Patent number: 6407045Abstract: The invention set out to improve the oxidizing and bleaching effect of inorganic peroxygen compounds in dishwashing, more particularly machine dishwashing, in terms of their storage stability. This was essentially achieved by using particulate compounds corresponding to formula R1R2R3N−CH2CN X+, in which R1, R2, and R3 independently of one another represent an alkyl, alkenyl or aryl group containing 1 to 18 carbon atoms, in addition to which the groups R2 and R3 may even be part of a heterocycle including the N atom and optionally other hetero atoms, and X is a charge-equalizing anion. Dishwashing detergents, more particularly machine dishwashing detergents, contain about 1% by weight to 10% by weight of this bleach-boosting agent.Type: GrantFiled: October 2, 2001Date of Patent: June 18, 2002Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Christian Nitsch, Horst-Dieter Speckmann, Juergen Haerer, Andreas Lietzmann, Susan P.

Patent number: 6221824Abstract: The storage stability of bleach-activating acetonitrile derivatives in solid detergent compositions was to be improved. This was essentially achieved by the use of compounded compounds corresponding to formula R1R2R3NxCH2CN X−, in which R1, R2 and R3 independently of one another represent an alkyl, alkenyl or aryl group containing 1 to 18 carbon atoms, in addition to which the groups R2 and R3 may even be part of a heterocycle including the N atom and optionally other hetero atoms, and X is a charge-equalizing anion. “Compounds” of this type are produced by drying in vacuo, for which purpose a suspension of the acetonitrile derivative and a solid carrier material is introduced into a mixer and the resulting mixture is dried with superheated vapor. Dishwashing detergents, more particularly machine dishwashing detergents, contain about 1% by weight to 10% by weight of this bleach boosting compound.Type: GrantFiled: February 25, 2000Date of Patent: April 24, 2001Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Andreas Lietzmann, Artiga Gonzalez, Stefan Hammelstein, Christian Nitsch, Horst-Dieter Speckmann
