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.

Chitosan compositions

Aqueous dispersions of certain amines, with Bronstedt acids having a pKa of at least 6, are stable and are useful as rinse-added fabric softeners.

Textile treatment compositions

Fabric softening compositions which are rapidly biodegradable and particularly shelf stable are disclosed. These compositions contain a specific quaternary ammonium, and are formulated in a narrowly defined pH range.

Biodegradable fabric softeners

Rinse-added fabric softening compositions containing a fabric softening active system at least 10% of which consists of certain di(higher alkyl) cyclic amines, and relatively low concentrations of polymeric soil release agents such as hydroxyether cellulosic polymers, copolymeric blocks of terephthalate and ethylene oxide or propylene oxide and cationic guar gums.
