GB 1904-2005 Standard CMC Sodium Salt Carboxymethyl Cellulose Powder E466

CMC Sodium Salt, Sodium Carboxymethyl Cellulose

Food Industry

CMC is widely used as a thickener, stabilizer, and emulsifier. It improves texture, prevents separation in dressings and beverages, stabilizes ice cream, and enhances the mouthfeel of sauces, soups, and puddings. It is also used in gluten-free, vegan, and low-calorie foods to replace gelatin or fat while maintaining texture

CMC is registered as E466 or E469 (when it is enzymatically hydrolyzed). It is used as a viscosity modifier or thickener and to stabilize emulsions in various products, including ice cream, mayonnaise, and beverages. It is also used extensively in gluten-free and reduced-fat food products.CMC injections have also been used in food fraud, to fraudulently increase the weight and visual appeal of shrimp and prawns so as to short-weight customers.

CMC's variable viscosity (high while cold, and low while hot) makes it useful in the preparation of cold foods and textures in beverages and edible gels. With a degree of substitution (DS) around 1.0, it can prevent dehydration and shrinkage of gelatin while also contributing to a more airy structure. In some foods, it can be used to control oil and moisture content.

CMC is used to achieve tartrate or cold stability in wine, which can prevent excess energy usage while chilling wine in warm climates. It is more stable than metatartaric acid and inhibits tartrate crystal nucleation and growth.

CMC powder is widely used in the ice cream industry to make ice creams without the need for churning or extremely low temperatures.CMC is used in baking breads and cakes. The use of CMC gives the loaf an improved quality (e.g., texture) at a reduced cost by reducing the need for fat. CMC is also used as an emulsifier in sweet biscuits. Dispersing fat uniformly in the dough improves the release of the dough from the molds and cutters, achieving well-shaped biscuits without any distorted edges. It can also help to reduce the amount of egg yolk or fat used in making the biscuits. The use of CMC in candy preparation ensures smooth dispersion in flavor oils and improves texture and quality. CMC is used in chewing gums, margarine, and peanut butter as an emulsifier

Pharmaceutical and Healthcare

CMC functions as a binder, disintegrant, and controlled-release agent in tablets, ensuring proper drug release and tablet integrity. It is also a key ingredient in artificial tears and lubricating eye drops, forming a protective, moisturizing film on the cornea

Industrial and Technical Uses

CMC serves as a rheology modifier, dispersant, and film former in personal care, textiles, paper, ceramics, and paints. In mining, it is used for mineral flotation and depressants, while in oilfield applications, it controls fluid loss and enhances drilling fluid performance. CMC is also used in batteries as a binder in anodes and to reinforce separators

Other Uses

CMC is employed in detergents, reusable heat packs, wound healing, leather crafting, and as a stabilizer in diet pills and laxatives. Its variable viscosity—high when cold and low when hot—makes it suitable for cold foods, beverages, and edible gels

Safety and Regulatory Status

CMC is generally considered non-toxic, hypoallergenic, and safe for consumption, with regulatory approval as E466 in food products. Its plant-based origin and water solubility make it a versatile and environmentally friendly additive
