Carboxymethyl cellulose (CMC) yog ib qho tseem ceeb ntawm cov zaub mov zoo nkauj, uas tau siv dav hauv cov zaub mov, tshuaj, tshuaj pleev ib ce, roj tawm thiab lwm thaj teb. Raws li kev sib txuam ua ke ntau ntxiv, CMC muaj cov tuab tuab, stabilization, zaj duab xis-sib sau, moisturizing thiab lwm yam khoom. Piv nrog rau lwm cov ntawv tuab, cmc tus qauv tshwj xeeb thiab cov khoom ua rau nws sawv hauv ntau daim ntawv thov.
1. Cov qauv tshuaj
Carboxymethyl cellulose
Carboxymethyl cellulose yog anionic cellulose eteetic ua los ntawm kev qhia cov pab pawg carboxymesyl rau hauv cov cellulose ntuj tom qab kev sib tw. Nws cov txheej txheem theem pib yog cov piam thaj, thiab carboxymethyl hloov ib feem ntawm cov pawg hydroxyl (-O) Cov qauv no ua rau CMC muaj siab solubility hauv dej thiab zoo rheological cov khoom.
Lwm yam thickeners
Xanthan ntawm cov pos hniav: Xanthan ntawm cov pos hniav yog lub siab loj polysaccharide tsim los ntawm fermentation ntawm xanthomonas. Nws cov saw tseem yog tsim ntawm β-d-glucan, thiab nws sab sa sab acid, thiab lwm yam.
Guar pos hniav: guar pos hniav yog muab rho tawm los ntawm endosperm ntawm gloar taum thiab belongs rau galactomannan. Lub ntsiab tseem ceeb yog tsim los ntawm d-mannose thiab sab saw hlau yog D-galactose. Cov pos hniav guar yog yooj yim soluble hauv dej txias thiab ua lub siab-viscosity colloid.
Pectin: pectin yog polysaccharide tam sim no hauv tsob ntoo cell phab ntsa, thiab nws cov metracturonic acid, thiab nws cov methoxylation degree cuam tshuam rau nws cov khoom muaj nuj nqi. Pectin muaj cov khoom lag luam zoo hauv cov acidic ib puag ncig.
HydroxyPropyyl methylcellueculose (HPMC): HPMC yog ib qho kev ua yeeb yam ntawm methylcellulose nrog cov qauv hydroxyprropylated thiab methylated qauv. HPMC muaj kev lom zem ua kom zoo thiab thickening cov khoom hauv dej.
2. Thickenance
Carboxymethyl cellulose
Tom qab CMC yog yaj hauv dej, cov pab pawg carboxymethyl ua rau nws muaj zoo hydrophilicity, thiab cuam tshuam nrog cov roj av molecules los ntawm kev sib sau tshuaj hydrogen bonds thiab van der WAsals rog. Nws cov txheej txheem tuab yog ua kom muaj kuab tshuaj ntawm kev daws teeb meem los ntawm kev ua haujlwm thiab tsis meej pem ntawm cov lwg me me. Tsis tas li ntawd, CMC muaj kev ruaj khov nyob rau hauv acidic los yog alkaline tej yam kev mob thiab tau siv dav hauv cov kab ke nrog cov laj kab sib txawv.
Lwm yam thickeners
Xanthan ntawm cov pos hniav: Xanthan ntawm cov pos hniav nce viscosity ntawm kev daws los ntawm kev ua haujlwm thiab hydrogen kev ntawm ntev-saw molecules. Nws tshwj xeeb shear cov khoom uas ua rau viscnosity kom txo sai thaum raug shear zog, thiab rov kho cov viscosity siab thaum nyob ruaj ruaj.
Guar pos hniav: Guar ntawm cov pos hniav nce viscosity ntawm kev daws teeb meem los ntawm kev tsim tus ntoo khaub ncaws txuas nrog thiab o ntawm dej nqus. Nws cov qauv molecular tuaj yeem tsim cov kab ke volloidal heev.
Pectin: Pectin cov ntaub ntawv Hydrogen Bonds nrog dej molecules los ntawm cov roj carboxyl ntawm nws sab saw. Nws tuaj yeem tsim cov gel network nrog calcium ions nyob rau hauv acidic tej yam kev mob, loj hlob lub viscosity ntawm kev daws.
HydroxyPropyyl methylulose: HPMC nce viscosity ntawm kev daws los ntawm kev ua haujlwm ntawm cov lwg me me thiab kev tsim ntawm hydrogen bonds. Nws cov solubility thiab viscosity sib txawv heev nyob rau hauv cov kub kub tshwm sim, thiab nws muaj qee yam thermal gel khoom.
