Una composición granular adecuada para su incorporación en una composición detergente en partículas, comprendiendo la composición granular (a) un ingrediente coloreado o fluorescente, (b) un material vehículo para el ingrediente coloreado o fluorescente, que se caracteriza porque el material vehículo (b) es ácido cítrico, y la composición granular comprende además (c) un material de barrera soluble en agua o dispersable en agua, y (d) un modificador del flujo inorgánico. A granular composition suitable for incorporation into a particulate detergent composition comprises: (a) a coloured or fluorescent ingredient, for example, a photobleach such as zinc or aluminium phthalocyanine sulphonate; (b) a carrier material for the coloured or fluorescent ingredient which is an alpha -hydroxy organic acid, preferably citric acid; (c) a water-soluble or water-dispersible barrier material, preferably a water-soluble starch or polyvinyl alcohol; and (d) an inorganic flow modifier, for example, silica and/or china clay. Preferably, the coloured or fluorescent ingredient is dispersed onto the alpha -hydroxyacid which is mixed with part or all of the inorganic flow modifier and the whole treated with the barrier material, then granulated with any remaining inorganic flow modifier. The granular material can be incorporated into particulate detergent compositions, where it shows a reduced tendency to leave stains on washed fabrics.
