Ethyl methyl cellulose is a thickener, vegetable gum, foaming agent and emulsifier.

Its E number is E465.

Description

Chemically, it is a derivative of cellulose with ethyl and methyl groups attached by ether linkages.^{[citation needed]}

It can be prepared by treatment of cellulose with dimethyl sulfate and ethyl chloride in the presence of an alkali.
