(HPMC) Uyini umehluko nge noma ngaphandle s?

Kubukeka sengathi ubhekisa kuI-Hydroxypropyl methylcellulose (HPMC), i-polymer esetshenziswe kabanzi emikhakheni ehlukahlukene kufaka phakathi amakhemisi, ukwakhiwa, ukudla kanye nezimonyo. Umehluko phakathi kwe-HPMC futhi ngaphandle kwencwadi 'kungenzeka uqinisekise amamaki ahlukene, ukwakheka, noma imikhiqizo ethile.

I-Hydroxypropyl Methylcellulose (HPMC) yi-semi-zokwenziwa, inert, i-viscoelastic polymer etholakala ku-cellulose. Ngokuvamile kukhiqizwa ngokuguqulwa kwamakhemikhali kwe-cellulose, okubandakanya ukwelapha i-cellulose nge-alkali kanye ne-propelene oxide ukwethula ama-hydroxypropyll kanye namaqembu we-methyl.

Nawa amanye amaphuzu asemqoka nge-HPMC:

Isakhiwo samakhemikhali: I-HPMC inamaketanga amade ama-glucose amayunithi nge-hydroxypropyl kanye namaqembu we-methyls anamaqembu anamaqembu athile we-hydroxyl (-OH). Isilinganiso salokhu kufakazelwa kwalokhu kungahlukahluka, okuholela kumabanga ahlukene we-HPMC anezinto ezihlukile.

Izakhiwo ezibonakalayo: I-HPMC ingamanzi ancibilikisiwe futhi amafomu asobala, izixazululo ezibonakalayo lapho echithwa emanzini. I-viscosity yayo ingalawulwa ngokulungiswa kwamapharamitha anjengesisindo se-molecular, degree of inqumetha, kanye nokuhlushwa.

Izicelo:

I-Pharmaceuticals: I-HPMC ivame ukusetshenziswa ekwakhiweni kwemithi njengoMkhulu, i-Binder, i-ejenti yangaphambili yefilimu, ne-ejenti yokukhishwa kwezibhebhe, kanye nokwakhiwa kwezindawo eziqhubekayo.
Ukwakha: Ezintweni zokwakha ezinjengezidakamizwa, kanye nama-tile anamathela, i-HPMC ithuthukisa ukusebenzi, ukugcinwa kwamanzi, nokunamathela.
Ukudla: I-HPMC isetshenziswa emikhiqizweni yokudla njengomuntu omkhulu, i-stabilizer, kanye ne-emulsifier. Imvamisa kutholakala kwimikhiqizo yobisi, amasoso, kanye nama-dessert.
I-COSMETICS: I-HPMC ifakiwe kwizimonyo kanye nemikhiqizo yokunakekelwa komuntu siqu njengama-okhilimu, i-lotions, nama-shampoos ukuthuthukisa ukuthungwa, ukuqina kanye nezakhiwo ezenziwe ngefilimu.

Izinzuzo:

I-HPMC ifaka izakhiwo ezinhle kakhulu zokugcina amanzi, okubaluleke kakhulu ngezinhlelo ezifana nodaka olususelwa kuso usimende lapho kudingeka khona i-hydration isikhathi eside ukuze uphule kahle.
Kuthuthukisa ukunamathela nokusebenza kwezinto zokwakha, kufaka isandla ekusebenzeni kangcono nokuqina.
Emikhakheni, i-HPMC isiza ukukhishwa kwezidakamizwa okulawulwayo kanye nokwenza ngcono izakhiwo zethebhulethi zethebhulethi.
I-HPMC ibhekwa njengephephile ukuze isetshenziswe futhi yamukelwa kabanzi emikhiqizweni yokudla kanye neyokudla.
Amabanga kanye nokucaciswa: I-HPMC iyatholakala kumabanga ahlukahlukene kanye nokucaciswa okuhambisana nezinhlelo ezithile. Lokhu kufaka phakathi umehluko ekuvulekezweni, usayizi wezinhlayiyana, izinga lokuthatha indawo, kanye namanye amapharamitha ukuze ahlangabezane nezidingo zezimboni ezahlukahlukene kanye nokwakheka.

Isimo Sokulawula: I-HPMC ngokuvamile ibonwa njengephephile (GRAS) ngeziphathimandla ezilawulayo ezifana ne-US Food and Drug Administration (FDA) lapho isetshenziswa ngokuya ngezindlela ezinhle zokukhiqiza.

I-HPMC iyi-polymer eguquguqukayo enezicelo ezahlukahlukene kuyo yonke imboni. Izakhiwo zayo zingalinganiswa ukuze zihlangabezane nezidingo ezithile, zilenze isithako esibalulekile ekunikezelweni okuhlukahlukene nemikhiqizo. Uma unemininingwane ethile eqondile maqondana ne-HPMC enobhalwe noma ngaphandle kwencwadi ', sicela unikeze ngomongo owengeziwe wencazelo ebhekiswe kakhudlwana.
