Detergents

A detergent mixture suitable for use in aqueous liquid detergent compositions consisting essentially of (a) a water-soluble, anionically active olefin sulfonate product having 12 to 21 carbon atoms in the olefin molecular structure, (b) a water-soluble higher alkyl poly (ethenoxy) ether sulfate having 10 to 20 carbon atoms in the higher alkyl group and 1 to 5 ethenoxy groups per molecule, said olefin sulfonate product and said ether sulfate being in the form of a salt selected from the group consisting of sodium, potassium, ammonium and ethanolammonium and (c) a higher fatty acid alkanolamide selected from the group consisting of fatty acid isopropanolamides and fatty acid monoethanolamides in which the higher fatty acyl radical has 10 to 14 carbon atoms, the weight ratio of said sulfate to said sulfonate being in the range of 90:10 to 30:70, said alkanolamide being present in an amount of about 1/2 to 10% by weight and being effective to improve the foam stability as compared with a composition which does not contain said alkanolamide.
