Ingabe i-hydroxyethylcellulose iyingozi?

IHydroxyethylcellulose (HEC) iyi-polymer yokwenziwa etholakala ku-cellulose, i-polysaccharide yemvelo etholakala ezitshalweni.I-HEC iyinto engenabuthi, engacasuli, futhi engeyona i-allergenic esetshenziswa emikhiqizweni ehlukahlukene, okuhlanganisa izimonyo, imithi, nemikhiqizo yokudla.Ibuye isetshenziswe emisebenzini yezimboni, njengokwenza amaphepha kanye nokubhola uwoyela.

I-HEC ngokuvamile ibhekwa njengephephile ukusetshenziswa ezimonyoni nakweminye imikhiqizo.Akwaziwa ukuthi iyingozi kubantu, ezilwaneni noma endaweni ezungezile.Eqinisweni, isetshenziswa kaningi njenge-stabilizer, thickener, kanye ne-emulsifier emikhiqizweni eminingi.

Ukuphepha kwe-HEC kuye kwahlolwa yi-Cosmetic Ingredient Review (CIR) Expert Panel, okuyiphaneli yochwepheshe abazimele besayensi abahlola ukuphepha kwezithako zezimonyo.Iphaneli Yochwepheshe be-CIR iphethe ngokuthi i-HEC iphephile ukuthi isetshenziswe ezimonyoni, inqobo nje uma isetshenziswa ekugxiliseni okungu-0.5% noma ngaphansi.

Ngaphezu kwalokho, i-European Union's Scientific Committee on Consumer Safety (SCCS) ihlole ukuphepha kwe-HEC futhi yaphetha ngokuthi iphephile ukuthi isetshenziswe ezimonyoni, inqobo nje uma isetshenziswa ekugxiliseni okungu-0.5% noma ngaphansi.

Naphezu kokuphepha kwayo okuqashelwa ngokuvamile, kunezingozi ezingaba khona ezihlobene nokusetshenziswa kwe-HEC.Ngokwesibonelo, olunye ucwaningo luye lwasikisela ukuthi i-HEC ingase icasule amehlo, isikhumba, nesimiso sokuphefumula.Ngaphezu kwalokho, i-HEC ingabangela ukungezwani komzimba kwabanye abantu.

Sengiphetha, i-HEC ngokuvamile ibhekwa njengephephile ukusetshenziswa kwezimonyo neminye imikhiqizo.Nokho, kubalulekile ukuqaphela izingozi ezingase zibe khona ezihlobene nokusetshenziswa kwayo.Kubalulekile futhi ukulandela imihlahlandlela yokuphepha esungulwe i-CIR Expert Panel kanye ne-SCCS lapho usebenzisa i-HEC ezimonyoni nakweminye imikhiqizo.
