Iholeyili Povidone-K90 / PVP-K90
Intshayelelo:
| INCI | Imolekyuli |
| I-POVIDONE-K90 | ( C6H9NO )n |
I-Povidone (i-polyvinylpyrrolidone, i-PVP) isetyenziswa kwishishini lamachiza njengesithuthi sepolymer eyenziweyo yokusabalalisa kunye nokumisa iziyobisi.Inokusetyenziswa ngeendlela ezininzi, kubandakanywa njenge-binder yeepilisi kunye ne-capsules, ifilimu yangaphambili yezisombululo ze-ophthalmic, ukuncedisa kwi-flavoring liquids kunye neepilisi ezihlafunwayo, kunye ne-adhesive for transdermal systems.
I-Povidone ine-formula ye-molecular (C6H9NO) n kwaye ibonakala imhlophe ukuya kumgubo omhlophe omhlophe.I-Povidone formulations isetyenziswa ngokubanzi kwishishini lamachiza ngenxa yokukwazi ukunyibilika kumanzi kunye ne-oil solvents.Inani elingu-k libhekisa kubunzima bemolekyuli yepovidone.Iipovidone ezinamaxabiso aphezulu e-K (okt, k90) aziqhelekanga ukunikwa ngesitofu ngenxa yobunzima bazo obuphezulu bemolekyuli.Ubunzima beemolekyuli eziphezulu zithintela ukukhutshelwa zizintso kwaye zikhokelela ekuqokeleleni emzimbeni.Umzekelo owaziwa kakhulu wokuqulunqwa kwe-povidone yi-povidone-iodine, isibulala-ntsholongwane esibalulekileyo.
Ukuqukuqela kwasimahla,umgubo omhlophe,uzinzo olulungileyo,ukungacaphuki,ukunyibilika emanzini kunye ne-ethnol,ikhuselekilekwaye kulula ukuyisebenzisa,.Iyasebenza ekubulaleni i-bacillus,intsholongwane kunye ne-epiphytes.Ihambelana nobuninzi bomphezulu.
Ikho njengokuqukuqela okukhululekileyo, umgubo obomvu obomvu, ongacaphukiyo kwaye uzinzo oluhle, inyibilika emanzini nasetywaleni, enganyibilikiyo kwi-diethylethe kunye ne-chloroform.

Ugcino
Iminyaka emibini ukuba igcinwe phantsi kweemeko ezipholileyo nezomileyo kunye nesikhongozeli esivaleke kakuhle
I-Polyvinylpyrrolidone ngokuqhelekileyo ikwimo yomgubo okanye isisombululo ikhona.I-PVP kwi-cosmetics mousse, i-eruption, kunye neenwele, ipeyinti, inki yokushicilela, i-textile, ukuprinta kunye nokudaya, iityhubhu zemifanekiso yombala zingasetyenziswa njengeejenti zokugubungela umphezulu, i-agent echithachithayo, i-thickeners, i-binders.Kwiyeza zezona zibophelelayo zisetyenziswa kakhulu kwiipilisi, iigranules kunye nokunye.
