Abstract
Granular detergent compositions with improved powder characteristics and good detergency are obtained by adjusting the proportion of an .alpha.-olefinsulfonate in anionic surfactants to 15-50% by weight, selecting the molar ratio of a silicate in terms of M.sub.2 O.xSiO.sub.2 wherein M stands for an alkali metal within the range of 2.5-3.6 and limiting the amount of an alkali metal sulfate to 4% or less in detergents containing builders comprising mainly silicates, carbonates and hydroxypolycarboxylates but being free of a polyphosphate.
