    The present invention relates to the cosmetics sector and relates to a product for the oxidation modification of the color of keratinous fibers and in particular human hair, which comprises a preparation of aqueous hydrogen peroxide packaged in a sachet. The hydrogen peroxide preparation is distinguished by the content of defined stabilizers. The pouch used as a packaging for the hydrogen peroxide preparation is a special bag based on multilayer composite film whose walls contain at least two polymer layers and a barrier layer. The barrier layer has a barrier effect against gases and water vapor.
    The modification of the color of keratinous fibers and in particular human hair constitutes an important area of modern cosmetics. It makes it possible to adapt the appearance of the hair as well to the trends of the current fashion as to the wishes of the individuals. Each specialist has different possibilities to change the color of the hair.
    By using direct acting dyes, it is possible to obtain a temporary change in the color of the hair. Their operating principle is the diffusion of ready-to-use dyes from the dye product into the hair fiber. Staining with direct-acting dyes is less damaging to hair, but dyes obtained from direct-acting dyes have the disadvantage of being unsustainable and fade after a few washes.
    For this reason, or when the consumer wants the color to persist in the long term or wants a lighter tone than its natural color, oxidation color modifiers are usually used. For permanent dyes which are intense and therefore resistant to washing, oxidation dyes are used. These coloring agents usually contain oxidation dye precursors, called developer components and component-copulators, the combination of which forms the clean dye under the influence of oxidizing agents - usually hydrogen peroxide. Oxidation stains are distinguished by excellent and long-lasting staining results. The lightening of the tone or the discoloration of the hair alone is frequently done using oxidizing agents without the addition of oxidation dye precursors. For a moderate discoloration effect, it is sufficient to use only hydrogen peroxide; to obtain a more intense discoloration effect, a mixture of hydrogen peroxide and peroxide pyrosulfate salts is usually used.
    The oxidation color modifiers are usually sold as two-component agents where two different preparations occur in two separate packages which must be mixed shortly before use.
    The first preparation is a formula - usually rendered acidic for stability reasons - which contains hydrogen peroxide in concentrations of between 1.5 and 12% by weight as an oxidizing agent. The formula of the oxidizing agent is most often in the form of an emulsion or dispersion and is generally sold with a resealable dispensing opening in a plastic bottle (developer bottle).
    Before application, this hydrogen peroxide formula is mixed with a second preparation. This second preparation is an alkaline formula presented most often in the form of cream or gel and which, in addition, contains oxidation dye precursors when it is desired to obtain a color change at the same time as the discoloration. This second preparation can be sold, for example, in a tube or in a plastic or glass container.
    In the usual form of application described above, the second preparation, which contains the basifying agent and / or the oxidation dye precursors, is poured from the tube or container into the developer bottle and then mixed by shaking with the preparation of hydrogen peroxide in the developer bottle. In this way, the dye mixture is prepared in the developer bottle. The application on the hair is done with a small spout or a dosing opening on the head of the revealing bottle. After mixing the preparation by shaking, the consumer opens the spout or the dosing opening and removes the dye mixture by pressing the flexible developer bottle. The use of the developer bottle requires the consumer a certain routine and, therefore, many people prefer to prepare the mixture in a mixing bowl or apply it using a brush.
    By preparing the dyeing mixture in a bowl, the two components - the first preparation, containing the hydrogen peroxide, and the second mixture, containing the alkalizing agent and / or the oxidation dye precursors - are integrally poured into the bowl or in a similar container where they are mixed with a brush. The removal of the paint mixture is then done mixing bowl and using the brush. This form of application does not require a bulky, expensive and expensive developer bottle, and research into low-cost, material-saving packaging for the preparation of hydrogen peroxide is still underway.
    In this context, the bag is a form of low-cost packaging whose manufacture requires a reduced amount of material. A sachet is a pouch or bag package frequently used in the packaging of cosmetics. As a rule, the bags are based on plastic films or metal films.
    A typical bag can be made, for example, by gluing or hot pressing of two plastic films superimposed, the bonding comprising all the edges of the films. Then it is possible to fill the inside of the bag obtained by gluing (that is to say the plastic bag) with the desired cosmetic preparation. The opening of the bag can be done by tearing or cutting the plastic bag.
