Description

The present invention relates to a kit of parts containing a cosmetic agent containing at least one cationic keratin hydroxylate and an oxidizing agent preparation containing a specific amount of oxidizing agent.

Moreover, the present invention relates to a method for dyeing keratinic fibers using the packaging unit according to the invention.

Furthermore, the present invention relates to the use of the packaging unit according to the invention for increasing the care keratinischer fibers.

The change in the shape and color of hair represents an important area of modern cosmetics. Thus, the appearance of the hair can be adapted to current fashion trends as well as to the individual needs of the individual consumer. The fashionable color design of hairstyles or the lamination of gray or white hair with fashionable or natural tones is usually done with color-changing agents. In addition to the desired dyeing power, these agents should cause the least possible damage to the hair, and preferably possess additional care properties.

To provide color-modifying cosmetic agents, especially for the skin or keratin-containing fibers, such as human hair, various dyeing systems are known in the art.

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. The developer components form the actual dyes under the influence of oxidizing agents or of atmospheric oxygen with one another or with coupling with one or more coupler components. The oxidation dyes are characterized by excellent, long-lasting dyeing results. For naturally acting dyeings, however, it is usually necessary to use a mixture of a larger number of oxidation dye precursors; In many cases, direct dyes are still used for shading. If the dyes formed or used directly in the course of color formation have significantly different fastnesses (eg UV stability, perspiration fastness, wash fastness, etc.), a discernible and generally undesirable color shift can occur over time. This phenomenon is more pronounced when staining hairs or haircuts with different degrees of damage. An example of this is long hair, in which the hair tips are usually much more damaged than the freshly regrown hair zones.

For temporary dyeings usually dyeing or tinting agents are used which contain so-called direct drawers as coloring component. These are dye molecules that grow directly onto the substrate 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 generally much more sensitive to shampooing than oxidative dyeings, so that much earlier an often undesirable change in shade or a visible homogeneous color loss occurs.

Finally, another dyeing process has received much attention. In this method, precursors of the natural hair dye melanin are applied to the substrate, e.g. Hair, applied; These then form naturally-analogous dyes in the course of oxidative processes in the hair. In such processes, for example, 5,6-dihydroxyindoline is used as the dye precursor. In particular, with multiple use of agents with 5,6-dihydroxyindoline, it is possible to restore the natural hair color in persons with graying hair. The coloration can be carried out with atmospheric oxygen as the sole oxidant, so that can be dispensed with further oxidizing agent. In individuals originally of mid-blond to brown hair, 5,6-dihydroxyindoline can be used as the sole dye precursor. On the other hand, satisfactory results can often only be achieved for use in persons with originally red and, in particular, dark to black hair color, by using other dye components, in particular special oxidation dye precursors.

In particular, oxidative hair dyes are disadvantageous to the user despite their advantageous dyeing properties.

On the one hand, the use of the oxidizing agent for coloration or development of the actual dyeing leads to damage in the hair structure and on the hair surface. The hair becomes brittle, its elasticity decreases and the combability decreases.

On the other hand, oxidative colorants generally require a basic pH for the coloration, in particular between pH 9.0 and pH 11.5. These pH values are necessary to ensure an opening of the outer cuticle (cuticle) and to allow penetration of the dye precursors and / or the oxidizing agent into the hair. The spreading of the outer cuticle layer leads to an unpleasant surface sensation of the hair and thus to a deteriorated combability in the wet and dry state. As a result, there is an increased need for the consumer to use additional aftertreatment agents, such as conditioning agents.

In order to improve the care state of the fibers, it has long been customary to subject the fibers to a special post-treatment after the color-changing treatment. Here, usually treated in the form of a rinse, the hair with special active ingredients. Depending on the formulation, this treatment improves combability, hold and fullness of the hair and reduces the split rate. In order to reduce the expense of the usual multi-stage process, especially in the direct application by consumers, so-called combination preparations have recently been developed. In addition to the customary components, for example for dyeing the hair, these preparations additionally contain hair conditioning and / or hair conditioning active ingredients. However, the nourishing properties of these agents are not always satisfactory, especially on hard-to-care fibers.

