(HPMC) Phapano ke efe ka S kapa ntle le eona?

Ho bonahala u bua ka eonaHydroxypropyl Methylcellulose (HPMC), polymer e sebelisoang haholo liindastering tse fapaneng ho kenyeletsoa tsa meriana, kaho, lijo le litlolo. Phapano lipakeng tsa HPMC e nang le tlhaku 'S' kapa ntle le eona e kanna ea ama limaraka tse fapaneng, libopeho, kapa lihlahisoa tse ikhethileng.

Hydroxypropyl Methylcellulose (HPMC) ke semi-synthetic, inert, viscoelastic polymer e nkiloeng ho selulose. Hangata e hlahisoa ka phetoho ea lik'hemik'hale ea selulose, e kenyelletsang ho phekola cellulose ka alkali le propylene oxide ho hlahisa hydroxypropyl le lihlopha tsa methyl.

Lintlha tse ling tsa bohlokoa ka HPMC ke tsena:

Sebopeho sa Lik'hemik'hale: HPMC e na le liketane tse telele tsa likarolo tsa tsoekere tse nang le hydroxypropyl le lihlopha tsa methyl tse khomaretsoeng ho tse ling tsa lihlopha tsa hydroxyl (-OH). Karolelano ea likarolo tsena e ka fapana, e lebisang ho limaraka tse fapaneng tsa HPMC e nang le thepa e ikhethang.

Thepa ea 'Mele: HPMC e qhibiliha ka metsing 'me e etsa litharollo tse bonaletsang, tse mahlonoko ha e qhibiliha ka metsing. Viscosity ea eona e ka laoloa ka ho fetola likarolo tse kang boima ba molek'hule, tekanyo ea ho fetola le ho tsepamisa mohopolo.

Lisebelisoa:

Meriana ea Meriana: HPMC e atisa ho sebelisoa mefuteng ea meriana e le ntho e teteaneng, e kopanyang, ea pele ea filimi, le e tsoelang pele e lokolloa matlapeng, li-capsules, le li-topical formulations.
Kaho: Linthong tsa kaho tse kang lirafshoa, li-renders le li-adhesives tsa lithaele, HPMC e ntlafatsa ts'ebetso, ho boloka metsi le ho khomarela.
Lijo: HPMC e sebelisoa lihlahisoa tsa lijo e le setenya, se tsitsitseng, le emulsifier. Hangata e fumanoa lihlahisoa tsa lebese, li-sauces le li-dessert.
Litlolo: HPMC e kenyelelitsoe ho litlolo le lihlahisoa tsa tlhokomelo ea motho joalo ka litlolo, litlolo, le li-shampoo ho matlafatsa sebopeho, botsitso le thepa ea ho etsa lifilimi.

Melemo:

HPMC e fana ka thepa e ntle haholo ea ho boloka metsi, e leng ea bohlokoa bakeng sa lits'ebetso tse joalo ka seretse se thehiloeng ho samente moo ho hlokahalang metsi a nako e telele bakeng sa pheko e nepahetseng.
E ntlafatsa ho khomarela le ho sebetsa ka thepa ea kaho, ho kenya letsoho mosebetsing o betere le ho tšoarella.
Litlhare, HPMC e thusa ho lokolloa ha lithethefatsi tse laoloang le ho ntlafatsa thepa ea ho arohana ha letlapa.
HPMC e nkoa e bolokehile hore e ka sebelisoa 'me e amoheloa hohle lijong le lihlahisoa tsa litlolo.
Mephato le Litlhaloso: HPMC e fumaneha ka limaraka tse fapaneng le litlhaloso tse etselitsoeng lits'ebetso tse ikhethileng. Tsena li kenyelletsa phapang ea viscosity, boholo ba likaroloana, boemo ba ho fetola, le likarolo tse ling ho finyella litlhoko tsa liindasteri tse fapaneng le libopeho.

Maemo a Taolo: HPMC ka kakaretso e amoheloa e le e bolokehileng (GRAS) ke balaoli ba taolo joalo ka US Food and Drug Administration (FDA) ha e sebelisoa ho latela mekhoa e metle ea tlhahiso.

HPMC ke polymer e feto-fetohang e nang le lits'ebetso tse fapaneng ho pholletsa le liindasteri. Thepa ea eona e ka hlophisoa hore e finyelle litlhoko tse khethehileng, e etsa hore e be motsoako oa bohlokoa mefuteng e fapaneng ea lihlahisoa le lihlahisoa. Haeba u na le lintlha tse qaqileng haholoanyane mabapi le HPMC ka tlhaku 'S' kapa ntle le eona, ka kopo fana ka moelelo o eketsehileng bakeng sa tlhaloso e tobileng.
