Incazelo:I-Hydroxypropylylylylylylylyllllule iyinhlangano ye-plylobal ether ye-methylcellose lapho zombili ama-hydroxypropyl kanye namaqembu we-methyl eboshelwe indandatho ye-glucose ye-anhydros ye-cellulose ngokuxhumana kwe-ether. I-Hydroxypropyllylylylylylyllllulose ihlelwe kusuka ku-methyl celtule ngesinyathelo se-alkali ne-propelene oxide. Umphumela wemiphumela uwukusulwa kwamanzi okususelwa e-cellulose equkethe amaqembu womabili ama-methoxy ne-hydroxypropylyl. Izinga lokufakwa esikhundleni ngu-1.08 lize libe ngu-1.83 ngamaqembu we-hydroxypropyl njengendawo encane. Mhlophe kuya ku-powder emhlophe emhlophe noma emigqeni. Incibilika emanzini nakwezinye izimo ze-organic. I-insoluble e-ethanol, ikhambi elinamanzi linomsebenzi ongaphezulu, lakha ifilimu elincanyana ngemuva kokoma, futhi lithola ushintsho oluguqukayo kusuka ku-sol to gel ukuvula nokupholisa.
Sebenzisa:I-Hydroxypropyllkylyly i-gum eyakhiwa ukusabela kwe-propylene oxide kanye ne-methyl chloride nge-alkali cellulose. Izokwanda kwe-gel njengoba izinga lokushisa lenyuka ngokushisa nangokupholisa kuzolidla. Izinga lokushisa le-gel lisukela kusuka ku-60 ° C kuya ku-90 ° C, kwakha ama-meshy ama-mushy. Isetshenziswa ezimpahleni zokubhaka, ukugqoka, ukudla okubhakelwe phansi, kanye nesaladi yokugqoka ukuxuba ukulawulwa kwe-pernesis, ukuthungwa, nokuhlinzeka nge-viscosity eshisayo. Izinga Lokusetshenziswa Kwezinga kusuka ku-0.05 kuya ku-1.0%.
Izinkomba:I-Hydroxypropyll methylcellulose ingeqembu lemithi eyaziwa ngokuthi izinyembezi zokufakelwa. Kusetshenziselwa ukudambisa ukoma nokucasuka okubangelwa ukugeleza okuncishisiwe kwezinyembezi. Kuyasiza ukuvikela ukulimala kwamehlo ezifweni ezithile zamehlo. I-Hydroxypropylylylylylylys i-methylcellulose nayo ingahle isetshenziselwe ukugcoba amalensi okuxhumana kanzima kanye namehlo okufakelwa. Ngaphezu kwalokho, ingahle isetshenziswe ekuhlolweni kwamehlo ezithile.
Isingeniso Esinemininingwane
I-Hydroxypropyl methyl cellulose (HPMC)Ingabe okususelwa kwe-cellulose, okuyi-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. I-HPMC ikhiqizwa ngenqubo yokuguqulwa kwamakhemikhali ehilela ukwelapha iselula nge-propelene oxide ne-methyl chloride.
I-HPMC iyimpuphu emhlophe, engenamophu enyakazisa emanzini futhi yakha ijeli ecacile, ebonakalayo lapho ichithwa. Inezinhlobonhlobo zezicelo kuzo zonke izimboni ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile.
Nazi ezinye izici ezibalulekile ze-HPMC:
Umenzeli wokuqina:I-HPMC iyisidina esisebenza kahle kakhulu kanye ne-viscosity modifier. Kungakhuphula kakhulu ukubonakala koketshezi, okwenza kube lusizo ezinhlobonhlobo zemikhiqizo edinga ukungaguquguquki okuminyene noma kwe-gel-efana.
Izakhiwo ezenziwe ngefilimu:I-HPMC ingakha ifilimu elincanyana, eliguquguqukayo lapho isetshenziswa ezindaweni ezikhona. Le mpahla ivame ukusetshenziselwa ukugqoka, upende, kanye nezinye izinhlelo ezidinga ungqimba oluvikelayo noma oluvimbayo.
Ukugcinwa kwamanzi:I-HPMC inezakhiwo ezinhle kakhulu zokugcina amanzi, ukuvumela ukugcina umswakama ekwakhiweni. Lokhu kwenza kube lusizo kuzinhlelo zokusebenza ezifana nezinto zokwenziwa komoya, lapho kungathuthukisa ukusebenza futhi kunciphise ukushwabana.
I-Emulsion Statizer:I-HPMC ingazinza ama-emulsions, ivimbela ukuhlukaniswa kwezigaba zamafutha nezitha zamanzi. Isetshenziswa kakhulu kwizimonyo kanye nemikhiqizo yokunakekelwa komuntu siqu ukuze ulondoloze ukuqina nokuvumelana kokhilimu, ama-lotion kanye nezinye izinyanga.
