Film-forming Binding Hair Fixing Antistatic

Science

Mechanism of Action

Upon application, SODIUM BUTYL ESTER OF PVM/MA COPOLYMER establishes an invisible, cohesive film across the skin. This polymeric network functions as a physical shield, thereby reducing moisture evaporation and supporting the skin's natural barrier function. Additionally, it acts as a binder, ensuring the stability and homogeneous distribution of other ingredients within cosmetic formulations.
