Disclosed is a detergent composition comprising a polyhydroxy fatty acid amide surfactant of the formula: <IMAGE> wherein R1 is H, C1-C4 hydrocarbyl, 2-hydroxy ethyl, 2 hyroxy propyl, or a mixture thereof, R2 is C5-C31 hydrocarbyl, and Z is a polyhydroxy-hydrocarbyl having a linear hydrocarbyl chain with at least 3 hydroxyls connected directly to said chain, or an alkoxylated derivative thereof, and a non-borate, non-borate-forming bleaching agent such as the persulfates and especially the percarbonate bleaches. Mixtures of non-perborates with bleach activators such as tetraacetyl ethylene diamine are also used in the compositions. Also disclosed is a method for cleaning substrates, such as fabrics, fibers, textiles, hard surfaces, etc., at temperatures below about 50 DEG C., especially below about 40 DEG C., with a detergent composition containing polyhydroxy fatty acid amide surfactant, auxiliary detersive surfactants, optional detersive adjunct ingredients, and bleaching agent, wherein the bleaching agent is a non-borate, non-borate-forming bleaching agent, especially percarbonate bleach.
