HEC irasanzwe?

HEC ntabwo ari ibicuruzwa bisanzwe. Ni polymer synthique ikomoka kuri selile, ikaba isanzwe ibaho polysaccharide iboneka mubihingwa. Hydroxyethyl selulose HEC ni polymer yamazi yamazi akoreshwa mubikorwa bitandukanye, harimo nkibibyimba, emulisiferi, stabilisateur, hamwe nu guhagarika akazi.

HEC ikorwa no gukora selile hamwe na okiside ya Ethylene, imiti ikomoka kuri peteroli. Iyi reaction ikora polymer ifite hydrophilique (ikunda amazi), ituma ishonga mumazi. HEC ni ifu yera, itemba yubusa idafite impumuro nziza kandi itaryoshye. Ntabwo yaka kandi irahagaze hejuru yubushyuhe bwinshi nurwego rwa pH.

HEC ikoreshwa mu nganda zitandukanye, zirimo ibiryo, imiti, amavuta yo kwisiga, n'ibicuruzwa byita ku muntu. Mu biryo, ikoreshwa nkibyimbye, emulisiferi, na stabilisateur. Muri farumasi, ikoreshwa nkibikoresho bihagarika na tablet binder. Mu mavuta yo kwisiga hamwe nibicuruzwa byawe bwite, bikoreshwa nkibyimbye kandi bigahinduka.

Muri rusange HEC ifatwa nkaho ifite umutekano mu gukoresha ibiryo, imiti, no kwisiga. Yemerewe gukoreshwa muri Amerika no mu Burayi, kandi yashyizwe ku rutonde rwa FDA rusanzwe ruzwi nk'umutekano (GRAS).

HEC ntabwo ari ibicuruzwa bisanzwe, ariko nibintu byizewe kandi byiza bikoreshwa cyane mubikorwa byinshi. Nibintu byingenzi mubicuruzwa byinshi, kandi byinshi bihindura bituma iba ingirakamaro kubintu byinshi.
