Copovidone kua

CTFA Name: PVP/VA
CAS Nr.: 25086-89-9
Molecular Formula: (C₆H₉TSIS MUAJ)_n(C₄H₆TSIS MUAJ₂)_m

Daim ntawv thov:Clarifiers, stabilizers, thiab adsorbers siv hauv kev tsim cov txiv hmab txiv ntoo haus thiab npias. Dissolve enhancers thiab super-disintegrants los txhim kho cov khoom tso tawm ntawm cov ntsiav tshuaj, tshuaj ntsiav, thiab granules. remarkably ceev tso tawm ntawm active compounds nyob rau hauv cov ntaub ntawv koob tshuaj uas muaj zog. Txhim kho qhov tshwj xeeb hardly soluble active compounds 'bioavailability.

Khoom Txheem:USP, EP, CP; nws ua raws li kev lag luam, zaub mov-qib, thiab cov qauv tshuaj.
Cia:khaws cia qhuav, txias, thiab nyob rau hauv ib qho chaw ntxoov ntxoo

HLB thiab solubility zoo sib xws, nrog vinyl acetate pab txhawb ntau dua 50% rau cov copolymer, nce solubility hauv hydrophobic cov kuab tshuaj thiab txo qis hauv dej. VP / VA37 tsuas yog dej-insoluble copolymer, siv los ua cov ntawv nplaum adjuvant lossis dispersion hauv dej-thiab-roj tshuab. Lwm cov copolymer, zoo li VP / VA37, tuaj yeem siv rau hauv cov roj-hauv-dej emulsions thiab dej-raws li formulations. Txhawm rau txhim kho kev ruaj ntseg, dej-thiab-roj theem 'qhov nro tuaj yeem txo qis. Cov dej-soluble VP VA copolymer tuaj yeem txo qhov kev sib tshuam ntawm cov dej thiab Aromatic 150 ntawm cov concentrations tsawg li 0.1%.
