PVM/MA Decadiene Crosspolymer Good Polymer No known benefits PVM/MA Decadiene Crosspolymer at a glance Film-forming agent in the waterless phase of a cosmetic formula Helps create gel textures that spread easily High amounts used to provide hold to hairstyling products Comes as a white powder in its raw material form PVM/MA Decadiene Crosspolymer description PVM/MA decadiene crosspolymer is a complex synthetic polymer whose primary role is film-forming agent in the waterless phase of a cosmetic formula. This ingredient also helps thicken gels and in higher amounts can provide hold to hairstyling products. According to UL Prospector (a hub of cosmetic ingredient suppliers of PVM/MA decadiene crosspolymer), it comes as a white powder in its raw material form and its “shear-thinning properties allow strong gels with quick break for processing, spreading and dispensing.” It is typically used in amounts of 2% or less, as these amounts have proven to be non-sensitising on human skin. The very large molecular size of PVM/MA decadiene crosspolymer keeps it firmly on skin’s surface.
