Ingabe i-hydroxyethyl cellulese iyingozi?

I-Hydroxyyethyl cellulose (HEC) yi-nonic, i-polymer esolulekayo yamanzi etholakala ku-cellulose ngokuguqulwa kwamakhemikhali. Isetshenziswa kakhulu kwizimboni ezahlukahlukene ezinjengezimonyo, amakhambi, ukwakhiwa kanye nokukhiqizwa kokudla ngenxa yezakhiwo zayo zokuqina, ukuzinza, kanye nokugcinwa kwamanzi. Kodwa-ke, njenganoma iyiphi into yamakhemikhali, ukuphepha kwako kuncike ekusetshenzisweni kwayo kanye nokuhlushwa.

Isingeniso seHydroxYethyl Cellulose (HEC)
I-HEC ingeyomndeni we-cellulose ether, ehlanganisa izinhlobo ezahlukene ze-cellulose decivatives ezikhiqizwe ngokuguqulwa kwamakhemikhali. Ukungezwa kwamaqembu we-hydroxyethyl kuma-molecule we-cellulose kuthuthukisa ukuzungulwa kwawo emanzini, okwenza i-hec ibe yingxenye ebalulekile ezimbonini lapho kudla khona amanzi asuselwa emanzini.

1.ProPeries we-HEC:
I-Solubinity yamanzi: I-HEC ikhombisa i-soubity ephezulu emanzini, yakha izixazululo ezicacile nezibonakalayo.
Ukuguquguquka kwe-Viscosity: Kungashintsha kakhulu ukubonakala kwezixazululo, okwenza kube yi-ejenti enhle kakhulu.
Ukuqina: I-HEC ithuthukisa ukuqina kokwakheka, ukuvimbela ukuhlukaniswa kwesigaba kanye nokwenza ngcono impilo yeshelufu.
Ukwakheka kwamafilimu: Inezakhiwo ezenziwe ngefilimu, okwenza kube wusizo ezitsheni nasezinamathiselwe.

Ukusetshenziswa kwezimboni:
Izimonyo kanye nokunakekelwa komuntu siqu: I-HEC isetshenziswa kabanzi kuma-shampoos, ama-lotion, okhilimu, nama-gels njenge-ejenti yokuqina nokuzinza.
IMITHETHO: Ithola izinhlelo zokusebenza ekumisweni kokumiswa komlomo, ukwakhiwa kwe-topical, kanye nezixazululo ze-ophthalmic ngenxa yekhono layo lokuthuthukisa ukubonana nokwenza ngcono ukuthungwa.
Ukwakhiwa: I-HEC isetshenziswa emikhiqizweni esekwe kuthusi ukwenza ngcono ukusebenza, ukugcinwa kwamanzi, kanye nokunamathela.
Imboni yokudla: Embonini yokudla, isebenza njengomuntu omkhulu, i-stabilizer, kanye ne-emulsifier emikhiqizweni efana namasoso, ukugqoka kanye nama-dessert.
Ukucatshangelwa Kwezokuphepha

Iphrofayili ye-3.Toxicity:
Ubuthi obuphansi: I-HEC ngokuvamile icatshangelwa iphephile ukuze isetshenziswe kwizicelo ezahlukahlukene.
Okungacasuli: Akucasuli esikhunjeni namehlo ekugxileni okujwayelekile.
Ukungazwisisi: I-HEC ayijwayelekile ukubangela ukusabela komzimba.

Ubungozi be-4.Potential:
Ingozi yokuphefumula: Izinhlayiya ezinhle ze-HEC zingahle zibe yingozi yokuphefumula uma ifakwe ngamanani amakhulu ngesikhathi sokuphatha noma ukucubungula.
Ukugxila Okuphezulu: Ukusetshenziswa ngokweqile noma ukufakwa kwezixazululo ezihlanganisiwe ze-HEC kungaholela ekungaphathekiseni kwesisu.
Ukungcola: Ukungcola kumalungiselelo we-HEC kungabeka ubungozi kuye ngokuya ngesimo sabo kanye nokuhlushwa kwabo.

Imithetho ye-5.FDA:
E-United States, i-Food and Drug Administration (FDA) ilawula ukusetshenziswa kwe-HEC ekudleni, emikhakheni kanye nezimonyo. Ivumela amamaki athile we-HEC ngezicelo ezihlukile ezisuselwa ekuhlolweni kokuphepha.

I-6.European Union:
E-European Union, i-HEC ilawulwa ngaphansi kokufinyelela (ukubhaliswa, ukuhlolwa, ukugunyazwa, kanye nokuvinjelwa kokusetshenziswa kwayo kwamakhemikhali), kuqinisekisa ukusetshenziswa kwayo okuphephile nokunciphisa izingozi zemvelo nezempilo.

IHydroxYethyl Cellulose (I-HEC) iyinhlangano eguquguqukayo enezicelo ezisakazekile kuyo yonke imboni ehlukahlukene. Uma isetshenziswa ngokuya ngemihlahlandlela yokulawula kanye namazinga wezimboni, iveza ubungozi obuncane kwezempilo yabantu kanye nemvelo. Kodwa-ke, njenganoma iyiphi into yamakhemikhali, ukuphathwa okufanele, ukugcinwa, kanye nezindlela zokulahla kubalulekile ukuze unciphise izingozi ezingaba khona. Sekukonke, i-HEC iyaqhubeka nokudlala indima ebalulekile ekuthuthukiseni ikhwalithi nokusebenza kwemikhiqizo eminingi ngenkathi kugcinwa iphrofayili yokuphepha enhle.
