  • the binder used in the preparation of the additive so that preferred methods are characterized in that the detergent particles, based on their weight , with 0.1 to 10 wt .-% of one or more liquid at temperatures up to 40 ° C binder, preferably from the group of polyethylene glycols and polypropylene glycols, glycerol, glycerol carbonate, ethylene glycol, propylene glycol and propylene carbonate and perfume oils, paraffins, silicone oils and ethoxylated fatty alcohols , sprayed or doused and then powdered with the detergent and cleaning agent additives.
  • a blue dye (Supranol® Blue) was dissolved in 18 parts by weight of glycerol (86%).
  • glycerol 86%
  • zeolite X Wessalith® XD, Degussa, particle size: 100% ⁇ 50 ⁇ m
  • a green dye (Pigmosol® Green) was dissolved in 17 parts by weight of glycerol (86%).
  • glycerol 86%
  • Lödige 80 parts by weight of zeolite X (Wessalith® XD, Degussa, particle size: 100% ⁇ 50 microns) were placed and sprayed over a period of 2 minutes with the dye solution. The result was a finely divided, almost colorless, light green compound. If this compound is subsequently treated in the mixer for a further 3 minutes, the color impression intensifies and a green powder is formed.
  • a red dye (Sandolan® Rhodamine E-RD 400%) was dissolved in 19.5 parts by weight of glycerol (86%).
  • glycerol 86%
  • Lödige 80 parts by weight of zeolite X (Wessalith® XD, Degussa, particle size: 100% ⁇ 50 microns) were placed and sprayed over a period of 5 minutes with the dye solution. The result was a finely divided, purple-red compound.
  • zeolite X (Wessalith® XD, Degussa, particle size: 100% ⁇ 50 microns) and 5 wt .-% titanium dioxide (particle size: 100% ⁇ 50 mm) were introduced and mixed. 40 parts by weight of perfume oil were added to this mixture within 2 minutes. After three minutes of mixing, a pure white finely divided powder was obtained.
  • the compounds prepared under 1 to 4 can be mixed with conventional detergents and cleaning agents, wherein the use of the compounds as a powdering agent brings particular advantages.
  • extruded particles of a laundry detergent with 1 and 2 wt .-% of the compounds were powdered.
  • the dye additives obtained according to the invention had a homogeneous color distribution and were readily free-flowing, while the jetting of a dye solution yielded sticky particles with inhomogeneous color distribution.
  • washing and cleaning agent particles are powdered with the additive prepared under 6., very free-flowing products with a high degree of whiteness are obtained. Another advantage is the much more homogeneous distribution of perfume in the product.
