Sodium carboxymethyl cellulose (CMC) is a derivative of cellulose, which is a natural polymer found in plants. CMC is a white, odorless powder that is commonly used as a food additive, thickening agent, and emulsifier. In the food industry, CMC is used in a variety of products, including ice cream, yogurt, baked goods, and processed meats. Sodium carboxymethyl cellulose is added to these products to improve their texture, increase their viscosity, and enhance their stability.