    The filling of sachets with hydrogen peroxide preparations, however, presents problems due to the reactivity of the peroyde. Hydrogen peroxide is a highly reactive substance that decomposes to a small extent by forming oxygen (ie gas) depending on the conditions of storage and, where appropriate, the presence of contaminations that promote its decomposition.
    The prior art known developer bottles generally lend themselves to a maximum filling up to half their internal volume and usually they are filled with hydrogen peroxide only up to one-third . As a rule, the revealing bottles are made of polyethylene. Since polyethylene is permeable to both water vapor and gas, no or very little overpressure develops in the developer bottle. In addition, the developer bottles usually have stable and thick walls and a stable screwed closure, which reduces the diffusion of water vapor or even gases and ensures that the negligible increase in pressure which takes place inside the bottle has little effect on the result.
    On the contrary, the sachets are completely filled with the liquid preparation and the filled sachet contains almost no excess air. In addition, the bag must remain flexible and it must be avoided that, when opened (eg by tearing or cutting), the preparation will come out uncontrollably. For this reason, when packaging liquid preparations, it is recommended to avoid, as far as possible, the generation of excess pressure in the bag.
    When a hydrogen peroxide preparation is contained in the sachet, the gas (oxygen) that forms during storage can cause the sachet to swell. Since, usually, the edges of the bag are only glued, a large swelling can, at worst, cause the bursting of the bag. For these reasons, the choice of the material of the films making up the pouch is of the utmost importance in the context of the packaging of preparations which contain hydrogen peroxide.
    Bags made of pure plastic such as polyethylene or polypropylene are permeable to both water vapor and gases. This means that when packaging preparation containing hydrogen peroxide, the polyethylene or polypropylene bags do not swell. However, because of the high water vapor permeability of the comparatively thin film of the sachet, the water content of the preparation decreases. When the preparation is kept in the sachet for several weeks up to a few months, the water loss exceeds any acceptable limit. Pellets made of plastic film laminated with a layer of metal, for example an aluminum layer, are also manufactured which are completely impermeable to air. These bags are also completely impermeable to water vapor and gases. When these bags are filled with a preparation containing hydrogen peroxide, the gas formed at the decomposition of the peroxide can not escape, the bag inflates as described above and bursts. The purpose of this patent application is to package the hydrogen peroxide preparation in a bag saving material and space, safe and above all stable storage.
    Surprisingly, it has been found possible to pack the hydrogen peroxide formulations into pouches in a stably stable manner by using for the purpose of packaging sachets composed of special composite film systems and having a layer of barrier and provided that hydrogen peroxide preparations in sachets contain special stabilizers. The object of the present invention is a cosmetic product for the oxidation modification of the color of keratinous fibers and in particular human hair comprising - a preparation (A) packaged in a sachet (S) in which - the preparation (A) contains (A1) water and (A2) hydrogen peroxide and (A3) at least one 2,6-dipicolinic acid group stabilizer, 1-hydroxyethane-1,1-diphosphonic acid (HEDP), benzoic acid salicylic acid, ethylene-diamine tetraacetic acid (EDTA), ethylene diamine tetramethylene phosphonic acid (EDTMP), diethylene triamine pentamethylene phosphonic acid (DTPMP), amino trimethyl phosphonic acid (ATMP), N, N-bis {2- [bis (carboxymethyl) amino] ethyl} glycine, ethylene-diamine-N, N-disuccinic acid (EDDS), 2-hydroxypropylene-diamine-N, N'-disuccinic acid (HPDDS) ethylenediamine-N, N'-diglutaric acid (EDDG), ethylene-diamine-N, N'-bis- (ortho-hydroxy-phenyl) acid l) acetic acid (EDDHA), diphosphoric acid, hydrated stannic oxide and / or physiologically tolerable salts of these substances, and - a bag wall (S) composed (51) of a first layer based on a first polymer material and (52) a second layer based on a second polymeric material and (SBa) a barrier layer against gas and water vapor.
