Poly(1-vinylpyrrolidone-co-vinyl acetate) ndiye zinthu zazikulu zopangira zodzola zomwe zimagwiritsidwa ntchito popanga gel ya tsitsi, mousse, shampoo, ndi zina zotero, komanso ma surfactants, mankhwala ndi ntchito zina zamafakitale. Amagwiritsidwa ntchito makamaka ngati zomatira zosungunuka m'madzi ndi zomatira zouma mu granulation ndi direct tableting technology, ngati zinthu zopangira filimu mu flatting film, komanso ngati zinthu zopangira pores mu masking agents. PVP va64 imagwiritsidwa ntchito popanga shuga kuti isasweke. Chomatira cha pansi chimagwiritsidwa ntchito popanga chinyezi. PVP va copolymer mu zodzoladzola, Zogulitsa za Vp/va copolymer zimagwiritsidwa ntchito makamaka ngati zomatira zopangira filimu ndi zomatira m'munda wa zodzoladzola, makamaka mu zomatira zophulika, ma gels a tsitsi, mousse ndi shampoo series. Zimagwira ntchito yofunika kwambiri ngati zomatira zopangira filimu ndi zomatira zouma. Ngati zigwiritsidwa ntchito limodzi ndipvp k30, mphamvu yawo yogwiritsira ntchito idzawonjezeka.
