  • Publication number: 20240150685
    Abstract: The present invention relates to a product for machine dishwashing, comprising a capsule containing two or more compartments. The first compartment contains a solid, powdered first composition; and a second compartment contains liquid or gel second composition. The bleaching performance has been optimised, leading to better removal of tea stains. This has been achieved by an optimal combination of an alkali metal carbonate, a bleach component, sodium silicate and/or sodium disilicate, a bleach catalyst, and a maximum amount of tetraacetylethylenediamine.
