The Introduction of Polyvinylpyrrolidone :
PVP K is a hygroscopic polymer ,supplied in white or creamy white powder,raning from low to high viscosity & low to high molecular weight with solubility in aqueous and organic solvents,each characterized by K Value.PVP K is Solubility in water and many oter organic solvents.,Hygroscopicity,Film former ,Adhesive,Intial tack ,Complex forma-tion,Stabilization,Solubilization,Crosslinkability ,Biological compatibility andToxicological safeness.
Polyvinylpyrrolidone(PVP) are existing as powder and water solution form,and being supplied in a wide molecular weight range,easily dissolve in water,alcohol and other organic solvents,highly hygroscopicity,excellent film-forming capacity,adhesiveness and chemical stability,none toxicity.Cosmetic Grade PVP are widely used in hair care,skin care and oral care products,especially for hair styling products.In view of it's wide molecular weight range,from the low molecular weight to high molecular weight PVP applicable for soft to hard hair care products' formulations.
The Application & Function of Polyvinylpyrrolidone :
Cosmetic Grade PVP products are suitable for fourmulations which used as film forming and viscosity modification/Thickener,especially in hair styling products,mousse gels and lotions & solution,PVPs also used as dispersion agent in Hair-dying,pigment products' formulations.Thickening agent for oral and optical preparations.
