Description

SPECIFICATION Process for dyeing human hair and composition for carrying out this process This invention provides a process for dyeing human hair and an agent (i.e. a composition) for carrying out this process.
Agents for changing the color of hair by bleaching (to produce a blond effect) and dyeing are known, and are described, for example, in Ullmanns Encyklopädie der technischen Chemie, 4th Edition, Volume 12, pages 435-441.
The present invention arose from the problem of providing a versatile process, and agents, for dyeing human hair, by which human hair can be dyed in colors from pale yellow to yellow and from brown to reddish brown, the agents being intended to possess particularly good physiological toleration and toxicological safety. Desired hair dyeings should be obtainable by combination with direct dyes or by combination with dye precursors and oxidizing agents.
More particularly, hair-dyeing agents were sought which have the following propertiest 1. They should make it possible to dye human hair directly in yellow to brown colors without requiring oxidizing agents and/or dye precursors, it being moreover desirable that such hair dyeing can be carried out both in an alkaline medium, up to pH 11, and in an acid medium, up to pH 5. Further it is desirable, in order to provide further dyeing capabilities, that the agents should be combinable with direct hair dyes, to allow any desired hair dyeings to be obtained.
2. The agents should be combinable with the conventional oxidizing agents based on hydrogen peroxide, for the purpose of obtaining brown hair dyeings.
3. The agents should be combinable with dye precursors and hydrogen peroxide in order to allow any desired dyeings to be produced, including both darker hues and lighter hues than the initial hue of the hair.
The invention provides a process for dyeing human hair, which employs a) a hydroxybenzaldehyde in solution, b) if appropriate, an oxidizing agent, c) if appropriate, a known precursor for hair dyes, d) if appropriate, a direct dye and e) if appropriate, conventional additives, wherein the hydroxybenzaldehyde employed is a compound of the formula (I)
where R, represents a hydrogen atom or the OH group, R2 represents an OCH3 group or a hydrogen atom, R3 represents an OCH3 group, an OH group or a hydrogen atom and R4 represents an OCH3 group or a hydrogen atom, with the proviso that only one of R1 and R3 can be an OH group.
The invention further provides an agent for dyeing human hair, for carrying out the above process, comprising a) a hydroxy benzaldehyde in solution, b) if appropriate, a known precursor tor hair dyes, c) if appropriate, a direct dye and d) if appropriate, conventional additives, wherein the hydroxybenzaldehyde employed is a compound of the formula

and/or one or more acid addition salts of the above compounds.In formula (II), R1, R2 and R3 are identical or different and each represents a hydrogen atom or an alkyl or alkoxy radical having 1 or 2 carbon atoms, and R4 and R5 are identical or different and each represents a hydrogen atom or an alkyl, hydroxyalkyl, alkoxyalkyl (the alkoxy radical having 1 or 2 carbon atoms), carbamylalkyl, mesylaminoalkyl, acetylaminoalkyl, ureidoalkyl or carbethoxyaminoalkyl radical (the alkyl radicals in R4 and R5 having 1 to 3 carbon atoms), with the proviso that R1 or R3 is a hydrogen atom if R4 and R5 are not hydrogen atoms.

Compounds of the formula (I) include 4-hydroxy-3-methoxy-benzaldehyde, 2-hydroxy-5-methoxy benza Idehyde, 2-hydroxy-4-methoxy-benzaldehyde and 2-hydroxy-3-methoxy-benzaldehyde.
The dyeing agent of the invention can be in the form of a solution, paste, cream or jelly or in any other formulation which is suitable for dyeing human hair and is commercially available as, for example, a hair dyeing agent, hair toner, toning fixer and hair rinse.
In order to show that dilute solutions of the compounds of the formula (I) make it possible to dye human hair even in the absence of oxidizing agents, the following tests were carried out, it being particularly noteworthy that the dyeings can be carried out in a pH range of about 5 to about 11 (with the exception of when 2-hydroxy-4-methoxy-benzaldehyde and 4-hydroxy-3-methoxy-benzaldehyde are used).
Test 1 for dyeing strands of human hair with 2-hydroxy-s-methoxy-benzaldehyde 2-Hydroxy-3-methoxy-benzaldehyde was dissolved, at various concentratons, in a solution consisting of 47% by weight of water, 47% by weight of 2-propanol and 6% by weight of 25% strength NH3, and the strands of human hair were in each case treated with the solution for 30 minutes at room temperature.The results are shown in Table I: Table I Concentration of 2-hydroxy- Result of dyeing (in the 3-methoxy-benzaldehyde absence of an oxidizing agent) 0.1% by weight pale yellow 0.2% by weight somewhat more pronounced pale yellow 0.5% by weight stronger yellow 1.0% by weight good yellow 2.0% by weight - yellow 5.0% by weight yellow (as for the 2% strength by weight solution) At 2% by weight of 2-hydroxy-3-methoxy-benzaldehyde in the solution used, the optimum saturation limit of the dyeing is reached. Similar results were obtained on using 2-hydroxy4-methoxybenzaldehyde or 2-hydroxy-5-methoxy-benzaldehyde.
The tests which follow show that dilute solutions of 4-hydroxy-3-methoxy-benzaldehyde, 2hydroxy-3-methoxy-benzaldehyde, 2-hydroxy-5-methoxy-benzaldehyde or 2-hydroxy4-methoxybenzaldehyde can also be used in combination with oxidizing agents for dyeing human hair.

