Science
Mechanism of Action
This copolymer primarily enhances cosmetic product integrity and performance. As a binder, it effectively holds diverse ingredients together within a formulation, preventing separation. Its film-forming capabilities create a smooth, invisible barrier on the skin's surface, which can aid in moisture retention. Furthermore, it acts as a viscosity controller and suspension stabilizer, ensuring consistent product texture and preventing active ingredients from settling. The ingredient's ability to rapidly absorb water also supports skin hydration by forming a gel that protects against dehydration.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed a broad category of 126 acrylates copolymers, which includes SODIUM ISOOCTYLENE/MA COPOLYMER, safe for cosmetic use under current practices and concentrations, provided they are formulated to be non-irritating. High purity is crucial to minimize irritating monomer residues. Maximum use concentrations for related acrylates copolymers in skin-contact products are up to 25%. The SCCS has not issued a specific opinion on this ingredient, and FDA permits related PVM/MA Copolymer.
