Description

The present application relates to multi-component packaging units for gentle color change of human hair. Furthermore, multi-stage processes for the application of these multi-component packaging units in the color change of human hair are described.

The dyeing of hair has always been the desire of many consumers, as this is on the one hand by covering of graying hair a rejuvenated appearance and on the other hand by fashionable coloring an individual type change is possible. By brightening a much desired bleaching of the hair can be achieved.

To provide color-modifying cosmetic agents, in particular for keratin-containing fibers such as human hair, the skilled person knows various systems depending on the requirements of the color change.

For permanent, intensive colorations with corresponding fastness properties, so-called oxidation colorants are used. Such colorants contain oxidation dye precursors, subdivided into so-called developer components and coupler components which under the influence of oxidants form the actual dyes with one another. The oxidation dyes are usually characterized by long-lasting dyeing results.

For temporary dyeings usually dyeing or tinting agents are used which contain so-called substantive dyes as a coloring component. These are dye molecules that attach directly to the substrate and do not require an oxidative process to form the paint. These two dyeing systems can also be combined to achieve specific nuances.

Finally, in particular natural shades can be achieved by air oxidation of so-called natural dye precursors based on indole derivatives.

The oxidizing agents contained in Blondiermitteln are able to lighten the hair fiber by the oxidative destruction of the hair dye melanin. For a moderate blonding effect, the use of hydrogen peroxide - optionally with the use of ammonia or other alkalizing agents - as the oxidant alone, for the achievement of a stronger Blondiereffektes usually a mixture of hydrogen peroxide and Peroxodisulfatsalzen and / or Peroxomonosulfatsalzen is used.

In particular, dyeing systems with dye precursors are, however, in need of improvement in terms of their fastness properties, in particular to weather influences, hair washes or other influences, such as sweat or swimming pool water. In particular, a constant, but noticeable decrease in staining by multiple, repeated hair washes after the staining treatment is undesirable because the result obtained initially by the staining changed over time.

Oxidative color changes are almost inevitably accompanied by damage to the hair, since the remaining structural constituents of the hair are oxidatively damaged. This damage effect is further enhanced by the mostly alkaline reaction medium. Depending on the severity of the degree of damage, this ranges from rough, brittle and difficult to comb hair over a reduced resistance and tear resistance of the hair to hair breakage. Usually this damage is counteracted by the use of aftertreatment agents, in particular conditioning agents. However, such conditioning usually does not completely restore hair to the pretreatment state. Accordingly, there continues to be a need for effective post-treatment agents.

It was therefore the object of the present invention to provide novel methods for changing the color of hair, which allow dyeings which are superior in their authenticity, in particular their washing resistance to the usual marketed agents. In addition, the oxidative color change should lead to no or only a reduced hair damage as possible.

As part of the investigations on the above object, it has now surprisingly been found that a color change process followed by a reductive aftertreatment leads to markedly improved fastness properties in oxidative dyeings and reduced damage to the hair, in particular the fiber structure, in oxidative color change treatments in general.

2. Application

2.1 Application Example 1 - Washing Resistance

Dyeing preparation (I) and oxidation preparation (III) were mixed in equal parts by weight to give a ready-to-use coloring agent. For the dyeing process, four times the amount of this application mixture was applied to hair strands (white, Euronaturhaar white (Kerling ENHw)) of about 0.7 g in weight. After a contact time of 30 min at 32 ° C, the tresses were washed with water and dried with a towel.

Immediately thereafter, the dyed streaks were treated with about 10 ml each of the conditioning preparations IIa to IIi. After an exposure time of 10 minutes at 32 ° C, the strands were rinsed with water and dried with a towel.

The tresses were then subjected to typical hair washes with a commercial shampoo.

Each strand of hair was colorimetrically measured after dyeing with subsequent treatment and after 6 washes with a colorimeter from Datacolor, type Spectraflash 450. As a measure of the dyeing power of the respective formulation, the ΔE value was used according to the following formula: ΔE = √ (ΔL) ² + (Δa) ² + (Δb) ² where ΔL, Δa and Δb represent the difference in L, a and b values, respectively, between untreated and untreated hair

For each recipe and each hair type was a double determination, from the individual values in each case the mean value was formed.

