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.
