Hydroxyethyl cellulose (HEC) fari ne ko rawaya mai haske, mara wari, mara guba, fibrous ko foda mai ƙarfi wanda aka shirya ta hanyar etherification na alkaline cellulose da ethylene oxide (ko chlorohydrin). Cellulose ethers masu narkewa marasa ionic. Saboda HEC yana da kyawawan halaye na kauri, dakatarwa, warwatsewa, emulsifying, haɗawa, ƙirƙirar fim, kare danshi da samar da colloids masu kariya, an yi amfani da shi sosai a binciken mai, shafi, gini, magani da abinci, yadi, yin takarda da polymers. Polymerization da sauran filayen. Hydroxyethyl cellulose ba shi da tabbas a yanayin zafi da matsin lamba na yau da kullun, yana guje wa danshi, zafi, da zafin jiki mai yawa, kuma yana da kyakkyawan narkewar gishiri ga dielectrics. Maganin ruwa nasa an yarda ya ƙunshi babban adadin gishiri kuma yana da karko.
