ABSTRACT The viscosity of an aqueous alpha-olefin sulfonate detergent composition is reduced by treating such composition, usually at a concentration of 30 to 60%, with a viscosity re- ducing proportion, usually from 2 to 20% of a water soluble inorganic halide salt, preferably sodium chloride. By re- ducing the viscosity, detergent compositions containing the alpha-olefin sulfonate detergent are made more readily pourable, pumpable and sprayable, facilitating their use in liquid deter- gents and in spray dried particulate form. Because the addi- tion of halide salt may cause separation into different phases it is possible to increase the concentration of the alpha- olefin sulfonate by utilizing the phase richer in content of such detergent material. The viscosity reducing effect of the halide salt is utilizable in manufacturing the alpha-olefin detergent composition by thinning such composition in the neutralization, bleaching and other steps in its manufacture, thereby allowing the use of less water and facilitating an increase in detergent solids content of the final alpha-olefin sulfonate detergent compositions made.
