FIBROIN/PEG-16/SODIUM ACRYLATE COPOLYMER.

Insufficient Data / FILM FORMING

This sophisticated copolymer integrates silk fibroin, PEG-16, and sodium acrylate to provide multifaceted benefits. It is engineered to optimize product texture, stabilize emulsions, and form a breathable film on the skin, contributing to enhanced hydration and refined sensory feel.

Science

Mechanism of Action

This ingredient functions via a synergistic combination of its constituent components. Silk fibroin contributes biocompatibility and film-forming capabilities, potentially offering a subtle scaffolding effect on the skin's surface. PEG-16 acts as a humectant, attracting moisture, and also serves as a solvent and emulsifier, aiding in uniform ingredient distribution. The Sodium Acrylate Copolymer component primarily operates as a viscosity-increasing agent and emulsion stabilizer, crucial for product consistency, while further contributing to film formation and binding. Collectively, these actions result in a moisturizing, texture-enhancing agent with potential for improved dermal interaction and controlled delivery.

Stability

The ingredient exhibits water solubility, consistent with its components: silk fibroin, PEG-16, and sodium acrylate copolymer. While a precise optimal pH range for the exact complex is not specified, the acrylate copolymer component is generally stable within typical cosmetic pH values. Rigorous purification is critical to minimize residual monomers and prevent potential irritation.

Safety

Safety Profile

CIR Status
Safe with restrictions
Max tested
25%
Sensitization risk Unknown

The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated 'Acrylates Copolymer' and 'Sodium Acrylates Copolymer', deeming them safe for use in cosmetics when formulated to be non-irritating. Concentrations may range from 0.5% for texture and stabilization up to 25% for film-forming or binding applications. A crucial restriction mandates that industry practices must ensure acrylamide monomer concentrations do not exceed 5 ppm in finished cosmetic products. Specific safety data for the exact FIBROIN/PEG-16/SODIUM ACRYLATE COPOLYMER complex is not explicitly available, with assessments largely based on the acrylate copolymer component's profile.

Verdict

Insufficient Data

While individual components possess known cosmetic benefits and safety profiles, comprehensive data for the specific FIBROIN/PEG-16/SODIUM ACRYLATE COPOLYMER complex is currently insufficient to provide a definitive efficacy or safety rating.
