Abstract
Use of fatty amines of general formula: ##STR1## wherein R.sub.1 may be a hydrogen atom, or a straight or branched alkyl radical, saturated and containing 4 to 18 atoms of carbon and wherein R.sub.2 is a straight or branched alkyl radical, saturated and containing 4 to 18 atoms of carbon, together with surface agents, to obtain foaming mixtures leading to improved foams. 2 to 50% amines are added, with respect to the weight of the surface agents. Application in the field of fire extinguishing foams, drilling, and in the production of lightweight products.
