Sodium carboxymethyl cellulose

Description:
Sodium carboxymethyl cellulose (CMC) is a water-soluble polymer derived from cellulose, characterized by its carboxymethyl groups that enhance its solubility and functionality. It appears as a white to off-white powder or granules and is odorless. CMC is widely used as a thickening agent, stabilizer, and emulsifier in various industries, including food, pharmaceuticals, and cosmetics. Its ability to form viscous solutions makes it valuable in controlling the texture and consistency of products. CMC is non-toxic and biodegradable, making it an environmentally friendly option. The substance exhibits excellent film-forming properties and can improve the stability of emulsions and suspensions. Additionally, it has applications in the textile and paper industries, where it serves as a sizing agent. The viscosity of CMC solutions can be influenced by factors such as concentration, molecular weight, and the degree of substitution of carboxymethyl groups. Overall, sodium carboxymethyl cellulose is a versatile compound with a wide range of applications due to its unique rheological properties.
