USE OF A DI-NUCLEAR MN(III) OR MN(IV) COMPLEX IN DISHWASHING COMPOSITIONS CONTAINING A PEROXYGEN COMPOUND FOR REMOVING STARCH-CONTAINING SOIL

摘要

A machine dishwashing composition containing a peroxygen compund as the bleaching agent and having improved bleaching action combined with excellent starch removing properties is disclosed. The compositioncontains a dinuclear manganese complex having the general formula. CHEM as defined in the description, as bleach catalyst and starch removing additive, in an amount corresponding to a Mn-content of from 0.0001 to about 1.0% by weight. A preferred Mn-complex is: [(Mn-TACN)MnIV) mu -O)3MnIV)Me-TACN)]2+(PF6-)2 -
