Canned food industry high substitution degree of CMC for ice cream on the surface of the instant thickening agent of beer foam stabilizer, widely used in printing paper coating ceramic oil pesticide processing the food industry, such as sizing agent thickener emulsifiers emulsify stabilizer adhesives film-former, etc
the melting point is 300°C

Commonly used sodium white flocculent powder, odourless, tasteless, non-toxic, soluble in water, the formation of cellophane tape, microemulsions, thermal stability of solution is neutral light has the water absorbability cresol such as ethanol, acetone chloroform benzene insoluble in acid, soluble in alcohol ether with carboxymethyl cellulose derivatives, substituting group treated with sodium hydroxide to form alkali cellulose, again with monochloroacetic acid reaction of cellulose was made by the hydroxyl groups of glucose units have 3 can be replaced, so can obtain different degree of substitution of products per 1 g dry weight guide people tendency carboxymethyl, insoluble in water, dilute acid, but can swelling, used in ion exchange chromatography carboxymethyl pKa of about 4 in the pure water, in 0.5 mol/L NaCl is about 3.5, is a weak acid cation exchanger, usually to pH4
