Definitions
- the present invention relates to a composition for use in a water reservoir in the kitchen or sanitary area.
- compositions are known in different forms for different purposes, for example for decalcifying coffee machines or for cleaning and decalcifying toilets as an additive to the cistern.
- the aim of the present invention was to enable the simultaneous metering in of substances which may not be fully compatible when used simultaneously and which unfold their function (s) at differently defined times.
- detergent tablets for use as detergents are known, in which, among other things, it is provided to combine two components with different functionality.
- a structure is provided from an enveloping shell, which is composed, for example, of two shell halves, which consist of a cleaning agent, and a cavity enclosed by the shells, which contains additives such as plasticizers, whitening agents, etc.
- British Patent 1,390,503 discloses a liquid detergent which contains capsules which are insoluble in the composition but which release their contents when the composition is diluted with water. This goal is achieved in that the capsules are coated with a substance which has poor solubility in water solutions with high ionic strength, but becomes soluble when the ionic strength is reduced by dilution. It is pointed out that this technique can be used to include materials in the liquid detergent that are unstable in the liquid detergent itself or would create instability if added directly. te. It is also proposed to use this technique to delay the release of a specific substance.
- U.S. Patent 4,082,678 describes a tissue conditioning product which comprises a closed container which contains a releasable agent which serves to render an inner container, which is normally water-soluble or water-dispersible, located in the container insoluble or non-dispersible in water. wherein the inner container contains a tissue conditioning agent.
- the pH-sensitive coating is a copolymer of the following monomers:
- R is hydrogen or a methyl group
- R 1 and R 2 are each an alkyl group with 1-3 carbon atoms and x is an integer from 1-4;
- the polymers described are said to be insoluble at pH 9.5 or more and to become soluble at pH 8.5 or less.
- Different ingredients of detergent compositions are described, which can be coated successfully and effectively by the polymers described.
- the aim of the invention described there is to protect substances that are only supposed to develop their function in the rinse cycle until the beginning and then to release them as soon as possible.
- a disadvantage of the solution described in these Japanese patent applications is that the coated particles are in direct contact with non-alkaline,
- a washing aid which is surrounded by a water-soluble coating which is obtained by mixing polyvinyl acetal dialkylaminoacetate and at least one organic acid which is solid at room temperature.
- This protective covering is intended to protect the washing aid during the main wash cycle and to release it during the rinse cycles.
- the described compound reacts to the change in pH between the main wash and the rinse cycle.
- the protective covering may become detached at the beginning of the washing cycle.
- European patent application EP 0 481 547 A1 discloses multi-layer dishwasher detergent tablets with a core, a separating layer surrounding the core and an outer layer for the sequential release of the contents of the different layers. Basically, two tasks are to be solved with this tablet, namely 1) incompatible materials can be formulated together in a single tablet and released at different times in order to influence one another avoid; and 2) Compositions that are designed to perform their functions at different times can be formulated in a single tablet.
- a major disadvantage of this prior art is that the temperature and / or especially the contact time with the washing solution is used as a triggering factor for the initiation of the dissolution of the coating layer, which therefore clearly limits the practical applicability of the products described.
- PCT application WO 95/29982 discloses a delayed-release machine dishwashing detergent in the form of a non-ionic surfactant, this non-ionic surfactant, together with an inorganic builder salt, forming a core particle which is provided with a wax-like coating to compensate for the delayed release Ensure release.
- This coating is a substance that does not melt at the working temperatures that can be found in the cleaning cycle, but is chemically disintegrated so gradually at alkaline pH that an effective amount of the rinse aid remains at the end of the main cleaning cycle and is transferred to the rinse cycle.
- the disadvantage of this is that the coating is made soluble by chemical saponification at alkaline pHs, so that the point in time at which the rinse aid substance is released from the core is a function of both the temperature and the length of the main cleaning cycle.
- the patent application does not contain any teaching on how to formulate a product with which the rinse aid is only released in the rinse cycle in all washing programs of every device type. After all, the product is a mixture of granular detergent and granular rinse aid particles.

- Figure 1 shows a first embodiment of the composition according to the invention in cross section.
- Fig. 5 shows a fifth embodiment of a composition according to the invention in cross section.
- Fig. 1 shows a tablet 1, which consists of two half-tablets 2 and 3, which may have different or the same composition.
