Puas yog HEC natural?

HEC tsis yog ib yam khoom ntuj tsim. Nws yog ib tug hluavtaws polymer muab tau los ntawm cellulose, uas yog ib txwm tshwm sim polysaccharide pom nyob rau hauv cov nroj tsuag. Hydroxyethyl cellulose HEC yog ib qho dej-soluble polymer uas yog siv rau ntau yam kev siv, xws li ua cov thickening agent, emulsifier, stabilizer, thiab suspending agent.

HEC yog tsim los ntawm reacting cellulose nrog ethylene oxide, roj-derived tshuaj. Cov tshuaj tiv thaiv no tsim cov polymer nrog hydrophilic (dej-hlub) xwm, uas ua rau nws soluble hauv dej. HEC yog cov hmoov dawb, dawb-ntws uas tsis muaj ntxhiab thiab tsis qab. Nws tsis yog flammable thiab ruaj khov nyob rau ntau qhov kub thiab txias thiab pH qib.

HEC yog siv nyob rau hauv ntau yam kev lag luam, nrog rau cov khoom noj, tshuaj, tshuaj pleev ib ce, thiab cov khoom tu tus kheej. Hauv cov khoom noj, nws yog siv los ua cov thickener, emulsifier, thiab stabilizer. Hauv kev lag luam tshuaj, nws yog siv los ua tus neeg sawv cev ncua thiab cov ntsiav tshuaj binder. Hauv cov tshuaj pleev ib ce thiab cov khoom tu tus kheej, nws yog siv los ua cov thickener thiab stabilizer.

HEC feem ntau suav hais tias muaj kev nyab xeeb rau kev siv khoom noj, tshuaj, thiab tshuaj pleev ib ce. Nws tau pom zoo siv hauv Tebchaws Meskas thiab Tebchaws Europe, thiab tau teev nyob rau hauv FDA's Generally Recognized as Safe (GRAS).

HEC tsis yog cov khoom siv ntuj tsim, tab sis nws yog cov khoom muaj kev nyab xeeb thiab muaj txiaj ntsig zoo uas tau siv dav hauv ntau lub lag luam. Nws yog ib qho tseem ceeb ntawm ntau yam khoom, thiab nws cov versatility ua rau nws muaj txiaj ntsig zoo rau ntau daim ntawv thov.