    The term keratinous fibers includes furs, wool and feathers, but especially human hair. Even if the agents within the meaning of the invention are intended essentially for the lightening and coloring of keratinous fibers, in principle there is no reason that would speak against its use in other fields.
    The product within the meaning of the invention is a product for the oxidation modification of keratin fibers and in particular human hair, that is to say a product applied to the human head to obtain an oxidation coloring, a lightening of the tone, discoloration, bleaching, or change in the tone of hair. In this context, the change in tone designates a coloration whose result is a hue lighter than the natural color of the hair.
    The product within the meaning of the invention comprises a preparation (A) packaged in a sachet (S) and distinguished by its water content (A1) and hydrogen peroxide (A2) and one or more stabilizers of the group (A3). The use of the product within the meaning of the invention is the modification of the color by oxidation. As described above, a preparation (A) which contains hydrogen peroxide and a second preparation (B), packaged separately from the preparation (A), is usually mixed. In this way, the ready-to-use oxidation color modifier is obtained. Depending on the effect desired by means of the oxidation color change -decoloration, lightening or coloring -, the preparation (B) may contain various components. For lightening or even discoloration only, the preparation (B) contains at least one basifying agent. If it is desired to obtain an oxidation coloring, the preparation (B) contains, in addition to the basifying agent, frequently oxidation dye precursors. In order to ensure the properties required for the sufficiently rapid mixing of the preparations (A) and (B), both the preparation (A) and the preparation (B) are usually fluid, aqueous or hydrated preparations.
    For the purposes of the invention, the preparation (A) is an aqueous preparation. The water content of the preparation (A) relative to the total weight of the preparation (A) may be, for example, between 60.0 and 97.0% by weight, preferably between 75.0 and 93% by weight. weight and in particular between 78.0 and 91% by weight and, most preferably, between 80.0 and 88.0% by weight. All indications in percent by weight refer to the proportion by weight of the water (A1) contained in the preparation (A) relative to the total weight of the preparation (A).
    A particularly preferred embodiment of the product within the meaning of the invention is distinguished by the fact that the preparation (A) - always with respect to the total weight of the preparation (A) - contains water (A1) in a proportion between 60.0 and 97.0% by weight, preferably between 75.0 and 93% by weight and in particular between 78.0 and 91% by weight, the particularly preferred water content being between 80.0 and 88, 0% by weight.
    In addition, the preparation (A) contains, as a second essential characteristic of the invention (A2), hydrogen peroxide. The concentration of the hydrogen peroxide contained in the preparation (A) is governed on the one hand by the legal requirements and on the other hand by the desired effect: preferably aqueous solutions are used. at a hydrogen peroxide content of between 0.5% and 20% by weight. Preferred preparations (A) within the meaning of the invention are distinguished by the fact that, based on the total weight of the preparation (A), they contain a proportion of hydrogen peroxide (A2) of between 0.5 and 20 , 0% by weight, preferably between 1.5 and 17.0% by weight and in particular between 1.5 and 15.0% by weight and, most preferably, between 1.5 and 12.0% by weight.
    The higher the proportion of hydrogen peroxide (A2) of the preparation (A), the greater the amount of gas resulting from the decomposition of the hydrogen peroxide. Therefore, it is much more difficult to pack in a storage-stable bag with higher hydrogen peroxide preparations than less concentrated preparations.
    In the context of the work leading to the present invention, it has been found that the product within the meaning of the invention is also particularly suitable for the packaging and the stable preservation of preparations (A) containing higher concentrations of 'hydrogen. Thus, even after storage at high temperature for several weeks, the sachets within the meaning of the invention (S) containing preparations (A) with a content of hydrogen peroxide of between 9 and 12% by weight, have no changes in volume (i.e., no swelling) or accidental openings (i.e., the sachets did not burst).
    For this reason, the particularly preferred cosmetic products are those in which the preparation (A) packaged in the sachet (S) contains a quantity of hydrogen peroxide of between 1.5 and 12.0% by weight, preferably between 3 and 12% by weight. , 0 and 12.0% by weight and in particular between 6.0 and 12.0% by weight, the particularly preferred content of hydrogen peroxide being between 9.0 and 12.0% by weight. All indications in percent by weight refer to the weight ratio of hydrogen peroxide (A2) contained in the preparation (A) relative to the total weight of the preparation (A).
