Definitions

  • the present invention is in the field of cosmetics and relates to a product for the oxidative color change of keratinic fibers, in particular human hair, which comprises a packaged in an oxidant-containing composition.
  • the oxidizer-containing composition contains at least one thickener.
  • the packaging is a packaging made from a special multilayer composite film system, the wall of which comprises at least two polymeric layers and a barrier layer. Here, the barrier layer has a fürerier für for gases and water vapor.
  • the packaging is a double-chamber sachet, also called a two-chamber bag.
  • the hair color can be changed temporarily.
  • already formed dyes diffuse from the colorant into the hair fiber.
  • the dyeing with substantive dyes is associated with little hair damage, but a disadvantage is the low durability and fast washability of the dyes obtained with substantive dyes.
  • oxidative color-change agents are usually employed.
  • oxidation colorants For permanent, intensive colorations with corresponding fastness properties, so-called oxidation colorants are used.
  • Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components, which under the influence of oxidants - usually hydrogen peroxide - form the actual dyes among each other. Oxidation dyes are characterized by excellent, long-lasting staining results.
  • oxidizing agents without the addition of oxidation dye precursors.
  • oxidizing agents for a medium Blondier soap the use of hydrogen peroxide as the oxidant alone is sufficient, for the achievement of a stronger Blondier bines usually a mixture of hydrogen peroxide and Peroxidisulfatsalzen is used.
  • Oxidative color changing agents usually come on the market in the form of two-component compositions, in which two different preparations are packaged separately in two separate packages and are mixed together only shortly before use.
  • the first preparation is a - usually acidified for stability reasons - formulation containing as oxidizing agent, for example, hydrogen peroxide in concentrations of 1, 5 to 12 wt .-%.
  • the oxidizing agent formulation is usually in the form of an emulsion or dispersion and is usually made available in a plastic bottle with a reclosable outlet opening (developer bottle).
  • This oxidizer formulation is mixed with a second formulation before use.
  • This second preparation is an alkaline formulation which is often in the form of a cream or gel and which also contains at least one oxidation dye precursor if, at the same time as brightening, a color change is desired.
  • This second preparation can be provided for example in the form of a tube or in the form of a plastic or glass container.
  • the second preparation which contains the alkalizing agent and / or the oxidation dye precursors, transferred from the tube or container in the developer bottle and then mixed by shaking with the already in the developer bottle hydrogen peroxide preparation.
  • the application mixture is prepared in the developer bottle.
  • the application on the hair then takes place via a small nozzle or outlet opening on the head of the developer bottle.
  • the spout is opened after spillage, and the application mixture can be removed by squeezing the flexible developer bottle.
  • the use of the developer bottle requires a certain amount of routine from the user, so that some users prefer to make the application mixture in a mixing bowl and apply it with a brush.
  • the application mixture is then removed via the brush from the mixing bowl.
  • packages in the form of bags or pouches, which as a rule are made of plastic films or even metal foils, are suitable as inexpensive packaging forms with low material consumption.
  • Such a packaging can be produced, for example, by gluing or hot-pressing two superimposed plastic films, the adhesion taking place on all edges of the films.
  • the interior of the package i.e., plastic bag
  • the opening of the package can be done by tearing or cutting the plastic bag.
  • Oxidizing agents are highly reactive substances which, depending on the storage conditions and, if appropriate, the presence of decomposing impurities, decompose in small amounts to form oxygen (i.e., gas).
  • developer bottles known from the prior art are filled with the oxidizing agent composition only a maximum of half, usually only one third, of their internal volume.
  • developer bottles are made of polyethylene. Since polyethylene is permeable to both water vapor and gases, there is no or very little overpressure in the developer bottle.
  • developer bottles are usually provided with stable, thick walls and a sturdy screw cap, so that the diffusion of water vapor or gases through the thickness of the walls is reduced and a slight pressure increase occurring within the bottle has no negative effects.
  • bag-shaped packages are, however, usually filled completely with the liquid preparation, and in the filled bag there is virtually no supernatant airspace.
  • packages should be flexible, and upon opening (e.g., tearing or slicing), there should be no uncontrolled discharge of the preparation. For this reason, in the packaging of liquid preparations, the emergence of overpressure in the packaging should be avoided as far as possible.
  • Oxidizing agent composition If an oxidizing agent composition is present in such a packaging, the gas (oxygen) produced during storage may cause the packaging to expand. Since the edges of the package are usually only glued, a strong swelling at worst leads to bursting of the packaging. For these reasons, during storage of Oxidizing agent-containing compositions of great importance in the choice of the film material that makes up the packaging.
  • Packaging made of pure plastic, such as polyethylene or polypropylene, is permeable to both water vapor and gases.
  • an oxidant-containing preparations in a package made of polyethylene or polypropylene therefore, no inflation of the packaging. Due to the high permeability of the relatively thin film of the packaging to water vapor, however, the water content of the preparation is reduced. If the preparation is stored in the packaging for a few weeks to months, the loss of water exceeds the maximum permitted for sufficient storage stability.
  • Completely airtight packages are made, for example, from plastic films having a lamination with a metal layer, for example, with an aluminum layer. These packages are impermeable to water vapor and gases. If these packages are filled with an oxidizing agent-containing preparation, the gas produced during the decomposition of the oxidizing agent can not escape, the package expands as described above and can delaminate or even burst.
  • the object of the present application was to pack hair dye formulations so that the mechanical strength of the package is sufficiently large, a safe and space-saving storage can be made possible, with an easy accessibility to the ingredients should be guaranteed.
  • oxidizer-containing compositions can be packaged in which the water vapor permeability is low and puffing can thereby be reduced by allowing the film oxygen permeability.
