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 oxidizing agent-containing composition contains certain thickening agents and anionic surfactants.
  • the packaging is a packaging made of a special multilayer composite film system, the wall of which comprises at least two polymeric layers and a Barierre layer.
  • the barrier layer has a natural
  • 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 with one another. 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 provided 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 shaking 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.
  • the use of a voluminous and expensive developer bottle is not necessary and it will still sought after inexpensive and material-saving packaging forms for the preparation of the oxidizing agent.

  • 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 sturdy, thick walls and a sturdy screw closure, so that the diffusion of water vapor or gases through the thickness of the walls is reduced and a slight increase in pressure inside the bottle has no negative effects.
  • 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 inflates as described above and can burst.
  • the object of the present application was to pack the oxidizing agent composition inexpensive, material-saving, space-saving, safe and in particular storage-stable.
  • compositions containing oxidizing agents can be packaged in a storage-stable manner if, on the one hand, special packages are used which consist of special composite film systems and additionally have a barrier layer. On the other hand, the oxidizing agent preparation must be thickened with special thickening agents.

L'emballage est constitué d'une feuille multicouches (F) comprenant au moins deux couches de polymère (P1) et (P2) et au moins une couche barrière (BS). La composition cosmétique comprend au moins un agent oxydant et au moins un agent épaississant, ainsi qu'au moins un tensioactif anionique.