    Another particularly preferred embodiment of the product according to the invention is distinguished by the fact that the preparation (A) - always with respect to the total weight of the preparation (A) - contains hydrogen peroxide (A2) in a proportion of between 1.5 and 12.0% by weight, preferably between 3.0 and 12% by weight and in particular between 6.0 and 12.0% by weight and, particularly preferably, between 9.0 and and 12.0% by weight.
    As a third essential component within the meaning of the invention, the preparation (A) contains one or more stabilizers (A3) chosen from the 2,6-dipicolinic acid, 1-hydroxyethane-1,1-diphosphonic acid (HEDP) group. benzoic acid, salicylic acid, ethylene diamine tetraacetic acid (EDTA), ethylene diamine tetramethylene phosphonic acid (EDTMP), diethylene triamine pentamethylene phosphonic acid (DTPMP), amino trimethyl phosphonic acid (ATMP) N, N-bis {2- [bis (carboxymethyl) amino] ethyl} glycine, ethylene-diamine-N, N'-disuccinic acid (EDDS), 2-hydroxypropylene-diamine-Ν, Ν'-disuccinic acid (HPDDS) ), ethylene-diamine-N, N'-diglutaric acid (EDDG), ethylene-diamine-N, N'-bis- (ortho-hydroxy-phenyl) acetic acid (EDDHA), diphosphoric acid, hydrated stannic oxide and / or physiologically tolerable salts of these compounds.
    Stabilizers within the meaning of the present invention are substances capable of forming chelates or complexes, which fulfill a function of free radical scavengers and / or which can form insoluble metal salts.

    Within the meaning of the invention, the preparation (A) is packaged in a bag (S) whose wall is constituted (51) of a first layer based on a first polymer material and (52) a second layer based on a second polymer material and (SBa) a barrier layer with a barrier effect against gases and water vapor.
    In other words, the preparation (A) is packaged in a sachet (S), this sachet (S) consisting of a multilayer composite system provided (51) with a first layer based on a first polymer material and (52) ) a second layer based on a second polymer material and (SBa) a barrier layer barrier against gases and water vapor.
    A sachet (S) within the meaning of the present invention is a small package in the form of a bag or bag. The capacity of the sachet may be, for example, between 5 and 1000 ml, preferably between 10 and 200 ml and particularly preferred between 20 and 50 ml.
    Preferably, the bag (S) consists of a multilayer composite system, that is, the bag is made using a composite film that has multiple layers. This multilayer film constitutes the wall or even the outer envelope of the bag. As described above, the bag is usually obtained by gluing, pressing or welding two superposed film elements (filling the bag simultaneously with the preparation (A)), ie all the edges of the sachet are closed again. . To open the bag, it can, for example, tear or cut.
    The composite film used preferably for the manufacture of the bag consists of at least three layers and in particular (51) a first layer based on a first polymer material and (52) a second layer based on a second polymeric material and (SBa) a barrier layer with a barrier effect against gases and water vapor.
    It is advisable to choose the thickness of the composite film so that it has sufficient mechanical stability but that the film - and, consequently, the bag made from the film - remains flexible enough to allow the removal of the film. the entire preparation (A) of the bag (S) opened by tightening or pressing the film bag once it is open. These claims are fulfilled in particular when the multilayer composite system consists of a multi-layer film having a total thickness of between 21 μm (micrometers) and 2.0 mm (millimeters), preferably between 30 μm (microns) and 1 μm. , 0 mm (millimeters), in particular between 50 μm (micrometers) and 500 μm (micrometers) and, most preferably, between 60 μm (micrometers) and 200 μm (micrometers).
    Therefore, a product to be favored explicitly and particularly for the purposes of the invention is distinguished by the fact that the bag wall consists of a multilayer film and a total thickness between 21 microns (microns) and 2 microns. , 0 mm (millimeters), preferably between 30 pm and 1.0 mm, in particular between 50 pm and 500 pm and, most preferably, between 60 pm (micrometers) and 200 pm (micrometers).
