SODIUM ACRYLOYLDIMETHYLTAURATE CROSSPOLYMER.

Valuable / EMULSION STABILISING, VISCOSITY CONTROLLING

Sodium Acryloyldimethyltaurate Crosspolymer is a sophisticated synthetic polymer engineered to enhance the texture and stability of skincare formulations. It acts as an effective thickening agent and emulsion stabilizer, providing a smooth, silky feel while contributing to the overall integrity of the product.

Summary

Viscosity controlling Emulsion stabilizing Film-forming Texture enhancer

Science

Mechanism of Action

Operating as a highly efficient rheology modifier, Sodium Acryloyldimethyltaurate Crosspolymer primarily controls viscosity and stabilizes emulsions by preventing the separation of oil and water phases. Its pseudoplastic behavior allows formulations to thicken at rest for optimal stability, yet thin under shear for effortless, even application. On the skin, it forms an imperceptible film that supports moisture retention, contributing to sustained hydration.

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that acryloyldimethyltaurate polymers, including this crosspolymer, are safe for use in cosmetics under current practices. As a large molecule, it is not expected to be absorbed through the skin. Formulators are advised to adhere to good manufacturing practices (cGMPs) to ensure residual acrylamide levels in finished products remain below 5 ppm.
