Science
Mechanism of Action
This copolymer primarily functions by forming a continuous, resilient film upon application to the skin. This film not only imparts water resistance to cosmetic formulations but also contributes to a noticeably smoother and softer skin sensation. Beyond its film-forming capabilities, it effectively increases product viscosity, stabilizes emulsions, and acts as a general skin-conditioning agent, improving the overall sensory experience and feel.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed this copolymer's safety in cosmetics at current usage levels. A critical safety parameter involves ensuring the residual acrylamide monomer, an impurity, remains below 5 ppm as per CIR guidelines. The European Commission's SCCS further restricts this residual acrylamide to a maximum of 0.1 mg/kg in leave-on body care products and 0.5 mg/kg in other cosmetic formulations. Its large molecular weight is theorized to prevent dermal absorption, reinforcing its safety. FDA VCRP data confirms its use, even in sensitive categories like baby products.
