  • Patent number: 6221824
    Abstract: 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.

  • Patent number: 6162781
    Abstract: Foam control granules, for use in particulate laundry detergent compositions, comprise a mobile hydrophobic foam control agent, preferably silicone oil in admixture with hydrophobic silica, optionally combined with a mixture of a hydrocarbon such as petroleum jelly and an alkylphosphoric acid salt, sorbed onto a porous absorbent inorganic carrier comprising or consisting of anhydrous sodium carbonate, preferably light soda ash. When such granules are prepared by mixing and granulating in a high shear mixer/granulator, the addition of from 1 to 10 wt % water after mixing and granulation results in granules having improved flow properties.

  • Patent number: 6028048
    Abstract: Detergent compositions comprising aminodicarboxylic acid-N,N-dialkanoic acid or its salt (component A) and a synthetic surface active agent having microbial degradability (component B).In particular, in the case where an alkali salt of polyoxyalkylene alkylether acetic acid or alkyl polyglycoside is used as the surface active agent (component B), the detergent compositions exhibit excellent washing effect without forming metallic soap even in washing water with high hardness, and also show high solubility even under the condition of low water temperature, and have excellent microbial degradability. Thus, the detergent compositions are particularly suitable for washing fabrics. Further, in the case where synthetic anionic and/or nonionic surface active agent is used as the surface active agent (component B), influence of corrosion to light metals is small.