    For the purposes of the present invention, the terms multilayer composite system and multilayer composite film are used as synonyms. For the purposes of the invention, the term total thickness of the bag refers to the total thickness of all the individual layers of which the film is composed.
    The multilayer composite system (i.e. the multilayer composite film) comprises at least three layers, (51) a first layer based on a first polymeric material and (52) a second layer based on a second polymer material and (SBa) a barrier layer with a barrier effect against gases and water vapor.
    The layers can also be called strata. All layers are parallel to the surfaces of the composite film.
    The first polymer material of the first layer (S1) within the meaning of the invention is an organic polymeric material. The second polymer material of the second layer (S2) within the meaning of the invention is also an organic polymeric material.
    The arrangement of the layers (S1), (S2) and (SBa) may vary; likewise, the wall of the bag may comprise, in addition to the three layers (S1), (S2) and (SBa) still one or more additional layers.
    When the multilayer composite system (i.e. the multilayer composite film) comprises at least three layers, it is possible to arrange them, for example, as follows:
    An arrangement within the meaning of the invention is as follows (from inside to outside): * inside * - layer (S1) - layer (S2) - barrier layer (SBa) - * outside * In this case , the multilayer film consists of three layers, the layer (S1) located inside being in contact with the preparation (A). The layers (S1) and the layer (S2) are similar. In order to make it possible to differentiate between these two layers, the polymeric materials constituting the two layers (S1) and (S2) are different. The barrier layer (SBa) is outwards. In films having this arrangement of the layers, the layer (S1) may, for example, fulfill a function of a polymeric support layer to which the second polymer layer (S2) is applied. Then, the side adjacent to the layer (S2), that is to say the outer side, is provided with the barrier layer. Together, the three layers (S1), (S2) and (SBa) form a multilayer film whose total thickness is preferably between 30 pm and 1.0 mm.
    Another provision within the meaning of the invention is the following (from inside to outside): 'inside * - barrier layer (SBa) - layer (S1) - layer (S2) - outer side * In this In this case, the multilayer film consists of three layers, the barrier layer (SBa) located inside being in contact with the preparation (A). The layers (S1) and the layer (S2) are similar. In order to make it possible to differentiate between these two layers, the polymeric materials constituting the two layers (S1) and (S2) are different. The layer (S2) is outwards. Together, the three layers (SBa), (S1) and (S2) form a multilayer film whose total thickness is preferably between 30 pm and 1.0 mm.
    The preferred layer arrangement is where the barrier layer (SBa) is located between the two polymer layers (S1) and (S2). In this arrangement too, the multilayer composite system may comprise, in addition to the three layers (S1), (S2) and (SBa), also one or more additional layers.
    Another product to be particularly preferred in the sense of the invention is further distinguished by the fact that the barrier layer (SBa) is located between the two polymer layers (S1) and (S2).
    The arrangement of this embodiment to be particularly preferred is the following (from the inside to the outside): 'inside * - layer (S1) - barrier layer (SBa) - layer (S2) -'side outside * In this In this case, the multilayer film consists of three layers, the inner layer (S1) being in contact with the preparation (A). The layer (S1) is in contact with the barrier layer (SBa), this barrier layer (SBa), it is in contact with the layer (S2). In this arrangement, the layers (S1) and (S2) are not close but they are separated by the barrier layer (SBa). In this arrangement, it is possible, in principle, for the layers (S1) and (S2) to be of the same polymeric material, but it is preferable that the two layers (S1) and (S2) consist of different polymer materials. Together, the three layers (S1), (SBa) and (S2) form a multilayer film whose total thickness is preferably between 30 pm and 1.0 mm. The particular advantage of this arrangement is that the barrier layer (SBa) - often very thin - is neither on the inner surface nor on the outer surface of the multilayer film but is protected on the inside by the polymer layer (S1) and on the outside by the polymer layer (S2). In this way, it is possible to best prevent the abrasion or mechanical destruction of the barrier layer (SBa).
