1. Kev taw qhia txog HPMC
HPMC (Hydroxypropyl Methylcellulose)yog ib tug hluavtaws polymer compound muab los ntawm ntuj cellulose. Nws yog tsim los ntawm kev hloov kho tshuaj ntawm cellulose thiab yog siv dav hauv tshuaj, khoom noj khoom haus, tshuaj pleev ib ce thiab kev tsim kho. Vim tias HPMC yog dej-soluble, non-toxic, tasteless thiab non-irritating, nws tau dhau los ua cov khoom tseem ceeb hauv ntau yam khoom.
Hauv kev lag luam kws tshuaj, HPMC feem ntau yog siv los npaj cov tshuaj tiv thaiv-tso tawm cov tshuaj, cov tshuaj ntsiav, thiab cov tshuaj stabilizers. Nws kuj tau siv dav hauv cov khoom noj ua cov thickener, emulsifier, humectant thiab stabilizer, thiab txawm siv los ua cov khoom muaj calorie tsawg hauv qee cov khoom noj tshwj xeeb. Tsis tas li ntawd, HPMC kuj tseem siv los ua cov thickener thiab moisturizing muaj nyob rau hauv cov tshuaj pleev ib ce.
2. Qhov chaw thiab muaj pes tsawg leeg ntawm HPMC
HPMC yog ib qho cellulose ether tau los ntawm kev hloov kho tshuaj ntawm cov cellulose ntuj. Cellulose nws tus kheej yog polysaccharide muab rho tawm los ntawm cov nroj tsuag, uas yog ib feem tseem ceeb ntawm cov nroj tsuag cell phab ntsa. Thaum ua ke HPMC, cov pab pawg ua haujlwm sib txawv (xws li hydroxypropyl thiab methyl) tau qhia los txhim kho nws cov dej solubility thiab thickening zog. Yog li ntawd, lub hauv paus ntawm HPMC yog cov khoom siv cog qoob loo, thiab nws cov txheej txheem hloov kho ua rau nws soluble ntau thiab ntau yam.
3. Kev thov ntawm HPMC thiab kev sib cuag nrog tib neeg lub cev
Kev kho mob teb:
Hauv kev lag luam kws tshuaj, kev siv HPMC feem ntau cuam tshuam txog kev npaj tshuaj tiv thaiv-tso tawm. Txij li thaum HPMC tuaj yeem tsim cov gel txheej thiab tswj tau qhov tso tawm ntawm cov tshuaj zoo, nws yog siv dav hauv kev tsim cov tshuaj tiv thaiv-tso tawm thiab tswj-tso tshuaj. Tsis tas li ntawd, HPMC kuj tseem siv los ua lub plhaub capsule rau cov tshuaj, tshwj xeeb tshaj yog nyob rau hauv cov nroj tsuag capsules (cov neeg tsis noj nqaij capsules), qhov twg nws tuaj yeem hloov cov tsiaj gelatin thiab muab kev xaiv rau cov neeg tsis noj nqaij.
Los ntawm kev pom kev nyab xeeb, HPMC suav hais tias muaj kev nyab xeeb raws li cov khoom xyaw tshuaj thiab feem ntau muaj biocompatibility zoo. Vim tias nws tsis muaj tshuaj lom thiab tsis hnov tsw rau tib neeg lub cev, FDA (US Food and Drug Administration) tau pom zoo HPMC ua cov khoom noj ntxiv thiab cov tshuaj ntxiv, thiab tsis muaj kev phom sij rau kev noj qab haus huv los ntawm kev siv mus ntev tau pom.
Kev lag luam zaub mov:
HPMC yog dav siv nyob rau hauv kev lag luam khoom noj khoom haus, feem ntau yog ib tug thickener, stabilizer, emulsifier, thiab lwm yam. Nws yog dav siv nyob rau hauv cov khoom noj uas npaj txhij, dej haus, khoom qab zib, khoom noj siv mis, khoom noj khoom haus thiab lwm yam khoom. HPMC kuj feem ntau siv rau hauv kev tsim cov khoom uas tsis muaj calorie lossis cov rog tsawg vim nws cov dej-soluble zog, uas txhim kho saj thiab kev ntxhib los mos.
HPMC nyob rau hauv cov zaub mov yog tau los ntawm kev hloov tshuaj ntawm cov nroj tsuag cellulose, thiab nws cov concentration thiab kev siv feem ntau yog nruj me ntsis tswj raws li cov qauv rau kev siv cov khoom noj additives. Raws li kev tshawb fawb tshawb fawb tam sim no thiab cov qauv kev nyab xeeb khoom noj ntawm ntau lub teb chaws, HPMC suav tias yog kev nyab xeeb rau tib neeg lub cev thiab tsis muaj kev phom sij lossis kev phom sij rau kev noj qab haus huv.
