Daim ntawv thov ntawm Ethyl cellulose hauv kev npaj tshuaj

Ethylcellose (EC)yog ib semi-hluavtaws polymer compound tau los ntawm kev ua kom zoo ntawm lub ntuj cog cellulose. Cov qauv molecular yog tsim cov chav dej qab zib uas sib txuas los ntawm β-1,4-glycosidic bonds. Vim tias nws zoo biocompatibility, tsis muaj txiaj ntsig, zoo txhawb thiab muaj txiaj ntsig zoo, kev coj ua tau dav hauv kev npaj tshuaj, tshwj xeeb hauv kev lag luam kws tshuaj.

1. Cov khoom yooj yim ntawm Ethyl cellulose

Ethyl cellulose muaj cov biocompatibility high biocompatibility thiab tuaj yeem muaj nyob rau hauv tib neeg lub cev tau ntev yam tsis tau luam cov tshuaj lom. Nws cov qauv tshuaj muab nws zoo hydrophobicity, ruaj khov, acid thiab alkali tsis kam thiab qee cov khoom tso tawm. Tsis tas li ntawd, Ethyl cellulose yog insoluble hauv dej, tab sis soluble hauv cov kuab tshuaj ethanol, acetone, thiab lwm yam ntawm cov ntawv thov kev npaj khoom hauv chaw tsim khoom.

2. Daim ntawv thov ntawm Ethyl cellulose hauv kev npaj tshuaj

Daim ntawv thov teb ntawm cov tshuaj phais tshuaj yog qhov dav heev, cov tshuaj tiv thaiv kab, kev npaj sab nraud thiab lwm yam kev npaj ntau yam. Cov hauv qab no yog ob peb daim ntawv thov ntawm Ethyl cellulose hauv kev npaj tshuaj.

2.1 Kev Tso Tawm-Tso Tawm Rau Qhov Muag Yeeb Tshuaj

Qhov kev thov feem ntau ntawm Ethyl cellulose yog raws li kev tswj hwm tus neeg sawv cev, tshwj xeeb hauv kev tswj hwm qhov ncauj. Lub Hydrophobic Xwm thiab cov kev koom tes ntawm cov tshuaj tua kab ua kom nws muaj cov tshuaj zoo tshaj tawm-tso tawm. Hauv kev siv tshuaj rau kev npaj-tso tawm, cov cellule Ethyl tuaj yeem ncua cov tshuaj ua yeeb yaj kiab, yog li ua tiav lub hom phiaj ntawm kev siv tshuaj. Los ntawm kev kho cov molecular hnyav ntawm Ethyling Cellulose, qhov tuab ntawm txheej txheej txheej thiab kev tso tawm thiab tso tawm hom tshuaj tuaj yeem tswj tau.

Ethyl Cellulose feem ntau yog siv los npaj cov khoom noj kom haum rau qhov ncauj. Cov tshuaj yog qhwv hauv cov yeeb yaj kiab ntawm lub cev. Cov txheej txheem tso tawm tshuaj tuaj yeem tswj tau los ntawm o thiab solubility ntawm zaj duab xis thiab nkag mus rau ntawm cov kuab tshuaj. Raws li cov qauv sib txawv thiab cov txheej txheem sib txawv, cov kws tshuaj Ethyl yuav tuaj yeem tswj lub sijhawm tso tawm ntawm cov tshuaj, txo lub sijhawm noj tshuaj, thiab txhim kho kev ua raws li kev ua raws.

2.2 Tshuaj Zaj Duab Xis Txheej

Hauv kev npaj cov tshuaj, cov cellulose Etheny tseem siv rau cov txheej txheem zaj duab xis, tshwj xeeb tshaj yog hauv qhov ncauj npaj xws li ntsiav tshuaj, granules thiab capsules. Raws li cov khoom ua yeeb yaj kiab ua yeeb yaj kiab, cov tshuaj tiv thaiv Ethyl muaj cov lus pom zoo, muaj zog thiab ua kom muaj kev tiv thaiv cov pa roj av thiab ua kom muaj kev tiv thaiv cov pa roj av hauv lub plab zom mov. Nyob rau tib lub sij hawm, kev coj ua yeeb yaj kiab cellulose tuaj yeem tswj hwm cov tshuaj tso tawm, tshwj xeeb yog los ntawm kev kho cov yeeb yaj kiab tuab thiab siv cov kuab sib txawv, sib txawv tso cov nkhaus yuav ua tiav.