    The wall of the bag (S) within the meaning of the invention comprises a first layer (S1) consisting of a first polymer material. The first polymeric material may be a layer of a type of polymer or a layer of a polymer blend. For example, this first layer (S1) can fulfill the function of polymeric support material, that is to say, during the production of the film, it is possible to first lay a layer or a film (S1) of polymer material on which other layers are applied in the sense of the invention by vaporization, rolling or coating. Preferably, the first layer (S1) is made of polypropylene, polyethylene, polyester, polyamide or polyvinyl alcohol. In a particularly preferred embodiment, the layer (S1) is made of polypropylene.

    A particularly preferred product for the purposes of the invention is distinguished by the fact that the wall of the bag (S) comprises (S1) a first polypropylene layer.
    Polypropylene, also known as poly-1-methylethylene, is a thermoplastic polymer which belongs to the group of polyolefins. Polypropylene is obtained by polymerization of propene (propylene) using different catalysts. For example, it is possible to obtain polypropylene by stereospecific polymerization of propylene in the gas phase or in suspension according to the Ziegler-Natta process. The polypropylenes to be used in the sense of the invention may be isotactic and therefore highly crystalline or syndiotactic or amorphous. The regulation of a relative average molar mass can be done, for example, by using a partial pressure of hydrogen during the polymerization of propene. For example, the polypropylene may have average relative molar masses of between approx. 150,000-1,500,000 g / mol. The polypropylene can be processed by extrusion blow molding, stretch blow molding or pressing, calendering, thermoforming or cold forming. The thickness of the first layer (S1) may be, for example, in a range of 20.0 to 300.0 μm (microns) and the preferred layer thickness is between 40.0 and 200.0 μm. (micrometers), especially between 50.0 and 100.0 μm (micrometers) and, most preferably, between 60.0 and 90.0 μm (micrometers).
    A particularly preferred product for the purposes of the invention is distinguished by the fact that the wall of the bag (S) comprises (S1) a first layer of a first polymeric material and whose thickness is between 20.0 and 300 0 μm (micrometers), preferably between 40.0 and 200.00 μm, in particular between 50.0 and 100.0 μm, and particularly preferably between 60.0 and 90.0 μm (micrometers).
    A product for the purposes of the invention to be explicitly and particularly preferred is distinguished by the fact that the wall of the bag (S) comprises (51) a first polypropylene layer whose thickness is between 20.0 and 300.0 μm ( micrometers), preferably between 40.0 and 200.00 μm, in particular between 50.0 and 100.0 μm, and most preferably between 60.0 and 90.0 μm (micrometers).
    In addition, the multilayer film of which the bag is constituted comprises a second layer (S2) based on polymeric material. The second polymeric material may be a layer of a type of polymer or a layer of a blend of polymers. During the manufacture of the multilayer film, it is possible, for example, to apply the second layer (S2) to the support layer (S1) by vaporization, rolling or coating before or after the application of the layer. -barrier (SBa). It is also conceivable for the second layer (S2) to fulfill the function of a support layer on which the barrier layer (SBa) and the first polymer layer (S1) are applied.
    Depending on the arrangement of the layers as described above, the first polymer material of the first layer (S1) and the second polymer material of the second layer (S2) may be the same (if the two layers are not in contact from each other) or they may be different materials. Preferably, the (S1) and (S2) layers are of different polymeric materials (ie, different polymers or polymer blends). The second layer (52) may be polypropylene, polyethylene, polyester and / or polyamide. In a particularly preferred embodiment, the second layer (S2) consists of polyethylene terephthalate.
    A particularly preferred product of the invention is distinguished by the fact that the wall of the bag (S) comprises (S2) a second layer of polyethylene terephthalate.
    Polyethylene terephthalate (PET) is a polymer from the group of polyesters. Polyethylene terephthalate (PET) is obtained, for example, by means of transesterification of dimethyl terephthalate with ethylene glycol at elevated temperatures. In the transesterification reaction, methanol is dissociated and then distilled off. The bis (2-hydroxyethyl) terephthalate which results from this reaction is converted into PET by polycondensation, a process in which ethylene glycol is formed again. Another method of producing polyethylene terephthalate is the direct polycondensation of ethylene glycol and terephthalic acid at elevated temperatures by distilling off the water that forms in this process. The thickness of the first layer (S2) may be, for example, in a range of 1.0 to 100.0 μm (micrometers) and the preferred layer thickness is between 2.5 and 50.0 μm. in particular between 5.0 and 25.0 .mu.m and particularly preferably between 10.0 and 20.0 .mu.m (micrometers).
