IHydroxypropyl Methylcellulose (HPMC)
Incazelo Yemikhiqizo
IHydroxypropyl Methylcellulose (HPMC) isebenza ngezindlela eziningi njengesithambiso, isithuthukisi segwebu nokuqiniswa, ukuqina, i-emulsion stabilizer kanye nefilimu yangaphambili yemikhiqizo yokunakekelwa kwezinwele nesikhumba.
Izinzuzo
I-HPMC ilusizo ikakhulukazi ezinhlelweni ze-surfactant yezakhiwo zayo ezithuthukisa igwebu, isiza ekwakhekeni kwesakhiwo sebhamuza, okuholela ekucebeni okucebile, okuhlala isikhathi eside. I-HPMC inokubekezelela okuphezulu kokubili usawoti kanye notshwala.
Isicelo
- I-Shampoo: thuthukisa i-viscosity yama-shampoos, okokuhlanza, nezinto zokuhlanza kanye nokuzinza kwamabhamuza.
- I-toothpaste: thuthukisa i-fluidity ye-toothpaste.
Formulation Guide
- Indlela ekhethwayo iwukuqala ngokushisisa cishe u-1/3 wesamba samanzi okwakheka ku-167°F (75°C) noma ngaphezulu. Engeza i-HPMC ku-vortex yamanzi anyakazayo nashisayo. Hlanganisa kuze kuhlakazwe ngokuphelele. I-HMPC ngeke incibilike kuleli zinga lokushisa. Ngemva kokuhlakazwa okuphelele, engeza amanzi asele ekamelweni lokushisa noma elibandayo futhi uqhubeke uxuba imizuzu engu-30 ngemva kokuba isamba sesixazululo sesipholise ku-77°F. (25°C) noma ngaphansi. Qhubeka nokwakhiwa.
- Uma ukushisisa kungenzeki, kunconyelwa ukucwilisa i-HPMC kumidiya engaxazululi, njenge-glycerin noma i-PEG, bese wengeza udaka ku-vortex yamanzi anyakaziswa ngamandla. Ukwengeza i-HPMC ngqo emanzini abandayo akukhethwa, kodwa uma kunesidingo, kufanele kwenziwe kancane kakhulu ngaphansi kokuyaluza okunamandla. Lindela izikhathi ezinde zokuhlanganisa ukuze ziqedwe ngokuphelele.
