FAQs of Carboxymethyl cellulose (CAS No. 9000-11-7) , E466 , Sodium carboxy methyl cellulose:

Q: How is Carboxymethyl cellulose (E466) typically used in various industries?

A: Carboxymethyl cellulose is commonly incorporated as a thickener, stabilizer, emulsifier, and binder. In foods, it enhances texture and consistency; in pharmaceuticals, it acts as a binder or active stabilizer. It also finds roles in detergents, cosmetics, ceramics, textiles, and oil drilling for its functional properties.

Q: What quality standards does this CMC product meet?

A: This sodium carboxymethyl cellulose conforms to FCC, EU, and GB quality standards. It is strictly limited for heavy metals (<20 ppm as Pb, <2 ppm lead, <2 ppm arsenic), microbial presence, and meets specifications for ash content, pH stability, and purity.

Q: When should Carboxymethyl cellulose be chosen over other thickeners?

A: CMC is ideal when a non-toxic, odorless, tasteless, water-soluble, and stable thickener is needed, especially for sensitive applications like food and pharmaceuticals. Its versatility and high purity make it suitable for products requiring tight regulatory compliance and superior texture improvement.

Q: Where is the main source of Carboxymethyl cellulose, and how is it manufactured?

A: The primary source of CMC is plant-derived cellulose. It is chemically modified through carboxymethylation, during which cellulose reacts with sodium monochloroacetate and alkali to form the sodium carboxymethyl ether, producing the fine powder that is marketed.

Q: What is the typical process for using CMC in a formulation?

A: To use CMC, disperse the powder gradually into water under continuous stirring to form a homogeneous solution. Its high solubility ensures easy integration into formulations, whether in food products, liquid detergents, or coatings.

Q: How does CMC benefit the products functionality?

A: CMC improves viscosity, prevents phase separation, and enhances texture in liquid and semi-solid products. Its stability in a wide pH range and compatibility with various ingredients make it an efficient additive for extending shelf life and optimizing product quality.
