Abstract

A method of producing a packaged composition in which a film is deformed by repeated molding into different-volume thermoforming wells is suitable for making multi-receptacle packaging.

Description

These Application relates to a packaging process. In a preferred embodiment This application relates to a process for packaging laundry detergents. or detergents.

washing or detergents are available to the consumer in a variety of forms today available. In addition to washing powders and granules, this offer includes, for example also detergent concentrates in the form of extruded or tableted Compositions. These solid, concentrated or compacted Forms of supply are characterized by a reduced volume per Dosing and thus reduce the cost of packaging and transport. In particular, the washing or cleaning agent tablets meet here additionally the desire of the consumer for simple dosage. The corresponding Agents are comprehensively described in the art. In addition to the cited However, compacted detergents or cleaning agents have advantages also a number of disadvantages. In particular, tableted offer forms draw due to their high compression often due to a delayed decay and thus a delayed Release of their ingredients. To resolve this "conflict" between sufficient tablet hardness and short disintegration times have been numerous in the patent literature technical solutions disclosed at this point by way of example to the use so-called tablet disintegrant should be referenced. This Decay accelerators add to the tablets in addition to the washing or cleaning active Substances are added, although they themselves generally do not wash or cleaning-active properties, and increase this way the complexity and the cost of these funds. Another disadvantage of tableting of active substance mixtures, in particular washing or cleaning-active substance-containing Mixtures, is the inactivation of the active substances contained by the compaction pressure occurring during tableting. Inactivation of the active substances may also be due to in Consequence of tableting enlarged contact surfaces of the Ingredients are made by chemical reaction.

When Alternative to the previously described particulate or compacted washing or detergents are becoming increasingly solid in recent years or liquid Detergents or cleaning agents containing a water-soluble or having water-dispersible packaging. Draw these funds as the tablets by a simplified dosage, since put them together with the outer packaging in the washing machine or the dishwasher can be dosed on the other hand but at the same time also the packaging liquid or powdery Detergents or cleaners, which are compared to the Kompaktaten by a better resolution and distinguish faster effectiveness.

Among the large number of commercially available phosphates, the Alkali metal phosphates with particular preference for pentasodium or pentakalium triphosphate (sodium or potassium tripolyphosphate) in the wash and Detergent industry the biggest importance.

Alkali metal phosphates is the summary term for the alkali metal (especially sodium and potassium) salts of various phosphoric acids, in which one can distinguish metaphosphoric acids (HPO ₃ ) _n and orthophosphoric H ₃ PO _{4 in} addition to higher molecular weight representatives.

The exact content of the agent on the zinc salt or zinc salts is naturally dependent on the type of zinc salts - the less soluble the zinc salt used, the higher its concentration should be in the funds.

There the insoluble Zinc salts during the Geschirreinigungsvorgangs mostly unchanged remain, is the particle size of the salts a criterion to be observed so that the salts do not affect glassware or attach machine parts. Here, agents are preferred in which the insoluble Zinc salts have a particle size below 1.7 millimeters.

If the maximum particle size of the insoluble Zinc salts below 1.7 mm are insoluble residues in the dishwasher not to be afraid. Preferably, this has insoluble Zinc salt has a mean particle size that is well below This value is in order to further minimize the risk of insoluble residues, for example a mean particle size smaller 250 μm.

Here one differentiates depending upon antimicrobial Spectrum and mechanism of action between bacteriostats and bactericides, fungistats and fungicides, etc. Important substances from these groups are, for example Benzalkonium chlorides, alkylaryl sulfonates, halophenols and phenol mercuriacetate, whereby the use of these funds can be completely dispensed with.

Plasticizers The formulations may also comprise fabric softening clay minerals which may be selected from a variety of minerals, particularly phyllosilicates. As an advantage The Smektite group has proven itself. The term smectite includes both clays in which alumina is present in a silicate lattice and clays in which magnesium oxide occurs in a silicate lattice. Typical smectites have the following general formula: Al _Z (Si ₂ O _{5) 2} (OH) ₂ · nH ₂ O and the compounds having the following formula Mg ₃ (Si ₂ O _{5) 2} (OH) ₂ · nH ₂ O. Smectites are usually in a broad three-layer structure. Specific examples of suitable smectites include those selected from the class of montmorillonites, hectorites, volkonskites, nontronites, saponites, and sauconites, especially those having alkali or alkaline earth metal ions in the crystal lattice structure. Preferred is a three-layer, expandable aluminum silicate characterized by a dioctahedral crystal lattice, whereas the extended three-layer magnesium silicate structure has a trioctahedral crystal lattice. As mentioned previously, the clay minerals contain cationic counterions such as protons, sodium ions, potassium ions, calcium ion, magnesium ions, and the like. Usually, the clay minerals are distinguished by the cations that are predominantly or exclusively absorbed. For example, a sodium bentonot is such a clay mineral in which there is predominantly sodium as the absorbed cation. Such absorbed cations can undergo exchange reactions with other cations in aqueous solutions. A typical exchange reaction involving a smectite type is as follows: Smectite (Na) + NH ₄ OH → smectite (NH ₄ ) + NaOH

