  • the object of the present invention was to provide a small component compound which can be added directly to the finished detergent and cleaning agent in the preparation of surfactant granules and which shows no tendency to segregate. Furthermore, a manufacturing method for such a small component compound should be provided which is inexpensive, universally applicable and can be carried out without great outlay on equipment and with little cleaning effort.

  • a solid detergent and cleaning agent additive in which a solid detergent and cleaning agent ingredient from the group of enzymes, pH adjusters, fluorescent agents, dyes, foam inhibitors, anti-redeposition agents, optical brighteners, graying inhibitors, color transfer inhibitors and Corrosion inhibitors and mixtures with carrier materials with an oil absorption capacity of at least 20 g / 100 g are mixed and one or more binders liquid at temperatures up to 40 ° C. are applied to the agitated mixture.
  • the embodiments identified above as preferred are again preferred.
  • the carrier material in amounts of 40 to 98.9% by weight, preferably 50 to 95% by weight, particularly preferably 55 to 85% by weight and in particular 60 up to 80% by weight, with substances from the group of silicates and / or aluminum silicates being preferred and it being particularly preferred that all particles of the support material be less than 200 ⁇ m, preferably less than 100 ⁇ m, particularly preferably less than 75 ⁇ m and in particular less than 50 ⁇ m, the binder (s) which are liquid at temperatures up to 40 ° C.
  • detergent and cleaning agent additives according to the invention described above which can be obtained by the likewise described inventive processes, can be added to detergents and cleaning agents.
  • Another object of the present invention is therefore the use of detergent and cleaning agent additives which contain 40 to 98.9% by weight of carrier material with an oil absorption capacity of at least 20g / 100g, 1 to 50% by weight of one or more at temperatures up to 40 ° C liquid binder, 0.1 to 40 wt .-% of a detergent ingredient from the group of enzymes, pH adjusters, fluorescent agents, dyes, foam inhibitors, anti-redeposition agents, optical brighteners, graying inhibitors, color transfer agents inhibitors and corrosion inhibitors and mixtures thereof contain, as an additive in detergents.
  • washing and cleaning agent additives according to the invention can be added to the washing and cleaning agents by simple mixing. However, it is preferred according to the invention to use the additives as powdering agents, so that in preferred uses the washing and cleaning agent additives are used as powdering agents for coarse-grained washing and cleaning agent particles.
  • the particles powdered in this way can be processed further, for example - optionally after mixing with further detergent and cleaning agent ingredients - in a manner known per se to be pressed into detergent tablets.
  • Another object of the invention is therefore a process for the production of detergents and cleaning agents, in which detergent and cleaning agent particles are produced in a manner known per se, which are mixed with detergent and cleaning agent additives, which are 40 to 98.9% by weight.
  • Carrier material with an oil absorption capacity of at least 20g / 100g, 1 to 50% by weight of one or more binders liquid at temperatures up to 40 ° C, 0.1 to 40% by weight of a detergent and cleaning agent ingredient from the group of enzymes , pH-adjusting agents, fluorescent agents, dyes, foam inhibitors, anti-redeposition agents, optical brighteners, graying inhibitors, color transfer inhibitors and corrosion inhibitors and mixtures thereof are powdered.
  • the detergent and cleaning agent particles have a particle size distribution in which at least 75% by weight, preferably at least 85% by weight and in particular more than 95% by weight of the particles have particle sizes between 200 and 2000 ⁇ m, preferably between 400 and 1600 ⁇ m and in particular between 600 and 1200 ⁇ m.
  • the additives according to the invention, which are used as powdering agents, are preferably finely divided.
  • the detergent and cleaning agent additives have a particle size distribution in which at least 75% by weight, preferably at least 85% by weight and in particular more than 95% % By weight of the particles have particle sizes between 1 and 200 ⁇ m, preferably between 2 and 100 ⁇ m and in particular between 5 and 50 ⁇ m.
  • the binders used in the production of the additive are used as adhesion promoters between detergent and detergent particles and additive (powdering agent), so that preferred processes are characterized in that the detergent and detergent particles are based on their weight , with 0.1 to 10% by weight of one or more binders which are liquid at temperatures up to 40 ° C., preferably from the group of polyethylene glycols and polypropylene glycols, glycerol, glycerol carbonate, ethylene glycol, propylene glycol and propylene carbonate, as well as perfume oils, paraffins, silicone oils and ethoxylated fatty alcohols , sprayed or sprayed and then powdered with the detergent and cleaning agent additives.
  • a red dye (Sandolan Rhodamine ® E-RD 400%) were dissolved in 19.5 parts by weight of glycerol (86% strength). (Wessalith XD ®, Degussa, particle size: 100% ⁇ 50 microns) in a 20 liter Lödige ploughshare mixer from 80 parts by weight zeolite X were introduced and sprayed over a period of 5 minutes by the dye solution. A finely divided, violet-red compound was created. 4. Preparation of a dye additive
  • the Lödige mixer chopper was used in all of the examples.
  • the compounds produced under 1 to 4 can be added to conventional washing and cleaning agents, the use of the compounds as powdering agents having particular advantages.
  • extruded particles of a textile detergent were each powdered with 1 or 2% by weight of the compounds according to the invention.
  • the dye additives obtained according to the invention had a homogeneous color distribution and were easy to travel, while spraying a dye solution gave sticky particles with an inhomogeneous color distribution.
