Application

Polyvinylpyrrolidone inoshandiswa zvakanyanya mumunda wemishonga uye ndeimwe yevatatu mitsva yemishonga yemishonga inotsigirwa pasi rose. Zvinyanya kushandiswa zvakanyanya mahwendefa nemagranules. Inogonawo kushandiswa seyamuro yekuyerera ye capsules, detoxification uye lubricant yemishonga yemaziso, co-solvent yejekiseni, dispersant yekugadzirira mvura, uye stabilizer ye enzymes uye kupisa-sensitive mishonga. Povidone inogona zvakare kugadzirwa neiyo iodine povidone iodine (PVP-I) mushonga wekuuraya utachiona. Mukuonana lenzi, PVP inoshandiswa sechikamu chekubatanidza lenzi kuwedzera hydrophilicity yavo. PVP inogonawo kushandiswa se cryogenic preservative mumishonga.
