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.

Cleaning compositions containing bleach and stability-enhanced enzymes

Automatic dishwashing detergent compositions comprising a certain combination of metasilicate with other silicate (polymeric) components are disclosed. Particularly preferred compositions also comprise low foaming surfactant and detergency builders.

Granular detergent compositions comprise conventional ingredients and a perfume delivery system which comprises Type X or Type Y Zeolites having a perfume releasably adsorbed within their pores, and a barrier matrix comprising a fluid polyol or diol which is insoluble with the perfume and a solid polyol containing more than three hydroxyl moieties. Methods of depositing said perfume onto fabric surfaces are disclosed.

Laundry and cleaning compositions which comprise large pore size redox catalysts.

Detergent compositions comprising large pore size redox catalysts

Disclosed are rinse additive compositions containing an insoluble inorganic zinc salt useful for inhibition of glassware corrosion caused by automatic dishwashing detergents in the dishwasher. These compositions are particularly desirable because use of them in the dishwasher does not result in precipitation of zinc insolubles on the dishware or dishwasher parts.