- An approximately hemispherical recess 4 or 5 can be seen approximately in the center of both half-tablets, which when the tablet 1 is joined together result in an approximately spherical cavity.
- particle 6 can also completely fill the entire cavity of the tablet and rest on the walls thereof. If the inside diameter of the cavity is slightly larger than the outside diameter of the particle 6, this can either be loosely received in the cavity or fixed by an adhesive placed in the gap.
- the surface of the particle is at most partially in direct contact with the surface of the surrounding Basic composition of the tablet is available. This can be done in the ways specifically described in this application, but also in any other way with which the intended purpose is achieved. Examples are the loose arrangement of a smaller particle in a larger cavity, the fixing of a smaller particle in the larger cavity in such a way that there is no or only partial contact between the particle and the base composition, the application of a protective coating over the covering of the core according to the invention Etc..
- the term "local environment" as used in connection with the particle according to the invention is intended to denote the immediate environment around this particle.
- the concentration of the specific compound in this local environment of the particle is the determining factor for its stability. In the preferred embodiments in tablet form, this concentration in the local environment of the particle is determined at least until the tablet is essentially completely dissolved by molecules dissolving from it.
- the origin of the "specific compound” is therefore preferably - at least in a first phase after addition to the water supply to the water reservoir - a compound from the basic composition forming the tablet or is generated by it in the surrounding medium. In the most typical case, these are OH " ions (in the case of basic cleaning agents) or H + ions (in the case of acidic decalcifying agents), the concentration of which can be expressed in both cases as a pH value.
- a conventional adhesive can be used to fix the particle in the cavity, but also other compositions and agents that serve the same purpose, for example mechanical fixation, such as e.g. sufficient friction between the tablet and particles in at least some places or a plug connection between the tablet and particles.
- mechanical fixation such as e.g. sufficient friction between the tablet and particles in at least some places or a plug connection between the tablet and particles.
- other compounds which may melt or dissolve at the temperature of the first water feed are also possible as fixing agents between the particle and the tablet.
- FIG. 2 shows a second embodiment of the composition according to the invention on the basis of a 2-layer tablet 1.
- the upper half tablet 3 consists of two parts, which both provide a sufficient cavity 5 for receiving the particle 6 and an opening to the side 11 of the tablet.
- the particle 6 is therefore not completely surrounded by the basic composition of the tablet 1, so that it is visible from the outside in the interior of the tablet 1.
- the particle in the cavity 5 can either be loosely received (provided that by appropriate selection of the size of the particle 6 on the one hand and the size of the opening of the cavity 5 to the side 11 of the tablet it is ensured that the particle or particles in the cavity do not pass through the opening can pass through) or be fixed in the interior of the cavity 5 by appropriate means, such as, for example, glue.
- a third possible embodiment results from Fig. 3.
- the basis is provided by a tablet 1 'which has a uniform structure, i.e. consists only of a layer 2 'with a uniform composition and color.
- a recess 4 ' is formed in this layer 2' by means of a suitable device.
- the particle 6' is introduced, which in this case, since the recess on the side 11 'of the tablet 1' is open to the extent that it would be possible for the particle to fall out of the recess without fixation, for example with a Adhesive 10 'or a fixing intermediate layer or mechanically (eg by friction) in the recess.
- this principle can also be applied to multilayer tablets.
- the depression can have an essentially circular cross section parallel to the side 11 '.
- any number of other cross sections is also conceivable, for example any polygon.
- the particle 6 'accommodated in the depression 4' can assume any shape (such as ellipsoid, cylinder, cuboid, etc.) (and is independent of the shape of the depression 4 '). It can also be considered to fix the particle 6 ' in a cavity open on both sides in the tablet, for example in a cylindrical hole 4 ' passing through the tablet body 1 ' , in which a corresponding cylindrical particle 6' is fixed (Fig. 4a and b).
- FIG. 5 A further possible embodiment results from Fig. 5.
- This is essentially constructed as the embodiment according to Fig. 3, i.e. a tablet 1 ', which is constructed uniformly, i.e. only from a layer 2 "with a uniform composition and color.
- the particle 6" does not only contain a core (as in FIG. 3), but rather a multiplicity of cores 8 "which are embedded in a casing 9" overall .
