Hydroxyethylcellulose (HEC) ni selile ya elegitoronike ya elegitoronike ikoreshwa cyane mu nganda zitandukanye. HEC ikomoka kuri selile isanzwe kandi ihindurwa kugira amatsinda ya hydroxyethyl kumugongo wa selile. Ihinduka rituma HEC ishonga cyane mumazi nandi mashanyarazi ya polar, bigatuma iba polymer nziza kubikorwa bitandukanye.
Bumwe mu buryo bwibanze bukoreshwa na HEC ni nkibyimbye kandi bifata mubicuruzwa bitandukanye byabaguzi ninganda. HEC isanzwe ikoreshwa mubisiga no kwisiga kugiti cyawe nka shampo, amavuta yo kwisiga hamwe nu menyo yinyo kugirango itange ubwiza no gutuza. Irakoreshwa kandi mu gusiga amarangi, gutwikira hamwe no gufatira hamwe kugirango itange ibintu bifata neza kandi irusheho kurwanya ubushuhe.
HEC ni inyubako inyuranye yibicuruzwa kubera ubushobozi bwayo bwo kongera ububobere muri sisitemu ishingiye kumazi bitagize ingaruka zikomeye kubindi bicuruzwa. Mugushyiramo HEC kubicuruzwa, abayikora barashobora guhuza ubunini, imiterere nuburyo buhoraho bwibicuruzwa byabo kugirango bahuze ibyifuzo byabaguzi nibisabwa ninganda.
Ubundi buryo bukoreshwa bwa HEC ni muruganda rwa farumasi. HEC ni ibintu bisanzwe mubicuruzwa byinshi bikoreshwa mu bya farumasi, harimo ibinini, capsules, hamwe na sisitemu yo gutanga imiti. Bitewe nubushobozi bwabo bwo guhindura imvugo nuburyo bwo kubyimba kumiterere ya dosiye, HEC irashobora kongera bioavailable yibintu bikora kandi ikanagenzura kugenzura irekurwa ryibiyobyabwenge. HEC nayo ikoreshwa mugutezimbere emulisiyo no guhagarikwa mumiti ya farumasi.
Mu nganda z’ibiribwa, HEC ikoreshwa nkibyimbye na stabilisateur mubicuruzwa bitandukanye byibiribwa, birimo isosi, imyambaro n’ibikomoka ku mata. HEC ni ibintu byizewe, karemano byemewe gukoreshwa mubiribwa ninzego zishinzwe kugenzura isi. Ikoreshwa kandi nk'igisimbuza ibinure mu biribwa birimo amavuta make, itanga imiterere isa na umunwa ku bicuruzwa byuzuye amavuta.
HEC ikoreshwa kandi mubikorwa byubwubatsi nkibibyimbye kandi bihuza ibicuruzwa bya sima nka grout, minisiteri hamwe na adhesives. Imiterere ya thixotropique ya HEC ituma iba ikintu cyiza kubicuruzwa, ibemerera kuguma mu mwanya wabo no kwirinda kugabanuka cyangwa gutura. HEC ifite uburyo bwiza bwo gufatira hamwe no kurwanya amazi, bigatuma iba ingenzi mu kurinda amazi no gufunga ibicuruzwa.
Hydroxyethyl selulose ni ionic soluble selulose ether hamwe nibikorwa byinshi mubikorwa bitandukanye. HEC ni ibintu byinshi kandi byingenzi mubicuruzwa byinshi byabaguzi ninganda, bitanga umutekano muke, ubwiza, no kugenzura ibiyobyabwenge. HEC ni ikintu gisanzwe, gifite umutekano kandi cyangiza ibidukikije cyemewe gukoreshwa n’ibihugu byinshi ku isi. Imiterere yihariye kandi ihindagurika ituma HEC iba ingenzi mubicuruzwa n'inganda nyinshi.
