Ngaba i-hydroxyethylcellulose iyingozi?

IHydroxyethylcellulose (HEC) yipolymer eyenziweyo evela kwi-cellulose, i-polysaccharide yendalo efumaneka kwizityalo. I-HEC yinto engeyiyo ityhefu, i-non-irritation, kunye ne-non-allergenic material esetyenziswa kwiimveliso ezahlukeneyo, kubandakanywa izimonyo, i-pharmaceuticals, kunye nemveliso yokutya. Ikwasetyenziswa nakwimizi-mveliso, njengokwenza iphepha kunye nokugrumba ioli.

I-HEC ngokuqhelekileyo ithathwa njengekhuselekile ukusetyenziswa kwizinto zokuthambisa kunye nezinye iimveliso. Akwaziwa njengeyingozi ebantwini, kwizilwanyana nakwimekobume. Enyanisweni, isoloko isetyenziswa njenge-stabilizer, thickener, kunye ne-emulsifier kwiimveliso ezininzi.

Ukhuseleko lwe-HEC luye lwavavanywa yi-Cosmetic Ingredient Review (CIR) iPhaneli yeNgcali yeNgcali, eyiphaneli yeengcali zenzululwazi ezizimeleyo ezivavanya ukhuseleko lwezithako zokuthambisa. IPhaneli yeeNgcali ze-CIR igqibe kwelokuba i-HEC ikhuselekile ukuba ingasetyenziswa kwizinto zokuthambisa, ngaphandle kokuba isetyenziswe ekugxininiseni kwe-0.5% okanye ngaphantsi.

Ukongezelela, iKomiti yeSayensi ye-European Union yoKhuseleko loMthengi (SCCS) iye yavavanya ukhuseleko lwe-HEC kwaye yagqiba ukuba ikhuselekile ekusebenziseni izimonyo, ngaphandle kokuba isetyenziswe ekugxininiseni kwe-0.5% okanye ngaphantsi.

Ngaphandle kokhuseleko oluvunyiweyo ngokubanzi, kukho imingcipheko enokubakho enxulumene nokusetyenziswa kwe-HEC. Ngokomzekelo, uphando oluthile lucebise ukuba i-HEC inokucaphukisa amehlo, ulusu kunye nenkqubo yokuphefumula. Ukongeza, i-HEC inokubangela ukusabela komzimba kwabanye abantu.

Ukuqukumbela, i-HEC ngokuqhelekileyo ithathwa njengekhuselekile ukusetyenziswa kwizinto zokuthambisa kunye nezinye iimveliso. Nangona kunjalo, kubalulekile ukuqaphela iingozi ezinokubakho ezinxulumene nokusetyenziswa kwayo. Kwakhona kubalulekile ukulandela izikhokelo zokhuseleko ezisekwe yi-CIR Expert Panel kunye ne-SCCS xa usebenzisa i-HEC kwizinto zokuthambisa kunye nezinye iimveliso.
