  • tableting has an outstanding role; in the latter case, in the area of detergents or cleaning agents, mainly portions are used which are surrounded by packaging made of water-soluble materials.
  • Tableted detergents and cleaning agents have a number of advantages over powdered ones: They are easier to dose and handle and, thanks to their compact structure, have advantages during storage and transport. Detergent tablets are consequently also extensively described in the patent literature. A problem that occurs again and again when using shaped articles which are active in washing and cleaning is the insufficient rate of disintegration and dissolution of the shaped articles under conditions of use. Since sufficiently stable, i.e.
  • Shaped and unbreakable moldings can only be produced by relatively high pressure, there is a strong compression of the mold components and a consequent delayed disintegration of the mold in the aqueous liquor and thus to a slow release of the active substances in the washing or cleaning process ,
  • the delayed disintegration of the moldings has the further disadvantage that many detergent tablets cannot be washed in via the induction chamber of household washing machines, since the tablets do not disintegrate into secondary particles that are small enough to pass from the induction chamber into the washing drum in a sufficiently rapid time to be washed in.

  • Effect dyes can also be used, for example those which vary their color depending on the viewing angle. Pigments can also be used, and special optical effects can be achieved, for example, by using pearlescent pigments.
  • Pearlescent pigments are gloss pigments that have the shine as an additional property compared to other pigments. They are flat, small, thin platelets with relatively large diameters and smooth surfaces. Their characteristic properties of the flat structure, the high refractive index and the transparency create effects in transparent media as a result of the multiple reflection of light, which are equivalent to the gloss of pearls or mother-of-pearl. They can also achieve metal and similar effects without the disadvantages observed with metals and metal alloys.

  • the pigments are non-flammable and not self-igniting. They do not conduct the electrical current and tolerate temperatures up to approx. 800 ° C, which makes them particularly suitable for incorporation into the melt.
  • Pearlescent pigments are supplied as a dry powder. For special applications, pigments can also be offered as pastes or specially modified.
  • Interference pigments represent a further class. Interference is the superposition of waves: As with the waves that are created in the water by throwing in two stones, certain waves are amplified during the overlay and others are extinguished or weakened. The waves are amplified whenever Wellenberg meets Wellenberg. Wellenberg auf Wellental results in a weakening or extinction.
  • Classic pearlescent pigments known under the name Iriodin ® from Merck KGaA, consist of a mica plate as a carrier. This is encased by a heavy-breaking metal oxide such as titanium dioxide or iron oxide. Depending on the structure of the pigments, different colors result: Silver-white and whitish-colored pearlescent pigments are created by coating with titanium dioxide, reddish-copper by coating with iron oxide. Combining both metal oxides gives gold-yellow pigments. Green pigments can also be produced if titanium dioxide and chromium (3) oxide are used together. In addition to this body color, these pigments also show an interference color.
  • BASF AG went another way to coat mica and aluminum flakes: iron oxide was applied using a CVD process. Especially in the red and gold range these pigments with the trade name Paliocrom ® show interesting color impressions and with aluminum as a carrier they offer high hiding power.
  • the Si0 2 flakes are coated with highly refractive materials (e.g. Ti0 2 , Fe 2 0 3 ), in a process comparable to the proven manufacturing process for mica pigments. Thereby highly pigmented effect pigments are created, in which different color impressions are obtained depending on the respective viewing angle (color change). The simultaneous transparency gives the stylist a wide styling potential.
  • highly refractive materials e.g. Ti0 2 , Fe 2 0 3
  • Flex Products and BASF AG offer opaque pigments with color changes.
  • Flex's pigments which are marketed under the name Chromaflair ® , have an opaque aluminum layer as the central layer, which is surrounded by a magnesium fluoride layer and a semi-transparent metal layer. All three materials are colorless in themselves, the color is generated by interference and absorption of light. The pigments show a strong, almost abrupt color change and are not transparent due to the opaque metal layer.
  • Color Variable Pigments from BASF (Variocrom ® ) are multi-layer pigments that contain a reflective substrate such as aluminum or iron oxide platelets), a low-refractive interlayer (Si0 2 ) and an outer, selectively reflective layer made of iron oxide. In the pure shade, these pigments show brilliant color effects from bluish red to greenish gold. By combining with classic absorption pigments, color changes can be set in the entire color space.

If, for example, a tablet is included in the wall, which accounts for only 5% of the total weight of the agents according to the invention, the dye concentration in this tablet can be in the percent or even to reach into the percentage range.

  • Appropriate process management and selection of the materials can ensure that the mixture first solidifies on the wall of the mold.

Abstract

L'invention concerne des agents sous forme de portions, qui présentent d'une part les avantages de corps moulés et permettent d'autre part d'obtenir l'attrait esthétique de la structure chromatique et de la conformation d'emballages polymères, et induisent de ce fait une très bonne acceptance des utilisateurs. Lesdits agents comprennent un élément creux formé d'au moins une matière fondue solidifiée, ainsi que d'au moins un autre corps solide, ce dernier figurant sous forme moulée, au moins proportionnellement, dans la paroi de l'élément creux.
