Abstract: Use of a composition (T) containing one or more silicon organic compounds (I); and optionally one or more surfactant active compounds having one or more perfluorinated units, for the production of fire-extinguishing foam, is claimed, where the percental mass ratio (Q) from the mass of the surfactant active compounds with at least a perfluorinated group and the sum of the mass of the surfactant active compounds and the mass of (I) is less than 5%. Use of a composition (T) containing one or more silicon organic compounds of formula (R 2>-Si(R 1>) 2-O-(Si(R 1>)(R 2>)-O) a1-(Si(R 1>)((O-Si(R 1>)(R 2>)) a2-O-Si(R 1>) 2(R 2>)) b-(Si(R 1>)(R 2>)-O) a3-Si(R 1>) 2R 2>)) (I); and optionally one or more surfactant active compounds having one or more perfluorinated units, for the production of fire-extinguishing foam, is claimed, where the percental mass ratio (Q) from the mass of the surfactant active compounds with at least a perfluorinated group and the sum of the mass of the surfactant active compounds and the mass of (I) is less than 5%.
