Chitosan is a naturally occurring polysaccharide derived from chitin, a substance found in the exoskeletons of crustaceans such as shrimp and crabs. It is obtained through the deacetylation of chitin, resulting in a positively charged polymer with biocompatible and biodegradable properties.
Function
Chitosan possesses various functional properties, including antimicrobial, wound healing, and drug delivery capabilities. It forms a gel-like substance in acidic conditions, making it suitable for encapsulating drugs and promoting controlled release. Additionally, its positively charged nature enables interactions with negatively charged molecules, such as bacteria and toxins, leading to antimicrobial effects.
Application
1. Pharmaceutical Industry: Chitosan is widely used in pharmaceutical formulations for drug delivery systems, wound dressings, and tissue engineering scaffolds due to its biocompatibility and controlled release properties.
2. Food Industry: Chitosan is utilized as a natural preservative, food additive, and clarifying agent in food and beverage products. It can inhibit microbial growth, improve shelf life, and clarify liquids by binding with impurities.
3. Cosmetics Industry: Chitosan is incorporated into cosmetic formulations for its moisturizing, film-forming, and antimicrobial properties. It is used in skincare products, hair care products, and oral care products to enhance product efficacy and safety.
