| CAS No: | 25249-54-1 | |
| Product Type: | Organic Chemicals and Derivatives -> Hydrocarbons | |
| Product spec: | 10000 | |
| Packing: | ||
| Post Time: | 2018-04-23 | |
| Usage: | 1.Because of high molecular weight and crosslinking structure, PVPP can not dissolve in water but can quickly adhibit water and make its network structure expand and breakdown. So PVPP is widely used as disintegrating agent and bulking agent of troche, pelletized granule and capsule in pharmaceutical area. 2.And the molecule has amido bond and adsorb hydroxyl of polyphenol molecule to form hydrogen bond, therefore it can uses as stabilizer of beer, ratafee and potable spirit, prolong the quality guarantee duration to 300 days, and also can improve the transparence, color and taste. | |
| Description: | Product Name: PVPP Synonyms: Crospovidone CAS No.: 25249-54-1 EINECS: *** Molecular Formula: (C6H9NO)n Molecular Weight: *** Physical properties: White or creamy white powder with faint characteristic odor, which is easily hyhilic and capable of complex with such substance as phenol, etc. It is completely insoluble with relatively high crosslink density and does not form gels that can impede disintegration, dissolution and drug release.
