Science
Mechanism of Action
As a multifunctional binding and film-forming agent, POLYACRYLATE-21 deposits a continuous, imperceptible film on the skin's surface. This polymeric matrix contributes to the structural integrity and viscosity of formulations, while also establishing a superficial barrier that helps to reduce transepidermal water loss, thereby offering an indirect moisturizing benefit.

Safety
Safety Profile
POLYACRYLATE-21, as part of the broader polyacrylate class, is deemed safe for cosmetic use by the Cosmetic Ingredient Review (CIR) Expert Panel, provided it is formulated to be non-irritating. The ingredient is listed as 'Irritant Free' by SkinSAFE. While no specific maximum concentration for POLYACRYLATE-21 alone is provided, related acrylate copolymers have been safely used up to 25% in face and neck products, and up to 98.6% in nail extenders.
