Abstract

A water-free surfactant composition is presented having (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 containing 16 or 18 carbon atoms and X is an alkali metal, alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium and (b) an alcohol sulfate corresponding to the formula R.sup.2 O--SO.sub.3 X where R.sup.2 is an alkyl chain containing 12 to 15 carbon atoms consisting of a minimum 20 percent by weight branched alkyl chains and a maximum 80 percent by weight unbranched alkyl chains, and X is an alkali metal or alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium. The surfactant composition has a reduced potential for irritation and good flowability and solubility in cold water. The surfactant composition is useful in laundry detergents, dishwashing detergents and other cleaners.
