Puas yog hydroxyethylcellulose muaj teeb meem?

Hydroxyethylcellulose (HEC) yog ib qho hluavtaws polymer muab tau los ntawm cellulose, ib tug natural polysaccharide pom nyob rau hauv cov nroj tsuag.HEC yog cov khoom tsis muaj tshuaj lom, tsis ua rau khaus, thiab tsis ua xua uas siv rau hauv ntau yam khoom, suav nrog tshuaj pleev ib ce, tshuaj, thiab khoom noj khoom haus.Nws kuj yog siv rau hauv kev lag luam kev siv, xws li papermaking thiab roj drilling.

HEC feem ntau suav hais tias muaj kev nyab xeeb rau kev siv tshuaj pleev ib ce thiab lwm yam khoom.Nws tsis paub tias yuav ua mob rau tib neeg, tsiaj txhu, lossis ib puag ncig.Qhov tseeb, nws feem ntau yog siv los ua stabilizer, thickener, thiab emulsifier hauv ntau cov khoom.

Kev nyab xeeb ntawm HEC tau raug soj ntsuam los ntawm Cosmetic Ingredient Review (CIR) Expert Panel, uas yog ib lub vaj huam sib luag ntawm cov kws paub txog kev ywj pheej uas ntsuas kev nyab xeeb ntawm cov khoom xyaw kom zoo nkauj.CIR Kws Tshaj Lij Vaj Huam Sib Luag tau xaus lus tias HEC muaj kev nyab xeeb rau kev siv tshuaj pleev ib ce, yog tias nws yog siv hauv qhov ntau ntawm 0.5% lossis tsawg dua.

Tsis tas li ntawd, European Union Pawg Saib Xyuas Kev Tshawb Fawb Txog Kev Nyab Xeeb Kev Noj Qab Haus Huv (SCCS) tau soj ntsuam kev nyab xeeb ntawm HEC thiab xaus lus tias nws muaj kev nyab xeeb rau kev siv tshuaj pleev ib ce, yog tias nws tau siv ntau dua 0.5% lossis tsawg dua.

Txawm hais tias nws feem ntau lees paub txog kev nyab xeeb, muaj qee qhov kev pheej hmoo cuam tshuam nrog kev siv HEC.Piv txwv li, qee qhov kev tshawb fawb tau qhia tias HEC tuaj yeem ua rau khaus ntawm qhov muag, tawv nqaij, thiab ua pa.Tsis tas li ntawd, HEC tuaj yeem ua rau muaj kev fab tshuaj rau qee tus neeg.
