| Zusammenfassung: | A fire fighting foaming composition or a fire fighting foam comprises chitosan or a salt of chitosan, together with a surfactant. The surfactant may be a protein derived surfactant. Alternatively the surfactant may be either non-ionic or amphoteric and have a hydrocarbon hydrophobic region. The surfactant should not be an anionic surfactant with a hydrocarbon hydrophobic region. |