Raws li cov khoom siv txheej, cov cellulose Etheny kuj tseem tuaj yeem txhim kho cov tshuaj saj, zam kev tawg lossis tsis xis nyob, thiab ua rau tus neeg mob tsis xis nyob.

2.3 emulsion thiab miellar npaj

Vim yog nws solubility thiab cov khoom sib tw, cov cellulose kuj tseem siv tau dav hauv emulsions thiab polellar npaj. Nyob rau hauv kev npaj emulsions, Ethyl cellulose, raws li ib tug emulsifier thiab stabilizer, tuaj yeem txhim kho cov solubility ntawm cov tshuaj. Tshwj xeeb tshaj yog rau qee cov roj av-soluble yeeb tshuaj tuaj yeem pab rau cov yeeb tshuaj uas tsis txaus ntseeg, txo cov dej nag lossis daus ntawm cov tshuaj.

Hauv Mickellar npaj, Ethylle cellulose, raws li lub stabuler, tuaj yeem tsim cov qauv siv micellilas thiab cov tshuaj lom neeg ntawm lub cev, tshwj xeeb tshaj yog rau qee cov tshuaj tsis zoo.

2.4 Cov Tshuaj Tso Nrog Tshuaj Tiv Thaiv

Kimacell®ethyl cellulose tseem muaj dav siv cov tshuaj tawm sab nrauv, tshwj xeeb tshaj yog nyob rau hauv kev npaj cov tshuaj pleev, cream, kua pleev thiab lwm yam kev npaj. Raws li cov tuab yaj duab, zaj duab xis yav tas los thiab cellulose tuaj yeem txhim kho cov kev sib tw, cov tshuaj nplaum thiab cov yeeb yaj kiab. Hauv cov ntsiab lus npaj xws li tshuaj pleev thiab cov cream, cov cellule ethyl tuaj yeem txhim kho cov kev xa tawm thiab kev tso tawm ntawm cov tshuaj thaum siv.

2.5 Cov Qauv Yeeb Tshuaj

Cov cellulose Etheny tseem tuaj yeem siv ua cov khoom siv yeeb tshuaj, tshwj xeeb tshaj yog nyob rau hauv kev npaj Nanocarrien thiab cov micrapharriers. Cov cellulose Ethulose tuaj yeem tsim cov nyiaj nrog cov molecules los muab tshuaj tswj cov tshuaj zoo dua. Hauv Nanocarrier Systems, cov khoom ntawm cov tshuaj tua kab mob yog txhim kho kev thauj cov tshuaj thiab tso tawm kev tswj hwm tus nqi.

3. Qhov zoo thiab cov nyom ntawm Ethyl cellulose

Raws li kev zam rau kev npaj tshuaj, kimacell®ethyl cellulose muaj ntau yam zoo. Nws muaj zoo biocompatibility thiab biodegradability, uas tuaj yeem txo cov teebmeem tsis zoo rau tib neeg lub cev; Nws tuaj yeem daws cov tshuaj tso tawm thiab txhim kho cov kev kho mob ntawm cov tshuaj; Tsis tas li ntawd, kev siv cov thev naus laus zis ntawm Ethyl cellulose tau paub tab, siv dav, tus nqi qis, thiab tsim nyog rau cov khoom loj. Txawm li cas los xij, lub ethyl cellulose tseem ntsib qee qhov kev cov nyom. Piv txwv li, nyob rau hauv qee qhov tseem ceeb ntawm cov kev mob siab lossis cov kev mob siab tshaj plaws, qhov ruaj khov ntawm Ethyl cellulose yuav txo qis, uas yuav cuam tshuam rau cov chaw tshwj xeeb.

Ethyl CelluloseMuaj ntau yam kev thov kev cia siab hauv kev npaj tshuaj, tshwj xeeb tshaj yog nyob rau hauv cov liaj teb ntawm cov tswj-tso tawm, yeeb yaj kiab ua yeeb yaj kiab, emulsions, thiab npaj primical. Nws cov khoom siv lub cev thiab tshuaj lom neeg ua rau nws tsis muaj peev xwm ua tau qhov kev npaj ua tshuaj. Txawm li cas los xij, hauv cov ntawv thov siv, nws yog tseem tsim nyog kom ua kom zoo thiab txhim kho kev sib tw ntawm cov tshuaj thiab cov neeg mob ua tsaug.
