Methyl cellulose, tseem hu ua methylcellulose, yog cov khoom sib xyaw ua ke los ntawm cellulose, uas yog ib yam khoom ntuj tsim muaj nyob hauv cov nroj tsuag. Nws yog dav siv nyob rau hauv ntau yam lag luam, nrog rau cov kws, khoom noj khoom haus, kev tsim kho, thiab tshuaj pleev ib ce. Methyl cellulose muaj nuj nqis rau nws cov khoom tshwj xeeb, xws li nws muaj peev xwm ua kom tuab, ruaj khov, emulsify, thiab muab kev ntxhib los mos hauv cov khoom sib txawv. Txawm li cas los xij, zoo li txhua yam tshuaj lom neeg, methyl cellulose kuj ua rau muaj kev phom sij thiab txaus ntshai, tshwj xeeb tshaj yog thaum siv tsis raug lossis ntau dhau.
Chemical Structure: Methyl cellulose yog muab los ntawm cellulose, complex carbohydrate pom nyob rau hauv cell phab ntsa ntawm cov nroj tsuag. Los ntawm cov txheej txheem tshuaj, pawg hydroxyl hauv cellulose molecules tau hloov nrog methyl pawg, ua rau methyl cellulose.
Khoom thiab Kev Siv: Methyl cellulose muaj nuj nqis rau nws lub peev xwm tsim cov gels, muab viscosity, thiab ua raws li tus neeg sawv cev thickening. Nws yog feem ntau siv nyob rau hauv kws tshuaj raws li ib tug binder nyob rau hauv cov ntsiav tshuaj formulations, nyob rau hauv cov khoom noj raws li ib tug thickener thiab stabilizer, nyob rau hauv kev tsim kho raws li ib tug additive nyob rau hauv cov cement thiab mortar, thiab nyob rau hauv cov tshuaj pleev ib ce raws li ib tug emulsifier thiab thickening neeg sawv cev.
Tam sim no, cia peb tshawb nrhiav cov kev phom sij cuam tshuam nrog methyl cellulose:
1. Teeb meem digestive:
Kev noj cov tshuaj methyl cellulose ntau tuaj yeem ua rau mob plab tsis zoo xws li tsam plab, roj, thiab raws plab. Methyl cellulose feem ntau yog siv los ua cov khoom noj fiber ntau ntxiv vim nws muaj peev xwm nqus dej thiab ntxiv rau cov quav. Txawm li cas los xij, kev noj ntau dhau yam tsis muaj dej txaus tuaj yeem ua rau cem quav ntau dhau los yog qhov sib txawv, ua rau cov quav xoob.
2. Kev ua xua:
Txawm tias tsis tshua muaj, qee tus neeg yuav muaj kev tsis haum tshuaj rau methyl cellulose. Cov tsos mob tuaj yeem tshwm sim los ntawm cov tawv nqaij me me mus rau qhov tshwm sim hnyav dua xws li ua pa nyuaj, o ntawm lub ntsej muag, daim di ncauj, lossis tus nplaig, thiab anaphylaxis. Cov neeg uas paub txog kev ua xua rau cellulose lossis lwm cov tshuaj sib txuas yuav tsum zam cov khoom uas muaj methyl cellulose.
3. Teeb meem ua pa:
Hauv cov chaw ua haujlwm, raug rau cov huab cua methyl cellulose tuaj yeem ua rau muaj teeb meem ua pa, tshwj xeeb tshaj yog rau cov tib neeg uas muaj kev ua pa ua ntej xws li mob hawb pob lossis mob ntsws ntsws ntev (COPD). Kev nqus cov plua plav lossis cov khoom aerosolized ntawm methyl cellulose tuaj yeem ua rau lub ntsws ua pa thiab ua rau muaj teeb meem ua pa uas twb muaj lawm.
4. Qhov muag Irritation:
Kev sib cuag nrog methyl cellulose hauv nws daim ntawv hmoov lossis kua tuaj yeem ua rau qhov muag khaus. Kev sib tsoo los yog raug rau cov khoom hauv huab cua thaum lub sij hawm tsim khoom tuaj yeem ua rau cov tsos mob xws li liab, tearing, thiab tsis xis nyob. Kev tiv thaiv qhov muag kom raug yuav tsum tau hnav thaum tuav methyl cellulose los tiv thaiv qhov muag khaus lossis raug mob.
5. Ib puag ncig Hazards:
Thaum methyl cellulose nws tus kheej yog suav tias yog biodegradable thiab ib puag ncig tus phooj ywg, nws cov txheej txheem tsim khoom yuav koom nrog kev siv tshuaj thiab cov txheej txheem siv zog uas ua rau muaj kuab paug ib puag ncig. Tsis tas li ntawd, kev pov tseg tsis raug ntawm cov khoom uas muaj methyl cellulose, xws li cov tshuaj los yog cov khoom siv tsim kho, tuaj yeem ua rau muaj paug hauv av thiab dej.
