ETHYLENE/VA COPOLYMER.

Valuable CAS 24937-78-8 / BINDING, EMULSION STABILISING, FILM FORMING

ETHYLENE/VA COPOLYMER is a versatile polymer engineered to form a protective, continuous film on the skin. This film not only aids in reducing moisture loss but also enhances product texture and stability by acting as a binding and emulsion-stabilizing agent within cosmetic formulations.

Summary

binding emulsion stabilising film forming

Science

Mechanism of Action

This copolymer primarily operates by forming a thin, occlusive film on the skin's surface. This physical barrier demonstrably minimizes transepidermal water loss (TEWL), thereby improving skin hydration and imparting a smooth tactile sensation. Beyond its film-forming capabilities, it functions as a critical binding agent, ensuring the structural integrity of powdered cosmetic products, and as an emulsion stabilizer, which is crucial for maintaining the homogeneity and prolonging the shelf-life of complex formulations.
