Definitions
- the present invention relates to a process for the production of particulate detergents and / or cleaning agents which contain both enzymes and bleaching agents by granulating the oxidizing agent component and mixing with the particulate compound enzyme component and optionally further particulate components.
- the production of particulate detergents and cleaning agents can be carried out by mixing the individual particulate ingredients.
- this can, for example due to different particle sizes and particle densities, lead to segregation of the ingredients and thus inconsistent performance of the agent.
- Another difficulty arises from the fact that some ingredients of washing or cleaning agents are impaired in their effectiveness by the contact, which results from the mixing of the individual substances, with other ingredients of the same agent, or by contact with atmospheric oxygen or in the ambient air the water they contain will lose their effect.
- enzymes normally contained in detergents and cleaning agents which are inactivated or destroyed by contact with bleaching agent components which are also common in such detergents and which, after short storage, can no longer contribute to the washing or cleaning performance of the detergents.
- Conventional bleaching agents in the form of oxidizing agents based on oxygen are decomposed by atmospheric water or bleach activators are hydrolyzed by water and are then no longer available under the conditions of use.
- Spray drying as a very common process for the production of particulate detergents and cleaning agents, is not suitable because of the thermal sensitivity of the bleaching agents or the enzymes to help solve these problems.
- Granulation processes for the production of detergents or cleaning agents are known as an alternative to processes which have a spray drying step.
- the conversion of previously spray-dried detergent ingredients into granules is also known. Reference can be made, for example, to the method known from European patent application EP 0 339 996, in which granules consisting of detergent components and obtained by spray drying are introduced into a high-speed mixer / granulator and pulverized there at high speed by the mixing tools and the knife.
- the mixer then runs at a lower speed for the mixing tools and the knife, during which water is sprayed on as a granulating aid. After spraying, the mixer runs at a medium speed using mixing tools and knives to form granules from the solid and liquid components. After the granulation has ended, a finely divided amorphous sodium aluminum silicate is added to the mixer, the mixer being operated at a relatively slow speed of the mixing tools and the knife.
- EP 0 351 937 describes a method for producing a detergent composition with increased bulk density. The granulation and compaction is carried out in a high-speed mixer. After completion of the granulation, it is possible to add 0.2 to 5% by weight of amorphous or 3 to 12% by weight of crystalline aluminum silicate at a low mixer speed in order to improve the flowability, with no further granulation occurring. Similar processes, but with different detergent compositions, are described in EP 0 340 013.
- Another granulation process for producing granular detergents and cleaning agents is known from international patent application WO 93/23523.
- two-stage granulation is carried out in two mixers / granulators connected in series.
- the first, slow-running mixer 40% by weight to 100% by weight, based on the total amount of the solid and liquid constituents used, of the solid and liquid constituents are pregranulated.
- the second, high-speed running Mixer the pre-granulate from the first process stage is mixed with the remaining solid and / or liquid constituents and transferred into the finished granulate.
- German patent application DE 43 04 475 Another method for producing granulated detergents and cleaning agents is known from German patent application DE 43 04 475. This process is also carried out in two stages. In contrast to the processes already mentioned, in the first process stage there is no granulation or agglomeration, but only a mixing and loading of the added powder. In a second process step the starting materials from the first process step in a second mixer to be transferred, where the pulverfb 'shaped starting materials compacted by introduction of energy and the granules formed are rolled thereby compacting against each other. To stop the build-up roll granulation taking place here, a finely divided powder, for example zeolite powder such as zeolite NaA, is added to end the rolling process.
- zeolite powder such as zeolite NaA
