Product Usage

Carboxymethyl Cellulose (CMC) is an important water-soluble cellulose derivative widely used in food, pharmaceutical, personal care, papermaking, and industrial applications. In the food industry, it acts as a thickener, stabilizer, and emulsifier to improve texture and product stability. In pharmaceuticals, it is used as an excipient and in controlled-release formulations to enhance tablet formation and drug release performance. In personal care products, such as toothpaste and detergents, it increases viscosity and system stability. It is also applied in papermaking and textiles as a sizing and finishing agent, offering good film-forming ability and compatibility.
