FRANCE CHITINE Natural product Chitin and chitosan Production Uses of chitosan Production capacity Codification of products

The chemical structure of chitin, a natural polymer, is very close to that of mucopolysaccharides (heparin and hyaluronic acid), whose biological tolerance has been demonstrated for a long time. In addition, it is an efficient trapper of heavy metals that are responsible for very many contact allergies; therefore it is really interesting for skin allergies.

Chitin is a particularly effective hydrating agent. It has two advantages: it supplies water and it avoids dehydration. In addition, the great advantage of chitin and its derivatives is the lasting quality of their hydrating effect.

Lastly, chitosan forms a protective tensor film on the skin's surface that can fix other active principles for the skin. Thus other hydrating agents, solar filters, organic acids or other active principles can be combined with the derivatives of chitin. Chitin facilitates their effects.

Chitin and its derivatives allow active principles to be placed in close contact with the skin by means of a medium that is not only a film-forming tensor but is especially hydrating. This is a new double advantage that makes chitosan of great interest in cosmetics.

Therefore chitin and chitosan are now used in skin creams, shampoos, lacquers, varnishes, etc. Many patents have been registered and the potential range of new applications is endless.
