Science

Mechanism of Action

Upon application, this polymer forms a microscopic film on the skin, creating a barrier that contributes to a smooth feel and can improve the longevity of cosmetic products. Its polymeric structure also functions to increase the viscosity of formulations, thereby improving texture. This film-forming property further aids in imparting water resistance to various formulations.

Stability

While certain related acrylate copolymers show stability across all pH values, this polymer can be rendered water-soluble or dispersible by neutralizing its carboxyl groups with a suitable water-soluble base. It can be integrated into the hot oil phase, or pre-mixed with solvents such as glycerin, propylene glycol, or alcohol before incorporation, requiring slow addition with vigorous agitation.