In the aforementioned equilibrium reaction becomes one equivalent Ammonium ion replaced by one equivalent Sodium ion. It is usual, the cation exchange capacity in milliequivalents / 100 g (meq / 100 g). The cation exchange capacity of the clays can be determined in different ways, for example by Electrodialysis or by exchange with ammonium ions, followed by a titration, as in the book by Grimshaw, "The chemistry and physics of clays ", Pages 264 - 265, Interscience 1971, is described. Smectites such as Nontonite has an ion exchange capacity of about 70 meq / 100 g, and Montmorillonite, which has an exchange capacity of above 70 meq / 100 g have been found to be extremely preferred in the context of the present invention, since they are particularly effectively on the textiles to be treated and give them the desired Give soft grip. Particularly preferred clay minerals in the frame The present invention is therefore expanded three-layered Smectite types with an ion exchange capacity of at least 50 meq / 100 g.

organophilic Clay minerals can also be used in the context of the present invention. Such hydrophobically modified clay minerals in which inorganic Metal ions are exchanged by organic ions through the previously described exchange process are also preferred. The modified clay minerals are very good with organic solvents miscible and have the property of organic solvents between layers store. Suitable examples of organophilic clay minerals are Benton SD-1, SD-2 and SD-3 from Rheox.

Out The group of smectites has been found to be particularly preferred for the bentonites exposed. Bentonites are contaminated clays caused by weathering volcanic tuffs have arisen. Because of their high salary Bentonites have valuable properties on montmorillonite, such as Swelling capacity, Ion exchange capacity and thixotropy. It is possible the properties of bentonite according to the purpose to modify. Bentonites are as an ingredient in tropical Soils frequent and are used as sodium bentonite e.g. mined in Wyoming / USA. Sodium bentonite has the best application properties (swelling capacity), so that its Use in the context of the present invention is preferred. Naturally occurring Calcium bentonites are from, for example, Mississippi / USA or Texas / USA or from Landshut / D. The course recovered Ca bentonites become artificial exchanged by Ca for Na in the swellable Na bentonites.

The main constituents of the bentonites form so-called montmorillonites, which can also be used in their pure form in the context of the present invention. Montmorillonites belong to the phyllosilicates and here to the dioctahedral smectites belonging clay minerals, which crystallize monoclinic pseudohexagonal. Montmorillonite form predominantly white, grayish-white to yellowish, completely amorphous appearing, easily friable, in the water swelling, but not plasticizing masses, by the general formulas Al ₂ [(OH) ₂ / Si ₄ O ₁₀ ] .nH ₂ O or Al ₂ O ₃ · 4SiO ₂ · H ₂ O · nH ₂ O or Al ₂ [(OH) ₂ / Si ₄ O ₁₀ ] (dried at 150 °) can be described.

Montmorillonites have a three-layer structure consisting of two tetrahedral layers, which are electrostatically crosslinked via the cations of an octahedral intermediate layer. The layers are not rigidly connected, but can swell by reversible incorporation of water (in 2-7 times the amount) and other substances such as alcohols, glycols, pyridine, ammonium compounds, hydroxy-aluminosilicate ions, etc. The above. Formulas are only approximate formulas since montmorillonites have a high ion exchange capacity. Thus Al can be exchanged for Mg, Fe ²⁺ , Fe ³⁺ , Zn, Cr, Cu and other ions. As a result of such substitution, a negative charge of the layers results, which is balanced by other cations, especially Na ⁺ and Ca ²⁺ .

Calcium or magnesium bentonites are usually non-swellable and usually less effective plasticizers. However, it is advantageous to combine non-swellable bentonites with carrier materials, such as polyethylene glycol, to achieve a significantly improved softness of the textiles treated therewith. Also advantageous are calcium or magnesium bentonites, which are used in the presence of a sodium source, such as NaOH or NaCO ₃ .

A detailed description of the process for the treatment of bentonite is found in WO 00/03959, the disclosure of which in this application full is incorporated.

The crystalline structure of montmorillonite is more or less resistant to Acid treatment. Under acid treatment In the context of the invention, it is understood that a sample of the clay (for example, 1 g / L) in a 1N HCl solution for 15 Hours at a temperature of 80 ° C is exposed. It must be mentioned that the Most clays by acid treatment can be destroyed with, for example Flourwasserstoff. In the context of the present Invention is under acid treatment however, the HCl treatment meant. Montmorillonite (magnesium saturated / air dried) show for usually a maximum diffraction distance of 14-15 Å in the 001 plane when with X-rays be treated. This maximum diffraction distance changes usually too not by the fact that Clay is treated with HCl.

In the context of the present invention, however, acid-sensitive montmorillonites are preferred, ie For example, montmorillonites whose crystalline structure is destroyed when treated with HCl. The use of such clay minerals has a softness-improving effect and also provides for better dispersibility in the aqueous wash liquor or the aqueous fabric treatment liquor. Destruction of the crystalline structure can be determined by measuring the diffraction distance so that, for the destroyed montmorillonites, the maximum diffraction distance expected for crystalline montmorilonites does not appear in the 001 plane of 14-15 Å.

Without being bound by theory, it is believed that the acid sensitivity is related to increased exchange of aluminum by magnesium in the octahedral layer of the montmorillonite clay. Preferred is a ratio of Al ₂ O ₂ / MgO of less than 4, more preferably of less than 3. The aforementioned acid-sensitive montmorillonites have the advantage that they allow a reduced tendency to gel as well as an improved dispersibility in the wash liquor. In addition, it has been observed that such clay minerals produce improved softness.
