Science
Mechanism of Action
This polyacrylate operates by forming a robust, stable gel network when dispersed in water. This network efficiently traps water molecules through osmotic principles, which not only enhances the texture and stability of a product but can also establish a thin, protective film on the skin's surface, aiding in moisture retention.

Stability
Polyacrylates are generally water-soluble polymers. While a precise optimal pH range for Polyacrylate-29's stability has not been identified, related polyacrylates are known to be pH-responsive, with factors such as polymerization rates and molecular weight being influenced by pH. For instance, an increase in pH from 4 to 7 can enhance the polymerization rate of polyacrylic acid.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Polyacrylate-29, among 126 acrylates copolymers, is safe for use in cosmetics under current practices and concentrations, provided formulations are non-irritating. Cosmetic-grade sodium polyacrylate, a related compound, is considered non-toxic and adheres to stringent safety regulations by the FDA and EU Cosmetics Regulation, also being deemed safe for sensitive skin types. Typical usage concentrations for sodium polyacrylate range from 0.1% to 3%. Furthermore, polyacrylates are recognized by the FDA in its Inventory of Food Contact Substances (21 CFR Part 176.1705).
