I-Copovidone iyi-polymer encibilika emanzini esetshenziselwa ukuthuthukisa ukumuncwa kanye nokulayishwa kwezidakamizwa kwama-ejenti ahlukahlukene emithi, okuhlanganisa neziqephu zokuvimbela inzalo.
I-Poly(1-vinylpyrrolidone-co-vinyl acetate) iyimpahla eyinhloko yezimonyo esetshenziselwa ijeli yezinwele, i-mousse, i-shampoo, njll., kanye nama-surfactants, imithi kanye nezinye izinjongo zezimboni. Zisetshenziswa kakhulu njengama-adhesives ancibilika emanzini kanye nezinamatheliso ezomile ku-granulation kanye nobuchwepheshe bethebhulethi obuqondile, njengezinto zokwakha ifilimu ekuhlanganisweni kwefilimu, nanjengezinto ezenza izimbotshana kuma-masking agents. Isetshenziselwa ukugcoba ushukela ukuvimbela ukuqhekeka. I-chemicalbook coating isetshenziselwa izinjongo zokuvikela umswakama. Imikhiqizo yochungechunge lwe-Vp/va copolymer isetshenziswa ikakhulukazi njengama-ejenti abenza amafilimu nama-ejenti esitayela emkhakheni wezimonyo, ikakhulukazi kuma-ejenti aqhumayo, amajeli ezinwele, ama-mousse nemikhiqizo yochungechunge lwe-shampoo. Badlala indima ebalulekile njenge-ejenti yokwenza ifilimu kanye ne-ejenti yokwenza izinwele. Uma zisetshenziswa kanye ne-pvpk30, umphumela wazo wokusebenzisa uzothuthukiswa.
Ukubukeka kuyimpushana emhlophe noma uketshezi olungenambala. Uhlobo olujwayelekile yi-PVP-64.