- fragrances can be combined with the cleaning agent for the first time, which would otherwise be incompatible with it.
- the tablet which comprises the oxidizing cleaning agent, dissolves when added to the cistern, which releases the particle according to the invention arranged on or in the tablet, its Wrapping prevents the fragrance from being released and thus vulnerable to attack by the
- such a fragrance-containing core can be produced by cooling a melt mixture of 50% melted PEG 8000, 25% fragrance and 25% diethyl phthalate in order to give, for example, a spherical particle having a weight of, for example, 0.75 g .
- benzalkonium chloride The optimal bactericidal effect of a disinfectant such as benzalkonium chloride is achieved under neutral to alkaline conditions. If benzalkonium chloride is therefore used in acidic cleaning agents (for decalcification), its performance is sub-optimal.
- an acidic cleaner tablet for metering into a toilet cistern can be combined with a particle according to the invention, the core of which contains benzalkonium chloride as a disinfectant.
- the tablet dissolves, releasing the particle according to the invention, the coating of which in the given acidic medium prevents the release of the disinfectant.
- a corresponding core for such a particle can be produced, for example, by a
- Such a core particle could, for example, consist of 1 g of a mixture of 99.7% sodium chloride and 0.3% of a corresponding indicator (e.g. methyl orange or bromocresol green).
- a corresponding indicator e.g. methyl orange or bromocresol green
- the material for the covering of the particle core (s), which comprise the substance essentially only function after the water reservoir has been at least partially emptied and inflow of fresh water unfolds, showing a solubility that depends on the concentration of a specific compound selected.
- the coating in the water feed of the water reservoir the concentration of which is determined by the dissolution of the tablet at the specific compound, is essentially insoluble and is made soluble and detaches from the particle if this concentration after at least partial emptying of the water reservoir and feed of fresh water sinks.
- concentration values of the specific compound that should be used in the screening of the polymers depend on the formulation of the base composition of the tablet into which the coated particle is to be incorporated.
- the highest concentration value used for the screening process should correspond to the concentration of the selected compound found in the first charge of the water reservoir after the base composition of the tablet has completely dissolved. Once this concentration is determined, the lower concentration should be set 10 to 100 times below this higher value.
- the materials to be examined are dissolved in solvents in which they are easily soluble.
- the solutions are distributed on glass plates and then dried at room temperature until they have a constant weight.
- the glass plates are placed in a beaker with test solution at a controlled temperature.
- the solution is then stirred with a magnetic stirrer at a controlled stirring speed. After about 10 minutes, the glass plates are removed from the beaker and dried to constant weight at room temperature. The results are expressed as weight loss [%].
- the screening methods have to be adapted to the composition of the base composition of the tablet, since this has the essential influence on the concentration of the specific compound, e.g. exercises the pH profile in the water reservoir.
- the aim in any case is to check the degree of solubility of the corresponding materials under different conditions, namely high or low concentration or pH.
- pH 8 buffer solution 500 ml stock solution
- pH 10 buffer solution 500 ml stock solution
- Screening method 1B was carried out using buffer solutions as the medium for simulating an acid medium.
- buffer solutions two buffer solutions commercially available from Merck were used, namely a citrate / HCl buffer solution with a pH of 3 and a citrate / NaOH buffer solution with a pH of 6.
- Screening procedures 2A and 2B were carried out with the following basic composition formulations to find appropriate conditions in a water reservoir, e.g. a toilet cistern to simulate.
- Screening method 3 is used to screen for compounds whose solubility changes depending on the concentration of potassium ions.
- the compounds determined using such screening methods can be used if, as described above, there is a correspondingly high concentration of potassium ions in the water reservoir, which concentration is correspondingly reduced by the inflow of fresh water.
- the screening method 3 was carried out with the following formulation in order to simulate corresponding conditions.
- the polymer was prepared in the customary manner by bulk polymerization.
- the results of screening test 1A were as follows:
- Polymer 1 films were made from a 10% solution in isopropanol.
- the invention is of course not limited to this exemplary polymer, although there is of course already a great possibility of variation with regard to the polymers mentioned in Japanese patent applications KOKAI 60-141705, 61-28440, 61-28441, 61-28596, 61 -28597 and 61-28598 or can be extended to compounds of the formula IV:
