ABSTRACT:
Cleaning compositions, particularly automatic dishwashing detergent compositions, comprising a stability-enhanced amylase and bleach-improving materials are provided. More specifically, the invention relates to granular automatic dishwashing detergents which provide enhanced cleaning/bleaching benefits. The automatic dishwashing compositions comprise stability-enhanced amylase enzymes and one or more bleach-improving compounds, such as organic peroxides, quaternary substituted bleach activators, quaternary substituted peracids and manganese or iron bleach catalysts.
