PVM/MA DECADIENE CROSSPOLYMER.

Valuable CAS 136392-67-1 / BINDING, FILM FORMING, VISCOSITY CONTROLLING

PVM/MA Decadiene Crosspolymer is a versatile polymer engineered to enhance formulation stability and deliver a smooth skin feel. It functions as a film-forming agent, creating a protective layer that helps bind water to the skin, preventing dryness and imparting a silky texture. Additionally, it optimizes product viscosity, ensuring an ideal spreadability and consistency.

Summary

film-forming viscosity controlling binding

Science

Mechanism of Action

This ingredient operates on multiple levels within a cosmetic formulation and on the skin. As a binding agent, it helps coalesce other ingredients, maintaining product integrity. On the skin, it forms a continuous, protective film that actively binds water, thereby preventing moisture loss and contributing to a supple, smooth sensation. Concurrently, its role as a viscosity-controlling agent thickens solutions, improving texture and enabling effortless application of the product.

Stability

A water-loving polymer, it disperses readily in water to form clear, aqueous gels at concentrations as low as 0.25-0.50%. These gels demonstrate robust stability against shear and temperature variations. It provides exceptional thickening, suspending, and stabilizing capabilities in both aqueous and non-aqueous systems, maintaining efficacy even at low concentrations or low pH values, while also contributing to an excellent skin feel and emulsion stability.
