Carboxymethyl Cellulose

Carboxymethyl cellulose (CMC) is a type of modified cellulose, a natural polymer found in plant cell walls. It is made by treating cellulose with chemicals to add carboxymethyl groups, making it soluble in water.

CMC is used as a thickener and stabilizer in many foods. It helps prevent ingredients from separating and gives products a smoother texture. It is commonly found in ice cream, baked goods, sauces, and dressings.

In the US, CMC is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is poorly absorbed by the body and is considered to have low toxicity. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated CMC and found it safe for consumption within typical dietary levels. Some studies have explored its potential effects on gut health, but more research is needed.
