Fa'atatauga

Polyvinylpyrrolidone o loʻo faʻaaogaina lautele i le matata o vailaʻau ma o se tasi lea o vailaʻau fou e tolu o loʻo fautuaina faʻavaomalo. O mea fa'apipi'i fa'aaoga lautele o papa ma granules. E mafai foʻi ona faʻaaogaina e fai ma fesoasoani faʻafefe mo capsules, faʻamaʻi ma lubricant mo vailaʻau mata, o se soli-solvent mo tui, o se faʻasalalau mo sauniuniga vai, ma se faʻamautu mo enzymes ma vailaʻau vevela. E mafai fo'i ona tu'ufa'atasia le povidone ma le iodine povidone iodine (PVP-I) fa'ama'i. I tioata fa'afeso'ota'i, e fa'aaogaina le PVP e fai ma vaega o tioata fa'afeso'ota'i e fa'ateleina ai lo latou hydrophilicity. E mafai foʻi ona faʻaaogaina le PVP e fai ma faʻasao cryogenic i vailaʻau.
