Copovidone ipolymer inonyungudika mumvura inoshandiswa kuvandudza kutora uye kurodha zvinodhaka zveakasiyana emishonga, kusanganisira zvigamba zvekudzivirira kubata pamuviri.
Poly (1-vinylpyrrolidone-co-vinyl acetate) ndiyo huru zvishongedzo zvezvizorwa zvinoshandiswa kune bvudzi gel, mousse, shampoo, nezvimwewo, pamwe chete nevano surfactants, mishonga uye zvimwe zvinangwa zveindasitiri. Iwo anonyanya kushandiswa semvura-inonyungudika adhesives uye yakaoma adhesives mune granulation uye yakananga tabletting tekinoroji, semafirimu-ekugadzira zvinhu mufirimu coating, uye sepore inogadzira zvinhu mu masking agents. Inoshandiswa pakuputira shuga kudzivirira kuputika. Iyo chemicalbook yepasi yekuputira inoshandiswa kune hunyoro-uchapupu zvinangwa. Vp/va copolymer series zvigadzirwa zvinonyanya kushandiswa semafirimu-ekugadzira vamiririri uye styling vamiririri mumunda wezvizoro, kunyanya muanoputika maajenti, gel vhudzi, mousse uye shampoo series zvigadzirwa. Ivo vanoita basa rakakosha semugadziri wemufirimu-mugadziri uye bvudzi styling agent. Kana vakashandiswa pamwe chete nepvpk30, maitiro avo ekushandisa anowedzerwa.
Chitarisiko chichena hupfu kana mvura isina ruvara. Rudzi rwenguva dzose PVP-64.
