Definitions
- the present invention relates to a detergent and cleaning agent Contains alkalizing agents and possibly other common ingredients.
- the controlled release of individual detergent components to be determined is advantageous from an economic and ecological point of view and accordingly subject to intensive research.
- One is playing important role in which order the soiling with the individual Ingredients come into contact, but also the interaction of individual Ingredients are important, especially the interplay of bleach and enzymatic cleaning.
- Detergent and bleach compositions containing a source of hydrogen peroxide and contain a peroxyacid bleach precursor (bleach activator) and in the Wash liquor provide an initial alkaline pH (pH 10-11), as well as the delayed release of acid in the wash liquor to bring about a lowered pH to arrive in the fleet are described in the prior art and for example in European patent applications EP-A-0 290 081 (Unilever) and EP-A-0 396 287 (Clorox) or EP 0 651 053 (P&G).
- alkalizing agents are bleaching agents such as Sodium percarbonate, which can be coated with a coating material, which slowly dissolves in water regardless of pH, while being special coated ingredient a bleach activator, preferably tetraacetylethylenediamine (TAED), is used.
- TAED tetraacetylethylenediamine
- the present invention was based on the object of a washing and cleaning agent to develop that through the targeted and defined release kinetics and Combination of ingredients during the wash cycle a pH shift from weakly acidic or neutral into the usual alkaline range, so that the soiling first in a weakly acidic to neutral environment and are then treated in an alkaline medium, especially in the case of low Washing temperatures to achieve an improvement in washing performance.
- the present invention relates to detergents and cleaning agents Alkalizing agent, characterized in that the alkalizing agent completely or is partially coated with a coating material or compounded so that this in the Wash liquor after a period t1 of 1 min. up to 25 min. at most 10% and after t1 plus 3 min. up to 30 min. is released to at least 90%.
- the alkalizing agent is preferably used in a period t1 of 3 minutes. up to 20 min. and particularly preferably from 5 min. up to 15 min. at most 10% and preferably after t1 plus 5 min. up to 15 min. and particularly preferably from 7 min. up to 10 min. at least 90% released.
- Alkalizing agents come in the field of detergents and cleaning agents known substances into consideration which have an alkaline reaction in water. It can be soluble Alkalizing agents, such as alkali carbonates and their hydrates and perhydrates, phosphates such as. Sodium tripolyphosphate, soluble silicates such as e.g. Water glasses, alkali hydroxides, Carboxylates or Na perborate can be used. Suitable examples are also also known as insoluble alkali silicates as builders, as described in more detail below become.
- To release the alkalizing agent according to the invention Set the defined period of time, it has proven to be advantageous, the solubility to be retarded by a suitable coating and / or by a coarseness.
- the release of the alkalizing agent in the period defined according to the invention it has proven to be suitable to use these agents with wrapping materials provided that dissolve in the wash liquor with a defined kinetics. According to them If possible, a step-shaped, ideally sudden, dissolution occurs Release of the coated alkali carrier.
- Fatty alcohols are preferred as coating materials or fatty acids, which may be mixed with other coating materials can.
- a mixture of fatty alcohols and aluminum stearate is an example called.
- envelope materials known from the prior art are as follows summarized in key words: magnesium sulfate and sodium hexaphosphate, Dihydrogen phosphate or pyrophosphates, phosphonic acids, sodium metaborate and - Silicate, water glass and sodium polyphosphate, sodium sulfate, and silicate, or Sodium bicarbonate, borax and magnesium sulfate, boric acid, but also in part organic components such as fat derivatives, paraffins and waxes (melting temperature of the compounds between 25 and 90 ° C), polyethylene glycols and fatty acid esters thereof with a molecular weight of 300 to 1,700, combinations with magnesium oxide, Vinyl chloride-ethylene copolymer emulsions or vinyl chloride-ethylene methacrylate copolymer emulsions. Polycarboxylates or other water-soluble polymers.
- the coating materials can be applied from the melt or from solutions or Dispersions take place, the solvent or emulsifier being evaporated Will get removed. Also application as a fine powder, for example by electrostatic techniques are possible, although this method is too irregular and poorly adhering coatings.
- the wrapping materials can be stirred, Mixing and pelletizers are applied to particles. However, one is preferred Application of the enveloping materials in a fluidized bed, at the same time one Size classification of the particles can be done. Should the wrapping materials under certain circumstances lead to sticky products, it may be useful to to coat coated alkalizing agents with finely divided substances ("Powdering"). All fine-particle substances can be used as powdering agents, other detergent ingredients such as builder substances are also used can. Preferred additional powdering agents are zeolites, silicates, polymeric polycarboxylates, carbonates, citrates, starch, cellulose derivatives, etc. used. Part of the buffer system, if present, can also be used for powdering become.