The concentration of the additional dye precursor was 1.0% by weight in each case.

In each case, hair strands dyed yellow were obtained.

EXAMPLE 5 A toner is prepared from the following recipe: 2-Hydroxy-5-methoxy-benzaldehyde 0.70 9 Basic Blue 99 (Color Index 56059) 0.20 9 Basic Brown 16 (Color Index 12250) 0.50 9 Basic Red 22 (Color Index 11055) 0.10 9 2-Propanol 10.00 9 Hydroxyethylcellulose 1.00 9 Glycerol, German Pharmacopoeia 7 3.00 9 Monoethanolamine 1.00 9 Potassium hydroxide solution (51% strength) 2.00 9 Perfume 0.30 9 Desalinated water 81.20 g 100.00g The pH value is adjusted to 8.0-8.5.
The above toner can be packaged in a known manner in aerosol cans, using a propellant. For use, the toner is sprayed on to the hair, thereby giving these a reddish brown tone.

The toner can be packaged and used as described in Example 5. This gives the hair a greenish blond tone, so that the toner has an anti-red effect.
EXAMPLE 7 A toner is prepared from the following recipe: 2-Hydroxy-5-methoxy-benzaldehyde 0.70 g Basic Brown 16 (Color Index 12250) 0.50 g Basic Blue 99 (Color Index 56059) 0.10 9 2-Propanol 10.00g Hydroxyethylcellulose 1.00 g Glycerol, German Pharmacopoeia 7 3.00 g Monoethanolamine 1.00 g Potassium hydroxide solution (51% strength) 2.00 g Perfume 0.30 g Desalinated water 81.40g 100.00 g The pH value is adjusted to 8.0-8.5.
The toner can be packaged and used as described in Example 5. This gives the hair a light blond tone.
German Auslegeschrift 1,106,925 describes a process for dyeing human hair, using an agent in which the active ingredient is an ortho-dihydroxybenzene compound, protocatechualdehyde being the preferred active ingredient (compare loc. cit., column 2, lines 49-52, column 5 and Example 6) and the dyeing being effected by using an alkali metal periodate and/or ammonium periodate and/or ammonium persulfate as the oxidizing agent.German Auslegeschrift 1,106,925 does not give a prior description of, or even make obvious, the possible use of 2-hydroxy-3-methoxy-benzaldehyde, 2-hydroxy-4-methoxy benzaldehyde or 2-hydroxy-5-methoxy-benzaldehyde by themselves, or of 4-hydroxy-3-methoxy benzaldehyde, 2-hydroxy-3-methoxy-benzaldehyde, 2-hydroxy-4-methoxy-benza Idehyde or 2hydroxy 5-methoxy-benzaldehyde in combination with an oxidizing agent for the purpose of producing dyeings on human hair.
It is surprising that, in the present invention, a yellow dyeing can be produced on human hair by means of 2-hydroxy-3-methoxy-benzaldehyde, 2-hydroxy-4-methoxy-benzaldehyde and 2-hydroxy-5methoxy-benzaldehyde without using an oxidizing agent, whilst protocatechualdehyde does not produce a dyeing under these conditions. It is even more surprising that in the presence of oxidizing agents protocatechualdehyde gives reddish-brown or medium brown hair dyeing only under quite specific conditions (in respect of oxidizing agent and pH value); however, under the conditions required for protocatechualdehyde, brown hair dyeings cannot be achieved with 4-hydroxy-3-methoxy benzaldehyde, 2-hydroxy-3-methoxy-benzaldehyde, 2-hydroxy-4-methoxy-benzaldehyde or 2-hydroxy5-methoxy-benzaldehyde.
The table which follows is intended to make clear the surprising results of the comparative investigations.
