  • Patent number: 6407045
    Abstract: 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: Grant
    Filed: October 2, 2001
    Date of Patent: June 18, 2002
    Assignee: Henkel Kommanditgesellschaft auf Aktien
    Inventors: Christian Nitsch, Horst-Dieter Speckmann, Juergen Haerer, Andreas Lietzmann, Susan P. Huestis

  • Patent number: 5888419
    Abstract: Granules are provided that are useful for oxidizing applications when the granules are dissolved in the presence of an active oxygen source. These granules include a salt having the structure of Formula I ##STR1## wherein A is a saturated ring formed by a plurality of atoms in addition to the N.sub.1 atom, the saturated ring atoms including at least one carbon atom and at least one of O, S, and N atoms, the substituent R.sub.1 bound to the N.sub.1 atom of the Formula I structure including either (a) a C.sub.1-24 alkyl or alkoxylated alkyl where the alkoxy is C.sub.2-4, (b) a C.sub.4-24 cycloalkyl, (c) a C.sub.7-24 alkaryl, (d) a repeating or nonrepeating alkoxy or alkoxylated alcohol, where the alkoxy unit is C.sub.2-4, or (e) --CR.sub.2 R.sub.3 C.tbd.N where R.sub.2 and R.sub.3 are each H, a C.sub.1-24 alkyl, cycloalkyl, or alkaryl, or a repeating or nonrepeating alkoxyl or alkoxylated alcohol where the alkoxy unit is C.sub.2-4, the R.sub.2 and R.sub.3 substituents being each H, a C.sub.
