Abstract

The aim of the invention is to improve the storage stability and flow and pumping characteristics of liquid alkylglycoside preparations by adding the minimum amounts of non-alkylglycosidic active substances, so that, owing to the increase ease with which they can be handled, the preparations can be used in the manufacture of washing and cleaning agents. This has been achieved by the use of aqueous mixtures consisting essentially of: 20 to 60% by weight of an alkylglycoside of the formula R.sup.1 --O(G).sub.n, in which R.sup.1 is an alkyl group with 8 to 22 C-atoms, G is a glycose unit and n is a number between 1 and 10; 0.1 to 3% by weight of a sulphate-type or sulphonate-type anionic surfactant selected from the group comprising alkyl sulphates, ether sulphates, alkanesulphonates, .alpha.-sulpho fatty acids, their carboxylic acid esters, sulphonation products of alkylbenzenes, alkenes or unsaturated fatty acids and mixtures thereof, the proportion by weight of alkylglycoside to sulphate and/or sulphonate being 200:1 to 20:1; plus 37 to 79.9% by weight water.
