Abstract (en)

[origin: EP1741774A1] An automatic machine dishwashing composition comprising at least 1%, preferably at least 2% by weight of nonionic surfactant, a peroxygen bleach compound and a dinuclear manganese-complex having the general formula: wherein Mn is manganese which can individually be in the III or IV oxidation state; each x represents a coordinating or bridging species selected from the group consisting of H 2 O, O 2 2- , O 2- , OH - , HO 2 - , SH - , S 2- , >SO, Cl - , N 3- , SCN - , RCOO - , NH 2 - and NR 3 , with R being H, alkyl or aryl, (optionally substituted); L is a ligand which is an organic molecule containing a number of nitrogen atoms which coordinates via all or some of its nitrogen atoms to the manganese centres; z denotes the charge of the complex and is an integer which can be positive or negative; Y is a monovalent or multivalent counter-ion, leading to charge neutrality, which is dependent upon the charge z of the complex; and q = z/ [charge Y]: wherein at least 50% by weight of the nonionic surfactant is selected from: (a) at least one nonionic surfactant having a melting point greater than 35°C, preferably greater than 40°C; (b) at least one nonionic surfactant in the form of a granule having pores with a number average pore size less than 5µm, the pores containing the nonionic surfactant; and mixtures thereof.
