Hydroxyethyl selulose yangiza?

Hydroxyethyl selulose (HEC) ni polymer idafite ionic, amazi-elegitoronike ikomoka kuri selile, nikintu gisanzwe kiboneka murukuta rw'utugingo ngengabuzima. Ifite uburyo butandukanye bwo gukoresha mubikorwa bitandukanye, harimo imiti, amavuta yo kwisiga, ibiryo, nubwubatsi, cyane cyane kubyimbye, guhuza, kwigana, no gutuza. Ariko, nkibintu byose, umutekano wa HEC biterwa nikoreshwa ryihariye, kwibanda, no kugaragara.

Muri rusange, HEC ifatwa nkumutekano kugirango ikoreshwe mu nganda zavuzwe haruguru iyo ikoreshejwe mumabwiriza yihariye. Ariko, hariho ibitekerezo bimwe ugomba kwitaho kubijyanye n'umutekano wacyo:

Kwinjiza mu kanwa: Mugihe muri rusange HEC izwi nkumutekano mukoresha mubiribwa no gukoresha imiti, gufata cyane HEC bishobora gutera uburibwe bwa gastrointestinal. Ariko, birakwiye ko tumenya ko HEC idakoreshwa muburyo butaziguye kandi mubisanzwe iboneka mubicuruzwa biri hasi cyane.

Gukangurira uruhu: Mubintu byo kwisiga no kwita kubantu kugiti cyabo, HEC ikunze gukoreshwa nkibyimbye, binder, hamwe na stabilisateur muburyo bwa cream, amavuta yo kwisiga, na shampo. Mubisanzwe bifatwa nkumutekano kugirango ukoreshwe neza, ariko abantu bamwe bashobora kugira uburibwe bwuruhu cyangwa allergie reaction kuri HEC, cyane cyane niba bafite ibyiyumvo byabanje kubaho kubikomoka kuri selile.

Kurakara kw'amaso: Rimwe na rimwe, ibicuruzwa birimo HEC, nk'ibitonyanga by'amaso cyangwa ibisubizo bya lens ibisubizo, bishobora gutera uburakari ku jisho, cyane cyane iyo ibicuruzwa byanduye cyangwa bikoreshejwe nabi. Abakoresha bagomba guhora bakurikiza amabwiriza yo gukoresha no gushaka ubuvuzi niba uburakari bubaye.

Gukangura Ubuhumekero: Guhumeka umukungugu wa HEC cyangwa aerosole birashobora gutera uburakari cyangwa gukangurira abantu bamwe, cyane cyane abafite ubuhumekero bwabayeho mbere cyangwa ibyiyumvo byangiza ikirere. Gufata neza no guhumeka neza bigomba gukorwa mugihe ukorana nifu ya HEC.

Ingaruka ku bidukikije: Mu gihe HEC ubwayo ishobora kwangirika kandi ikangiza ibidukikije, inzira yo kubyaza umusaruro no kujugunya ibicuruzwa birimo HEC bishobora kugira ingaruka ku bidukikije. Hagomba gushyirwaho ingufu kugirango hagabanuke imyanda n’umwanda ujyanye no gukora, gukoresha, no kujugunya ibicuruzwa bishingiye kuri HEC.

Inzego zishinzwe kugenzura ibigo by’Amerika bishinzwe ibiribwa n’ibiyobyabwenge (FDA), Ikigo cy’Uburayi gishinzwe umutekano w’ibiribwa (EFSA), hamwe n’itsinda ry’impuguke za Cosmetic Ingredient Review (CIR) basuzumye umutekano wa HEC kandi basanga ari umutekano ku byo bigenewe gukoreshwa mu gihe cyagenwe kwibanda. Nyamara, ni ngombwa ko abayikora bubahiriza amabwiriza ngenderwaho kandi bakemeza ubuziranenge n'umutekano by'ibicuruzwa byabo binyuze mu gupima no gufata ingamba zo kugenzura ubuziranenge.

hydroxyethyl selulose isanzwe ifatwa nkumutekano kugirango ikoreshwe mu nganda zitandukanye iyo ikoreshejwe neza kandi mubuyobozi bwihariye. Nyamara, kimwe n’ibintu byose bya shimi, gufata neza, kubika, no kujugunya bigomba gukurikizwa kugirango hagabanuke ingaruka zishobora guteza ubuzima bwabantu n’ibidukikije. Abantu bafite impungenge zihariye kuri HEC cyangwa ibicuruzwa birimo HEC bagomba kugisha inama inzobere mu buvuzi cyangwa inzego zishinzwe kugenzura inama kugiti cyabo.