6. Kev sib cuam tshuam nrog cov tshuaj:
Hauv kev lag luam kws tshuaj, methyl cellulose feem ntau yog siv los ua ib qho ntxiv hauv cov ntsiav tshuaj formulations. Thaum feem ntau suav hais tias muaj kev nyab xeeb, muaj peev xwm cuam tshuam nrog qee yam tshuaj. Piv txwv li, methyl cellulose tuaj yeem cuam tshuam rau kev nqus los yog tso tawm cov khoom xyaw nquag hauv cov ntsiav tshuaj, ua rau muaj kev hloov pauv ntawm kev siv tshuaj los yog bioavailability. Cov neeg mob yuav tsum sab laj nrog kws kho mob yog tias lawv muaj kev txhawj xeeb txog kev cuam tshuam nrog cov tshuaj uas lawv noj.
7. Kev Ua Haujlwm Kev Nyab Xeeb:
Cov neeg ua haujlwm koom nrog hauv kev tsim lossis tuav cov khoom lag luam methyl cellulose tuaj yeem raug cuam tshuam rau ntau yam kev ua haujlwm, suav nrog kev nqus cov pa hauv huab cua, kev sib cuag ntawm daim tawv nqaij nrog kev daws teeb meem, thiab qhov muag raug rau cov hmoov lossis kua dej. Kev ntsuas kev nyab xeeb kom raug, suav nrog kev siv cov cuab yeej tiv thaiv tus kheej (PPE) xws li hnab looj tes, tsom iav, thiab kev tiv thaiv ua pa, yuav tsum tau ua kom txo qis kev pheej hmoo.
8. Risk of Choking:
Hauv cov khoom noj khoom haus, methyl cellulose feem ntau yog siv los ua cov thickening lossis bulking tus neeg sawv cev los txhim kho kev ntxhib los mos thiab sib xws. Txawm li cas los xij, kev siv ntau dhau los lossis kev npaj tsis raug ntawm cov khoom noj uas muaj methyl cellulose tuaj yeem ua rau muaj kev pheej hmoo ntawm chua leeg, tshwj xeeb tshaj yog rau cov menyuam yaus lossis cov neeg laus uas muaj teeb meem nqos. Kev saib xyuas yuav tsum tau ua raws li cov lus pom zoo rau kev siv methyl cellulose hauv kev npaj zaub mov.
9. Cov teebmeem tsis zoo rau Kev Kho Hniav:
Qee cov khoom siv kho hniav, xws li cov khoom siv kho hniav, tuaj yeem muaj methyl cellulose ua tus neeg ua kom tuab. Ntev ntev raug rau cov khoom siv kho hniav uas muaj methyl cellulose tuaj yeem ua rau cov quav hniav ntau ntxiv thiab ua rau muaj kev pheej hmoo ntawm cov hniav lwj thiab cov pos hniav. Kev tu lub qhov ncauj kom zoo, suav nrog kev txhuam hniav thiab txhuam hniav, yog qhov tseem ceeb rau kev txo cov kev pheej hmoo no.
10. Kev Tswj Xyuas Kev Nyab Xeeb:
Thaum methyl cellulose feem ntau lees paub tias muaj kev nyab xeeb (GRAS) rau kev siv khoom noj thiab tshuaj siv los ntawm cov koom haum tswj hwm xws li US Food and Drug Administration (FDA), kev txhawj xeeb yuav tshwm sim hais txog qhov purity, zoo, thiab daim ntawv lo ntawm cov khoom uas muaj methyl cellulose. Cov neeg tsim khoom yuav tsum ua raws li cov kev cai nruj thiab cov qauv kev tswj xyuas kom muaj kev nyab xeeb thiab kev ua tau zoo ntawm lawv cov khoom.
thaum methyl cellulose muaj ntau yam txiaj ntsig hauv ntau yam kev lag luam, suav nrog tshuaj, khoom noj, kev tsim kho, thiab tshuaj pleev ib ce, nws yog ib qho tseem ceeb kom paub txog qhov muaj peev xwm txaus ntshai thiab kev pheej hmoo cuam tshuam nrog kev siv. Los ntawm cov teeb meem digestive thiab kev ua xua rau cov teeb meem ua pa thiab kev puas tsuaj ib puag ncig, yuav tsum tau ua tib zoo xav txog kev tuav, noj, thiab pov tseg cov khoom uas muaj methyl cellulose. Los ntawm kev nkag siab txog cov kev phom sij no thiab ua raws li cov kev ntsuas kev nyab xeeb thiab cov kev cai tsim nyog, peb tuaj yeem txo qhov kev pheej hmoo thiab ua kom tau txais txiaj ntsig zoo tshaj plaws ntawm cov khoom siv ntau yam no.
