What is the Difference Between Sodium CMC and CMC?

CMC (carboxymethyl cellulose) is a compound derived from cellulose, which is an anionic cellulose ether used as a thickener and binder for water-based applications. Sodium CMC, on the other hand, is the sodium salt form of CMC. The key difference between sodium CMC and CMC is their solubility in water:

• Sodium CMC: Easily soluble in both hot and cold water, making it easier to preserve.
• CMC: Poorly soluble in water, making it difficult to preserve as it is.

Both sodium CMC and CMC are used in various industries, such as the food industry, pharmaceutical industry, dentistry, and medicine. Some common applications include toothpaste, laxatives, diet pills, water-based paints, detergents, textile sizing, and paper products. CMC is also used as a viscosity modifier, thickener, and emulsion stabilizer in products like ice cream. However, the use of CMC in food products has raised some concerns regarding its potential impact on gut bacteria and inflammatory bowel disease symptoms. Further research is needed to determine the long-term effects of CMC and other emulsifiers at levels that are commonly consumed.

Comparative Table: Sodium CMC vs CMC

The main difference between sodium CMC and CMC is their solubility in water and their applications. Here is a table summarizing their differences:

Sodium CMC is the sodium salt form of CMC and is easily soluble in hot water, making it easier to preserve and use. CMC, on the other hand, has poor water solubility, which can make it difficult to preserve and use in various applications.
