What it is

Carboxymethylcellulose (CMC) is a modified form of cellulose, a natural fiber found in plants. It is made by treating cellulose with chemicals to give it water-soluble properties. CMC is often used as a food additive to improve texture and consistency.

Why it's used

CMC acts as a thickener, stabilizer, and emulsifier in food products. It helps prevent ingredients from separating and gives foods a smoother mouthfeel. It is commonly found in baked goods, ice cream, sauces, dressings, and powdered drink mixes.

Health notes

In the United States, carboxymethylcellulose is generally recognized as safe (GRAS) by the FDA. It is indigestible and passes through the body largely unabsorbed. International bodies like JECFA and EFSA have evaluated CMC and found it safe for consumption. Studies have not shown adverse health effects from typical dietary intake.

Allergen info

Carboxymethylcellulose is not derived from any of the 9 major allergens recognized by the FDA. It is also gluten-free.
