Science
Mechanism of Action
This copolymer functions as a crucial binder agent, ensuring the uniform cohesion of powdered ingredients within a product. It also acts as a film former, creating a smooth, often imperceptible layer on the skin's surface. Furthermore, its role as a thickener optimizes product viscosity, while its emulsion-stabilizing properties prevent phase separation, maintaining product homogeneity and efficacy over time.
