Ether cellulose na-abụghị ionic bụ ihe dị mkpa nke ụlọ ọrụ ihe owuwu na ụlọ ọrụ mkpuchi chọrọ. Ugbu a, n'okpuru mmụba na-aga n'ihu na uru mmepụta nke ụlọ ọrụ owuwu ụlọ na mmụba na-aga n'ihu nke ahịa mkpuchi, ọchịchọ ahịa ya na-aga n'ihu na-eto.
Cellulose ether na-ezo aka na ngwakọta polima nwere nhazi ether nke e ji cellulose mee. Ọ na-agbaze na mmiri, na-agbaze na mmiri alkali na ihe mgbaze organic, ma nwee thermos-plasticity.

Dịka njirimara ionization dị iche iche si dị, enwere ike kewaa cellulose ethers n'ime ụdị atọ: non-ionic cellulose ethers, ionic cellulose ethers, na mixed cellulose ethers.
Ma e jiri ya tụnyere ionic na agwakọta cellulose ethers, cellulose ethers ndị na-abụghị ionic nwere ike iguzogide okpomọkụ ka mma, iguzogide nnu, ịgbaze mmiri, nkwụsi ike kemịkalụ, ọnụ ahịa dị ala na usoro tozuru oke, enwere ike iji ha dị ka ihe na-emepụta fim, ihe ndị na-eme ka ihe dị arọ, ihe ndị na-eme ka mmiri dịgide, ihe ndị na-ejide mmiri, ihe ndị na-eme ka ihe sie ike, ihe ndị na-eme ka ihe sie ike na ihe ndị ọzọ na-eme ka ihe dị n'ime ụlọ, ihe mkpuchi, kemịkalụ kwa ụbọchị, nri, ákwà na ubi ndị ọzọ, ahịa ahụ nwekwara nnukwu atụmanya maka mmepe. Ugbu a, ihe ndị na-abụghị ionic cellulose ethers ndị a na-ahụkarị gụnyere hydroxypropyl methyl (HPMC), hydroxyethyl methyl (HEMC), methyl (MC), hydroxypropyl (HPC), hydroxyethyl (HEC) na ndị ọzọ.
Nonionic cellulose ether bụ ihe kemịkal dị mkpa nke ụlọ ọrụ ihe owuwu na ụlọ ọrụ mkpuchi chọrọ.