There is therefore still a need for suitable stable care substances which can be incorporated into oxidative colorants and thus minimize damage already occurring during the dyeing process.

It is an object of the present invention to provide a kit of parts for coloring keratinous fibers which avoids or at least mitigates the disadvantages of the prior art and which results in reduced fiber damage, ie. H. improved care of keratinic fibers results.

It has now surprisingly been found that the use of at least one cationic keratin hydrolyzate in a packaging unit for coloring keratinic fibers results in a reduced damage to the fibers and thus in improved care, in particular in improved combability, during the lightening of keratinic fibers. In the context of the present invention, lightening is to be understood as meaning the lightening of the hair by at least one color shade.

2. Increasing the volume of dyed strands of hair

For the preparation of the oxidative colorants for determining the volume, the cosmetic agents V1 and E1 and E2 were each mixed in a weight ratio of 1: 1 with the above oxidizing agent preparation O1.

12 strands of naturally European hair (Kerling International, lot # 05/2011, N111, length 12 cm, weight 1 g, Backnang, Germany) were washed with an aqueous sodium lauryl ether sulfate solution (3% active substance content in the solution). The tresses were air-dried and stored for 24 h at 25 ° C and 25% relative humidity. After soaking these strands for 5 minutes in water their combability was determined (reference value).

For the dyeings, 12 strands of naturally European hair (Kerling International, lot # 05/2011, N111, length 12 cm, weight 1 g, Backnang, Germany) were used per oxidative dye. For this purpose, in each case 4 g of the previously prepared oxidative colorants per 1 g of hair strand were applied. After streaks were dyed at 32 ° C for 30 minutes, they were rinsed with water for 2 minutes and air-dried (bleaches: blond).

• – Shapiro-Wilks Test (Test für Normalverteilung)
• – Ausreißertest nach Grubbs
• – Bartlett-Test (Test auf Homoskedastizität von Varianzen)
• – Univarianter Signifikanztest
• – Newman-Keuls Test (Bestimmung von signifikanten Unterschieden)
• – Kruskal-Wallis Test (parameterfreie Analyse der Rangvarianz)
• – Siegel-Castellan Test (Mehrfachvergleiche von p-Werten nach Rang, nichtparametrisch)

The measurement of combability was carried out as follows:
Before the measurement, each tress was moistened with combing with a hard rubber crest with fine teeth (Hercules Sägemann, Hamburg Germany) for 2 seconds with water. After 3 combing operations have been performed, the combing force is measured during a further 10 combing operations, whereby the respective hair strand rotates slowly during the combing process. The resulting measurements are compared using the following statistical tests embedded in Statistica 10.0 software (StatSoft Inc., USA):

• - Shapiro-Wilks test (test for normal distribution)
• - Outlier test after Grubbs
• - Bartlett test (test for homoskedasticity of variances)
• - Univariant significance test
• - Newman-Keuls test (determination of significant differences)
• - Kruskal-Wallis test (parameter-free analysis of rank variance)
• - Siegel-Castellan test (multiple comparisons of p-values by rank, nonparametric)

The change in the combing force dK in percent can be calculated with the aid of the formula dK = [(K ₀ -K _i ) / K ₀ ] x 100. K0 is the mean value of the combing force for the unstained hair strands and Ki the mean value for the hair strands treated with the respective oxidative colorant.

The care of the strands of hair is all the higher, the lower the combing force and thus the greater the change in the combing force. Table 1 shows the dK values for the colorations using the cosmetic agents V1, E1 and E2. The colorations with the cosmetic products E1 and E2 according to the invention, which contain at least one cationic keratin hydrolyzate in a total amount of 0.5% by weight and 1.3% by weight respectively, have in comparison to a coloration without cationic keratin hydrolyzate (V1) a lower combing power and thus a significantly improved care. The use according to the invention of at least one cationic keratin hydrolyzate in hair colorants, especially in the case of lightening dyeings, leads to a significantly improved care compared to oxidative colorants which contain no cationic keratin hydrolysates. Oxidative dye dK [%] V1 + O1 (1: 1) 2 E1 + O1 (1: 1) 16 E2 + O1 (1: 1) 12
