Carboxymethyl cellulose sodium (CMC) is widely used as a thickening agent, stabilizer, and emulsifier in various industries due to its water solubility and viscosity control properties. In the food industry, it serves as a binder and texture modifier in products like ice cream, sauces, and dressings, preventing ice crystal formation and improving mouthfeel. It is also used in gluten-free baked goods to enhance moisture retention and elasticity. In pharmaceuticals, CMC acts as a disintegrant in tablets, helping them break apart upon ingestion for faster drug release. It is also used in liquid medications to suspend active ingredients and maintain uniformity. In cosmetics, CMC provides viscosity and film-forming ability in lotions, creams, and toothpastes, improving spreadability and stability. Industrial applications include use in detergents to prevent soil redeposition, in textile printing as a thickener for dyes, and in paper manufacturing to improve strength and water retention. Its biocompatibility and non-toxic nature make it suitable for medical applications such as wound dressings and ophthalmic solutions, where it provides lubrication and moisture retention.
