Detergent compositions containing enzymes and calcium ions are found to be more stable when alkyl benzene sulfonate or primary alkyl sulfates surfactants conventionally used therein are replaced by secondary (2,3) alkyl sulfate surfactants. Thus, laundry detergent compositions comprising a secondary (2,3) alkyl sulfate, a source of calcium ions, and one or more protease, cellulase, amylase, lipase or peroxidase detergent enzymes are provided. Bars and granular detergents are also disclosed.