    A particularly preferred product for the purposes of the invention is distinguished by the fact that the wall of the bag (S) comprises (S2) a second layer of a second polymeric material and whose thickness is between 1.0 and 100 , 0 μm (micrometers), preferably between 2.5 and 50.00 μm (micrometers), in particular between 5.0 and 25.0 μm (micrometers) and, most preferably, between 10.0 and 20, 0 pm (micrometers).
    A product for the purposes of the invention to be explicitly and particularly preferred is distinguished by the fact that the wall of the bag (S) comprises (S2) a second layer of polyethylene terephthalate and whose thickness is between 1.0 and 100 , 0 μm (micrometers), preferably between 2.5 and 50.00 μm (micrometers), in particular between 5.0 and 25.0 μm (micrometers) and, particularly preferred, between 10.0 and 20.0 μm (micrometers) .
    As the essential third layer for the invention, the multilayer composite system (i.e., the multilayer composite film) of the bag (S) comprises a barrier layer (SBa) impervious to gas and steam. water.
    The layers (S1) and (S2) of the composite film consist of organic polymeric materials. As a general rule, organic polymers do not have a sufficient barrier effect against gases and water vapor. When the aqueous preparation (A) is packaged in a bag made of a multilayer film which comprises only the two organic polymeric layers, the water vapor can escape freely, resulting in an unacceptable change in the water content of the water. the composition in case of prolonged storage.
    In order to minimize the uncontrolled escape of the water vapor from the bag in a targeted manner, the polymer layers (S1) and (S2) are employed in a composite system comprising a barrier layer (SBa).
    The barrier layer (SBa) has a barrier effect against gases and water vapor. For the purposes of the invention, this means that the barrier layer (SBa) reduces the rate of permeation through the film for water vapor and gases.
    A film within the meaning of the invention which is provided, in addition to the layers (S1) and (S2), with a barrier layer (SBa) has a reduced permeability to water vapor and gases compared to a comparable film (to the same total thickness) but which consists only of the two layers (S1) and (S2) and which has no barrier layer (SBa).
    The barrier layer (SBa) is, for example, a thin layer which comprises an inorganic material, which inorganic material can be applied using vacuum coating techniques (eg PVD ("physical vapor deposition") or CVD ("Chemical vapor deposition") on organic polymer layers (S1) and / or (S2).
    If the barrier layer (SBa) is a layer which comprises at least one inorganic material, it is possible to use, for example, aluminum, aluminas, magnesium, magnesium oxides, silicon, oxides of silicon, titanium, titanium oxides, tin, stannic oxides, zircon, zircon oxides and / or carbon.
    The manufacture of films comprising a barrier layer based on inorganic material is described, for example, in EP 1036813 A1 to which we make full reference herein.
    In this context, the use of oxides selected from the group of aluminas, magnesium oxides, silicon oxides, titanium oxides, stannic oxides and / or zircon oxides is particularly preferred. In a particularly preferred embodiment, the barrier layer (SBa) of inorganic material is between the two polymer layers (S1) and (S2).
    A particularly preferred product for the purposes of the invention is distinguished by the fact that the wall of the bag (S) comprises (SBa) a barrier layer situated between two polymer layers (S1) and (S2) which contains alumina, magnesium oxides, silicon oxides, titanium oxides, stannic oxides, zircon oxides or mixtures of these compounds.
    Among the group of metal oxides, silicon dioxide is particularly suitable for preventing the evaporation of the water contained in the preparation (A) through the bag (S).
    A particularly preferred product for the purposes of the invention is distinguished by the fact that the wall of the bag (S) comprises (SBa) a barrier layer located between the two polymer layers (S1) and (S2) which contains oxides of silicon.
