Abstract
Abstract A granular detergent composition is described containing an α-sulfo fatty acid ester salt and having good granular or powder properties, without containing any phosphate, and also having a less decomposable property of an α-sulfo fatty acid ester salt contained therein. This granular detergent composition comprises (a) at least one α-sulfo fatty acid ester salt having the general formula [I]: ##STR1## wherein R is an alkyl group having 4 through 20 carbon atoms, R 1 is an alkyl group having 1 through 6 carbon atoms, and M 1 is a salt-forming pair ion; (b) at least one fatty acid soap having the general formula [II]: R.sub.2 COOM.sub.2 [II] wherein R 2 is an alkyl group having 8 through 20 carbon atoms, and M 2 is an alkali metal; and (c) at least one polycarboxylic acid salt, the total content of the components (a) and (b) in the composition being 20% through 80% by weight, the weight ratio of the component (a) to the component (b) being within the range of from 4/1 through 1/4, and the content of the component (c) in the composition being 1% through 20% by weight.
