Product Details

Sodium Carboxymethyl Cellulose (CMC)

Sodium carboxymethyl cellulose (CMC), also referred to as cellulose gum, is a carboxymethylated cellulose derivative belonging to the anionic cellulose ether category and is considered one of the most important ionic cellulose gums. It is generally manufactured through the reaction of natural cellulose with caustic alkali and monochloroacetic acid.

CMC has a molecular weight ranging from several thousand to several million. It appears as a white to off-white fibrous powder or granular material with a density of 0.5–0.7 g/cm³. The product is nearly odorless, tasteless, and hygroscopic, and it can be easily dispersed in water to produce a transparent gel-like solution.

Product Application of Sodium Carboxymethyl Cellulose (CMC)

Sodium carboxymethyl cellulose (CMC) can function as a thickener, stabilizer, and emulsifier in various industries.

Food Applications:
Edible CMC offers excellent thickening, emulsifying, shaping, water-retention, and stabilizing properties. Its addition to food products can help lower production costs, improve product quality, enhance flavor, and extend shelf life. As an effective food additive, it is widely used in solid and liquid beverages, canned foods, candies, pastries, meat products, biscuits, instant noodles, quick-cooking foods, frozen desserts, soy milk, yogurt, peanut milk, fruit tea, and fruit juice. The application method and dosage may vary depending on the specific food product.
Pharmaceutical Applications:
Due to its good biocompatibility and biodegradability as a polysaccharide material, sodium carboxymethyl cellulose is also extensively used in pharmaceutical applications.
