Hydroxy Ethyl Cellulose (HEC) Qhia

Hydroxy Ethyl Cellulose (HEC) yog non-ionic, dej-soluble polymer muab tau los ntawm cellulose. Nws yog cov hmoov dawb dawb, tsis muaj ntxhiab tsw thiab tsis qab, uas feem ntau siv los ua cov thickener, binder, stabilizer, thiab suspending agent nyob rau hauv ntau yam kev siv.

HEC tau siv dav hauv kev lag luam khoom noj khoom haus los ua cov khoom noj ntxiv los txhim kho kev ntxhib los mos, viscosity, thiab ruaj khov ntawm cov khoom noj xws li kua ntses, hnav khaub ncaws, thiab kua zaub. Nws kuj yog siv nyob rau hauv kev lag luam kws tshuaj raws li ib tug binder thiab raws li ib tug tswj-tso tus neeg saib xyuas nyob rau hauv cov tshuaj xa systems. Tsis tas li ntawd, HEC yog siv nyob rau hauv kev lag luam tshuaj pleev ib ce raws li ib tug thickener thiab emulsifier nyob rau hauv lotions, cream, thiab tshuaj zawv plaub hau.

HEC yog soluble hauv dej txias thiab dej kub, thiab nws cov viscosity tuaj yeem hloov kho los ntawm qhov sib txawv ntawm qhov hloov pauv (DS) ntawm pawg hydroxyl hauv cellulose molecule. Qhov siab dua DS ua rau muaj viscosity ntau dua ntawm HEC cov tshuaj.

HEC raug suav hais tias muaj kev nyab xeeb rau kev noj los ntawm US Food and Drug Administration (FDA) thiab European Food Safety Authority (EFSA). Nws yog ib tug ntau yam thiab nqi-zoo polymer uas yog dav siv nyob rau hauv ntau yam lag luam vim nws zoo heev thickening thiab stabilizing zog.
