Copovidone yog ib qho dej-soluble polymer siv los txhim kho kev noj tshuaj thiab kev thauj khoom ntawm ntau yam tshuaj, suav nrog cov tshuaj tiv thaiv kab mob.
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 cov tshuaj surfactants, tshuaj thiab lwm yam lag luam. Lawv feem ntau yog siv los ua dej-soluble adhesives thiab qhuav adhesives nyob rau hauv granulation thiab direct tabletting technology, raws li film-forming cov ntaub ntawv nyob rau hauv zaj duab xis txheej, thiab raws li pore forming tshuaj nyob rau hauv daim npog qhov ncauj. Nws yog siv rau cov qab zib txheej los tiv thaiv kev tawg. Cov chemicalbook hauv qab txheej yog siv los ua kom tsis muaj dej noo. Vp / va copolymer series cov khoom lag luam feem ntau yog siv los ua cov neeg ua yeeb yaj kiab thiab cov styling cov neeg ua haujlwm hauv cov tshuaj pleev ib ce, tshwj xeeb tshaj yog cov tshuaj tua kab mob, cov plaub hau gels, mousse thiab tshuaj zawv plaub hau series. Lawv ua lub luag haujlwm tseem ceeb ua tus neeg sawv cev ua yeeb yaj kiab thiab tus neeg saib xyuas plaub hau. Yog tias lawv tau siv ua ke nrog pvpk30, lawv cov nyhuv siv yuav raug txhim kho.
Cov tsos mob yog cov hmoov dawb los yog kua tsis muaj xim. Hom niaj zaus yog PVP-64.
