Science
Mechanism of Action
As a super-absorbent polymer, Polyacrylate-27 acts by forming a breathable film on the skin's outermost layer. This film establishes a protective barrier that helps to retain moisture, thereby reducing transepidermal water loss and conditioning the skin. Its substantial molecular size ensures it remains on the surface and does not penetrate the skin.

Stability
While specific optimal pH for Polyacrylate-27 formulation stability is not extensively detailed, related polyacrylates suggest a pH greater than 7 for analytical integrity. During the manufacturing synthesis, pH adjustments may reach 12-12.5.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Sodium Polyacrylate, a chemically related polymer, safe for use in cosmetics when properly formulated to be non-irritating. Polyacrylate-27, owing to its large polymer size, is not expected to irritate the skin itself. However, residual acrylic acid, a byproduct from the manufacturing process, could potentially cause mild skin irritation if present in concentrations exceeding approximately 300 PPM.
