Carboxymethyl cellulose (CMC) is a versatile cellulose derivative widely utilized in various industries for its exceptional thickening, stabilizing, and emulsifying properties. Derived from cellulose, a natural polymer found in plant cell walls, CMC is modified through a chemical reaction to introduce carboxymethyl groups. This modification enhances its water-solubility and makes it an effective additive in food products, pharmaceuticals, cosmetics, and industrial applications. In the food industry, CMC acts as a thickening agent in a variety of products such as sauces, dressings, and ice cream, contributing to improved texture and stability. Its role as a stabilizer and emulsifier extends to the pharmaceutical and cosmetic industries, where it is incorporated into formulations such as creams and lotions. CMC's ability to modify viscosity, improve suspension, and enhance texture makes it a valuable and versatile ingredient in a wide array of consumer and industrial products.
