Abstract (en)

[origin: WO0036061A2] The aim of the invention is to improve the oxidising and bleaching effect of inorganic peroxygen compounds in the machine-dishwashing in particular, in such a manner that they remain stable in storage. This was achieved essentially using compounds of the following formula, formulated in particulate form: R<1>R<2>R<3>N<+>CH2CN X<->; wherein R<1>, R<2> and R<3>, independently of each other, are an alkyl-, alkenyl or aryl group with 1 to 18 C-atoms, whereby the groups R<2> and R<3> can also be part of the heterocycle comprising the N-atom and optionally, other heteroatoms; and X is a charge-equalising anion. The inventive agents for washing dishes especially by machine contain approximately 1 wt. % to 10 wt. % of a bleach-reinforcing active agent of this type.
