Copovidone ndi polima wosungunuka m'madzi womwe umagwiritsidwa ntchito kupititsa patsogolo katengedwe kake komanso kukweza mankhwala kwamankhwala osiyanasiyana, kuphatikiza zigamba zakulera.
Poly(1-vinylpyrrolidone-co-vinyl acetate) ndiye zida zazikulu zodzikongoletsera zomwe zimagwiritsidwa ntchito ngati gel osakaniza tsitsi, mousse, shampoo, ndi zina zambiri, komanso zowonjezera, mankhwala ndi ntchito zina zamafakitale. Amagwiritsidwa ntchito makamaka ngati zomatira zosungunuka m'madzi ndi zomatira zowuma muukadaulo wa granulation ndi ukadaulo wowongolera mapiritsi, monga zida zopangira filimu muzopaka filimu, komanso ngati pore kupanga zinthu mu masking agents. Amagwiritsidwa ntchito popaka shuga kuti apewe kusweka. Chophimba pansi pa chemicalbook chimagwiritsidwa ntchito pofuna kuteteza chinyezi. Zogulitsa za Vp/va copolymer zimagwiritsidwa ntchito makamaka ngati opanga mafilimu ndi makongoletsedwe pantchito ya zodzoladzola, makamaka pophulika, ma gels atsitsi, mousse ndi mankhwala a shampoo. Amagwira ntchito yofunikira ngati wothandizira opanga mafilimu komanso kukonza tsitsi. Ngati agwiritsidwa ntchito limodzi ndi pvpk30, zotsatira zake zimalimbikitsidwa.
Maonekedwe ndi ufa woyera kapena madzi opanda mtundu. Mtundu wokhazikika ndi PVP-64.