Kev lag luam tshuaj pleev ib ce:
Hauv cov tshuaj pleev ib ce, HPMC feem ntau yog siv los ua cov thickener, emulsifier thiab moisturizing muaj. Nws yog dav siv nyob rau hauv cov khoom xws li cream, lub ntsej muag cleansers, qhov muag cream, lipsticks, thiab lwm yam. Vim hais tias HPMC yog mos thiab tsis khaus tawv nqaij, nws yog suav hais tias yog ib qho khoom xyaw haum rau txhua hom tawv nqaij, tshwj xeeb tshaj yog cov tawv nqaij rhiab.
HPMC kuj tseem siv cov tshuaj pleev thiab cov khoom kho tawv nqaij los pab txhim kho kev ruaj ntseg thiab nkag mus rau cov khoom xyaw tshuaj.
4. Kev nyab xeeb ntawm HPMC rau tib neeg lub cev
Kev ntsuam xyuas toxicological:
Raws li kev tshawb fawb tam sim no, HPMC suav hais tias muaj kev nyab xeeb rau tib neeg lub cev. Lub Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv (WHO), Lub Koom Haum Saib Xyuas Khoom Noj thiab Kev Ua Liaj Ua Teb (FAO), thiab US FDA tau soj ntsuam nruj heev ntawm kev siv HPMC thiab ntseeg tias kev siv tshuaj thiab zaub mov ntawm qhov ntau yuav tsis cuam tshuam rau tib neeg kev noj qab haus huv. FDA teev HPMC raws li "feem ntau lees paub tias muaj kev nyab xeeb" (GRAS) cov khoom siv thiab tso cai rau nws siv los ua zaub mov thiab tshuaj ntxiv.
Kev tshawb fawb soj ntsuam thiab kev soj ntsuam cov ntaub ntawv:
Ntau qhov kev tshawb fawb soj ntsuam tau pom tiasHPMCtsis ua rau muaj kev phiv los yog kev mob tshwm sim nyob rau hauv ib txwm siv. Piv txwv li, thaum HPMC siv rau hauv kev npaj tshuaj, cov neeg mob feem ntau tsis pom kev ua xua lossis lwm yam tsis xis nyob. Tsis tas li ntawd, tsis muaj teeb meem kev noj qab haus huv los ntawm kev siv HPMC ntau dhau hauv cov zaub mov. HPMC kuj tseem suav tias muaj kev nyab xeeb hauv qee cov neeg tshwj xeeb tshwj tsis yog tias muaj ib tus neeg tsis haum rau nws cov khoom xyaw.
Allergic Reactions thiab Adverse Reacts:
Txawm hais tias HPMC feem ntau tsis ua rau muaj kev tsis haum tshuaj, qee tus neeg tsis tshua muaj siab yuav muaj kev fab tshuaj rau nws. Cov tsos mob ntawm kev tsis haum tshuaj yuav muaj xws li daim tawv nqaij liab, khaus, thiab ua pa nyuaj, tab sis cov xwm txheej no tsawg heev. Yog tias kev siv cov khoom HPMC ua rau muaj kev tsis xis nyob, tsis txhob siv tam sim ntawd thiab sab laj nrog kws kho mob.
Cov teebmeem ntawm kev siv mus sij hawm ntev:
Kev siv HPMC mus ntev yuav tsis ua rau muaj kev cuam tshuam tsis zoo rau tib neeg lub cev. Raws li kev tshawb fawb tam sim no, tsis muaj pov thawj tias HPMC yuav ua rau lub cev puas tsuaj xws li daim siab thiab lub raum, thiab nws yuav tsis cuam tshuam rau tib neeg lub cev tiv thaiv kab mob lossis ua rau muaj kab mob ntev. Yog li ntawd, kev siv HPMC mus sij hawm ntev muaj kev nyab xeeb raws li cov qauv khoom noj thiab tshuaj uas twb muaj lawm.
5. Cov lus xaus
Raws li ib tug compound muab los ntawm tej yam ntuj tso nroj tsuag cellulose, HPMC yog dav siv nyob rau hauv ntau yam xws li tshuaj, zaub mov thiab tshuaj pleev ib ce. Ntau qhov kev tshawb fawb tshawb fawb thiab kev soj ntsuam toxicological tau pom tias HPMC muaj kev nyab xeeb nyob rau hauv ntau yam kev siv thiab tsis paub txog kev toxicity lossis kab mob txaus ntshai rau tib neeg lub cev. Txawm nyob rau hauv kev npaj tshuaj, khoom noj khoom haus additives los yog tshuaj pleev ib ce, HPMC yog suav hais tias yog ib tug muaj kev ruaj ntseg thiab zoo muaj. Tau kawg, rau kev siv cov khoom lag luam, cov kev cai cuam tshuam rau kev siv yuav tsum tau ua raws li, kev siv ntau dhau yuav tsum tau zam, thiab kev saib xyuas yuav tsum tau them rau cov neeg muaj kev tsis haum tshuaj thaum siv. Yog tias koj muaj teeb meem kev noj qab haus huv tshwj xeeb lossis kev txhawj xeeb, nws raug nquahu kom sab laj nrog kws kho mob lossis kws tshaj lij.
