Science
Mechanism of Action
This branched acrylate copolymer operates by forming a continuous, microscopic film on the skin's surface, acting as a barrier to minimize transepidermal water loss and offer protection. Its chemical structure, featuring both hydrophobic and hydrophilic domains, allows it to exist as a tightly coiled dispersion in acidic water, uncoiling and swelling as pH increases to enhance viscosity. Beyond its film-forming capabilities, it effectively thickens formulations, stabilizes emulsions by preventing ingredient separation, and contributes to a smooth, silky, and glossy product feel.

Safety
Safety Profile
The CIR Expert Panel deems crosslinked alkyl acrylates, including Polyacrylate-2 Crosspolymer, safe under current usage conditions and concentrations, provided they are not polymerized in benzene. Products formulated with this ingredient are generally considered non-irritating. EWG identifies low concerns for cancer, allergies, and developmental toxicity, though it notes high use restrictions.
