Science
Mechanism of Action
METHACRYLOYL ETHYL BETAINE/ACRYLATES COPOLYMER functions primarily by forming a cohesive, uninterrupted film or barrier on the skin's surface. This film provides a smooth tactile sensation and enhances a formulation's ability to resist water. Additionally, it acts as an effective emulsion stabilizer, preventing ingredient separation, and as an aqueous viscosity-increasing agent, improving the product's consistency and feel.

Stability
This betaine-containing polymer is readily water-soluble and maintains its solubility across both acidic and alkaline pH ranges. It demonstrates robust stability, being generally unaffected by various additives and resistant to precipitation, even with the inclusion of electrolytes.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that this ingredient, along with 125 other acrylates copolymers, is safe for cosmetic use when formulated to be non-irritating. For leave-on products with dermal exposure, the maximum reported concentration is 25%. While residual monomers may be present, their levels in cosmetic products are considered too low to pose a safety risk.
