Science

Mechanism of Action

This polyacrylate crosspolymer primarily functions by increasing product viscosity and stabilizing oil-in-water emulsions, thereby preventing phase separation and ensuring consistent ingredient delivery. It forms a breathable film on the skin's surface, which assists in moisture retention. Additionally, some related polymers demonstrate the ability to absorb excess sebum, contributing to a matte finish on oily and combination skin types.

Stability

Polyacrylate Crosspolymer-12, similar to its related counterpart Polyacrylate Crosspolymer-6, exhibits robust stability across a wide pH range, specifically between pH 2 and 8, and demonstrates high resistance to electrolytes. For optimal incorporation, it is typically dispersed in the aqueous phase, requiring approximately 8 hours for static hydration or about 10 minutes with mechanical blending, especially when electrolytes are present. It can effectively stabilize formulations, including those containing up to 25% oil, particularly when co-formulated with natural polymers like 1% xanthan or guar gum, by establishing a protective matrix.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated Polyacrylate Crosspolymer-12 within the broader categories of 'crosslinked alkyl acrylates' and 'acrylates copolymers,' concluding it is safe under current usage practices and concentrations, provided formulations are designed to prevent skin irritation and not polymerized in benzene. No specific maximum concentration limits are established; its safety is determined by its integration into non-irritating product formulations. No independent SCCS opinion or FDA status was identified.
