Abstract

The concentrates consist essentially of 35 to 55% by weight water, 10 to 30% by weight of an alkyl glycoside corresponding to the formula R.sup.1 --O(G).sub.n, in which R.sup.1 is a C.sub.8-22 alkyl radical, G is a glycose unit and n is a number of 1 to 10, 10 to 30% by weight of an alkyl sulfate corresponding to the formula R.sup.2 --O--SO.sub.3 X, in which R.sup.2 is a C.sub.8-22 alkyl radical and X is an alkali or ammonium ion, and 1 to 15% by weight of an alkane sulfonate corresponding to the formula ##STR1## in which R.sup.3 and R.sup.4 independently of one another represent C.sub.1-18 alkyl radicals, with the proviso that the total number of carbon atoms in the alkane sulfonate is between 10 and 20, and Y is an alkali or ammonium ion. They are used as storable, free-flowing and pumpable compounds, preferably for the production of detergents.
