[origin: GB2344597A] An effervescence composition comprises an acid source and a carbon dioxide source, wherein at least 75% of said acid source has a particle size from 0.1 to 150 microns, preferably from 0.5 to 100 microns. The carbon dioxide source is preferably also of a small particle size. The effervescence composition is in particular useful in solid detergent compositions. The effervescence component is preferably in the form of a granule comprising at least part of the acid source and at least part of the carbon dioxide source. The acid source is preferably citric acid and the carbon dioxide source is a carbonate.
