Description

Use of Unsaturated Aldehydes in Dying Fibres Containing Keratin This invention relates to the use of unsaturated aldehydes for colouring keratin-containing fibres, more especially human hair.

In general, keratin-containing fibres, for example hair, wool or pelts, are dyed either with substantive dyes or with oxidation dyes which are formed by oxidative coupling of one or more primary intermediates with one another or with one or more secondary intermediates. Primary and secondary intermediates are also known as oxidation dye precursors.

The primary intermediates normally used are primary aromatic amines containing another free or substituted or amino group in the para or ortho position, diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazolone derivatives and 2,4,5,6-tetraaminopyrimidine and derivatives thereof.

Special representatives are, for example, p-phenylenediamine, p-toluylenediamine, paminophenol, o-aminophenol, 1-(2'-hydroxyethyl)-2,5-diaminobenzene, N,N-bis-(2-hydroxyethyl)-pphenylenediamine, 2-(2,5-diaminophenoxy)-ethanol, 1-phenyl-3-carboxyamido-4-amino-5-pyrazolone, 4-amino-3-methylphenol, 2,4,5,6-tetraaminopyrimidine, 2-hydroxy-4,5,6-triaminopyrimidine, 4hydroxy-2,5,6-triaminopyrimidine, 2,4-dihydroxy-5,6-diaminopyrimidine, 2-dimethylamino-4,5,6triaminopyrimidine, 2-hydroxyethylaminomethyl-4-aminophenol, 4,4'-diaminodiphenylamine, 4-amino- 3-fluorophenol, 2-aminomethyl-4-aminophenol, 2-hydroxymethyl-4-aminophenol, aminophenyl)-methane, 1,4-bis-(4-aminophenyl)-diazacycloheptane, 1,3-bis-(N-(2-hydroxyethyl)-N-(4aminophenylamino))-2-propanol, 4-amino-2-(2-hydroxyethoxy)-phenol and derivatives according to EP 0 740 741 or WO 94/08970, for example 4,5-diamino-1-(2'-hydroxyethyl)pyrazole.

The secondary intermediates used are generally m-phenylenediamine derivatives, naphthols, resorcinol and resorcinol derivatives, pyrazalones and m-aminophenols. Particularly suitable secondary intermediates are 1-naphthol, pyrogallol, 2,7- and 1,7-dihydroxynaphthalene, oaminophenol, 5-amino-2-methylphenol, m-aminophenol, resorcinol, resorcinol monomethyl ether, mphenylenediamine, 1-phenyl-3-methyl-5-pyrazalone, 2,4-dichloro-3-aminophenol, 1,3-bis-(2,4diaminophenoxy)-propane, 4-chlororesorcinol, 2-chloro-6-methyl-3-aminophenol, 2-methyl resorcinol, resorcinol, 2,5-dimethyl resorcinol, 2,6-dihydroxypyridine, 2,6-diaminopyridine, 2-amino-3hydroxypyridine, 2,6-dihydroxy-3,4-diaminopyridine, 3-amino-2-methylamino-6-methoxypyridine, 4amino-2-hydroxytoluene, 2,6-bis-(2-hydroxyethylamino)-toluene, 2,4-diaminophenoxyethanol, 1methoxy-2-amino-4-(2-hydroxyethylamino)-benzene, 2-methyl-4-chloro-5-aminophenol, 6-methyl- 1,2,3,4-tetrahydroquinoxaline, 3,4-methylenedioxyphenol, 3,4-methylenedioxyaniline, 2,6-dimethyl-3aminophenol, 3-amino-6-methoxy-2-methylaminophenol, 2-hydroxy-4-aminophenoxyethanol, 2methyl-5-(2-hydroxyethylamino)-phenol and 2,6-dihydroxy-3,4-dimethyl pyridine.

Although intensive colours with good fastness properties can be obtained with oxidation dyes, the colour is generally developed under the influence of oxidising agents, such as H202 for example, which in some cases can result in damage to the fibres. In addition, some oxidation dye precursors or ertain mixtures of oxidation dye precursors can occasionally have a sensitising effect in people with sitive skin. Although substantive dyes are applied under more moderate conditions, their dis dvantage is that, in many cases, the colours obtained have inadequate fastness properties.

C07867 2 DE-AS 28 30 497 discloses hair colorants which contain salicylaldehyde in combination with oxidation dye precursors, for example 2,5-diaminotoluene, 4-aminophenol or 2,4-diaminotoluene, but which can have a more or less high sensitising potential (in combination with the hydrogen peroxide additionally present). DE-AS 29 32 498 also discloses H 2 02-containing hair colorants which contain benzaldehydes, for example 2-hydroxy-3-methoxybenzaldehyde or 4-hydroxy-3methoxybenzaldehyde, in combination with oxidation dye precursors. US patents 5,034,014 and 5,199,954 describe hair colour formulation examples which contain p-dimethylaminobenzaldehyde or p-dimethylaminocinnamaldehyde, for example in combination with the sensitising pphenylenediamine.

US 4,391,603 relates to oxidant-free hair colorants which contain substituted benzaldehydes.

