Poly (1-vinylpyrrolidone-co-vinyl acetate) yog cov khoom siv tseem ceeb ntawm cov tshuaj pleev ib ce siv rau cov plaub hau gel, mousse, tshuaj zawv plaub hau, thiab lwm yam, nrog rau surfactants, tshuaj thiab lwm yam kev lag luam. Lawv feem ntau yog siv ua cov nplaum uas yaj tau hauv dej thiab cov nplaum qhuav hauv kev siv tshuab granulation thiab cov ntsiav tshuaj ncaj qha, ua cov ntaub ntawv tsim zaj duab xis hauv txheej zaj duab xis, thiab ua cov tshuaj tsim cov qhov hauv cov neeg sawv cev masking. PVP va64 yog siv rau txheej qab zib kom tiv thaiv kev tawg. Lub txheej hauv qab yog siv rau cov hom phiaj tiv thaiv dej noo. PVP va copolymer hauv cov tshuaj pleev ib ce, Vp / va copolymer series cov khoom feem ntau yog siv ua cov neeg sawv cev tsim zaj duab xis thiab cov neeg sawv cev styling hauv kev lag luam ntawm cov tshuaj pleev ib ce, tshwj xeeb tshaj yog hauv cov neeg sawv cev tawg, cov plaub hau gels, mousse thiab cov tshuaj zawv plaub hau series khoom. Lawv ua lub luag haujlwm tseem ceeb ua tus neeg sawv cev tsim zaj duab xis thiab tus neeg sawv cev styling plaub hau. Yog tias lawv siv ua ke nrogpvp k30, lawv cov txiaj ntsig siv yuav raug txhim kho.
