Definitions
- the present invention relates to a process for the production of pourable and free-flowing granular detergent components which contain an active substance which is liquid at room temperature and a finely divided carrier material for such an active substance, and the use of granules prepared in this way for the production of solid detergents and cleaning agents.
- Modern detergents and cleaning agents contain a large number of ingredients, which, in addition to the ingredients that are indispensable for the washing process, such as surfactants and builder materials, usually include other ingredients that contain such different active ingredient groups as foam regulators, graying inhibitors, "soil release” active ingredients, Bleaches, bleach activators and color transfer inhibitors can include.
- active ingredient groups such as foam regulators, graying inhibitors, "soil release” active ingredients, Bleaches, bleach activators and color transfer inhibitors can include.
- liquid ingredients in the case of solid agents in powder form must of course not exceed a certain upper limit, since otherwise the individual particles cake together, the pourability of the agent and its ability to be poured out of the packaging container are no longer ensured, and the user is able to dose and handle it significantly more difficult.
- Components that are liquid at room temperature are therefore usually incorporated into powdery compositions in the form of mixtures with solid, absorbent carrier materials.
- a large number of processes are available for producing such compounds from solid, powdered carrier material and liquid active ingredient. For example, it is possible to spray-dry aqueous slurries of carrier material and liquid active ingredient. This process is difficult if water-insoluble or water-dispersible substances are to be processed.
- An alternative manufacturing method is, for example, the application of liquids to carrier material particles moving in a mixer.
- active ingredients that are liquid at the temperature at which the carrier material particles are present
- there is a risk of agglomeration of the carrier material that is applied which leads to a not always desired enlargement of the particles leads, and the caking of the particles on the mixer wall.
- One approach to avoiding these dangers can be to use a fluidized bed of the carrier material to which the liquid is applied. It should be noted, however, that a fluidized bed cannot be produced from every substance suitable as a solid support material and often the agglomeration of the particles forming the fluidized bed cannot be completely prevented.
- the object of the present invention is to develop an alternative production process for granular constituents of detergents and cleaning agents which contain an active ingredient which is at least partially liquid at room temperature and a finely divided carrier material, in which these disadvantages are avoided as far as possible.
- the invention relates to a process for the production of bulk and free-flowing granular detergent constituents which contain an active substance which is at least partially liquid at room temperature and a finely divided carrier material for such an active substance, which is characterized in that the carrier material, which has an average particle size in Has a range of 3 ⁇ m to 0.5 mm, drops onto a rotating plate, where it is accelerated in the radial direction by blades attached to the top of the plate, and one passes through an annular gap nozzle that extends from the outer edge of the rotating plate and the surrounding plate Stator is formed, the liquid active ingredient applies to the particle stream.
- the invention preferably uses the Rotocoat® process measures known for processing completely different substances.
- Rotocoat® process and the device used are described, for example, in the information sheet "Sandvik Rotocoat® Process: solvent-free coating and agglomeration" from Sandvik Process Systems from 9/93.
- This process is a continuous coating process in which a powdered carrier material falls from above onto a horizontally mounted rotating plate. With the help of blades attached to the top of the plate, the powder is accelerated in the radial direction by the centrifugal force, so that an entrained flow is generated.
- Another object of the invention is therefore the use of a Rotocoat® device for applying detergent active ingredients which are at least partially liquid at room temperature to a finely divided carrier material.
- relatively large proportions, for example not more than 80% by weight and in particular up to 70% by weight, of the material to be applied can be tolerated in the form which is solid at room temperature, in particular if the component which is solid at room temperature is in liquid form at the processing temperature, that is to say when it enters the spray coater device.
- the component that is solid at room temperature does not or does not completely dissolve in the component that is liquid at room temperature even after melting, as is the case, for example, with solid paraffins and liquid silicone oils
- the mixture of the melted component that is solid at room temperature and the component that is liquid at room temperature should be used until as short as possible before entering the spray coater device in order to achieve the most uniform possible application of the heterogeneous coating composition to the carrier material.
- solvents that is to say more or less volatile substances, which have to be removed by heating them after the coating material has been applied, is not preferred.
- particulate carrier material is not critical. Both inorganic detergent ingredients such as alkali carbonates,
- alkali salts mentioned sodium is the preferred cation, although the potassium or lithium salts can also be used.
- the average particle size of the carrier material is preferably in the range from 3 ⁇ m to 100 ⁇ m, in particular in the range from 30 ⁇ m to 100 ⁇ m.
- the carrier material has no more than 15% by weight of particles smaller than 10 ⁇ m, 10% by weight to 50% by weight of particles in the range from 10 ⁇ m to 50 ⁇ m, 30% by weight. % to 80% by weight of particles in the range greater than 50 ⁇ m to 100 ⁇ m and 5% by weight to 30% by weight of particles in the range greater than 100 ⁇ m.
- the carrier material has 5% by weight to 20% by weight of particles smaller than 10 ⁇ m, 20% by weight to 40% by weight of particles in the range from 10 ⁇ m to 50 ⁇ m, 20% by weight to 40% by weight of particles in the range greater than 50 ⁇ m to 100 ⁇ m and 20% by weight to 50% by weight of particles in the range greater than 100 ⁇ m.
- Extremely finely divided substances for example the detergent zeolites mentioned, can be agglomerated in a known manner, for example by spray drying, to particle sizes in the preferred range before use in the process according to the invention. Since the wetting of the concrete individual particles is achieved by the process according to the invention, the average particle size and the particle size distribution of the finished granulate normally do not deviate significantly from that of the carrier material used.
- Carrier materials which are in non-crystalline form are preferred.
- the active substance which is liquid at room temperature and is to be applied to the carrier material is preferably a surfactant, a dirt-releasing polymer, a foam-inhibiting paraffin oil or a foam-inhibiting silicone oil, for example a dimethylpolysiloxane. Mixtures of these active ingredients are also possible.

- European patent application EP 272 033 discloses polyesters with poly-propylene terephthalate and polyoxyethylene terephthalate units which are at least partially end-capped by C -alkyl or acyl radicals.
- European patent EP 274 907 describes sulfoethyl end group-capped terephthalate-containing soil release polyesters.
- Foam-inhibiting paraffin oils which can be used in the process according to the invention and which can be present in a mixture with paraffin waxes are generally complex substance mixtures without a sharp melting point.
- the melting range is usually determined by differential thermal analysis (DTA), as described in " The Analyst "£ 2 (1962), 420, and / or the freezing point. This is the temperature at which the paraffin changes from the liquid to the solid state by slow cooling.
- Paraffins with less than 17 carbon atoms are not usable according to the invention, their proportion in the paraffm oil mixture should therefore be as low as possible and is preferably below the limit that can be significantly measured using conventional analytical methods, for example gas chromatography.

The consequence of this is that the paraffins are flowable and pumpable at temperatures down to at least 70 ° C., preferably down to at least 60 ° C. It is also important to ensure that the paraffins do not contain any volatile components.
- Paraffin waxes contain less than 1% by weight, in particular less than 0.5% by weight, of parts which can be evaporated at 110 ° C. and normal pressure.
