*Cosmetic Grade VP/VA Copolymers with different rations of N-Vinylpyrrolidone to Vinyl Acetate,soluble in most organic solvents.Which exists in powder,water solution and ethnol solution form. VP/VA Copolymers’ aqueous solutions are non-ionic, neutralization not required, Resultant films are hard, glossy, and water-removable; Tunable viscosity, softening point and water sensitivity depending on VP/VA ratio; Good compatibility with many modifiers, plasticizers, spray propellants and other cosmetic ingredients,and the hydroscopicity decreases in proportion to the ration of Vinyl acetate.

Applications:
Copovidone mainly used as water-soluble binder and dry binder in wet/direct granulation processes,also it can be used as film forming materials.
*Water soluble tablet binder,suitable for wet or dry granulation/direct compression processes.
*Film Former:permeable film coating for tablet and sugar coatings to protect against splitting,decrease moisture sensitivity and provide good film adhesion.
***********************************************
*Technical Grade VP/VA Copolymers are with different rations of vinylpyrrolidone to vinyl acetate and available as white powder or clear transparent solutions in water,ethanol and isopropanol.It’s forms hard,glossy,flexible,water-removable,oxygen permeable films which adhere to glass,plastics and metals,these properties,coupled with the ability to control their hydrophilicity through monomer composition,lead to extensive its industrial application.
