I-Copovidone i-polymer e-soluble yamanzi esetyenziselwa ukuphucula ukunyuswa kunye nokulayishwa kweziyobisi kwii-agent ezahlukeneyo zamachiza, kubandakanywa neepatches zokukhulelwa.
I-Poly (1-vinylpyrrolidone-co-vinyl acetate) yeyona nto iphambili yezinto zokuthambisa isetyenziselwa ijeli yeenwele, i-mousse, ishampu, njl., kunye ne-surfactants, amayeza kunye nezinye iinjongo zoshishino. Zisetyenziswa ikakhulu njengezinto zokuncamathelisa ezinyibilikayo emanzini kunye nezokuncamathelisa ezomileyo kwigranulation kunye nethekhnoloji yetheyibhile ngokuthe ngqo, njengezinto zokwenza ifilimu ekugqunyweni kwefilimu, nanjengezinto zokwenza iipore kwiiarhente zokufihla. Isetyenziselwa ukugquma iswekile ukuthintela ukuqhekeka. Ukugquma kwe-chemicalbook phantsi kusetyenziselwa iinjongo zobungqina bokufuma. Iimveliso ze-Vp/va copolymer series zisetyenziswa ikakhulu njengee-agent-film-forming agents kunye ne-styling agents kwi-cosmetics, ingakumbi kwi-erupting agents, iigels zeenwele, i-mousse kunye neemveliso ze-shampoo series. Badlala indima ebalulekileyo njenge-ejenti yokwenza ifilimu kunye ne-agent yesitayela seenwele. Ukuba zisetyenziswa kunye ne-pvpk30, umphumo wokusetyenziswa kwazo uya kwandiswa.
Imbonakalo ngumgubo omhlophe okanye ulwelo olungenambala. Uhlobo oluqhelekileyo luyi-PVP-64.
