Abstract (en)

[origin: DE19908051A1] The aim of the invention is to improve the stability in storage of bleach-activating acetonitrile derivatives contained in solid cleaning agent compositions. To this end, compounded compounds of formula R<1>R<2>R<3>N<+>CH2CN X<-> are used in which R<1>, R<2> and R<3>, independent of one another, represent an alkyl group, alkenyl group or an aryl group with 1 to 18 C atoms, whereby groups R<2> and R<3> can also be part of a heterocycle which includes the N atom and optionally includes additional heteroatoms, and X represents a charge-compensating anion. Compounds of this type are produced by drying in a vacuum, whereby a suspension of the acetonitrile derivative and of a solid supporting material is placed in a mixer, and this mixture is dried using superheated steam. Agents used, in particular, for the machine cleaning of dishes contain approximately 1 wt. % to 10 wt. % of such a compound that intensifies bleaching.
