Science
Mechanism of Action
This ingredient functions by creating a continuous, protective film upon application to the skin, which can help minimize moisture loss and contribute to a smoother texture. As a UV absorber, POLYACRYLATE-26 helps prevent the degradation of other cosmetic ingredients when exposed to ultraviolet light. Furthermore, like related polyacrylates, it increases the viscosity of water-based formulations, improving texture, and stabilizes emulsions by preventing ingredient separation. On the skin, this film-forming ability can enhance moisture retention and potentially aid in the more effective delivery of active ingredients.

Key findings
- 01 Studies on related polyacrylates, such as Sodium Polyacrylate, indicate efficacy in concentrations ranging from 0.1% to 3% for thickening formulations, improving texture, and enhancing skin moisture retention. These concentrations also contribute to emulsion stabilization and active ingredient delivery.
- 02 General polyacrylates are effectively utilized as film formers at concentrations exceeding 25%. Lower concentrations, approximately 0.5%, are recognized for their role as suspending agents and emulsion stabilizers.

Stability
Polyacrylates are slowly soluble in water, creating a highly viscous, transparent liquid. They demonstrate robust alkali resistance, maintaining viscosity with minimal change under alkaline conditions, and are highly stable, resisting decomposition even at temperatures up to 300°C. However, their viscosity can decrease significantly in the presence of acids or metal ions. The optimal pH range for a 1% solution of related polyacrylates is typically between 6.0 and 8.0.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Sodium Polyacrylate, a related ingredient, safe for use in cosmetics at concentrations up to 3%. Its large molecular size generally prevents significant skin penetration, reducing the risk of irritation or sensitization. However, exposure to its powdered form can cause mild irritation to the skin and eyes, and inhalation of fine particles should be avoided. A potential concern exists if residual acrylic acid from manufacturing is present above 300 PPM, which may lead to skin rash upon contact.
