Compositions comprising chitosan in the form of a network of nano-sized fibres. There is also provided a process for making such compositions. The compositions have improved solubility and activity. The compositions are useful in hair care, skin care, odour control, wound care, blood management, sanitary compositions, oral care, film formation, hard surface treatment, fabric treatment, release of hydrophobic or hydrophilic materials, plant care, water purification and drug delivery. L'invention concerne de compositions comprenant du chitosane sous la forme d'un réseau de fibres de dimension nanométrique. L'invention concerne également un procédé destiné à préparer de telles compositions. Ces compositions présentent une solubilité et une activité améliorées, et sont utiles pour soigner les cheveux et la peau, pour contrôler des odeurs, pour traiter des plaies, pour traiter le sang, en tant que compositions sanitaires, pour des soins buccaux, pour la formation de films, pour le traitement de surfaces dures, pour l'apprêt thermique, pour libérer des matériaux hydrophobes ou hydrophiles, pour soigner les plantes, pour purifier l'eau et pour administrer des médicaments.
