Sodium carboxymethyl cellulose nyob rau hauv cov tshuaj txhuam hniav

Taw qhia

Sodium carboxymethyl cellulose (CMC) yog cov khoom siv dav hauv cov tshuaj txhuam hniav. Nws yog ib hom cellulose derivative, uas yog ib tug polymer ntawm qabzib molecules. CMC yog siv rau hauv ntau yam khoom, nrog rau cov khoom noj, tshuaj, thiab tshuaj pleev ib ce. Hauv cov tshuaj txhuam hniav, CMC ua raws li tus neeg sawv cev thickening, stabilizer, thiab emulsifier. Nws pab kom cov tshuaj txhuam hniav tsis txhob sib cais thiab muab ib qho smooth, creamy zoo nkauj. CMC kuj tseem pab txhawm rau khi lwm cov khoom xyaw ua ke, ua rau cov tshuaj txhuam hniav yooj yim dua thiab muab nws lub neej txee ntev dua.

Keeb kwm ntawm Sodium Carboxymethyl Cellulose hauv tshuaj txhuam hniav

Sodium carboxymethyl cellulose tau siv rau hauv cov tshuaj txhuam hniav txij thaum xyoo pua 20th. Nws yog thawj zaug tsim nyob rau xyoo 1920 los ntawm tus kws tshawb fawb German, Dr. Karl Ziegler. Nws pom tias ntxiv sodium rau cellulose tsim ib hom tshiab polymer uas ruaj khov thiab siv tau yooj yim dua li cov cellulose. Cov polymer tshiab no hu ua carboxymethyl cellulose, lossis CMC.

Xyoo 1950, CMC tau pib siv tshuaj txhuam hniav. Nws tau pom tias yog tus neeg ua haujlwm thickening zoo thiab stabilizer, thiab nws pab kom cov tshuaj txhuam hniav sib cais. CMC kuj tau muab ib qho kev ntxhib los mos zoo nkauj thiab pab khi lwm cov khoom xyaw ua ke, ua rau cov tshuaj txhuam hniav yooj yim dua thiab muab nws lub neej ntev dua.

Cov txiaj ntsig ntawm Sodium Carboxymethyl Cellulose hauv tshuaj txhuam hniav

Sodium carboxymethyl cellulose muaj ntau yam txiaj ntsig thaum siv tshuaj txhuam hniav. Nws ua raws li tus neeg sawv cev thickening, stabilizer, thiab emulsifier, pab kom cov tshuaj txhuam hniav sib cais thiab muab ib tug du, creamy zoo nkauj. CMC kuj tseem pab txhawm rau khi lwm cov khoom xyaw ua ke, ua rau cov tshuaj txhuam hniav yooj yim dua thiab muab nws lub neej txee ntev dua.

Tsis tas li ntawd, CMC pab txo qis cov khoom xyaw abrasive hauv cov tshuaj txhuam hniav. Qhov no yog ib qho tseem ceeb vim hais tias cov khoom xyaw abrasive tuaj yeem ua rau cov hniav enamel puas thiab ua rau rhiab heev. CMC pab txo cov abrasiveness ntawm cov tshuaj txhuam hniav, ua rau nws softer ntawm cov hniav thiab cov pos hniav.

Thaum kawg, CMC pab txhim kho cov saj ntawm cov tshuaj txhuam hniav. Nws pab ua kom lub ntsej muag tsis hnov ​​​​tsw thiab ntxhiab tsw, ua rau cov tshuaj txhuam hniav zoo nkauj siv.

Kev nyab xeeb ntawm Sodium Carboxymethyl Cellulose hauv tshuaj txhuam hniav

Sodium carboxymethyl cellulose feem ntau suav hais tias muaj kev nyab xeeb thaum siv tshuaj txhuam hniav. Nws tau pom zoo los ntawm US Food and Drug Administration (FDA) siv rau hauv cov khoom noj, tshuaj, thiab tshuaj pleev ib ce. CMC kuj tau pom zoo los ntawm American Dental Association (ADA) rau kev siv tshuaj txhuam hniav.

Tsis tas li ntawd, CMC tsis muaj tshuaj lom thiab tsis ua rau khaus. Nws tsis ua rau muaj kev phiv tshuaj thaum siv tshuaj txhuam hniav.

Thaum kawg, CMC pab txhim kho cov saj ntawm cov tshuaj txhuam hniav, ua kom nws qab ntxiag rau kev siv. Zuag qhia tag nrho, CMC yog cov khoom muaj kev nyab xeeb thiab siv tau zoo hauv cov tshuaj txhuam hniav.
