Copovidone is a vinylpyrrolidone-vinyl acetate copolymer that is soluble both in water and in alcohols.
It is used in the pharmaceutical industry as binders, granulating agents, retarding agents and film, Forming agents in drugs.
Copovidone meets the requirements of the latest USP/NF, Ph.Eur. and JPE
White or slightly yellowish, free-flowing powder.
Odor and practically no taste.
Copovidone readily dissolves in all hydrophilic solvents. Solutions of more than 10 % concentration can be pre-pared in: water; ethanol; isopropanol; methylene chloride; glycerol; propylene glycol; it is less soluble in: ether; cyclic, aliphatic and alicyclic hydrocarbons.
Is an excellent binder for tablets and granules.
Between 2 % and 5 %, as a proportion of the final weight of the preparation, is usually used.
Forms films that are soluble at all Ph values.
Is used in sugar-coating to improve the adhesion of the coating to the surface of the tablet core and to increase the capacity of the coating solution for pigments and improve their dispersibility.
