Definitions
- the present invention relates to a process for the production of moldings, in particular of detergent tablets.
- Detergent tablets are widely described in the prior art are becoming increasingly popular with consumers because of the simple dosage.
- Tableted cleaning agents have a number of products compared to powder products of advantages: They are easier to dose and handle and because of their compact structure Advantages in storage and transport.
- the developers are involved early on tablet-shaped products came up with the idea of different compositions Areas of the molded body certain ingredients only under defined conditions to be released in the washing or cleaning cycle in order to ensure cleaning success improve.
- In addition to those well known from pharmacy Core / shell tablets and ring / core tablets, in particular multi-layer molded articles prevailed today for many areas of washing and cleaning or hygiene Tobe offered.
- Multi-phase cleaning tablets for the toilet are described for example in EP 055 100 (Jeyes Group).
- This document discloses toilet block detergents which comprise a molded body of a slowly soluble detergent composition in which a bleach tablet is embedded.
- this document discloses the most varied forms of configuration of multiphase shaped bodies.
- the moldings are produced either by inserting a compressed bleach tablet into a mold and pouring the detergent composition into this tablet, or by pouring part of the detergent composition into the mold, followed by inserting the compressed bleach tablet and possibly subsequently pouring over it with another detergent composition.
- EP 481 547 also describes multi-phase detergent tablets which are to be used for automatic dishwashing.
- These shaped bodies have the shape of core / shell tablets and are produced by gradually compressing the components: first, a bleaching composition is pressed into a shaped body, which is placed in a matrix half-filled with a polymer composition, which is then filled with another polymer composition and is pressed to form a bleaching agent body provided with a polymer jacket. The process is then repeated with an alkaline detergent composition, so that a three-phase shaped body results.
- coated cores should both have a stable and adherent coating and should be able to be fed at high speeds. It has now been found that certain core shapes can then be precisely fed in large numbers and at high speeds.
- the invention relates to a method for producing detergent tablets, in the case of the prefabricated shaped body (“cores”), tabletting mixtures and / or prefabricated tablets (“base tablets”) are supplied, the cores have a biconvex shape, the convex surfaces being capped so that they each lead to a horizontal plateau.

Methods according to the invention are preferred here in which the radius of curvature the convex surfaces 0.5 to 5 times, preferably one to 3 times and in particular 1.5 to twice the diameter of the cores.
- the size of the plateau depends on the absolute size of the entire core. Methods according to the invention are preferred here, in which the diameter of the plateaus is 0.1 to 0.7 times, preferably 0.2 to 0.6 times, particularly preferably 0.25 to 0.5 times and in particular 0.3 to Is 0.4 times the diameter of the cores.
- the two convex surfaces can meet directly; but it is also possible that the connection is made via a vertical edge surface, which the core a wider Gives contact surface when in contact with other cores.
- the cores additionally have a vertical edge surface, the Height 0.1 to 0.9 times, preferably 0.2 to 0.7 times, particularly preferred 0.25 to 0.6 times and in particular 0.3 to 0.5 times the total tablet height is.
- a shaped body (“core”) is produced, which then either together with a particulate premix to one Multiphase tablet pressed or fed to a cavity of a pre-compressed molded body becomes.
- the method according to the invention also allows several to be pressed Core moldings together with one or more particulate premixes, whereby both of the recipe variability as well as of the optical differentiation the resulting molded body creates almost unlimited possibilities. Likewise, the dosing of several cores in several cavities of a basic shaped body possible without any problems.
- core molded article characterizes in the context of the present invention a molded body, which are supplied to the method according to the invention in a targeted manner can.
- this core molding differs from the particulate premix due to its larger spatial extension compared to the individual particles of the premix and on the other hand in that its placement in the matrix of Tablet press not in an arbitrary manner (i.e. in bulk like the particulate Premix), but in a defined and orderly movement.
- the mass of the core molding can vary on the overall molding.
- the mass of the core molding a) is more than 0.5 g, preferably more than 1 g and in particular more than 2 g.
- the core molding a) has a base area of at least 50 mm 2 , preferably of at least 100 mm 2 and in particular of at least 150 mm 2 .