Izakhiwo ezilawulwa ezilawulwayo:I-HPMC ingalawula ukukhishwa kwezithako ezisebenzayo, ikakhulukazi embonini yezemithi. Kungakha i-matrix ye-gel ebambezela ukukhishwa kwezidakamizwa, ukuhlinzeka ukukhishwa okulawulwayo nokuqhubekayo ngokuhamba kwesikhathi.
Okungabi nanobuthi futhi kube nobungane bemvelo:I-HPMC ibhekwa njengephephile ukuze isetshenziswe kwizicelo ezahlukahlukene. Akulona ubuthi, i-biodegradable, futhi ayibangeli ingozi yezempilo yabantu noma imvelo.
Sekukonke, i-HPMC isithako esiguquguqukayo futhi esisetshenziswa kabanzi ezimbonini ezinjengezemithi, ukwakhiwa, ukudla, ukunakekelwa komuntu siqu, upende kanye nezolimo. Amandla alo okuguqula i-viscosity, gcina umswakama, ukuqina kokuqina, ukukhishwa kokulawula kwenza kube yisengezo esibalulekile ngezicelo ezahlukahlukene.
Isicelo
I-Hydroxypropylylylylyl methyl cellulose (HPMC) yi-hydrocollopp etholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. I-HPMC isetshenziswa kakhulu ezinhlobonhlobo zezimboni ngenxa yezakhiwo zayo ezihlukile.
Nazi ezinye izinhlelo ezijwayelekile ze-HPMC:
Imboni Yezemithi: I-HPMC isetshenziswa kabanzi embonini yezemithi njenge-excipietical yekhamishini. Isetshenziswa ekusungulweni kwethebulethi njenge-binder, filler, nokuqhekeka. I-HPMC ingathuthukisa ukuchithwa kanye nokuvuselelwa kwezidakamizwa ngenkathi ihlinzeka ngezakhiwo zokukhishwa ezilawulwayo.
Imboni Yokwakha: I-HPMC isetshenziswa kakhulu embonini yezokwakha njenge-Swerener, i-ejenti yokugcina amanzi, kanye ne-binder. Ingezwa emikhiqizweni esekwe kuthusi efana nama-tile anamathela, ama-grouts, udaka, nodaka ukuze athuthukise ukusebenziseka, ukugcinwa kwamanzi, nokunamathela.
Imboni yokudla:I-HPMC isetshenziswa njengesengezo embonini yokudla lapho isebenza khona njengesikhulu, i-Stabilizer, kanye ne-emulsifier. Isetshenziswa kwimikhiqizo efana nokugqoka kwesaladi, amasoso, ukugcwaliswa kwebhayidi, kanye no-ayisikhilimu ukwenza ngcono ukuthungwa, ukubonakala nokuqina.
Imikhiqizo Yokunakekelwa Kwakho:I-HPMC isetshenziswa emikhiqizweni yokunakekelwa komuntu siqu efana nokhilimu, ama-lotions kanye nama-shampoos njengomguquguquki omkhulu kanye ne-viscosity. Inikeza ukuvumelana okubushelelezi nokunokhilimu kwale mikhiqizo futhi kuthuthukisa ukuqina kwabo.
Amapende nezimbobo:I-HPMC yengezwa kupende osuselwa emanzini kanye nezingubo zokugqoka ukuze zithuthukise ukushuba kwazo, zivikele ukugcwala, futhi zithuthukise akesion. Isebenza njenge-stabilizer futhi ingathuthukisa izakhiwo zokugeleza kanye nezinga lokupenda ngopende.
Imboni Yezolimo:I-HPMC isetshenziswa kwizicelo zezolimo njenge-persener kanye ne-ejenti eyakha amafilimu emiseleni nasekugqokeni. Kuthuthukisa ukubambelela kwezibulala-zinambuzane kanye nomanyolo ukutshala izindawo zazo, kuthuthukisa ukusebenza kwazo.
Imboni yendwangu:I-HPMC iqashwa ekuphrintweni kwendwangu kanye nezinqubo zokudaya njengezikhulu zama-pastes wokuphrinta. Kuyasiza ukulawula i-viscosity yokunameka kokuphrinta futhi uthuthukise ubukhali kanye nombala wedizayini ophrintiwe.
Lezi yizibonelo ezimbalwa nje zezicelo eziningi ze-hydroxypropyllylylylylylyllose. Ukuguquguquka kwayo, ukuqina, futhi imvelo engeyona inobuthi yenza kube isithako esisetshenziswe kabanzi ezimbonini ezahlukahlukene.
