A water soluble laundry detergent containing, an organic anionic detergent, nonionic detergent or mixture thereof, a builder salt, preferably including a silicate, a peroxymonosulfate bleaching agent, a bromide promoter for the bleaching agent and one or more of certain optical brighteners which are stable in the presence of the bleach and the promoter. The detergent composition has an excellent detersive action and is of improved bleaching efficiency compared to a non-promoted peroxymonosulfate-containing detergent. With proper selection of brightener acid or salt and judicious control of bromide and peroxymonosulfate contents in a detergent composition containing sufficient alkali to maintain a wash solution pH of at least 9, the ability of sodium bromide to promote removal of undesirable stains from a wash load of laundry is achieved with minimal adverse effect on the brightener and “colorfast”dyed fabrics are not discolored or bleached.
