Sodium PVM/MA Decadiene Crosspolymer
What is Sodium PVM/MA Decadiene Crosspolymer?
Sodium PVM/MA Decadiene Crosspolymer is a synthetic crosspolymer formed from the copolymerization of polyvinyl methyl ether (PVM), maleic anhydride (MA), and 1,7-octadiene, neutralized with sodium hydroxide. It functions primarily as a film-forming agent, thickener, and stabilizer in skincare formulations, creating a flexible, water-resistant film on the skin that enhances product texture and delivery of active ingredients. This ingredient is commonly used in sunscreens, moisturizers, and hair care products for its ability to improve spreadability and provide a smooth, non-greasy finish.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Film former
Creates a continuous film on skin or hair to improve wear, water resistance, transfer resistance, shine, or hold in sunscreens, makeup, and styling products.
