Product Description
Chitosan is an off-white powder that is flavorless, semi-transparent, and amorphous. It is soluble in acidic conditions but remains insoluble in alkaline solutions, water, and most ordinary organic solvents. Chitosan decomposes at a temperature of 185°C.
Commercially, it is produced through the deacetylation of chitin, a process that involves treating crab and shrimp shells with sodium hydroxide. Chitosan is known for its unique properties as a fat-absorbing dietary fiber.

Applications
- Water Treatment: Chitosan is widely used in wastewater treatment to remove heavy metals, oils, and other contaminants. Its ability to bind with various pollutants makes it an effective flocculant, helping to clarify water and remove impurities.
- Agriculture: In agriculture, chitosan is used as a bio-pesticide and plant growth enhancer. It helps improve plant resistance to diseases, fungi, and pests while promoting growth by enhancing soil microorganisms.
- Textile Industry: Chitosan is used to treat fabrics, providing them with antimicrobial and odor-resistance properties. It is especially useful in creating hypoallergenic, antibacterial textiles, ideal for medical or sports applications.
- Paper and Pulp Industry: In paper production, chitosan is used as a strengthening agent and as an eco-friendly alternative to synthetic polymers. It improves the paper’s mechanical strength and increases resistance to water, oils, and grease.
- Cosmetics: Chitosan is used as a thickener, film-forming agent, and stabilizer in skincare and haircare products. Its biocompatibility and moisturizing properties make it suitable for formulations that target sensitive skin.
