Science
Mechanism of Action
Functioning as a superabsorbent polymer, Polyacrylate-18 effectively increases the viscosity of water-based systems, transforming product textures into a desirable gel or cream consistency. It achieves this by absorbing substantial amounts of water, potentially 100 to 1000 times its mass. Additionally, it stabilizes oil-in-water emulsions and creates a thin, protective film on the skin's surface, which aids in conditioning and barrier support.

Stability
This polymer is generally stable, with its swelling performance being most effective within a pH range of 5 to 9, peaking around pH 6. Related polyacrylates also show good stability across wide pH ranges.
Safety
Safety Profile
While POLYACRYLATE-18 itself lacks an individual review, the CIR Expert Panel deems 'Acrylates Copolymers' and 'Sodium Polyacrylate' safe for cosmetic use, provided they are formulated to be non-irritating. The FDA also recognizes the safety of Sodium Polyacrylate for specific food applications.
