GLYCERYL POLYACRYLATE.

Valuable CAS 104365-75-5 / FILM FORMING

Glyceryl Polyacrylate is a versatile polymer known for its hydrating and texture-enhancing properties, forming a moisture-retaining film on the skin while improving product consistency.

Film-forming Humectant Viscosity increasing agent Thickening agent Hydrogel former

Science

Mechanism of Action

This ingredient primarily functions by creating a protective, thin film on the skin's surface, which effectively reduces transepidermal water loss and locks in natural moisture. As a potent humectant, it actively attracts and binds water, providing sustained hydration to the skin. It also forms a hydrogel, which is adept at delivering water-based moisturizing components efficiently. Furthermore, Glyceryl Polyacrylate acts as a rheology modifier, thickening cosmetic formulations and imparting a desirable smooth, slippery skin feel.
