Kodi hydroxyethyl cellulose ndi yowopsa?

Hydroxyethylcellulose (HEC) ndi polima opangidwa kuchokera ku cellulose, polysaccharide yachilengedwe yomwe imapezeka muzomera.HEC ndi zinthu zopanda poizoni, zosakwiyitsa, komanso zopanda allergenic zomwe zimagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikizapo zodzoladzola, mankhwala, ndi zakudya.Amagwiritsidwanso ntchito m'mafakitale, monga kupanga mapepala ndi kubowola mafuta.

HEC nthawi zambiri imawonedwa ngati yotetezeka kuti igwiritsidwe ntchito muzodzoladzola ndi zinthu zina.Sizidziwika kuti n’njovulaza anthu, nyama, kapena chilengedwe.Ndipotu, nthawi zambiri amagwiritsidwa ntchito ngati stabilizer, thickener, ndi emulsifier muzinthu zambiri.

Chitetezo cha HEC chayesedwa ndi Cosmetic Ingredient Review (CIR) Expert Panel, yomwe ndi gulu la akatswiri odziimira okhaokha omwe amayesa chitetezo cha zodzoladzola zodzikongoletsera.Bungwe la CIR Expert Panel linanena kuti HEC ndi yotetezeka kuti igwiritsidwe ntchito muzodzoladzola, pokhapokha ngati ikugwiritsidwa ntchito m'magulu a 0.5% kapena osachepera.

Kuphatikiza apo, European Union's Scientific Committee on Consumer Safety (SCCS) yawunika chitetezo cha HEC ndipo idatsimikiza kuti ndi yotetezeka kuti igwiritsidwe ntchito muzodzola, pokhapokha ngati ikugwiritsidwa ntchito mozungulira 0.5% kapena kuchepera.

Ngakhale kuti ndi chitetezo chodziwika bwino, pali zoopsa zina zomwe zingagwirizane ndi kugwiritsa ntchito HEC.Mwachitsanzo, kafukufuku wina wasonyeza kuti HEC ikhoza kukwiyitsa maso, khungu, ndi kupuma.Kuphatikiza apo, HEC imatha kuyambitsa kuyamwa kwa anthu ena.

Pomaliza, HEC nthawi zambiri imawonedwa ngati yotetezeka kuti igwiritsidwe ntchito muzodzola ndi zinthu zina.Komabe, ndikofunikira kudziwa zoopsa zomwe zingachitike ndikugwiritsa ntchito kwake.Ndikofunikiranso kutsatira malangizo otetezedwa okhazikitsidwa ndi CIR Expert Panel ndi SCCS mukamagwiritsa ntchito HEC muzodzoladzola ndi zinthu zina.
