Definitions

  • the present invention relates to a special application device for applying an application liquid to keratinic fibers, in particular a liquid dyeing preparation, based on oxidation dye precursors.
  • Human hair as an example of a keratin fiber is treated today in many ways with hair cosmetic preparations. These include, for example, the cleansing of hair with shampoos, the care and regeneration with rinses and cures and the bleaching, dyeing and shaping of the hair with dyes, tinting agents, waving agents and styling preparations. In this case, means for changing or nuancing the color of the head hair play a prominent role.
  • dyeing or tinting agents which contain as coloring component so-called substantive dyes. These are dye molecules that attach directly to the hair and do not require an oxidative process to form the paint. These dyes include, for example, the henna already known from antiquity for coloring body and hair. These dyeings are usually prone to shampooing, so that sometimes after a few washes an undesirable nuance shift or even a visible "discoloration" occurs.
  • oxidation colorants For permanent, intensive dyeings with corresponding fastness properties, so-called oxidation colorants are used. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components. The developer components form under the influence of oxidizing agents or of atmospheric oxygen with one another or with coupling with one or more coupler components, the actual dyes.
  • the oxidation stains are characterized by excellent, long lasting staining results.
  • a mixture of a larger number of oxidation dye precursors must usually be used; In many cases, direct dyes are still used for shading.
  • the colorants of the three categories described in the form of creams, gels or solutions are usually applied to the fibers with the aid of a brush.
  • dyes that are applied to the fibers as a shampoo formulation or conditioner formulation.
  • DE 199 22 092 A1 describes, for example, a cap-like application device for dyeing hair strands, which is placed on an associated container with hair dye.
  • This application device comprises a plurality of outlet openings for applying the hair dye and adjacent thereto guide prongs, which are drawn during use with combing movements through the hair.
  • bristles are arranged around the outlet opening in order to achieve a more uniform application of the hair dye. Nevertheless, the outlet openings with the bristles do not allow a sufficiently metered application of the hair dye. In particular, an excessive leakage of the hair dye and thus also an unwanted wetting of the scalp can not be effectively excluded. It was therefore an object of the present invention to develop a dyeing system which makes it possible to prepare dyeing agents based on oxidation dye precursors until they are used separately and still allows easy handling by the consumer. In addition, the dyeing properties of the application device should also convince.
  • a first subject of the present invention is therefore an application device for applying an application liquid to keratinic fibers, in particular hair, with at least one container for receiving the application liquid, with an application head which is connected to the at least one container and has a porous application body for applying the Application liquid by sweeping the fibers, wherein the application liquid contains the application liquid at least one oxidation dye precursor and is mixed with an oxidizing agent preparation immediately before use.

  • Swelling and penetration substances such as glycerol, propylene glycol monoethyl ether, carbonates,
  • Opacifiers such as latex, styrene / PVP and styrene / acrylamide copolymers
  • Pearlescing agents such as ethylene glycol mono- and distearate and PEG-3-distearate,
  • Propellants such as propane-butane mixtures, N 2 O, dimethyl ether, CO 2 and air,
  • the constituents of the water-containing carrier are used to prepare the inventive application liquid in amounts customary for this purpose;
  • emulsifiers are used in concentrations of 0.5 to 30 wt .-% and thickening agents in concentrations of 0.1 to 25 wt .-% of the total colorant.
  • the application device 1 shown in FIG. 1 is designed for use with a liquid hair dye. In principle, however, such an application device 1 can also generally serve for the application of any application fluid for keratinic fibers, the application fluid being applied by brushing movements to the fibers.
  • the application device 1 has a container 2 which receives the hair dye or the application liquid and stores it until it is used. For this purpose, it may be useful to provide an absorbent storage element in the interior of the container, which is designed, for example, as a fibrous or sponge-shaped, in order to receive the hair dye or the application liquid.
  • the container 2 has two separate areas inside. In the first, larger area, the application liquid is prepared before the application. In the second, smaller area, the powdery oxidizing agent preparation is formulated before the application. Immediately before the application, the partition wall between the two areas is pierced by an externally actuated mandrel, so that there is a mixing of the two separately assembled components. In this embodiment, the container 2 thus serves the separate packaging, the mixture of the components and also as a storage container during use.
  • FIG. 1 shows the application device 1 in the ready-to-use operating position, ie. H. with open application head 3. Outside the application times, the application head 3 is covered by a cap, not shown, which is attached, for example, to a thread 4 on the container 2. Thus, the application head 3 is sealed from the environment, so that drying of the liquid hair dye is effectively prevented.
  • the applicator body 31 communicates with the liquid hair dye or the application liquid in conjunction to the liquid in the manner of a wick To promote capillary action from the container and to provide for the application to the hair.
  • the porous application body 31 has a material structure with continuous pores in order to achieve the corresponding capillary action.
  • the application body 31 consists in particular of a fibrous, sponge, foam, felt or sintered material-like material. The advantage of such a designed applicator body 31 is not only in the reliable promotion of the hair dye but also in the high fluid absorbency. Namely, the high liquid absorption capability prevents unwanted leakage or dripping of the hair dye from the application device 1.
  • the application body 31 is preferably block-shaped (not shown) or designed with a plurality of pin-shaped projections 32.
  • the embodiment with a plurality of pin-shaped projections 32 increases the effective surface of the application body 31, so that better coloring results are achieved when sweeping the hair.
  • the comb teeth 33 which are likewise formed immediately adjacent to the application body 31 on the application head 3, are used for disentangling the hair during application of the application device 1. This disentangling of the hair results in a more uniform application of the color to the hair.
  • the individual comb teeth 33 are integrally connected to at least one comb element 34 in order to simplify handling and production in general. Furthermore, it makes sense to attach the comb teeth 33 or comb elements 34 releasably to the application head 3, in order to permit an application without comb teeth 33 or comb elements 34, depending on the particular case of use.
  • the comb teeth 33 protrude in the longitudinal direction of the application device 1 with respect to the application body 31 in order to prevent contact of the scalp with the application body 31 or the application fluid, especially in hair applications.
  • the comb teeth 33 are arranged in a circle around the applicator body 31 lying around on the application head 3.
  • the hair is first unraveled during the application of the application device 1, regardless of the respective coating movement direction, before the actual application of the hair dye takes place. This gives improved staining results. 2 application liquids
  • the resulting colorant was mixed with percarbamide in the mixing ratio of colorant: developer 10: 1 immediately before use as described above. Subsequently, the application liquid was applied with the application device according to the invention on the fibers and rinsed after a contact time of 30 minutes.
