SODIUM CARBOXYMETHYL CELLULOSE

Sodium carboxymethyl cellulose is a water dispersible sodium salt of carboxy-methyl ether of cellulose that forms a clear colloidal solution.
Sodium carboxymethyl cellulose is a hygroscopic material that has the ability to absorb more than 50% of water at high humidity.
Sodium carboxymethyl cellulose is also a natural polymeric derivative that can be used in detergents, food and textile industries.

Sodium carboxymethyl cellulose can be used to stabilize palladized iron nanoparticles, which can further be utilized in the dichlorination of contaminated subsurfaces.
Sodium carboxymethyl cellulose may also be used as a polymeric matrix to form a composite with a crystalline nanofibril for the development of sustainable bio-based polymers.
Sodium carboxymethyl cellulose can also bind with a hard carbon electrode for the fabrication of sodium ion-batteries.

Sodium carboxymethyl cellulose (E 466) is currently authorised as a feed additive for all animal species, without a minimum and a maximum content.
Sodium carboxymethyl cellulose is also authorised, quantum satis, for use as a food additive.

Sodium carboxymethyl cellulose is identified with the single Chemical Abstracts Service (CAS) number 9000-32-4, and the European Inventory of Existing Chemical Substances (EINECS) number 618-378-6.
Sodium carboxymethyl cellulose is the partial sodium salt of a carboxymethyl ether of cellulose.
The cellulose is obtained directly from natural strains of fibrous plant material.
Sodium carboxymethyl cellulose is prepared by the etherification reaction between the alkali-cellulose complex and monochloroacetic acid with consequent formation of the additive and sodium chloride as a by-product.

Sodium carboxymethyl cellulose is marketed in the form of white or slightly yellowish or greyish odourless and tasteless granules or fibrous powder.
Sodium carboxymethyl cellulose is almost insoluble in ethanol.
Sodium carboxymethyl cellulose yields a viscous colloidal solution with water.

The applicant claims that the feed additive sodium carboxymethyl cellulose is specified to be manufactured to meet the specifications set for its use as a food additive.
The main specifications as food and feed additive are: carboxymethyl groups > 0.2 and < 1.5%, loss on drying < 12%, sodium glycolate < 0.4%, sodium < 12.4% and pH 5–8 (1% colloidal solution).

Sodium carboxymethyl cellulose is specified to have a shelf life of several years.
No specific information on the stability of sodium carboxymethyl cellulose or its capacity to homogeneously distribute in feed was made available.

Sodium carboxymethyl cellulose is intended to be used as a technological additive (functional group: emulsifier, stabilizer, binder, thickener and gelling agents) in feedingstuffs and premixture for all animal species, with no recommendation of a minimum or maximum content.

Sodium carboxymethyl cellulose (Na CMC) is used for its thickening and swelling properties in a wide range of complex formulated products for pharmaceutical, food, home, and personal care applications, as well as in paper, water treatment, and mineral processing industries.

Uses:

Carboxymethyl ether cellulose sodium salt used in drilling muds, in detergents as a soil-suspending agent, in resin emulsion paints, adhesives, printing inks, textile sizes, as protective colloid in general.
Sodium carboxymethyl cellulose is used as stabilizer in foods.
Sodium carboxymethyl cellulose is used in pharmaceuticals as a suspending agent, tablet excipient, viscosity-increasing agent.
Low viscosity is usually used in thin aqueous solutions.
Medium viscosity is used to make solutions that look like a syrup.
