Hydroxyethyl cellulose
Yana da polymer mai narkewa wanda ba na ionic ba, fari ko ɗan rawaya, foda mai sauƙi, mara wari da rashin ɗanɗano, mai narkewa a cikin ruwan sanyi da ruwan zafi, kuma adadin narkarwar yana ƙaruwa tare da haɓakar zafin jiki. Insoluble a cikin kwayoyin kaushi.
Kaddarorin nahydroxyethyl cellulose:
1. HEO yana narkewa a cikin ruwan zafi ko sanyi, kuma ba ya yin hazo a babban zafin jiki ko tafasa, don haka yana da nau'i mai yawa na solubility da danko, da kuma rashin zafi.
2. Ba-ionic kanta ba zai iya zama tare da nau'i-nau'i na sauran polymers masu narkewa da ruwa, surfactants da salts, kuma yana da kyau mai kyau na colloidal thickener don high-concentration electrolyte mafita.
3. Ƙarfin ajiyar ruwa ya ninka sau biyu kamar na methyl cellulose, kuma yana da mafi kyawun tsarin tafiyar da ruwa.
4. Idan aka kwatanta da gane methyl cellulose da hydroxypropyl methyl cellulose, da dispersing ikon HEC ne mafi muni, amma m colloid ikon ne mafi karfi.
