CMC Sodium Carboxymethyl Cellulose Powder Instant Fast Quick Dissolve Manufacturer
Product Description
Sodium Carboxymethyl Cellulose (also referred as CMC and Carboxy Methyl Cellulose) can briefly be described as an anionic water-soluble polymer produced from naturally occurring cellulose by etherification, substituting the hydroxyl groups with carboxymethyl groups on the cellulose chain.
Being readily dissolved in hot or cold water, Sodium Carboxymethyl Cellulose CMC can be produced in different chemical and physical properties..

Funtion
The main effects of sodium carboxymethyl cellulose powder include thickening, suspension, dispersion, moisture and surface activity.
Sodium carboxymethyl cellulose is a cellulose derivative with good water solubility, thickening and stability, so it has been widely used in many fields. Here are its main functions:
1. Thickener : Sodium carboxymethyl cellulose in solution can effectively increase viscosity, improve the taste and appearance of food or medicine, improve its stability. It can be added to various products to regulate fluidity and consistency 1.
2. Suspension agent : sodium carboxymethyl cellulose has good water solubility, can quickly dissolve in water and form a stable film with the surface of particles, prevent aggregation between particles, improve the stability and uniformity of products .
3 dispersant : sodium carboxymethyl cellulose can be adsorbed on the surface of solid particles, reduce the mutual attraction between particles, inhibit particle agglomeration, and ensure the uniform distribution of materials in the storage process .
4. Moisturizing agent : sodium carboxymethyl cellulose can absorb and lock water, prolong the moisturizing time, and its strong hydrophilicity, can make the surrounding water close to it, play a moisturizing effect .
5 surfactant : sodium carboxymethyl cellulose molecule with polar groups and non-polar groups at both ends, forming a stable interface layer, to play the role of surfactant, widely used in personal care products, cleaning agents and other fields .
Application
Sodium carboxymethyl cellulose (CMC) is a widely used chemical, its application in various fields mainly includes the following aspects :
1. Food industry : In the food industry, CMC is mainly used as thickener, stabilizer, emulsifier and suspension agent. It can improve the taste and texture of food, increase the consistency and smoothness of food. For example, adding CMC to ice cream, jelly, pudding and other foods can make the texture more uniform; It is used as emulsifier in salad dressing, dressing and other foods to make the mixing of oil and water more stable; Used as a suspension agent in beverages and juices to prevent pulp precipitation and maintain an even texture .
2. Pharmaceutical field : In the pharmaceutical field, CMC is used as an excipient, binder, disintegrator and carrier of drugs. Its excellent water solubility and stability make it a key material in the pharmaceutical process. For example, as an adhesive in pill manufacturing to help the pill hold its shape and ensure an even release of the drug; Used as a suspension agent in drug suspension to ensure uniform distribution of drug ingredients and prevent precipitation; Used as a thickener and stabilizer in ointments and gels to improve viscosity and stability .
Dailies chemical : CMC is used as thickener, suspension agent and stabilizer in dailies chemical industry. For example, in personal care products such as shampoo, body wash, toothpaste, CMC can improve the texture and appearance of the product, while having good moisturizing and lubricating properties to protect the skin; Used as an anti-redeposition agent in detergents to prevent dirt from being redeposited .
3. Petrochemical : In the petrochemical industry, CMC is used as a component of oil production fracturing fluids with thickening, filtration reduction and anti-collapse properties. It can improve the viscosity of the mud, reduce the fluid loss of the mud, improve the rheological property of the mud, make the mud more stable in the drilling process, reduce the problem of wall collapse and bit stuck .
4. Textile and paper industry : In the textile and paper industry, CMC is used as a slurry additive and coating agent to improve the strength, smoothness and printability of fabrics and paper. It can improve the water resistance and printing effect of the paper, while increasing the softness and gloss of the fabric during the textile process .