    The barrier layer (SBa) may also comprise a thin layer of organic-inorganic hybrid polymers, polymers known in the specific literature by the technical term ORMOCER polymers. A typical ORMOCER polymer can be obtained, for example, by polycondensation of an organo-functional silane, e.g. eg, with an aluminum compound, and, if appropriate, with an inorganic oxide component. The corresponding syntheses are described, for example, in EP 0792846 B1 to which we make full reference herein. Inorgano-organic hybrid polymers (ORMOCER polymers) have both inorganic and organic crosslinked structures.
    It is possible to obtain the formation of an inorganic silicate network structure in a sol-gel process through controlled hydrolysis and condensation of silane alkoxides. The addition of additional metal alkoxides to the sol-gel process allows a targeted modification of the silicate network. Polymerization of organo-functional groups incorporated in the material with the aid of the organic alkoxysilanes makes it possible to form an additional organic network. The ORMOCER polymers obtained according to this process can be applied to the (S1) and / or (S2) layers, for example by using traditional techniques (spraying, coating, etc.).
    A product in the sense of the invention to be preferred is distinguished by the fact that the wall of the bag (S) comprises (SBa) a barrier layer located between two polymer layers (S1) and (S2) which contains one or more hybrid polymers inorgano-organic (ORMOCER polymers).
    In addition, it is also possible that the multilayer composite system (i.e. the multilayer composite film) which forms the wall of the bag is provided with a barrier layer (SBa) which comprises both inorganic oxide components inorganic-organic hybrid polymers (ORMOCER polymers). In addition, the barrier layer (SBa) may also comprise another organic polymer material which, itself, has no barrier effect but which, for example, increases the mechanical stability of the barrier layer, facilitates its formation. production or promotes a better adhesion of the layers (SBa) and (S1) and / or (S2) to the bonding.
    A particularly preferred product for the purposes of the invention is distinguished by the fact that the wall of the bag (S) comprises (SBa) a barrier layer situated between two polymer layers (S1) and (S2) which contains alumina, magnesium oxides, silicon oxides, titanium oxides, stannic oxides, zircon oxides or mixtures thereof and, in addition, one or more inorgano-organic hybrid polymers (ORMOCER polymers).
    The thicker the barrier layer, the greater the barrier effect against gases and water vapor is large or effective. Therefore, it is possible to choose the thickness of the barrier layer (SBa) depending on the desired barrier effect. For example, the layer thickness of the barrier layer (SBa) may be between 1 and 1000 nm (nanometers). Preferably, the layer thickness of the barrier layer (SBa) is between 5 and 500 nm, in particular between 10 and 250 nm and, particularly preferred, between 10 and 150 nm (nanometers).
    A particularly preferred product for the purposes of the invention is distinguished by the fact that the wall of the bag (S) comprises (SBa) a barrier layer located between the two polymer layers (S1) and (S2) and whose thickness is between 1 and 1000 nm (nanometers), preferably between 5 and 500 nm (nanometers), in particular between 10 and 250 nm (nanometers) and, particularly preferred, between 10 and 150 nm (nanometers).
    In addition to the layers (S1), (S2) and (SBa) described so far, the multilayer composite system within the meaning of the invention (that is to say the multilayer composite film) may comprise one or more layers additional. These additional layers may be, for example, intermediate layers (Cl) and / or bonding layers (CC1).
    For example, it is possible to provide the films with additional intermediate layers (C1) which increase the mechanical stability. The intermediate layers may also prevent or minimize the permeation of residual polymers or monomers of a polymer layer in the preparation (A).
    In order to increase adhesion in the composite system, the films may also include one or more bonding layers. Similarly, if a delamination between two layers (that is to say the detachment or the formation of an air bubble) is to be feared, it is possible to use also an additional bonding layer.
    A particularly preferred product for the purposes of the invention is distinguished by the fact that the wall of the bag (S) comprises, in addition to the first layer of a first polymer material (S1), the second layer of a second material (S2) and a barrier layer (SBa) still one or more other layers selected from - the intermediate layers (Cl) and / or - the bonding layers (CC)
