Polyvinyl Pyrrolidone PVP

Ibisobanuro bigufi:

PVP (polyvinylpyrrolidone) ni polimeri ikonjesha amazi ya polymer izwi cyane kubera guhuza bidasanzwe, gukora firime, no gutuza ibintu. Hamwe na biocompatibilité nziza hamwe nuburozi buke, ikora nka cosmetike (umusatsi, umusatsi, shampo) ， ibintu byingenzi mubuvuzi bwa farumasi (ibinini bya tablet, capsule coatings, kwambara ibikomere), hamwe nibikorwa byinganda (wino, ububumbyi, ibikoresho byogeza). Ubushobozi bwayo buhanitse bwongera imbaraga zo gukemura no bioavailable ya APIs. Uburemere bwa PVP buringaniza (K-indangagaciro) butanga ibintu byoroshye guhinduka, bikagufasha kubona neza, gufatana, no kugenzura.
