Celdoulose Ether e na le hydrophphilica e matla haholo, e tlisoang ke palo e kholo ea hydroxyl (----oh) lihlopha ka sebopeho sa eona sa lilokek'hule. Lihlopha tsa hydroyl habonolo li theha li-hydrogen litlamo tse nang le limolek'hule tsa metsi, li lumellang cellulose hore li monya le ho boloka metsi a mangata. Tharollo e telele, limolek'hule tsa limooneulose li ka baka motsamao oa marang-rang a likarolo tse tharo, ka ho fokotsa sekhahla sa metsi, ka ho etsa joalo, ho ntlafatsa thepa ea metsi.
Cellulose Ether o ka fetola sekhahla sa eona sa ho lokolloa ka tlasa mocheso o fapaneng le maemo a mongobo. Ka mohlala, ka tikoloho e phahameng ea mocheso, palo ea mocheso, ether ea khoelsulose e ka fetola sekhahla sa metsi ka ho fetola pono ea eona, ho thibela ho bakoang le tahlehelo ea metsi.
