Science
Mechanism of Action
This copolymer acts by forming a continuous, flexible film on the skin's surface, which helps to minimize transepidermal water loss and offers a degree of protection against minor environmental irritants. Beyond its barrier-supporting role, it serves as a bulking agent to optimize product density and can contribute a mild abrasive action for surface refinement. Critically, it enhances the aesthetic and tactile properties of formulations, imparting elasticity, a silky-smooth feel, and improved spreadability while stabilizing viscosity.
