KOLLIDON® VA 64
Copovidone USP/NF, EP, JPE Kollidon VA 64 grades are excellent dry binders. Basically they are vinylpyrrolidone - vinyl acetate copolymers which are soluble in both water and alcohols. It is white or slightly yellowish powder with a faint characteristic odour and practically no taste. An important property of Kollidon VA 64 is it’s plasticity which distinguishes it from Povidone (eg. Kollidon). This property often gives granules and mixtures that are less susceptible to capping during tabletting and results in tablets that are less brittle.
