Providing chitosan and its derivatives

Chitosan *1, made from crab shells, is biocompatible, and so known for being safe, as well as for its antibacterial and moisturizing properties. As such it is used in a wide range of applications. This natural high polymer product, whose molecular weight is controlled at a high level, is renowned throughout the industry.
We extract the active ingredients from a diversity of marine life and natural products, facilitating commercialization.

  • *1 Naturally-occurring chitin, found in the shells of crustaceans such as crabs and shrimp as well as other arthropods, is a polysaccharide with a chemical structure similar to cellulose. Chitosan is produced from chitin by alkaline hydrolysis.

Features and advantages

  • We have developed a system for integrated production of chitosan starting with the exoskeletons of crabs, which results in a high-quality product. We provide customized products to suit customer needs, and we develop various types of chitin and chitosan derivatives*2 as well.
  • *2 Chemically modified chitosan, which has new functions.
