Sodium Carboxymethyl Cellulose (CMC) is broadly used in ophthalmic, injectable, oral, and topical pharmaceutical formulations. It is used primarily as a binder or matrix former for solid dosage forms.
Sodium Carboxymethyl Cellulose has the functions of thickening, suspending, emulsifying, stabilizing, shaping, filming, bulking, anti-corrosion, retaining freshness, acid-resisting, health protecting, etc.
It is widely used in modern food industry, such as frozen foods, solid drinks, fruit juices, jams, lactic acid drinks, condiments, biscuits, instant noodles, bakery products, meat products, etc.
Sodium Carboxymethyl Cellulose has good thickening property, water retention, dispersion stability, filming and chemical stability. It has high viscosity even in low concentration, and makes the food taste delicate and smooth; it can reduce the syneresis of food and extend the shelf life; it can control the crystal size in frozen food and prevent the stratification between oil and water.
Sodium Carboxymethyl Cellulose (CMC) – E466
Sodium Carboxymethyl Cellulose (CMC) is used as thickener, suspending agent and rheology modifier in food application. In food products it can absorb and hold water, can thicken and work as a binder, control crystal growth, increase shelf life, and provide expected texture or body.
Sodium Carboxymethyl Cellulose (CMC) is used in food applications like ice creams, baking breads and cakes, high quality biscuits, chewing gums, margarines, peanut butter, diet pills, toothpaste, laxatives, etc.
Sodium Carboxymethyl Cellulose is also widely applied in other applications such as electronics, pesticides, leathers, paints, plastics, printing, ceramics, chemical industry, detergents, textile sizing, reusable heat packs, various paper products, etc.
Chemical & Detergent:
Sodium Carboxymethyl Cellulose is the basic ingredient of powder detergent, especially non-phosphorus powder. It has the characteristics of colloid. When used in detergent powder, it can stabilize the bubble, protect both hands and effectively prevent washes from being contaminated after washed by synthetic detergent.
In the textile industry, Sodium Carboxymethyl Cellulose can act as the sizing agent for the warp sizing of fabrics including cotton, gloria, chemical fiber and blend. The print paste of rayon fiber usually contains cleaning solvent with high boiling point, dye, water and enough thickening agents.
Sodium Carboxymethyl Cellulose helps to reduce the pores on the surface and enhance oil resistance of paper – Sodium Carboxymethyl Cellulose can improve the brightness and gloss of paper – Sodium Carboxymethyl Cellulose can increase the stiffness and smoothness of paper, and control curly phenomena.
Sodium Carboxymethyl Cellulose used as thickener, binder, film former and suspending agent. Improves brushing performance of paints and restrict crystalline growth of fillers. Sodium Carboxymethyl Cellulose is used in water-soluble paints, plastic emulsion paints and in dry & oil bound distemper.
Sodium Carboxymethyl Cellulose can be used in the production of welding electrodes. In the welding electrode industry, when manufacturing welding electrodes, arc stabilizers, slag forming agents, alloying element powders and water and water glass are needed to mix together and configure it into an electric welding rod, extrude it together with the copper core wire and apply pressure to the surface of the core wire. In order to improve the pressure coating effect, Sodium Carboxymethyl Cellulose is added to the welding flux for lubrication. However, the skeleton structure of Sodium Carboxymethyl Cellulose can be used as a lubricant. In addition, Sodium Carboxymethyl Cellulose can also be used as a gas-generating agent.
The advantages of Sodium Carboxymethyl Cellulose in the production of welding electrodes:
• After adding Sodium Carboxymethyl Cellulose, the welding rod has good pressure coating, good lubricity, and the welding flux is not easy to fall off.
• Sodium Carboxymethyl Cellulose has obvious price advantage and is much cheaper.
• When Sodium Carboxymethyl Cellulose and alkaline earth metal hydroxide are used together, the pressure coating effect is greatly changed, and the quality of the electrode is significantly improved.
