Process for obtaining a combination with a synergic effect by the reaction of epoxyalkanes located at the end or in the interior of the chain with 1 mole of diethanolamine per mole of epoxyalkane and addition of 3 to 20 moles of ethylene oxide to the aliphatic hydroxyamines obtained, adjacent, internal or located at the end of the chain with straight alkyl chains (10 to 20 carbon atoms) and 1 to 4 carbon atoms in the alkylamine residue, as well as dissolving the reaction product in aqueous solutions of straight-chain alkylbenzenesulphonates or alkanesulphonates (8 to 20 carbon atoms) in the quantitative ratio of 1:1 to 1:15, so that the content of both groups of substances is 2 to 30% by weight.
