Sodium wosungunuka m'madzicarboxymethyl cellulosemethyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, hydroxyethyl cellulose ndi ethyl cellulose yosungunuka ndi mafuta zonse zimagwiritsidwa ntchito ngati zomatira, zosungunuka, zinthu zotulutsira zomwe zimagwiritsidwa ntchito pokonzekera pakamwa, zopangira filimu, zinthu zopangira makapisozi ndi zinthu zoyimitsa zimagwiritsidwa ntchito muzinthu zopangira mankhwala. Poyang'ana padziko lonse lapansi, makampani angapo akunja (Shin-Etsu Japan, Dow Wolfe ndi Ashland Cross Dragon) apeza msika waukulu wamtsogolo wa cellulose yamankhwala ku China, mwina kuwonjezera kupanga kapena kuphatikiza, ndipo awonjezera khama lawo pantchitoyi. Dow Wolfe yalengeza kuti ilimbitsa chidwi chake pakupanga, zosakaniza ndi kufunikira kwa msika wokonzekera mankhwala waku China, ndipo kafukufuku wake wogwiritsidwa ntchito adzayesetsanso kuyandikira msika. Dow Chemical Wolff Cellulose Division ndi Colorcon Corporation ku United States akhazikitsa mgwirizano wokhazikika komanso wolamulidwa padziko lonse lapansi, wokhala ndi antchito oposa 1,200 m'mizinda 9, mabungwe 15 azinthu ndi makampani 6 a GMP, ndipo akatswiri ambiri ofufuza omwe amagwiritsidwa ntchito amatumikira makasitomala m'maiko pafupifupi 160. Ashland ili ndi malo opangira zinthu ku Beijing, Tianjin, Shanghai, Nanjing, Changzhou, Kunshan ndi Jiangmen, ndipo yayika ndalama m'malo atatu ofufuza zaukadaulo ku Shanghai ndi Nanjing.
Malinga ndi ziwerengero kuchokera patsamba lawebusayiti la China Cellulose Association, mu 2017, kupanga kwa cellulose ether m'nyumba kunali matani 373,000, ndipo kuchuluka kwa malonda kunali matani 360,000. Mu 2017, kuchuluka kwenikweni kwa malonda a ionic CMC kunali matani 234,000, kuwonjezeka kwa 18.61% pachaka, komanso kuchuluka kwa malonda a non-ionic.CMCinali matani 126,000, kuwonjezeka kwa 8.2% pachaka. Kuwonjezera pa HPMC (kalasi ya zipangizo zomangira), zinthu zopanda ma ionic, HPMC (kalasi ya mankhwala),HPMC(gulu la chakudya),HEC, HPC, MC, HEMC, ndi zina zotero zagonjetsa izi ndipo kupanga ndi kugulitsa kwawo kwapitirira kuwonjezeka. Cellulose ether yakunyumba yakula mofulumira kwa zaka zoposa khumi, ndipo zotsatira zake zakhala zoyamba padziko lonse lapansi. Komabe, zinthu za makampani ambiri a Cellulose ether zimagwiritsidwa ntchito makamaka m'magawo apakati ndi otsika amakampani, ndipo mtengo wowonjezera si wokwera.
Pakadali pano, mabizinesi ambiri am'nyumba okhala ndi cellulose ether ali munthawi yofunika kwambiri yosinthira ndi kukweza. Ayenera kupitiliza kuwonjezera kafukufuku wazinthu ndi chitukuko, kupititsa patsogolo mitundu yazinthu mosalekeza, kugwiritsa ntchito bwino China, msika waukulu kwambiri padziko lonse lapansi, ndikuwonjezera khama lokulitsa misika yakunja, kuti mabizinesi athe kumaliza kusintha ndi kukweza mwachangu, kulowa m'munda wapakati komanso wapamwamba wamakampani, ndikukwaniritsa chitukuko chabwino komanso chobiriwira.
