetics and functionality by improving texture, stabilizing emulsions, and providing water resistance.

Science

Mechanism of Action

This copolymer operates by forming a thin, uniform, and protective layer on the skin's surface. This film effectively contributes to the skin's moisture barrier, reducing transepidermal water loss and locking in hydration. Furthermore, it acts as a robust binding agent and viscosity enhancer, contributing to product stability, texture, and the improved durability of cosmetic formulations.
