Hydroxyethyl Cellulose CAS 9004-62-0
Hydroxyethyl cellulose ni ifu y’umweru cyangwa umuhondo woroshye, idahumanya, nta buryohe, kandi yoroshye gushonga mu mazi. Ntishobora gushonga mu bintu bisanzwe by’umwimerere. Ifite imiterere yo gukomera, guhagarika, gufatanya, gushonga, gukwirakwiza no kubika ubushuhe. Ibisubizo bifite ubushuhe butandukanye birashobora gutegurwa. Ifite uburyo bwiza bwo gushonga mu munyu mu buryo budasanzwe muri electrolytes. Hydroxyethyl cellulose ni ifu y’umweru cyangwa umuhondo woroshye idafite impumuro, uburyohe, kandi yoroshye gutemba. Irashonga mu mazi akonje n’ashyushye, kandi muri rusange ntishobora gushonga mu bintu byinshi by’umwimerere. Ubushuhe buhinduka gato iyo pH iri hagati ya 2-12, ariko ubushuhe bugabanuka burenga ubwo bwoko.

1. Hydroxyethyl cellulose (HEC) ni ether ya cellulose idafite ionic isomba ifite ubunini bwiza, isunika, ikwirakwira, ihuza, ifatana, ikora firime, irinda ubushuhe n'imiterere yo kurinda colloid. Bitewe n'imiterere yayo yihariye y'umubiri n'imiti, HEC ikoreshwa cyane mu nzego nyinshi, harimo ariko ntigarukira gusa ku gucukura amavuta, gusiga irangi, kubaka, ibiribwa bya farumasi, imyenda, gukora impapuro no gupima polimeri.
2. Mu rwego rw'imiti, uretse kuba ikomeza ubushyuhe no kurinda, hydroxyethyl cellulose ifite ingaruka zo koroshya, gukurura amazi, kurwanya gusaza, gusukura uruhu no gukuraho melanin. Ikwiriye gukorwamo ibitonyanga mu maso, spray zo mu mazuru, imiti yo kunywa, nibindi. Ishobora kongera ubukana bw'umuti, kongera umuvuduko w'umuti mu mubiri, no kongera ubuziranenge bw'umuti kugira ngo wirinde ko umuti ubora cyangwa ushonga.
3. Mu nganda zikora amavuta yo kwisiga, HEC ikoreshwa cyane mu gukora shampoo, conditioner, cream, lotion n'ibindi bikoresho. Ishobora guhindura ubukana n'imiterere y'amavuta yo kwisiga kugira ngo yorohere kuyashyira no kuyakurura. Ariko kandi, ifite ubushobozi bwo koroshya, ishobora gufunga ubushuhe, kandi ikarinda uruhu kuma no kwangirika.
4. Byongeye kandi, hydroxyethyl cellulose ikoreshwa cyane cyane nk'ikintu gikomeza ubushyuhe, ibara n'uburyohe mu nganda z'ibiribwa, bishobora kongera ubushyuhe n'imiterere y'ibiryo no kunoza uburyohe n'ubwiza bw'ibiryo. Ishobora kandi gukoreshwa nk'ikintu gitera imbaraga no gushimangira ibiryo kugira ngo hirindwe ko ibiryo bitandukana cyangwa ngo bigwe.
5. Ku bijyanye n'ubushyuhe n'ubukana bwa hydroxyethyl cellulose, kubera ko iri mu itsinda rya ether ritari ionic cellulose, ntabwo ari aside cyangwa alkaline. Formula yayo ya shimi ni (C2H6O2)n, ifite ubushobozi bwo gushonga neza, kuguma neza no gukomera, kandi igira uruhare runini mu nzego zitandukanye zo kuyikoresha.
