Definitions
- the invention relates to a method for producing a tablet, in particular a detergent tablet, with at least a first and a second layer, and a product that can be produced thereafter.
- two-layer tablets are increasingly to be found, in which there is a different distribution of ingredients in the two layers, on the one hand to separate incompatible ingredients from one another until the tablet is used, and on the other to realize different release profiles of ingredients.
- a first mixture with a first composition is usually first filled into a mold and pre-pressed with a first pressure.
- a second mixture with a second, different composition is then filled onto the pre-pressed first layer in the mold and the final pressing is carried out at a second, usually higher pressure.
- the causes of the layers separating from one another can be varied. eg different before volume expansion of the individual layers. Reactions at the interface between the layers, etc. It is therefore essential to precisely match the compositions of the individual layers and to precisely adjust the pressures when pressing the individual layers.
- the development and manufacture of stable multi-layer tablets is therefore time-consuming and costly, and is sensitive to changes in internal and external parameters in the process.
- the invention is therefore based on the object of developing the known method in such a way that the production of more stable multilayer tablets-i is made possible, in which the individual layers are separated from one another to a much lesser extent.
- the invention relates to a method for producing a tablet, in particular a detergent tablet, with at least a first and a second layer, comprising the following steps a) introducing a first measured amount of a first particulate composition into a mold depression of a tablet press; b) pressing the first measured quantity with a first pressing pressure by means of a pressing die which has at least one protrusion on its pressing surface in order to produce a first pressed layer which in its upper surface has a depression corresponding to the protrusion (s) on the pressing die (en) has; c) placing a second measured amount of a second particulate composition on the first pressed layer in the mold cavity of the tablet press; and d) pressing the second measured quantity with a second pressing pressure by means of the pressing die to produce a second pressed layer with a corresponding recess (s) in its upper surface, and product which can be produced thereafter.
- steps (c) and (d) are repeated for the production of a third and possibly further layers.
- the depression (s) formed in the uppermost layer of the tablet in the process according to the invention is (are) preferably filled.
- the shaped body (s) is (are) preferably fixed in the recess (s) with a substance which provides a transport-safe connection between the tablet and the shaped body, in a particularly preferred embodiment with an adhesive.
- the invention further relates to a multilayer tablet, in particular a cleaning tablet, which can be produced using the method according to the invention.
- the single figure shows an embodiment of the invention in cross section as a two-layer tablet with a molded body fixed in the depression in the top layer.
- the lower layer 10 of the tablet 1 is first produced by placing a first measured amount of a first particulate composition in a mold depression of a tablet press and pressing it there with a first pressing pressure by means of a pressing die which has a bulge on its pressing surface , which is essentially complementary to the depression 12 thus created in the upper surface 11 of the lower layer 10 of the tablet 1.
- a second measured amount of a second particulate composition (which is usually different from the first particulate composition) is placed on the first pressed layer 10 in the mold cavity of the tablet press and with a second compression pressure (which is usually higher than the first compression pressure) the second layer of the tablet 20 is pressed by means of the press ram.
- the two tablet layers 10 and 20 are not only pressed against one another along the horizontal boundary layer, but in particular also in the depression 12 of the lower layer 10, which also results in laterally directed pressing forces, that is to say the second composition is particularly strong and firm in the depression 12 of the lower layer Layer 10 is pressed in.
- the depressions 24 formed on the upper side 23 of the upper layer 20 by the production method according to the invention can be left as they are or preferably be filled with a further material which can also take on further functions when the tablets are used.
- a molded body 30 is fixed in a suitable manner in the recess 24 (at least in its lower part), for example by an adhesive.
- the molded body 30 of the illustrated embodiment has a core 31 and an additional protective sheath 32 in order to protect it, for example, during storage and to control the release of the contents of the core 31 when in use.
- compositions of the tablet or shaped body can vary widely depending on the use. Various options in the preferred area of application are shown in the following examples.
- compositions of the tablets in Examples 1 to 7 represent dishwashing detergent compositions, with the tablets of Examples 2 to 7 the depressions in the top of the top layer being filled with various shaped articles.
