Ọtụtụ ndị ọrụ anaghị ege ntị na nsogbu nke jel okpomọkụ nke hydroxypropyl methylcellulose.

Ọdịnaya nke methyl acid na-emetụta kpọmkwem na ester-akpụ akpụ ogo nke cellulose ester, na ọdịnaya nke methyl acid na-gbanwee iji chịkwaa nhazi, mmeghachi omume okpomọkụ na oge mmeghachi omume. N'otu oge ahụ, ọkwa nke ether ngwọta na-emetụta ọdịnaya nke hydroxyethyl ma ọ bụ hydroxyapatite. Ya mere, cellulose ethers na a na-emekarị elu okpomọkụ nke jel ga-adị obere mmiri.
