Definitions
- the present invention relates to detergent tablets.
- the present invention relates to printed detergent tablets with specific surface properties, detergent supply forms which comprise these detergent tablets, and washing and cleaning methods using these detergent tablets.
- the detergent tablets also usually have coatings made of film materials, which, however, in the case of detergent tablets can be water-soluble or water-insoluble, with the water-insoluble film packaging having to be removed by the consumer before the detergent tablet can be used.
- Both water-soluble and water-insoluble film packaging offer the manufacturers of the corresponding dosing units the opportunity to provide the washing or cleaning agents with imprints such as product designations, product information, company names or advertising messages and symbols.
- these advantageous properties of the film packaging are offset by an increased consumption of packaging materials.
- Water-soluble packaging films which are not removed by the consumer before the detergent tablets are used, also delay the dissolution of the tablets and reduce their product performance, especially in short or cold washing processes.
- the application was based on the object of providing detergent portion units that can be produced using simplified processes, have high product and storage stability, can be made up easily using very small amounts of packaging materials and are an appealing olfactory, visual and/or haptic appeal.
- the detergent portion units should have a high product performance and be easy and safe to handle for the consumer.
- a detergent tablet with a printed phase consisting of a compressed particulate premix is suitable for solving these problems - the particulate premix has a particle size distribution in which at least 60% by weight of the particles have a particle size between 100 gm and 900 gm;
- L*max ranges from 85 to 100
- a*max ranges from -3 to +5
- b*max ranges from +5 to -15.
- both the particle size distribution of the particulate premix used to produce the tablet and the degree of whiteness of the tablets produced from this premix affect the perceptibility and durability of the printing.
- both the absolute size of the particles and the proportion by weight of particles of a certain size are of influence.
- the particulate premix has a particle size distribution in which at least 70% by weight of the particles, preferably at least 80% by weight of the particles and in particular at least 90% by weight of the particles have a particle size between 100 gm and 900 gm. It is also preferred if the particulate premix has a particle size distribution in which at least 60% by weight of the particles have a particle size between 200 ⁇ m and 800 ⁇ m, preferably between 250 ⁇ m and 750 ⁇ m.

- Exemplary phases are tablet layers.
- the detergent tablet has two or more layers. While the production of the tablets tends to become more complex with an increasing number of layers, a tablet design with two or more layers simultaneously increases the degrees of freedom with regard to the particle sizes and the degree of whiteness of the ingredients used in the detergent tablet, since the particle sizes and the degree of whiteness in the non-printed Layers may deviate from the particle sizes and the whiteness of the printed layer.
- the detergent tablet has two layers which differ in terms of their average particle size D50 and the layer with the lower average particle size D50 has printing.
