Detergent Compositions

摘要

An effervescent granule for use in particulate detergent compositions which comprises (a) a particulate acid source; and (b) a particulate carbonate source characterised in that the ratio of the d50 particle size of the acid source to the carbonate source is from less than 2:1 to greater than 1:1 is provided. The granules are surprisingly more effective if the particle sizes of the reacting constituents are similar.
