Chitosan is a biopolymer derived from chitin, which is found in the exoskeletons of crustaceans like shrimps and crabs. It is widely recognized for its biocompatibility, biodegradability, and non-toxicity, making it suitable for various applications. Applications: 1. Biomedical: Chitosan is used in various biomedical applications, including wound dressings, scaffolds for tissue regeneration, drug delivery systems, and dental materials. 2. Nutraceuticals: Chitosan is sometimes used in dietary supplements for its purported cholesterol-lowering and weight loss properties, although scientific evidence supporting these claims is limited. 3. Agrochemicals: Chitosan-based formulations are used in agriculture as biopesticides, plant growth promoters, and soil amendments due to their biocompatibility and biodegradability. 4. Food and Beverage: Chitosan is employed in the food industry as a natural preservative and clarifying agent, as well as in wine and beer production to remove impurities. 5. Cosmetics: Chitosan is utilized in cosmetic formulations for its moisturizing, film-forming, and texturizing properties, appearing in products such as creams, lotions, and hair care products.
