ABSTRACT:
Stable and homogeneous aqueous formulations of surfactants
Stable and homogeneous aqueous formulations of surfactants having an HLB value of less than or equal to 13, which additionally contain a compound of the formula I ##STR1## in which R.sup.1 is C.sub.1 -C.sub.8 -alkyl, C.sub.1 -C.sub.8 -alkenyl, phenyl, alkylphenyl or phenalkyl having in each case 1 to 4 carbon atoms in the alkyl chain or cyclohexyl, R.sup.2 is hydrogen or one of the radicals mentioned for R.sup.1, or R.sup.1 and R.sup.2, together with the nitrogen atom, are a heterocyclic radical, M is an alkali metal cation, an ammonium cation or one equivalent of an alkaline earth metal or aluminium cation and m and n in each case independently of one another are numbers from 6 to 8.
By the presence of the compounds of the formula I, it is possible to prepare stable and homogeneous aqueous formulations even from those surfactants which are otherwise only sparingly soluble or not soluble at all in water.