3. Daim ntawv thov
Carboxymethyl cellulose
Kev Lag Luam Khoom Noj: CMC feem ntau siv hauv cov zaub mov xws li cov khoom noj mis nyuj, khob cij, khob cij, ua kom huv, noo noo, thiab txhim kho kev ntxhib.
Tshuaj: Hauv cov chaw muag tshuaj: hauv cov phau ntawv sib dhos, CMC yog siv los ua cov phau ntawv thiab tsis muaj kev cuam tshuam rau cov ntsiav tshuaj, thiab tseem siv lubricalic thiab roj pleev roj pleev.
Cov tshuaj pleev ib ce: CMC yog siv rau hauv cov tshuaj pleev ib ce xws li lotions thiab cream, thiab muaj cov moisturizing thiab ruaj khov ua haujlwm.
Kev lag luam roj av: hauv cov roj ntau lawm, CMC yog siv rau hauv cov kua dej khov thiab av nkos kom tuab thiab txo cov kev lim.
Lwm yam thickeners
Xanthan ntawm cov pos hniav: siv cov zaub mov, tshuaj pleev ib ce, tshwj xeeb, tshwj xeeb yog cov kua ntses, cov kua ntses, thiab emulsifiers.
Guar pos hniav: feem ntau siv nyob rau hauv cov zaub mov xws li cov mis nyuj khov, cov khoom noj mis nyuj, thiab zaub xam lav kom muab cov tshuaj ntsuab siab thiab ruaj khov; Siv los ua cov tuab thiab tawv thiab khov kho hauv kev lag luam thiab textile.
Pectin: Feem ntau yog siv nyob rau hauv cov zaub mov xws li jams, jellies, candies mos, vim hais tias ntawm nws cov gel cov khoom, nws ua tau zoo nyob rau hauv cov piam thaj ntau thiab acidic ib puag ncig.
HydroxyPropyyl methylulose: Siv hauv cov khoom lag luam, siv hauv cov khoom siv hauv tsev, ntxiv cov zaub mov, thiab lwm yam tshuaj.
3. Kev Nyab Xeeb
Carboxymethyl cellulose
CMC tau dav yog tias muaj zaub mov muaj kev nyab xeeb ntxiv thiab ua tau raws li cov qauv kev nyab xeeb ntawm cov neeg muaj kev nyab xeeb. Thaum cov nyiaj siv tau ua raws li cov cai kav, CMC yog tsis muaj tshuaj lom rau tib neeg lub cev. Nws tseem qhia zoo biocompatibility thiab tsawg tsis haum thaum siv raws li cov tshuaj uas muaj kev zam thiab cov tshuaj pleev ib ce.
Lwm yam thickeners
Xanthan ntawm cov pos hniav: ua zaub mov muaj ntxiv, xanthan ntawm cov pos hniav yog feem ntau suav hais tias muaj kev nyab xeeb, tab sis cov koob tshuaj yuav ua rau muaj kev tsis xis nyob.
Guar pos hniav: Nws tseem muaj cov zaub mov muaj kev nyab xeeb ntxiv, tab sis muaj ntau dhau yuav ua rau mob plab xws li bloating.
Pectin: Feem ntau suav tias muaj kev nyab xeeb, tab sis tuaj yeem ua rau kev ua xua nyob rau hauv tus kheej.
HydroxyPropyyl Metylcellulose: raws li kev khaws khoom siv thiab khoom noj ntxiv, HPMC muaj kev nyab xeeb zoo, tab sis nws cov kev nyab xeeb yuav tsum ua raws li cov cai.
Carboxymethyl cellulose qhia nws cov txiaj ntsig tshwj xeeb hauv kev sib piv nrog lwm cov thickeners, nrog rau cov dej solubility, versatility thiab ntau ntawm cov ntawv thov. Txawm hais tias lwm cov thickeners yuav muaj qhov zoo hauv cov cheeb tsam tshwj xeeb, CMC tseem muaj qhov kev ua lag luam zoo tshaj plaws vim nws txoj kev nyab xeeb thiab kev nyab xeeb zoo. Thaum xaiv cov tuab dua, nws yog qhov tsim nyog kom muaj kev nkag siab ntau yam xws li thickening kev ua tau zoo, kev siv kev nyab xeeb kom ua tiav cov nyhuv zoo.
