Science
Mechanism of Action
This ingredient functions by swelling in aqueous systems, which effectively increases the viscosity and stability of cosmetic products. When applied to the skin or hair, it forms a cohesive and continuous film, improving sensory attributes and reducing tackiness. It also exhibits surfactant properties, aiding in emulsification and the production of foam.

Stability
As a cross-linked polymer, ACRYLIC ACID/VP CROSSPOLYMER is generally less chemically reactive than non-crosslinked counterparts, achieving its rheological modifications by swelling in water. Its performance, particularly thickening efficiency, is often influenced by pH, though a specific optimal pH range for its stability is not detailed in current research. Related acrylic acid copolymers can exhibit stability across varied pH conditions, while some may experience hydrolysis between pH 4-9.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated ACRYLIC ACID/VP CROSSPOLYMER, concluding it is safe for use in cosmetics under current practices and concentrations. This crosslinked copolymer may contain residual monomers, with reported levels of ≤ 500 ppm for acrylic acid and ≤ 100 ppm for vinyl-pyrrolidone. Broader safety assessments for acrylate copolymers indicate safety when formulated to be non-irritating. There is no direct SCCS opinion or specific FDA approval status beyond the CIR assessments.
