Abstract: Compositions containing one or more alkyl lactate sulfate (A) of the general formula (I), R1(OCOCH(CH3))nOSO3M1??(I) in which the radical R1 is a linear or branched alkyl or alkenyl radical having 6 to 30 carbon atoms, the index n is a number in the range from 1 to 5, and the radical M1 is selected from H, Li, Na, K, Ca/2, Mg/2, ammonium, and alkanolamine, one or more compound (B) selected from phosphoric acid and the mono-, di- and tri-salts thereof, wherein the cation of these salts is selected from Li, Na, K, Ca, Mg, ammonium, and alkanolamine, one or more compound (C) selected from citric acid and the mono-, di- and tri-salts thereof, wherein the cation of these salts is selected from Li, Na, K, Ca, Mg, ammonium, and alkanolamine, and water where the following provisos apply: the weight ratio of the sum total of the compounds (B) and (C) to the sum total of the compound (A) is in the range from 1:5 to 1:10.
