Cellulose Gum (Sodium carboxymethyl cellulose or CMC)

Sodium carboxymethyl cellulose (CMC) is a type of cellulose gum that is commonly used as a food additive, thickening agent, stabilizer, and emulsifier. It is derived from cellulose, which is a natural polymer found in plant cell walls. CMC is produced by treating cellulose with sodium hydroxide and monochloroacetic acid, which replaces some of the hydroxyl groups on the cellulose molecule with carboxymethyl groups.

In food applications, CMC is commonly used as a thickener and stabilizer in products such as ice cream, salad dressings, and baked goods. It is also used in some non-food applications, such as in toothpaste, as a binder in tablets, and as a paper coating.

CMC is generally recognized as safe (GRAS) by the US Food and Drug Administration (FDA), and is approved for use in food and other products in many countries around the world. However, some people may have an allergic reaction to CMC, and it is important to check ingredient labels and consult with a doctor if there is any concern.

Overall, CMC is a widely used and safe food additive that helps to improve the texture, consistency, and stability of many common food products.