- the coating materials for the alkalizing agent are used in such amounts that that an optimal interaction of the individual components and thus an exact controlled release is enabled. Depending on the period within which the Release should be largely suppressed and depending on the size de coated Particles will measure the amount of shell material.
- Preferred Embodiments use less than 20% by weight wrapping material based on the Amount of coated particles, in particular less than 10% by weight Wrapping materials preferred.
- a preferred "physical" method to delay the alkalizing agent releasing is to make it worse compared to the other ingredients to provide soluble form. This can be done, for example, by varying the Particle size can be achieved because there are finely divided detergents or cleaning agents dissolve faster due to the larger surface. Also the A combination of different densities is preferred Way to realize different solubilities. For example powdery ingredients with more compacted, for example extruded, and so that slower soluble alkalizing agents can be combined.
- the "physical Release delay "within a molded body For this purpose, washing or detergent tablets are produced, which consist of several phases exist, where one phase is less compressed than another phase. The the more easily compressed phase breaks down more quickly into the previous one in the washing or cleaning cycle pressed premix, which increases the solubility to a harder pressed phase is increased.
- two-layer tablets are particularly preferred, where one layer is pressed more softly than the other, the hardest one Layer containing the alkalizing agent.
- the retardation of a phase also about a lower content of a de-integration aid contained in it can be achieved.
- the agents according to the invention can include a buffer system, nonionic and anionic surfactants, builders, bleaches and other common Components included.
- the agent according to the invention contains Buffer system. Due to the buffer system, the pH in the wash liquor is increased when the Detergent composition comparatively low, i.e. it is between 6 and 8, preferably between 6.3 and 7.7, particularly preferably between 6.5 and 7.5.

- Shaped bodies are produced in accordance with the state of the art Method. Usually the individual components, all or part can be pre-granulated, mixed dry and then shaped, in particular by pressing into tablets, using conventional methods can be used. For the production of moldings, the premix is in a so-called matrix between two stamps to form a solid compact condensed. This process, which is briefly referred to below as tabletting, is divided into four sections: dosing, compression (elastic deformation), plastic deformation and ejection.
- the premix is introduced into the die, the filling quantity and so that the weight and shape of the resulting molded body by the position of the lower stamp and the shape of the press tool can be determined.
- the constant dosing is preferred, even with high molding throughputs achieved by volumetric metering of the premix.
- the upper plunger touches the premix when tabletting and descends further of the lower stamp. With this compression, the particles of the premix pressed closer together, the void volume inside the filling between the stamps decreases continuously. From a certain position of the The upper stamp (and thus from a certain pressure on the premix) begins plastic deformation, in which the particles flow together and it to form the Shaped body comes.
- the premixed particles are crushed and it comes at even higher pressures to sinter the premix.
- the phase of elastic deformation is shortened more and more, so that the resulting shaped bodies have more or less large cavities can.
- the finished molded body is removed by the Lower stamp pressed out of the die and by subsequent ones Transport equipment transported away. At this point, only the weight of the Shaped body finally determined because the compacts due to physical processes (Stretching, crystallographic effects, cooling etc.) their shape and size still can change.
- Tableting takes place in commercially available tablet presses, which are basically or double stamps can be equipped. In the latter case, not only Upper stamp used to build up pressure, the lower stamp also moves during of the pressing process towards the upper punch, while the upper punch is down presses.
- Eccentric tablet presses are preferred for small production quantities used, in which the stamp or stamps are attached to an eccentric, the in turn is mounted on an axis with a certain rotational speed.

- the Matrix table and the stamp move around a common vertical Axis, the stamp with the help of rail-like cam tracks during circulation in the positions for filling, compression, plastic deformation and discharge to be brought.
- the stamp is necessary (filling, compacting, ejecting), these will be Curved tracks by additional low pressure pieces, low tension rails and Lifting lanes supported.
- the matrix is filled with a rigid one arranged feed device, the so-called filling shoe, which with a Storage container for the premix is connected.
- the pressure on the premix is individually adjustable via the press paths for upper and lower punches, whereby the Pressure build-up by rolling the stamp shaft heads past adjustable ones Print rolls happen.
- Rotary presses can also be used with two filling shoes to increase the throughput be provided, with only a semicircle to produce a tablet must be gone through.
- For the production of two- and multi-layer moldings several filling shoes arranged one behind the other without the slightly pressed first Layer is ejected before further filling. Through suitable process control In this way, coated and dot tablets can also be produced have onion-shell-like structure, with the top in the case of the point tablets the core or core layers is not covered and thus remains visible.
