Kollidon® VA 64 is a white or slightly yellowish, free-flowing powder with a faint characteristic odour 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.
Benefits
• It provides erodible instant release matrix
• It is a solubiliser, dispersant, crystallization inhibitor and matrix former
• For direct compression, roller compaction and wet granulation, suitable for markets with higher humidity exposure
• It has excellent stability throughout the extrusion process
• A coarse powder provides a dust free handling, good flowability and faster extruder feeding
