POLYACRYLATE-3.

Valuable CAS - / VISCOSITY CONTROLLING

POLYACRYLATE-3 is a versatile synthetic polymer primarily functioning as a viscosity-controlling agent, effectively thickening and enhancing the texture of cosmetic formulations. It also creates a protective, hydrating film on the skin's surface, improving moisture retention and safeguarding against external stressors.

Science

Mechanism of Action

Upon topical application, POLYACRYLATE-3's substantial molecular size prevents epidermal penetration, ensuring its action remains on the skin's outermost layer. Here, it forms a cohesive, gel-like barrier that efficiently attracts and retains atmospheric moisture, significantly boosting skin hydration and mitigating transepidermal water loss (TEWL). This surface film concurrently provides a physical shield against environmental irritants, contributes to a visibly smoother and glossier skin finish, and can facilitate the controlled release of co-formulated active ingredients.

Stability

Polyacrylate polymers, including POLYACRYLATE-3, exhibit robust chemical stability and minimal reactivity across a broad range of conditions. Optimal performance, particularly regarding swelling and viscosity, is observed within a pH range of 5.0 to 9.0. While highly alkali-resistant, extreme alkaline conditions may increase viscosity. Heat, neutral salts, and organic acids have negligible impact on its rheological properties. Formulators should be aware that impurities within the polymeric material could potentially accelerate the hydrolysis of sensitive active ingredients. Physical instabilities are more likely to arise from improper coating suspension formulations or incomplete film formation.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has determined that POLYACRYLATE-3, as part of the acrylates copolymers class, is safe for cosmetic use under current practices and concentrations, provided formulations are non-irritating. The FDA also recognizes the safety of related polyacrylates for cosmetic and non-cosmetic applications when irritation is avoided. Its non-penetrating nature further supports a low risk profile.
