Science
Mechanism of Action
Functioning primarily as a thickening, gelling, stabilizing, and film-forming agent, Polyacrylate-44's large molecular structure prevents skin penetration. Instead, it creates a surface barrier that actively locks in moisture, significantly reducing transepidermal water loss (TEWL) to boost skin hydration and overall product sensory experience. Its amphiphilic nature, derived from both hydrophilic and hydrophobic components, also contributes to emulsion stabilization.

Stability
Polyacrylate-44 exhibits increased viscosity and stability within a neutral to slightly alkaline pH range, specifically between 6.0 and 9.0. Optimal stability is often observed around pH 7-9 for typical solutions, leveraging its complex copolymer structure with both hydrophilic and hydrophobic characteristics for robust emulsion stabilization.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed acrylates copolymers, a broader category including Polyacrylate-44, safe for cosmetic use provided formulations minimize skin irritation. A related polymer, Sodium Polyacrylate, is considered safe at concentrations up to 3%. Dimethicone, a component of Polyacrylate-44, is recognized by the FDA as a skin protectant.
