Chitosan is safe and gentle for both humans and the environment. It has a long track record as a cosmetic ingredient and functional food. It is well-known for its excellent biocompatibility and high safety.
Chitosan is a unique polysaccharide that contains numerous reactive amino groups within its molecular structure. These amino groups form various acids and salts, and when dissolved in water, they exhibit cationic properties. Leveraging this cationic nature, chitosan has been used for many years as a cationic coagulant for clarification, sedimentation, filtration enhancement, and general wastewater treatment in the food industry. We provide a consistent production process from crab shells to chitosan, supplying high-quality production on an unprecedented lot scale. Additionally, we can supply products designed to meet specific quality requirements.
