Fire-fighting concentrate compositions contain fluorinated amine oxide surfactants as well as fluorine free surfactants. Fire-fighting premixes are also provided, as well as a method of fighting fires using the compositions and premixes. These compositions form foams that are effective fire-fighting agents, and in addition the fluorinated amine oxide surfactants adsorb well to dirt, sludge, and other substrates. This adsorption property allows the surfactant to be readily removed from the environment.
Cette invention porte sur des compositions concentrées de lutte contre l'incendie qui contiennent des tensioactifs d' aminoxyde fluoré ainsi que des tensioactifs dépourvus de fluor. On décrit également des prémélanges de lutte contre le feu ainsi qu'un procédé de lutte contre les incendies dans lequel on utilise les compositions et les prémélanges. Ces compositions forment des mousses qui sont des agents efficaces de lutte contre le feu, et de plus les tensioactifs d'aminoxyde fluoré adsorbent bien la saleté, la boue et d'autres substrats. Cette propriété d'adsorption permet d'éliminer rapidement de l'environnement le tensioactif.
