Ethyl cellulose polymers are organo-soluble thermoplastics used widely in pharmaceutical industries. Ethyl Cellulose polymers are one of the few polymers that are water insoluble and has pharmaceutical application. Ethyl Cellulose products are essentially tasteless, odourless, non- caloric and physiologically inert.
They form a tough film at low concentrations.

APPLICATION
- 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.
- Ethyl cellulose is commonly used as a coating material for tablets and capsules, as it provides a protective barrier that prevents the active ingredients from being released too quickly in the digestive system. Ethyl Cellulose is also used as a binder, thickener, and stabilizer in a variety of food, cosmetic, and pharmaceutical products.