The ΔΔE value gives in each case the distance between the ΔE values before and after the hair washes. It is therefore a measure of the washing resistance of the dyeing. The smaller the ΔΔE value, the higher the washing resistance

The following results were obtained (Table 5): Number of washes L value a-value b-value AE value ΔΔE value untreated - 70.32 2.28 18.68 IIa 0 28,88 26.93 16.03 48.29 IIa 6 32.78 28.54 18.43 43.44 4.85 IIb 0 29.31 26.62 15.32 47.81 IIb 6 33.27 28.4 17.52 42.94 4.87 IIc 0 25.72 22.09 11.69 49,30 IIc 6 30.89 26.84 16.51 40.78 8.52 IId 0 25.96 24.28 12.70 49.88 IId 6 30.35 28.35 17.16 42.41 7.47 IIe 0 37.53 27.05 22.78 41,30 IIe 6 40.85 26.21 21.33 37.58 3.72 IIf 0 33.5 28.4 20.95 45,20 IIf 6 38.44 27.3 20.64 40.13 5.07 IIg 0 29.7 26.63 16.82 47,40 IIg 6 33.44 28.26 18.76 42.88 4.52 IIh 0 27.74 23.54 13.36 47.89 IIh 6 32,01 26,95 17.09 41.27 6.62 IIi (comparison) 0 24,08 19.99 10.52 50.18 IIi (comparison) 6 30.33 26.34 17.14 39.08 11.10

It is clear from the results that the wash stability of the dyeings increases markedly when an aftertreatment with a conditioning preparation according to the invention took place (in each case lower ΔΔE values compared with the comparison after treatment with IIi). The originally achieved color result is therefore more true to the aftertreatment according to the invention. When using ammonium thiolactate or concentrations of 1 or 2 wt .-% sodium dithionite in the conditioning preparation is still only a small color difference (ΔE value) over the non-inventive aftertreatment.

2.2 Application example 2 - Hair structure damage by means of NIR analysis

Hair can be damaged by oxidative treatment such as oxidative staining. Cystine is a component of human hair. At a wavelength of 6200 cm ^-1 to 5500 cm ^-1 cystine shows typical oscillations in the NIR spectrum (near-infra-red). The disulfide bridge contained in cystine can be oxidatively broken during a hair treatment, and the resulting thiol is converted by further oxidation into the sulfonic acid group of cysteic acid. Thus, the hair changes in its cysteic acid content, which increases with greater oxidative damage. Cysteic acid shows in the NIR spectrum at a wavelength of 5020 cm ^-1 - 4020 cm ^-1 . The decrease in cystine and the increase in cysteic acid, therefore, is an indicator of hair damage that can be determined by NIR analysis. A detailed description of the method can be found in Evaluation of Physical Properties of Human Hair by Diffuse Reflectance Near-Infrared Spectroscopy, Y. Miyamae, Y. Yamakawa and Y. Ozaki in Applied Spectroscopy, 2007, Vol. 61 (2), p. 212 ff ,

After averaging from 9 independent measurements was for light brown hair strands (Kerling EHN 6-0), dyed according to Example 2.1 and a post-treatment with the conditioning preparations IIa, IIb and IIi (10 wt .-% and 5 wt .-% ammonium thiolactate and Comparison), the respective amount of cysteic acid and thus determines the degree of damage of the strands. Number of washes NIR analysis value [mol cysteic acid / 100 mol amino acid] untreated - 0.6 IIa 0 0.9 IIb 0 1.1 IIi (comparison) 0 1.3 IIa 6 1.1 IIb 6 1.2 IIi (comparison) 6 1.3

The strands treated with the conditioning formulations of the present invention show a lower level of cysteic acid in the treated strands and therefore result in reduced hair damage.
