CAS 25086-89-9 Copovidone
Alias:VP/VA Copolymer60/40,Poly(1-vinylpyrrolidone-co-vinyl acetate)
Molecular Formula: (C6H9NO)n.(C4H6O2)m
In view of its excellent adhesiveness ,film hard and other properties,Copovidone is mainly used as water-soluble binder and dry binder in wet/direct granulation processes,also it can be used as film forming materials.
Covedone VA64 possesses excellent powder and film properties for broad application in the pharmaceutical field:
1.Water soluble tablet binder:suitable wet or dry granulation and direct compression processes,improves particle compressibility.
2.Film-former:permeable film coating for tablet and sugar coatings to protect against splitting,decrease moisture sensitivity and provide good film adhesiveness,elasticity and hardness.
3.Porogenic agent:for use in taste-masking and component of the matrix material used in controlled-release formulation.
4.Solubilizing agents:for solid depersion processes to enhancing bioavailability and improve drug solubility.
Acts as an excellent tablet binder aid in the direct compression tablet process. Increases tablet strength and reduces friability due to high compressibility and excellent adhesive properties.
