USE OF NEW BLEACH ACTIVATORS IN DISHWASHING DETERGENTS

摘要

Use of a composition as a bleach activator in a dishwater detergent composition, said composition being obtainable by reacting, at high temperatures in the presence of water, (i) a compound of formula (I) wherein; R<1>, R<2>, R<3> 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 R<1> and R<2>, 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 (preferably unsubstituted) with one or more C1-C5-alkyl, C1-C5-alkoxy, C1-C5-alkanoyl, phenyl, amino, ammonium, cyano, cyanamino, chlorine, bromine, a N-R<6> group or a R<3>-N-R<6> group, in which R<6> is hydrogen, C1-C5-alkenyl, C2-C5-alkynyl, phenyl, C7-C9-aralkyl, C5-C7-cycloalkyl, C1-C6-alkanoyl, cyanomethyl or cyanide; R<4> and R<5> are the same or different and are hydrogen, C<1>-C4-alkyl, C1-C4-alkenyl, C1-C4-alkoxy-C1-C4-alkyl, phenyl or C1-C3-alkylphenyl; and X<-> is an anion; with (ii) 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.
