ISOBUTYLENE/ISOPRENE COPOLYMER.

Insufficient Data CAS 9010-85-9 / VISCOSITY CONTROLLING

ISOBUTYLENE/ISOPRENE COPOLYMER is a synthetic polymer primarily utilized in non-aqueous cosmetic formulations to manage and improve product consistency. It forms a resilient, protective barrier on the skin, demonstrating impermeability to water and air, which suggests film-forming and occlusive characteristics.

Viscosity Controlling Viscosity Enhancing Film Former Occlusive

Science

Mechanism of Action

This copolymer's primary function is to serve as a viscosity controlling and enhancing agent, particularly within non-aqueous cosmetic systems. Upon application, it establishes a protective film on the skin's surface. This barrier is noted for its resistance to air, water, and certain chemicals, implying an occlusive action that can minimize transepidermal water loss. Its use in adhesive contexts also suggests a capacity to potentially mitigate skin irritation.
