Description

The Invention relates to hair dyeing and hair tinting, which special indophenols and / or special indoanilines as substantive Dyes are added.

preparations to sound and dyeing Hair is an important type of cosmetic. she can serve the natural Hair color according to the wishes of the slightly or more closely to the corresponding person, a completely different one To achieve hair color or unwanted shades, like gray tones, to cover. Usual hair dye be, depending on the desired Color or durability of the color, either based on oxidation dyes or based on formulated direct dyes. Frequently also combinations become of oxidation dyes and direct dyes to achieve special nuances used.

Quality Dyes are characterized by high color strength. Continue to be good welding, Wash and light fastness desired. Furthermore, they should be toxicologically and dermatologically be harmless. It is also beneficial if the substances a high solubility in different basic formulations.

dye based on oxidation dyes lead to brilliant and lasting Colors. However, they require the use of strong oxidants, such as for example, hydrogen peroxide solutions. This can be the hair to be dyed damage. These damages must then be counteracted with appropriate care products. Furthermore can Contacts the skin with these stains lead to adverse reactions in very sensitive people.

dye based on substantive dyes come without oxidizing agent out and can at be formulated pH values in the region of the neutral point. A major disadvantage the colorant based on direct dyes is the low wash fastness the obtained dyeings. The wind up of the dye molecules on the hair as well as the shine of the dyed hair can in many cases also not fully satisfied.

When direct dyes are often 2-nitro-p-phenylenediamine derivatives used. However, these derivatives are often insufficient in water soluble or dispersible. If the dye can not be solubilized in the staining medium is, leads this to uneven dyeings and there is a high risk, only weak colorations to reach.

to Improvement of equalization as well as extension of the nuance spectrum direct dyes are often also in oxidation hair colors used. However, the usually used direct-pulling Dyes only a low stability against reducing and oxidizing agents on.

There the direct dyes of the prior art not yet are optimal in every respect, there is still a need to find new ones to develop substantive dyes that are as described above Do not have disadvantages and at the same time intense colorations result.

It was now surprisingly found that certain indophenols and / or specific indoanilines the requirements placed on substantive dyes in one high dimensions fulfill.

The hair colorants according to the invention contain both the developer components and the coupler components preferably in an amount of 0.005 to 20 wt .-%, each based on the dye without the oxidizing agent preparation. These are developer components and coupler components generally in approximately molar amounts to one another used. If the molar use proved to be useful has, so is a certain surplus individual oxidation dye precursors not disadvantageous, so that Developer components and coupler components in a molar ratio of 1: 0.5 to 1: 2 may be included.

It it is not necessary that the oxidation dye precursors or the direct dyes in each case uniform compounds represent. Rather, you can in the hair colorants according to the invention by the manufacturing processes for the individual dyes, be contained in minor amounts still other components as far as these are not the dyeing result adversely affect or for other reasons, eg. B. toxicological, must be excluded.

Regarding the in the hair dyeing and -tönungsmitteln applicable dyes is still expressly on the monograph Ch.

It is possible in principle, the agents according to the invention formulated so that they either remain on the hair or rinsed out of the hair again become.

It has also been found to be particularly preferred when the agents according to the invention or the agents used according to the invention are free from Bis- (2-hydroxy-5-aminophenyl) -methane and N, N'-bis (2-hydroxy-5-aminobenzyl) piperazine and their salts are.

Farther It has proved to be particularly preferred when the compounds of the formula (I) in the compositions of the invention or in the invention used Funds are distributed inhomogeneously. An inhomogeneous distribution lies according to the invention then, when the content of the compounds of the formula (I) taken at 3 Samples (20mg each) by ± 2%, preferably by ± 5%, most preferably by ± 10%, fluctuates.

According to one preferred embodiment are the agents of the invention formulated so that they can remain on the hair. This is the case in particular with the so-called tinting agents, but also with funds, as well exercise a firming function should.

All Quantities in the description relate, so far not explicitly defined differently, in each case on the finished application preparation.

The The following examples are intended to explain the subject matter of the invention in more detail.

1 bis - {[5- (2-amino-5-methyl-4-oxocyclohexa-2,5-dien-1-ylidene) -amino] -2-hydroxyphenyl} -methane

1.1 Structure

1.2 Synthesis

1:32 g (11 mmol) of 3-amino-6-methylphenol and 1.50 g (5 mmol) of 4-amino-2- (5-amino-2-hydroxybenzyl) phenol were placed in 100 ml of methanol before adding to the resulting solution 1.5 g of calcium hypochlorite were added. The reaction mixture was at 20 ° C touched, being the solution quickly dark blue colored. To 2 and after 3 hours to the reaction mixture was still 0.75 added calcium hypochlorite.

To 4 hours, the reaction mixture was diluted with 200 ml of methanol and then first over one Pleated filter and then over silica gel filtered. In the course of this filtration, the color of the solution of blue to red. The collected filtrate was completely concentrated under vacuum and the remaining residue recrystallized from methanol. It became a dark rust red solid receive.

Yield: 1.60 g (68%)

Melting point:> 316 ° C

¹ H-NMR (400 MHz, DMSO-d ₆ ) δ = 1.76 (s, 6H), 3.85 (s, 2H), 5.53 (s, 2H), 6.61 (s, 2H), 6.63 (d, 2H), 6.70 (dd, 6H), 6.98 (d, 2H), 9.90 (s, 2H).

1.3 coloration

The following coloring cream was made: Hydrenol D ^® 6.0 g Lorol ^® (technical) 6.0 g Eumulgin ^® RH 40 1.0 g Eumulgin ^® B1 3.0 g Eumulgin ^® B2 3.0 g PHB Methylester 0.3 g PHB propyl 0.2 g phenoxyethanol 1.0 g Polydiol 400 5.0 g Bis - {[5- (2-Amino-5-methyl-4-oxocyclohexa-2,5-dien-1-ylidene) amino] -2-hydroxy-phenyl} -methane 1.0 g ammonium sulfate 1.0 g (in 30.0 g of water) Natrosol ^® 250 HR 1.0 g (in 15.0 g of water) NaOH 0.1% ad pH 9 water ad 100

The The first nine components were melted together at 80 ° C, after which the dye added. This mixture was mixed with a solution of the ammonium sulfate emulsified in 30 g of water. Subsequently was added a swell of 1.0 g of Natrosol 250 HR in 15.0 g of water. The pH stated in the table was 0.1% sodium hydroxide solution set, then was made up to 100 g with water.

1.8 g of the coloring cream were on a ca. 6 cm long strand of human hair (Kerling Euronatur hair, 80% gray, not specially pretreated) and there for 30 minutes at 30 ° C leave. After the exposure time, the hair was rinsed, with a usual one Washed shampoo and then dried. The hair received a reddish brown color.
