Automatic dishwashing detergent compositions, comprising particular quaternary-substituted bleach activators, are provided. More specifically, the invention relates to granular automatic dishwashing detergents which provide enhanced cleaning/bleaching benefits through the selection of quaternary-substituted bleach activators having specific features, such as caprolactam or valerolactam leaving groups and/or the ability to form particular cationic aliphatic peracid structures in solution. Preferred automatic dishwashing compositions comprise amylase enzymes. Included are preferred activator compounds and methods for washing tableware in domestic automatic dishwashing appliances using the activators.
