Qhov sib txawv tseem ceeb ntawm sodium hyaluronate thiab carboxymethylcellulose yog tias sodium hyaluronate qhia tau zoo heev moisturizing thiab mucus-txheej nplaum nplaum, whereas carboxymethylcellulose muab cov yam ntxwv zoo bio-adhesive thiab nws tuaj yeem ua rau lub sij hawm tsim kua muag.
Sodium hyaluronate thiab carboxymethylcellulose yog cov tshuaj tseem ceeb hauv lubricating qhov muag tee rau qhov muag qhuav. Cov no yog cov khoom xyaw tseem ceeb hauv qhov muag te.
Sodium Hyaluronate yog dab tsi?
Sodium hyaluronate tuaj yeem piav qhia raws li sodium ntsev ntawm hyaluronic acid. Hauv lwm lo lus, nws yog glycosaminoglycan uas muaj cov saw hlau ntev ntawm cov disaccharide units. Cov disaccharide units muaj Na-glucuronate-N-acetylglucosamine. Tsis tas li ntawd, sodium hyaluronate tuaj yeem khi nrog cov receptors tshwj xeeb uas muaj kev sib raug zoo siab rau qhov sib xyaw no. Daim ntawv polyanionic ntawm no compound yog "hyaluronan." Nws yog visco-elastic polymer. Cov tshuaj no muaj nyob rau hauv extracellular matrix ntawm mammalian connective, epithelial, thiab neural ntaub so ntswg.
Daim duab 01: Cov Qauv Tshuaj ntawm Sodium Hyaluronate
Tsis tas li ntawd, sodium hyaluronate tshwm sim hauv lub pob ntseg endothelium. Lub luag haujlwm tseem ceeb ntawm qhov sib xyaw no yog tias nws ua lub luag haujlwm rau cov ntaub so ntswg thiab hloov kev sib cuam tshuam ntawm cov ntaub so ntswg uas nyob ib sab. Thaum yaj hauv dej, nws tuaj yeem tsim cov tshuaj visco-elastic. Thaum txhaj rau hauv lub cev, sodium hyaluronate ploj hauv cov xuab moos tom qab txhaj tshuaj. Tab sis muaj cov teebmeem residual ntawm cov hlwb hu. Cov kev mob tshwm sim ntawm cov tshuaj no (thaum siv los ua kev txhaj tshuaj) suav nrog kev mob tom qab phais thiab pob txha edema.
Carboxymethylcellulose (Cellulose Gum) yog dab tsi?
Carboxymethylcellulose tseem hu ua cellulose gum. Nws yog abbreviated li CMC. Peb tuaj yeem txhais tau tias nws yog cellulose derivative muaj carboxymethyl pawg uas tau khi rau qee pawg hydroxyl ntawm glucopyranose monomers hauv cov pob txha cellulose. Feem ntau, CMC yog qhov tseem ceeb hauv nws daim ntawv ntsev ntsev. Nws yog lub npe hu ua sodium CMC. Lub npe lag luam rau qhov sib xyaw no hauv kev ua lag luam yog Tylose.
Daim duab 02: Cov qauv tshuaj ntawm CMC
Nyob rau hauv kev npaj ntawm CMC, peb yuav tsum tau ua ke nws los ntawm alkali-catalyzed cov tshuaj tiv thaiv ntawm cellulose nyob rau hauv lub xub ntiag ntawm chloroacetic acid. Hauv cov txheej txheem no, cov pawg polar carboxyl ua rau solubility ntawm cellulose thiab tshuaj reactivity. Tom qab ua tiav thawj kauj ruam no, cov tshuaj tiv thaiv tshwm sim feem ntau muaj li 60% CMC thiab 40% sodium ntsev xws li sodium chloride thiab sodium glycolate. Peb tuaj yeem piav qhia txog cov khoom sib xyaw no raws li kev CMC, uas muaj txiaj ntsig zoo hauv kev tsim cov tshuaj ntxuav tes. Tom qab ntawd, peb xav tau lwm kauj ruam ua kom huv huv kom tshem tawm cov ntsev sib xyaw thiab ntxuav cov CMC compound. CMC ntshiab no muaj txiaj ntsig zoo hauv kev lag luam zaub mov, kev lag luam tshuaj, thiab kev tsim tshuaj txhuam hniav. Tsis tas li ntawd, muaj cov khoom lag luam semi-purified ib yam nkaus, uas yog ib qho tseem ceeb hauv daim ntawv thov, suav nrog kev kho dua tshiab ntawm cov ntaub ntawv khaws cia.
Muaj ntau daim ntawv thov ntawm CMC, suav nrog kev lag luam khoom noj, qhov twg nws muaj tus lej E E466 lossis E469 (cov ntawv enzymatically hydrolyzed), uas yog qhov muaj txiaj ntsig zoo li lub viscosity modifier thiab ua cov thickener. Tsis tas li ntawd, nws yog ib qho tseem ceeb rau stabilizing emulsions hauv cov khoom xws li ice cream. Tsis tas li ntawd, CMC muaj txiaj ntsig zoo hauv kev tsim cov tshuaj txhuam hniav, tshuaj laxatives, tshuaj noj, tshuaj pleev xim dej, tshuaj ntxuav tes, textile sizing, ntawv khoom, thiab lwm yam.
Qhov txawv ntawm Sodium Hyaluronate thiab Carboxymethylcellulose yog dab tsi?
Ob qho tib si sodium hyaluronate thiab CMC compounds yog cov khoom xyaw tseem ceeb hauv cov tee dej. Qhov sib txawv tseem ceeb ntawm sodium hyaluronate thiab carboxymethylcellulose yog tias sodium hyaluronate qhia tau zoo heev moisturizing thiab mucus-txheej nplaum cov khoom, whereas carboxymethylcellulose muab cov yam ntxwv zoo bioadhesive thiab nws tuaj yeem ua rau lub sij hawm tsim kua muag.
Cov hauv qab no qhia txog qhov sib txawv ntawm sodium hyaluronate thiab carboxymethylcellulose hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Sodium Hyaluronate vs Carboxymethylcellulose
Sodium hyaluronate yog sodium ntsev ntawm hyaluronic acid. Carboxymethylcellulose tseem hu ua cellulose gum. Ob lub tebchaw no yog cov khoom xyaw tseem ceeb hauv qhov muag tee. Qhov sib txawv tseem ceeb ntawm sodium hyaluronate thiab carboxymethylcellulose yog tias sodium hyaluronate qhia tau zoo heev moisturizing thiab mucus-txheej nplaum cov khoom, whereas carboxymethylcellulose muab cov yam ntxwv zoo bioadhesive thiab tuaj yeem ua rau lub sij hawm tsim kua muag.
