A granular detergent composition is described containing an .alpha.-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 .alpha.-sulfo fatty acid ester salt contained therein. This granular detergent composition comprises (a) at least one .alpha.-sulfo fatty acid ester salt having the general formula [I]: ##STR1## wherein R is an alkyl group having 4 through 20 carbon atoms, R.sub.1 is an alkyl group having 1 through 6 carbon atoms, and M.sub.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.sub.2 is an alkyl group having 8 through 20 carbon atoms, and M.sub.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.

Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
