POLYMETHYL ACRYLATE.

Insufficient Data CAS 9003-21-8 / FILM FORMING

Polymethyl Acrylate is a synthesized polymer derived from acrylic acid, generally recognized for its non-irritant characteristics in its polymerized state. While its specific functional benefits for skin are not extensively detailed, it presents distinct formulation properties concerning water interaction and pH sensitivity.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Panel has not yet assessed Polymethyl Acrylate, meaning its potential for skin, eye, or lung irritation remains unassessed by this body. However, as a polymerized acrylate, it is generally considered non-irritant and non-allergenic, in contrast to acrylate monomers which can act as strong irritants and allergens.

Verdict

Insufficient Data

Given the current lack of specific clinical data regarding its skincare benefits, defined mechanisms of action, and unassessed safety status by the CIR Panel, the overall value of Polymethyl Acrylate in precision skincare remains undetermined.
