description Product Description
Carboxymethyl cellulose is widely used as a thickening and stabilizing agent in food products such as ice cream, yogurt, and sauces to improve texture and consistency. In the pharmaceutical industry, it serves as a binder in tablets and a viscosity modifier in liquid medications. It is also employed in personal care products like toothpaste and lotions for its emulsifying and moisturizing properties. Additionally, it is utilized in paper manufacturing to enhance paper strength and as a water retention agent in cement and plaster. In oil drilling, it functions as a fluid loss control additive in drilling muds.
