Science
Mechanism of Action
On the skin, POLYACRYLATE CROSSPOLYMER-4 forms a protective, continuous film that effectively aids in retaining moisture, particularly beneficial for dry skin. As an emulsifier, it prevents the separation of oil and water phases, ensuring product stability and uniform ingredient distribution. Additionally, it provides necessary thickness, contributes to a smooth, glossy product appearance, and can function as a mild surfactant for gentle cleansing by lowering surface tension.
