Definitions
- the invention relates to solid detergent preparations for automatic dishwashing and a process for their production.
- typical cleaning agents can contain sodium citrate, citric acid, soda, sodium silicate, sodium hydrogen carbonate, sodium perborate, sodium percarbonate, bleach activators, surfactants and enzymes.
- the dosage form of the powder mixture that is often offered in conventional cleaning agents has the disadvantage that it is often very dusty during manufacture and use.
- powders tend to separate the individual components, which can have a negative effect on reproducible cleaning performance.
- sticking and caking of the individual base bodies can often not be ruled out, which has a negative effect on the free-flowing properties of the cleaning agents and thus their metering capacity and their storage stability. So far, this can only be prevented by complex, often multi-stage, drying processes.
- DE 39 26 253 discloses processes for the production of extrudates, in which a homogeneous, solid premix is extruded under pressure and the strand is cut to the predetermined pellet size after exiting the hole shape by means of a cutting device.
- the homogeneous and solid premix contains a plasticizer and / or lubricant, which causes the premix to become plastically softened and extrudable under pressure or under the entry of specific work.
- Preferred plasticizers and / or lubricants are surfactants and / or polymers, which are preferably used in liquid, pasty or gel-like preparation form.
- the premix can also contain powders and / or granules, the granules being obtained, inter alia, by granulation processes or also by conventional spray drying processes. After exiting the hole shape, the system is no longer subjected to shear forces and the viscosity of the system increases in such a way that the extruded strand can be cut to predeterminable extrudate dimensions.

- "low water” means a quantity of water which, depending on the water absorption capacity of the feed materials, makes an additional drying step unnecessary.
- the invention thus relates to a solid detergent preparation for machine dishwashing in the form of compacts in giant-shaped grain form, which are compressed to bulk densities of at least 700 g / l, containing solid ingredients which are at least partly of the class of builders, alkali carriers, oxygen bleaches and / or Bleach activators belong and continue to be at least partly liquid or plastically deformable substances (liquid phase) at temperatures above 30 ° C, which can belong to the class of surfactants, characterized in that the liquid phase contains at least one component below approx. 30 ° C in solid form a melting point of less than 60 ° C includes.

This can be done in an extruder, for example.
- the component used in the products according to the invention with a melting point of between 30 and 60 ° C. is present as a liquid confectioning agent in the course of the processing process and her Solidification after the end of processing contributes to the solidification of the resulting compacts. It is crucial that this component, even if it is mixed with other liquid components, solidifies, ie at least partially crystallizes out. It is assumed that the still liquid portions of the cooled liquid phase are absorbed in the pore volume of the solids, whereas the hardened portions contribute to solidification.

- final etherification with short-chain alkyl groups such as preferably the butyl group, can also give the class of "closed" alcohol ethoxylates, which can also be used in the context of the invention. Highly ethoxylated fatty alcohols or their mixtures with end-capped fatty alcohol ethoxylates are very particularly preferred for the purposes of the present invention.

- bleach activators are compounds which contain one or more N- or O-acyl groups, such as substances from the class of anhydrides, esters, imides and acylated imidazoles or oximes. Examples are tetraacetylethylenediamine TAED, tetraacetyimethylenediamine TAMD and tetraacetylhexylenediamine TAHD, but also pentaacetylglucose PAG, 1,5-diacetyl-2,2-dioxo-hexahydro-1, 3,5-triazine DADHT and isatoic anhydride ISA. Bleach activator proportions of between 1 and 5% by weight, based on the preparation as a whole, have proven useful for the present invention.

- the amount of water is preferably below 5% by weight, particularly preferably below 3% by weight and very particularly preferably below 2% by weight. Such a small amount of water, which no longer requires an additional drying step, can be very useful in controlling the plasticity of the mixture.
