Applications,
As solubilizer, it is suitable for oral and parenteral preparations, can improve the solubility of poorly soluble drugs in solid dispersions. It is also used as dispersant or crystallization inhibitor in liquid formulations.
As Binder, It is suitable for wet granulation and dry granulation, and is directly pressed in the tabletting process, which improves the compressibility of the granules. It can be added in dry or granular form by adding water, alcohol or water-alcohol solution Powder mixture. It also used as film-forming agent, solubilizer, suspension stabilizer, and dispersant in solid and liquid preparations.
Used as binder, thickener and suspension stabilizer in formulations.
Package: 25kg/drum
