Carboxymethyl ethoxy ethyl cellulose

Carboxymethyl ethoxy ethyl cellulose (CMEC) is a modified cellulose derivative that is widely used in the food, pharmaceutical, and cosmetic industries. It is made by reacting ethyl cellulose with sodium chloroacetate and then further reacting with sodium hydroxide to form carboxymethyl groups. The resulting product is then treated with ethylene oxide to introduce ethoxy and ethyl groups.

CMEC is used as a thickener, stabilizer, and emulsifier in various food products such as sauces, dressings, and beverages. It is also used in pharmaceuticals as a binder and disintegrant in tablets and capsules. In cosmetics, CMEC is used as a thickener and emulsifier in lotions and creams.

CMEC is a white to off-white powder that is soluble in water and organic solvents. It has good thermal stability and can withstand high temperatures and acidic conditions. CMEC is generally considered safe for use in food and pharmaceutical products, and it is approved by regulatory agencies such as the FDA and the European Food Safety Authority.
