Mechanism of Action
SODIUM ACRYLOYLDIMETHYLTAURATE/VP CROSSPOLYMER functions as an efficient rheology modifier and gelling agent, especially within aqueous systems. It significantly increases product viscosity, imparts a desirable silky texture, and stabilizes oil-in-water emulsions, preventing phase separation. This stabilization is crucial for maintaining the consistent delivery and efficacy of active ingredients in formulations like sunscreens or antioxidant serums.

Stability
This pre-neutralized, synthetic polymer is cold-processable, simplifying its integration into formulations. It exhibits excellent yield value, providing superior stability even when used as the sole emulsifier. Its favorable shear-thinning and viscoelastic properties contribute to refined product textures. For optimal dispersion, it can be added to the oil phase with gentle agitation, provided the mixing vessel is completely dry to prevent premature gelling. It is suitable for both direct and inverse emulsification methods.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that acryloyldimethyltaurate polymers, including this crosspolymer, are safe for use in cosmetics under current practices. Being a large molecule, it is not expected to be absorbed through the skin. Formulators are advised to follow good manufacturing practices to minimize residual monomers and impurities, such as acrylamide, which is limited to 5 ppm in similar polymer systems. General recommended usage levels for this raw material typically range from 0.5% to 1.2%.
