Carboxymethylcellulose sodium is widely used as a thickening, stabilizing, and binding agent in the food industry, particularly in products like ice cream, sauces, and baked goods to improve texture and consistency. In pharmaceuticals, it serves as a disintegrant in tablets and a viscosity modifier in liquid medications, ensuring controlled release and ease of administration. It is also a key ingredient in personal care products such as toothpaste, lotions, and shampoos, where it enhances viscosity and stabilizes formulations. Additionally, it is employed in industrial applications like paper coating, textile sizing, and as a drilling fluid additive in oil extraction due to its water retention and thickening properties. In medical settings, it is used in artificial tears and wound dressings for its lubricating and moisture-retaining capabilities.
