Fa'asologa o le Polyvinylpyrrolidone PVP PVP K12 K15 K17 K25 K30 K60 K90
E pei o le pauta po'o le vai, e mafai ona solo i le vai, 'ava malosi, amine ma halogenated hydrocarbons, e le mafai ona solo i le acetone, ether, ma isi mea. E sili ona lelei lona solubility, biocompatibility, physiological inertness, physiological forming, membrane protection ability ma le mafai ona tu'ufa'atasia le tele o organic ma inorganic compounds. E mautu i le acid, masima ma le vevela, o lea e tele ai ona fa'aoga.

O le Polyvinylpyrrolidone e faʻaaogaina lautele i le matāgaluega o vailaʻau ma o se tasi o mea faʻaopoopo fou e tolu o vailaʻau e lagolagoina faʻavaomalo. O mea faʻapipiʻi e sili ona faʻaaogaina o papa ma granules. E mafai foʻi ona faʻaaogaina o se fesoasoani i le tafe o capsules, faʻamamāina o mea ma faʻasusu mo vailaʻau mata, o se co-solvent mo tui, o se dispersant mo sauniuniga vai, ma se stabilizer mo enzymes ma vailaʻau e maaleale i le vevela. E mafai foʻi ona faʻapipiʻiina le Povidone ma le iodine povidone iodine (PVP-I) disinfectant. I tioata faʻafesoʻotaʻi, e faʻaaogaina le PVP o se vaega o tioata faʻafesoʻotaʻi e faʻateleina ai lo latou hydrophilicity. E mafai foʻi ona faʻaaogaina le PVP o se mea e puipuia ai le cryogenic i vailaʻau.
