Hydroxypropyl methylcellulose (HPMC) ke polymer e feto-fetohang e nkiloeng ho cellulose, polysaccharide ea tlhaho e fumanehang maboteng a lisele tsa limela. E sebelisoa hangata liindastering tse fapaneng tse kang tsa meriana, lijo, litlolo, kaho le tse ling ka lebaka la thepa ea eona e ikhethang.
HPMC e entsoe ka ho fetola selulose ka lik'hemik'hale ka karabelo ea etherification. Haholo-holo, e hlahisoa ka ho phekola cellulose ka motsoako oa propylene oxide le methyl chloride ho hlahisa lihlopha tsa hydroxypropyl le methyl mokokotlong oa cellulose. Ts'ebetso ena e fella ka polima e qhibilihang ka metsing e nang le thepa e ntlafalitsoeng ha e bapisoa le selulose ea matsoalloa.
Mokhoa oa Tlhahiso:
Tlhahiso ea HPMC e kenyelletsa mehato e mengata:
Cellulose Sourcing: Cellulose, eo hangata e nkiloeng ho tloha lehong la lehong kapa k'hothone, e sebetsa e le lisebelisoa tsa ho qala.
Etherification: Cellulose e kena etherification, moo e sebetsanang le propylene oxide le methyl chloride tlas'a maemo a laoloang ho hlahisa hydroxypropyl le lihlopha tsa methyl.
Tlhoekiso: Sehlahisoa se hlahisoang se kena mehatong ea tlhoekiso ho tlosa litšila le lihlahisoa tse sa batleheng.
Ho omisa le ho Tula: HPMC e hloekisitsoeng e ntan'o omisoa ebe e siloa ka phofo e ntle kapa granules, ho itšetlehile ka kopo e lakatsehang.
HPMC e bonts'a mefuta e mengata ea thepa, e etsa hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng:
Ho qhibiliha ha Metsi: HPMC e qhibiliha ka metsing a batang, e etsa litharollo tse hlakileng, tse hlakileng. The solubility e ka fetoloa ka ho fetola tekanyo ea substitution (DS) ea hydroxypropyl le lihlopha tsa methyl.
Ho Etsa Lifilimi: E ka etsa lifilimi tse feto-fetohang le tse momahaneng ha li omisitsoe, tsa etsa hore e tšoanelehe bakeng sa likopo tsa ho roala liindasteri tsa meriana le tsa lijo.
Thickening: HPMC ke e atlehang thickening moemeli, fana ka taolo ya viscosity ka formulations tse fapa-fapaneng tse kang lotions, litlolo, le lipente.
Botsitso: E bonts'a botsitso bo botle ba lik'hemik'hale le ho hanyetsa ho senyeha ha likokoana-hloko.
Tšebelisano: HPMC e lumellana le mefuta e mengata e fapaneng ea metsoako, ho kenyelletsa le li-surfactants, matsoai le li-preservatives.
HPMC e fumana lits'ebetso tse ngata ho pholletsa le liindasteri tse fapaneng:
Meriana ea Meriana: Hangata e sebelisoa e le se tlamellang, se koahelang filimi, se feto-fetohang sa viscosity, le matrix e tsitsitseng e sa khaotseng ho etsoa ha matlapa.
Indasteri ea Lijo: HPMC e sebetsa e le setei, se tsitsitseng, le emulsifier lihlahisoa tsa lijo tse kang li-sauces, li-dressings le li-dessert.
Kaho: Lefapheng la kaho, HPMC e sebelisoa e le motenya lihlahisoa tse thehiloeng ho samente, ho ntlafatsa ts'ebetso le ho khomarela.
Lihlahisoa tsa Tlhokomelo ea Motho: E fumanoa ka litlolo, li-shampoo, le sesepa sa meno e le ntho e matlafatsang, emulsifier le filimi ea pele.
Lipente le Liaparo: HPMC e ntlafatsa thepa ea rheological ea lipente le liphahlo, e ntlafatsa ts'ebeliso le ts'ebetso ea tsona.
HPMC, e nkiloeng ho selulose ka karabelo ea etherification, ke polima e feto-fetohang e nang le lits'ebetso tse fapaneng liindastering tse fapaneng. Mehaho ea eona e ikhethang, joalo ka ho qhibiliha ha metsi, bokhoni ba ho etsa lifilimi, le thepa ea eona e teteaneng, e etsa hore e be ea bohlokoa haholo ho tsa meriana, lijo, kaho le lihlahisoa tsa tlhokomelo ea motho.
