Carbosilane containing fire-extinguishing foam

A method of manufacturing a fire extinguishing foam comprising the steps of:

• providing a concentrate comprising a surfactant containing at least one substituted or unsubstituted carbohydrate or carbohydrate derivative and at least one oligosilane,
• wherein the surfactant comprises a molecule that is selected from the group consisting of:
• or mixtures thereof,
• wherein A is a substituted or unsubstituted carbohydrate or carbohydrate derivative comprising one to twenty sugar units, B represents a linker substructure of at least one atom or chain, C is an oligosilane or oxacarbosilane, and D is an oligosiloxane;
• diluting the concentrate with water;
• mixing the diluted concentrate to form a diluted mixture;
• and
• aerating the diluted mixture to form a fire extinguishing foam.
