Abstract: A colored speckle composition for use in particulate laundry detergent compositions comprising a porous granular carrier and at least 0.01 wt % photobleach, preferably at least 0.05 wt %, more preferably at least 0.1 wt %, based on the active ingredient, the composition having an average bulk density of at most 600 g/l, preferably at most 500 g/l, most preferably at most 400 g/l. The carrier system reduces the staining tendency of the photobleach. The most preferred carrier is spray dried detergent base powder. The most preferred photobleach is a blend of Zn and Al sulphonated phthalocyanine.

Abstract: A particulate laundry detergent composition having an equilibrium relative humidity value at 25° C. and 1 atmosphere of at least 10% and comprising an effervescent granule, the effervescent granule comprising an acid source, a carbonate source and a desiccant is provided. The granules are stable even though they are contained within a humid environment.

Abstract: A particulate laundry detergent composition comprising effervescent granules, at a level of from 0.1 to less than 2 wt %, the effervescent granules comprising (a) from 20 to 80 wt % of an acid source and (b) from 20 to 80 wt % of a carbonate source is provided. Surprisingly the effervescent granules provide dispensing benefits at very low concentration levels.

Abstract: 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.

Abstract: An effervescent granule for use in particulate detergent compositions characterised in that it comprises an acid source, a carbonate source and solid surfactant particles is provided.

Abstract: A speckle composition for use in particulate laundry detergent compositions comprising a porous granular carrier, and at least 0.01 wt % photobleach, preferably at least 0.05 wt %, more preferably at least 0.1 wt %, based on the active ingredient the composition being layered with a finely divided high carrying capacity particulate material and/or a water-soluble material. The most preferred photobleach is a blend of Zn and Al sulphonated phthalocyanine.
