Carboxymethyl chitosan (CMC) is a derivative of chitosan, created by introducing carboxymethyl groups into the chitosan structure. It has various uses in different industries, including:
- Biomedical Applications: It is used as a drug delivery system due to its biocompatibility and ability to form gels. CMC can also be used in wound healing and as a scaffold for tissue engineering.
- Weight Loss: It is sometimes used in weight loss supplements as it can help in reducing fat absorption and promoting satiety.
- Cosmetics: Due to its moisturizing properties, CMC is included in skin care products, hair care formulations, and as an emulsifier.
- Food Industry: It acts as a food preservative, stabilizer, and thickening agent, often used in food processing, such as in sauces and dressings.
- Agriculture: CMC is used as a biodegradable coating for controlled-release fertilizers and pesticides.
- Water Treatment: Its ability to flocculate (clump together) makes it useful in water purification processes.
Due to its versatility, carboxymethyl chitosan has applications in many fields where biocompatibility, safety, and functionality are essential.
