I-PVP (i-Polyvinyl Pyrrolidone) – i-Cosmetic, i-Pharmaceutical & Industrial Grades amaBanga obunzima beMolekyuli akhoyo

I-Polyvinyl Pyrrolidone PVP

I-PVP (i-Polyvinyl Pyrrolidone) – I-Cosmetic, i-Pharmaceutical & Industrial Grades ye-Molecular Weight Grades efumanekayo

Inkcazelo emfutshane:

I-PVP (i-polyvinylpyrrolidone) yipolymer eyenziweyo enyibilikayo emanzini edume ngokubophelela okukhethekileyo, ukwenza ifilim, kunye neempawu zokuzinzisa. Nge-biocompatibility egqwesileyo kunye netyhefu ephantsi, isebenza njengezinto zokuthambisa (iinwele, iishampu), i-excipient ebaluleke kakhulu kumayeza (izibophelelo zethebhulethi, ii-capsules zokugquma, ukunxitywa kwamanxeba), kunye nokusetyenziswa kwemizi-mveliso (iinki, iiseramikhi, izicoci). Ubuchule bayo obuphezulu bokuntsonkotha buphucula ukunyibilika kunye ne-bioavailability yee-APIs. Ubunzima bemolekyuli obunokuguqulelwa bePVP (K-values) bubonelela ngokuguquguquka kuzo zonke iifomyula, ukuqinisekiswa kwe-viscosity efanelekileyo, ukunamathela, kunye nolawulo lokusasazwa.
