A bleach catalyst composition in the form of non-friable composite granules comprising: i) a manganese complex catalyst being one of three defined formulae herein; ii) a hydrophobic binding agent, preferably selected from silicone oils, C11-C18 fatty acids, C11-C18 fatty acid soaps, C11-C18 fatty esters, tri-, di- and monoglycerides, waxes, solid hydrocarbons and mixtures thereof; and iii) a non-delinquescent or non-hygroscopic soluble core material such as sodium bicarbonate. The granular, manganese complex-based bleach catalyst comosition may be incorporated in detergent and/or bleaching compositions, with good resulting stability and homogeneity of distribution. |
