Hydroxyethyl selile ni iki?

Hydroxyethyl selulose (HEC) ni polimeri ikabura amazi ikomoka kuri selile, polisikaride isanzwe iboneka mubihingwa. HEC yashizweho binyuze muguhindura selile yongeyeho amatsinda ya hydroxyethyl, afatanye na glucose yibice bya molekile ya selile. Ihinduka rihindura imiterere ya selile kandi ikagira akamaro mubikorwa bitandukanye, nko mubiribwa, amavuta yo kwisiga, na farumasi.

HEC ni polymer ihindagurika cyane, ifite uburemere bwa molekuline hamwe na dogere zo gusimbuza, bigena imiterere yabyo, nko gukomera kwayo, kwiyegeranya, hamwe na gelation. Urwego rwo gusimburwa ni igipimo cyumubare wamatsinda ya hydroxyethyl yometse kuri buri gice cya glucose ya molekile ya selile, kandi irashobora kuva kuri 1 kugeza kuri 3, hamwe nimpamyabumenyi zisumbuye zerekana umubare munini wamatsinda ya hydroxyethyl.

HEC ikoreshwa mubicuruzwa bitandukanye nkibibyimbye, stabilisateur, na binder. Irashobora gukoreshwa kugirango wongere ubwiza bwimyunyu ngugu, kunoza imiterere numunwa wibicuruzwa byibiribwa, no kuzamura ituze rya emulisiyo. Mu nganda zimiti, HEC ikoreshwa nkububiko bwibinini, nkibibyimbye byibanze, kandi nkumukozi urekura uburyo bwo gutanga ibiyobyabwenge.

Imwe mu miterere yingenzi ya HEC nubushobozi bwayo bwo gukora geles mumazi. Iyo HEC ishonga mumazi, irashobora gukora gel binyuze munzira izwi nka hydration. Inzira ya gelation iterwa nurwego rwo gusimburwa, uburemere bwa molekile, hamwe nubushakashatsi bwa HEC mubisubizo. Inzira ya gelation ya HEC irashobora kugenzurwa binyuze muguhindura ibipimo, bigatuma bigira akamaro mubikorwa bitandukanye.

HEC ikunze gukoreshwa mu nganda zibiribwa nkibibyimbye kandi bigahindura ibicuruzwa nka sosi, imyambarire, hamwe nisupu. Irashobora kunoza imiterere numunwa wibicuruzwa, kandi bikongerera umutekano mugihe. HEC irashobora kandi gukoreshwa muguhagarika emulisiyo, nka mayoneze, mukurinda gutandukanya ibice byamavuta namazi.

Mu nganda zo kwisiga, HEC ikoreshwa mubintu byinshi byita ku muntu ku giti cye, harimo shampo, kondereti, amavuta yo kwisiga, hamwe na cream. HEC irashobora kunoza imiterere no guhuza ibyo bicuruzwa, ikongerera imiterere yubushuhe, kandi igatanga ibyiyumvo byoroshye, bya velveti. Irashobora kandi guhagarika emulisiyo muburyo bwo kwisiga no gufasha kwirinda gutandukanya ibice byamavuta namazi.

Mu nganda zimiti, HEC ikoreshwa nkumuhuza mugutegura ibinini kugirango ibinini bya tablet bikomeze guhurizwa hamwe. Irakoreshwa kandi nkibyimbye kugirango ibe ifatika, aho ishobora kongera ububobere nubwitonzi bwamavuta namavuta. Byongeye kandi, HEC ikoreshwa nkumukozi urekura-sisitemu yo gutanga ibiyobyabwenge, aho ishobora kugenzura igipimo cy’ibiyobyabwenge bisohoka mu mubiri.

HEC ifite imitungo myinshi idasanzwe ituma polymer yingirakamaro mubikorwa bitandukanye. Bimwe muri ibyo bintu birimo:

Amazi meza-HEC: HEC irashobora gushonga cyane, bigatuma byoroha kwinjiza mumazi ashingiye kumazi.

Ibidafite uburozi na biocompatible: HEC muri rusange ifatwa nkibikoresho byizewe kandi biocompatible, bigatuma bigira akamaro mubikorwa bya farumasi no kwisiga.

Ibinyuranye: HEC ni polymer ihindagurika cyane ishobora gukoreshwa muburyo butandukanye bitewe nubushobozi bwayo bwo gukora geles no kumenyera kurwego rutandukanye rwo gusimbuza nuburemere bwa molekile.

Mu gusoza, hydroxyethyl selulose ni polymer-yamazi yamazi ikomoka kuri selile ikoresheje kongeramo amatsinda ya hydroxyethyl.
