The number of ethyl groups can vary depending on the manufacturer. It is mainly used as a thin-film coating material for coating paper, vitamin and medical pills, and for thickeners in cosmetics and in industrial processes. Food grade ethyl cellulose is one of few non-toxic films and thickeners which are not water soluble. This property allows it to be used to safeguard ingredients from water.[1] Ethyl cellulose is also used as a food additive as an emulsifier (E462). See also
