Poly(1-vinylpyrrolidone-co-vinyl acetate) waa agabka ugu muhiimsan ee qurxinta qurxinta waxaana loo isticmaalaa jelka timaha, mousse, shaambo, iwm., iyo sidoo kale surfactants, daawooyinka iyo ujeedooyin kale oo warshadeed. Waxaa inta badan loo isticmaalaa sida dhejisyo biyaha ku milma iyo dhejisyo qalalan oo ku jira granulation iyo tiknoolajiyada kiniiniyada tooska ah, sida walxaha sameeya filimada ee dahaarka filimka, iyo sida walxaha sameeya daloolada ee wakiilada maaskaro. PVP va64 waxaa loo isticmaalaa dahaarka sonkorta si looga hortago dildilaaca. Dahaarka hoose waxaa loo isticmaalaa ujeedooyin qoyaan u adkaysta. PVP va copolymer ee qurxinta, alaabada taxanaha Vp/va copolymer waxaa inta badan loo isticmaalaa wakiillo sameeya filimada iyo wakiillo qaabeynta ee goobta qurxinta, gaar ahaan wakiilada qarxa, jelka timaha, mousse iyo alaabada taxanaha shaambo. Waxay door muhiim ah ka ciyaaraan wakiilka sameynta filimada iyo wakiilka qaabeynta timaha. Haddii lala isticmaalopvp k30, saameyntooda isticmaalku way sii fiicnaan doontaa.
