Use of new bleach activators in dishwashing detergents

A method of cleaning crockery or cutlery using a detergent formulation comprising a bleach activator compound obtained by reacting, at high temperatures in the presence of water,

• a) a compound of the formula
• wherein:
• R1, R2, R3 are the same or different and are linear or branched C1-C24-alkyl groups, C2-C24-alkenyl groups or C1-C4-alkoxy- C1-C4-alkyl groups, substituted or unsubstituted benzyl (preferably unsubstituted), or R1 and R2, in conjunction with the nitrogen atom to which they are bonded, form a ring having 4 to 6 C-atoms, which ring can contain in addition to the nitrogen atom and instead of carbon atoms, one or two oxygen or nitrogen atoms, which ring can be unsubstituted or substituted with one or more C1-C5-alkyl, C1-C5-alkoxy, C1-C5-alkanoyl, phenyl, amino, ammonium, cyano, cyanamino, chlorine, bromine, a N- R6 group or a R3-N-R6 group, in which R6 is hydrogen, C1-C5-alkyl, C2-C5-alkenyl, C2-C5-alkynyl, phenyl, C7-C9-aralkyl, C5-C7-cycloalkyl, C1-C6-alkanoyl, cyanomethyl or cyanide;
• R4 and R5 are the same or different and are hydrogen, C1-C4-alkyl, C1-C4-alkenyl, C1-C4-alkoxy- C1-C4-alkyl, phenyl or C1-C3-alkylphenyl;
• and
• X- is an anion;
• with
• b) an alkali or ammonium salt of an alkyl sulphonate, paraffin sulphonate, aryl
• sulphonate, primary alcohol sulphate or fatty acid alkyl carboxylate or the respective
• acids or their substituted derivatives;
• said method comprising contacting the detergent formulation with moisture or water at a point in time prior to dispensing the detergent formulation into the environment in which the cleaning process takes place.
