Abstract

The present invention concerns cellulase-containing granular detergent compositions which are in a "compact" form, i.e. they are of a relatively high density and contain a relatively low amount of inorganic filler salt compared to conventional detergent compositions. In the detergent compositions herein the cellulase is defined by the C14CMC method described herein and preferably comprises a specific single-component endoglucanase.
