Patent number: 6165961Abstract: A water-free surfactant composition containing: (a) a fatty alcohol sulfate corresponding to the formula R.sup.1 O--SO.sub.3 X, where R.sup.1 is a linear alkyl chain, and X is an alkali metal, alkaline earth metal, ammonium, alkyl ammonium, alkanolammonium or glucammonium; and (b) an alkyl benzenesulfonate corresponding to the formula R.sup.2 --Ph--SO.sub.3 X where R.sup.2 is an alkyl chain containing 10 to 14 carbon atoms, Ph is a phenyl group and X is alkali metal, alkaline earth metal, ammonium, alkyl ammonium, alkanolammonium or glucammonium. The fatty alcohol sulfate and alkyl benzenesulfonate are present in the surfactant composition in a weight ratio of 50:50 to 90:10. The water-free surfactant composition provides a reduced potential for irritation, good flow behavior and solubility in cold water. The surfactant composition is useful in laundry detergents, dishwashing detergents and cleaners.Type: GrantFiled: May 20, 1999Date of Patent: December 26, 2000Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Karl-Heinz Schmid, Ditmar Kischkel, Thomas Krohnen, Andreas Syldath
