Science
Mechanism of Action
This copolymer functions through its polymeric structure to create a continuous film on the skin's surface, contributing to the product's longevity and tactile feel. In powdered formulations, it ensures particle cohesion. Furthermore, it precisely controls the rheological properties of a cosmetic, allowing for tailored viscosity levels. Due to its substantial molecular size, percutaneous absorption into the skin is not anticipated, rendering it a physically active but biologically inert component.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that this copolymer, categorized within a group of polyenes, is safe for use in cosmetics under current practices. This assessment is based on structural and physiochemical similarities to related polyenes, some of which are used at high concentrations (e.g., hydrogenated polyisobutene up to 95%, polyethylene up to 67.6%). Its high molecular weight prevents percutaneous absorption, contributing to its inertness on the skin.
