Definitions
- the present invention relates to a method for producing a multiphase detergent tablet and the specific detergent tablets produced by this method.
- Washing or cleaning agents are offered to the consumer in the form of solid or liquid products.
- the solid and liquid detergents or cleaning agents were originally packaged in the form of larger containers (e.g. bags or bottles). These large containers have recently been replaced, at least in part, by pre-metered forms of assembly (“unit dose”). These dosing units are, for example, tablets or water-soluble bags.
- the metering units can in turn be configured as single or multi-phase.
- Multi-phase detergent or cleaning agent dosing units offer manufacturers and consumers a number of advantages over single-phase dosing units.
- incompatible ingredients can be separated from each other.
- multi-phase nature of a dosing unit can be used, for example, to visualize and communicate the different aspects of its washing or cleaning action.
- the dosing units can be packaged in a water-insoluble film or a water-soluble film. While the water-insoluble film must be removed by the consumer before the metering unit is used, the film that is soluble when it is introduced into the aqueous washing or cleaning liquor can remain on the metering unit. This simplified handling could possibly have leaky foil seams and a product haptic, which may be perceived as unpleasant, as disadvantages.
- the task was to provide a multi-phase dosing unit for detergents or cleaning agents, which is characterized by good dissolution behavior, an attractive product appearance and product feel.
- the dosing unit should continue to have good storage and transportability even under high mechanical loads.
- a first subject matter of the claim is a method for producing a multiphase detergent tablet, comprising the steps

- fragrances especially encapsulated fragrances
- Fabric softeners especially cationic surfactants and cationic polymers
- Dyes especially textile dyes.
- a cleaning agent is a composition that is suitable for cleaning and maintaining hard surfaces and contains at least one surface-cleaning or surface-maintaining active substance.
- Exemplary surface-cleaning active substances are:
- Surfactants especially nonionic or anionic surfactants,
- Builders in particular citrates, hydrogen carbonates, carbonates, silicates and water-softening polymers,

- Exemplary surface care active substances are:
- Corrosion inhibitors especially zinc salts
- Water repellents in particular polymeric water repellents.
