Science

Mechanism of Action

As a crosslinked polymer, Polyacrylate Crosspolymer-7 functions primarily as a highly efficient thickening and emulsifying agent. It precisely controls product viscosity to achieve desired consistencies, ranging from liquids to semi-solids. By stabilizing the oil and water components, it prevents phase separation and ensures a homogenous distribution of active ingredients. It further enhances product texture, imparting a smooth, glossy appearance, and can form a protective, water-retaining film on the skin.

Stability

Polyacrylate Crosspolymer-7 is water-soluble and capable of forming gels at higher concentrations. It exhibits robust stability across a broad pH range of 2-8 and demonstrates high resistance to electrolytes, tolerating up to 10% salt concentrations. This ingredient is also pre-neutralized for ease of formulation.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

A direct CIR (Cosmetic Ingredient Review) safety assessment specifically for Polyacrylate Crosspolymer-7 is not available. However, a closely related ingredient, Polyacrylate Crosspolymer-6, was deemed safe by the CIR Expert Panel for current practices of use and concentration, with a highest reported use of 5% in mascaras. Dermal irritation studies for Polyacrylate Crosspolymer-6 in rabbits indicated non-irritating effects at concentrations exceeding 90%. A human repeated-insult patch test (HRIPT) for Polyacrylate Crosspolymer-6 at approximately 5% showed it to be non-sensitizing and non-irritating. Ocular irritation tests in rabbits considered Polyacrylate Crosspolymer-6 to be slightly irritating, though an in vitro test at 2% predicted non-irritation. Legal requirements mandate rigorous product safety assessments for all cosmetic ingredients, including Polyacrylate Crosspolymer-7.
