Kollidon VA 64 Fine

Kollidon® VA 64 Fine is a white or slightly yellowish powder with a faint characteristic odor and practically no taste. It readily dissolves in all hydrophilic solvents. Solutions of more than 10 % concentration can be prepared in water, ethanol, isopropanol, methylene chloride, glycerol and propylene glycol. It is less soluble in ether, cyclic, aliphatic and alicyclic hydrocarbons. Kollidon VA 64 Fine is spray dried polymer powder of copolymer derived from the monomer N-vinylpyrrolidone (NVP) and vinyl acetate (VAc) with a weight ratio of approx 6:4. It is Suitable for increasing blend compressibility. Kollidon VA 64 Fine is a highly effective binder even at low concentrations for medium and high dose formulations. It has very good plasticity combined with fine particle size distribution produce very hard tablets. Another advantage is , it is amenable for processing and storage in all temperature zone markets
