Sodium carboxymethyl cellulose (CMC) is a water-soluble polymer derived from cellulose. It is a white, odorless, tasteless powder that is widely used in a variety of industries, including food, pharmaceuticals, cosmetics, and paper. CMC is used as a thickening agent, stabilizer, emulsifier, and suspending agent in a variety of products.
Sodium CMC is produced by reacting cellulose with sodium monochloroacetate. This reaction results in a carboxymethyl substitution of the cellulose molecules, which increases the solubility of the cellulose in water. The degree of substitution (DS) of the CMC molecules is an important factor in determining the properties of the CMC. The higher the DS, the more soluble the CMC is in water.
Sodium CMC is used in a variety of applications due to its unique properties. It is used as a thickening agent in food products such as ice cream, sauces, and dressings. It is also used as a stabilizer and emulsifier in many products, including beverages, dairy products, and baked goods. CMC is also used in pharmaceuticals as a suspending agent and in cosmetics as a thickening agent.
Sodium CMC is a safe and effective additive that is approved by the FDA for use in food and pharmaceuticals. It is non-toxic and non-irritating, and it does not produce any adverse reactions when used in recommended amounts. CMC is also considered to be environmentally friendly, as it is biodegradable and does not produce any hazardous waste.
In conclusion, sodium carboxymethyl cellulose (CMC) is a water-soluble polymer derived from cellulose. It is used as a thickening agent, stabilizer, emulsifier, and suspending agent in a variety of products. Sodium CMC is safe and effective, and it is approved by the FDA for use in food and pharmaceuticals. It is also considered to be environmentally friendly, as it is biodegradable and does not produce any hazardous waste.