- the process end product of the process according to the invention contains more than one Shaped core, the information given above preferably applies to all Core moldings individually, i.e. not for the sum of the core moldings, but for everyone individual.
- the core moldings are made in preferred process variants coated or treated with encapsulants. This can be done using common Methods of coating bodies are used, in particular that Immersing the body in or spraying the body with a solution of the coating materials.
- Methods are preferred which use solutions which are as concentrated as possible. Independently whether a dipping process or another type of application (spraying etc.) is selected, methods according to the invention are preferred in which the solution based on their weight at least 25% by weight, preferably at least 30 % By weight, particularly preferably at least 35% by weight and in particular at least 40 Wt .-% coating material contains.
- the substances are applied as a coating to the core molding, the substances e.g. sprayed on as a melt or in the form of a solution or dispersion or the mixture can be immersed in the melt, solution or dispersion or mixed in a suitable mixer. Coating too in a fluid bed apparatus is possible. When spraying, all are suitable for Pharmaceutical and food technology established processes for the production of coated Tablets, capsules and particles.
- the polymer suspension or solution is either sprayed discontinuously in small portions, the particles e.g. transported on a conveyor belt through a liquid veil and then in the Airflow can be dried or continuously while drying by the injected air flow in fluidized bed, fluidized bed or flight bed wrapping devices sprayed.
- the coating process is also conceivable if the coating syrups are used for coating materials are added in a sufficiently high concentration.
- the application a second layer may be carried out analogously.
- the aqueous solution can be further with water miscible volatile solvents are added.
- water miscible volatile solvents come in particular from the group of alcohols, ethanol, n-propanol and iso-propanol being preferred are. For cost reasons, ethanol and isopropanol are particularly recommended.
- aqueous solutions can be done in different ways are familiar to the expert.
- the solution can be created using a pump system a nozzle where the solution is atomized by the high shear forces becomes.
- the resulting spray mist can then be applied to the moldings to be coated are directed, which subsequently optionally with the help of suitable measures (e.g. blowing with heated air).
- suitable measures e.g. blowing with heated air
- a two-component nozzle used and used as carrier gas compressed air.
- Protecting oxidation or other interactions with the carrier gas can also other carrier gases such as nitrogen, noble gases, lower alkanes or ethers be used.

- Solvent or solvent mixture from the group water, ethanol, propanol, iso-propanol, n-heptane and their mixtures with the aid of inert blowing agents from the Group nitrogen, nitrous oxide, propane, butane, dimethyl ether and mixtures thereof sprayed onto the moldings.
- suitable coating materials are (in particular water-soluble polymers) also waxes.
- waxes Under “Grow” a number of natural ones become or artificially obtained substances that are usually above 35 ° C without decomposition melt and relatively low viscosity a little above the melting point and are not stringy. They have a strongly temperature-dependent consistency and Solubility. According to their origin, the waxes are divided into three groups, the natural ones Waxes, chemically modified waxes and synthetic waxes.
- Natural waxes include, for example, vegetable waxes such as candelilla wax, Carnauba wax, Japanese wax, esparto grass wax, cork wax, guaruma wax, Rice germ oil wax, sugar cane wax, ouricury wax, or montan wax, animal waxes such as beeswax, shellac wax, walrus, lanolin (wool wax), or pretzel fat, Mineral waxes such as ceresin or ozokerite (earth wax), or petrochemical waxes such as Petrolatum, paraffin waxes or micro waxes.

- animal waxes such as beeswax, shellac wax, walrus, lanolin (wool wax), or pretzel fat
- Mineral waxes
- the chemically modified waxes include hard waxes such as Montanester waxes, Sassol waxes or hydrogenated jojoba waxes.
- Synthetic waxes generally include polyalkylene waxes or Understand polyalkylene glycol waxes. Can also be used as coating materials Compounds from other classes of substances which meet the requirements mentioned with regard to the Meet softening point. Suitable synthetic compounds have been found for example higher esters of phthalic acid, especially dicyclohexyl phthalate, the is commercially available under the name Unimoll® 66 (Bayer AG). Suitable are also synthetically produced waxes from lower carboxylic acids and fatty alcohols, for example Dimyristyl Tartrate, which is sold under the name Cosmacol® ETLP (Condea) is available. Conversely, synthetic or semi-synthetic esters from lower are also Alcohols with fatty acids from native sources can be used.
- Tegin® 90 Goldschmidt
- Shellac for example Shellac-KPS-Dreiring-SP (Kalkhoff GmbH) is another Substance can be used.
- the waxes within the scope of the present invention are also, for example the so-called wax alcohols.
- Wax alcohols are higher molecular weight, water-insoluble fatty alcohols usually with about 22 to 40 carbon atoms.
- the Wax alcohols for example, come in the form of wax esters of higher molecular weight Fatty acids (wax acids) as the main component of many natural waxes.
- examples for Wax alcohols are lignoceryl alcohol (1-tetracosanol), cetyl alcohol, myristyl alcohol or Melissyl.
- the coating can optionally also contain wool wax alcohols, what is meant by triterpenoid and steroid alcohols, for example lanolin, that for example, is available under the trade name Argowax® (Pamentier & Co). Can also be used at least partially as part of the coating in the frame of the present invention but fatty acid glycerol esters or fatty acid alkanolamides optionally also water-insoluble or only slightly water-soluble Polyalkylene glycol.
- wool wax alcohols what is meant by triterpenoid and steroid alcohols, for example lanolin, that for example, is available under the trade name Argowax® (Pamentier & Co).
- fatty acid glycerol esters or fatty acid alkanolamides optionally also water-insoluble or only slightly water-soluble Polyalkylene glycol.
- Water-soluble polymers in the sense of the invention are those polymers which are at room temperature are more than 2.5% by weight soluble in water.
- the coating of the core moldings can preferably be functionalized, i.e. give the molded body a certain resolution kinetics. It is through targeted choice of the Coating material also possible that the coating only to a predetermined Time or given conditions dissolves and the components of the core molding releases. Here in particular so-called LCST substances have been found Coating materials proven.
- LCST substances are substances that are active at low temperatures have better solubility than at higher temperatures. They are also called substances designated with the lower critical separation temperature. These substances are usually polymers.