- Example 8 describes a detergent tablet and a detergent tablet.
- the following table relates to the composition of the two layers of a two-layer dishwasher tablet (weight ratio approx. 50:50).
- layer 1 is the first (lower) layer that is only slightly compressed in step (b) (oh- ne actual compression), which is sufficient. to form a smooth surface with the corresponding recess in the top.
- step (b) oh- ne actual compression
- Nonionic surfactant 5 Nonionic surfactant 2
- Binder dye. Water ad water 100 ad 100
- Examples 2 to 7 also relate to two-layer dishwasher tablets, the composition of individual layers of the tablet being changed only slightly (if at all) compared to that of Example 1.
- Example 1 specific examples of use of various molded articles are described for illustration purposes, which can be inserted into the depression formed in the method according to the invention in the upper side of the top (second) layer and can be fixed, for example, with adhesive.
- the actual manufacturing process of the tablet, in particular the compression pressures described in Example 1 remain unchanged.
- the protease then contained is released faster than the one contained in the tablet and can therefore have its effect right at the beginning of the main rinse cycle.
- fresh enzymes protease and amylase
- composition of the tablet essentially corresponds to that of Examples 1 and 2, with the difference that hot water-stable protease or amylase is used in layer 2 of the tablet.
- composition of the molded body corresponds to that of the molded body of Example 2.
- the different activity profiles of the different protease and amylase types can unfold optimally.
- the molded body sets cold water-active protease and amylase at the beginning of the main wash cycle free.
- This embodiment enables a time-delayed dissolution of lipase and protease which are incompatible in solution.
- This embodiment enables a time-delayed dissolution of enzymes which are incompatible in solution with bleaching agents.
- the peracid released can work under the necessary acidic conditions.
- the usual optimal alkaline rinsing condition for protease and amylase is achieved.
- the following table shows an exemplary formulation for a two-layer washing intensifier tablet.
- the weight of the first (lower) layer is approximately 74% of the total tablet, while the second (upper) layer is approximately 26%.
- the following table shows an exemplary formulation for a detergent tablet, in which case the two layers are in a weight ratio of 70 (lower (1st) layer) to 30 (upper (2nd) layer).
- the release of an acid in the rinse cycles of a washing machine is intended both to remove incrustations and to neutralize alkaline residues.
- weak acids are used for this purpose, such as amidosulfonic acid and / or maleic acid. These materials are usually solids
- the manufacturing process is as follows:
- a mixture of 1.05 g of amidosulfonic acid and 0.45 g of maleic acid are formed in a rotary press under a pressure of 890 kg / cm to a shaped body.
- Example 7a Taking into account similar considerations as in Example 7a, a corresponding molded body is produced as follows:
- 0.1975 g of fragrance is absorbed onto 0.0525 g of finely divided silica to give a free-flowing granular material.
- the resulting 0.25 g is mixed with 0.6 g of microcrystalline cellulose and 0.15 g of cross-linked polyvinylpyrrolidone.
- the mixture is tableted in a round press with an inner diameter of 10 mm under a pressure of 2900 kg / cm to give an elliptical shaped body with a height of 13.1 mm and a weight of approx. 1 g.
- such molded bodies can be produced as follows: 1 g of chlorine bleach, e.g. pure sodium dichloroisocyanurate. can be pressed into a molded body in a suitable press under a pressure of 5,600 kg / cnT.
- the molded body comprises several substances which are intended to develop their respective effects in the washing cycle of a washing machine.
- it is a combination of a fabric softener, an agent for reducing the build-up of static electricity in the fabric and an agent for improving the re-absorption of moisture by the fabric.
- a slurry of 58% urea, 18% dimethyldistearylammonium chloride (DMDSAC) (90%), 8% of a C 9 n alcohol ethoxylated with 9 moles of ethylene oxide and 16% water was prepared.
- the slurry was spray dried to obtain a granular material with a density of 580 g / l and the following composition: 68.8% by weight urea, 19.2% by weight DMDSAC, 9.5% by weight non-ionic Surfactant and 2.5% by weight water.