The hair colorants disclosed in this document are substantive colorants with which the shades, depths of colour and colour fastness values of hair colorants containing oxidation dyes precursors cannot be achieved.

The use of the aromatic aldehydes described in detail hereinafter for colouring keratincontaining fibres was not previously known.

The problem addressed by the present invention was to provide colorants for keratin fibres, more especially human hair, which would be at least equivalent in quality to conventional oxidation hair dyes in regard to depth of colour, grey coverage and fastness properties, but which would not necessarily have to contain oxidising agents, such as H 2 0 2 for example. In addition, the colorants according to the invention would have very little, if any, sensitising potential.

The present invention relates to the use of unsaturated aldehydes corresponding to the following tautomeric resonance formulae la and Ib: H R 3

It has surprisingly been found that the aldehydes corresponding to formulae la and Ib are eminently suitable for colouring keratin-containing fibres, even in the absence of oxidising agents.

They give colours with excellent brilliance and depth of colour and lead to a wide variety of shades. In principle, however, oxidising agents may be still be present.

In the context of the invention, keratin-containing fibres are understood to include wool, pelts, feathers and, in particular, human hair. In principle, however, the colorants according to the invention also be used to colour other natural fibres such as, for example, cotton, jute, sisal, linen or silk, .11odified natural fibres such as, for example, regenerated cellulose, nitro, alkyl or hydroxyalkyl or C07867 acetal cellulose and synthetic fibres such as, for example, polyamide, polyacrylonitrile, polyurethane and polyester fibres.

The unsaturated aldehydes corresponding to formulae la and Ib are preferably selected from the group consisting of glutaconaldehyde, 1-formyl-3-hydroxymethylene-1l-cyclohexene, 1-formyl-3hydroxymethylene-1-cycloheptene and 7-hydroxy-2,4,6-heptatrienal and their substituted derivatives and physiologically compatible salts thereof, more particularly the alkali metal and ammonium salts, the tetrabutyl ammonium salts and Na salts and mixtures thereof being particularly preferred.

The compounds corresponding to formula la and Ib are known from the literature or are commercially available.

The aldehydes corresponding to formulae la and Ib are present in the colorants in quantities of preferably 0.03 to 65mmol and more preferably 1 to 40mmol, based on 100Og of the colorant as a whole. A single compound with the formula la or lb or a mixture of several compounds may be used.

They may be used as substantive dyes or in the presence of compounds which intensify the colouring effect of the aldehydes used in accordance with the invention, such as oxidation dye precursors.

Colorants containing aldehydes of formula la or lb as their sole colouring component are preferably used for colours in the yellow and red range. Colours with even greater brilliance and further improved fastness properties, above all in the yellow, orange, brown and black range and in the red and blue range, are obtained when the aldehydes of formulae la and Ib are used together with compounds containing a primary or secondary amino group, for example aniline derivatives, with nitrogen-containing heterocyclic compounds, for example primary heteroaromatic amines, aromatic hydroxy compounds or CH-active compounds. These are, on the one hand, compounds which, on their own, have only a weak colouring effect on keratin-containing fibres and which only produce brilliant colours in conjunction with the aldehydes of formulae la and lb. However, they also include compounds which are already used as oxidation dye precursors.

The present invention also relates to a preparation for colouring keratin-containing fibres, more especially human hair, which contains A. at least one unsaturated aldehyde corresponding to formula la or Ib and B. at least one compound containing a primary or secondary amino group or hydroxy group selected from primary or secondary aliphatic or aromatic amines, nitrogen-containing heterocyclic compounds, amino acids, oligopeptides made up of 2 to 9 amino acids and aromatic hydroxy compounds and/or at least one CH-active compound.

The above-mentioned compounds of component B may be used in a quantity of 0.03 to and are preferably used in a quantity of 1 to 40mmol, based on 100Og of the colorant as a whole.

Several different aldehydes of formulae la and Ib may even be used together in the colorants.

Similarly, several different compounds of component B may also be used together. This embodiment also encompasses the use of substances which represent reaction products of unsaturated aldehydes corresponding to formula la and Ib with the compounds B.

Suitable compounds containing a primary or secondary amino group are, for example, primary matic amines, such as N,N-dimethyl-, N,N-diethyl-, N-(2-hydroxyethyl)-N-ethyl-, N,N-bis-(2- C07867 4 hydroxyethyl)-, N-(2-methoxyethyl)-, 2,5-dichloro-p-phenylenediamine, 2-chloro-pphenylenediamine, 2,5-dihydroxy-4-morpholinoaniline dihydrobromide, 4-aminophenol, 2aminomethyl-4-aminophenol, 2-hydroxymethyl-4-aminophenol, in-, p-phenylenediamine, mtoluylenediamine, 2,5-diaminotoluene, -phenol, -phenethol, 4-am ino-3-methyl phenol, 2-(2,5diaminophenyl)-ethanol, 2,4-diaminophenoxyethanol, 2-(2,5-diaminophenoxy)-ethanol, 4methylamino-, 3-amino-4-(2'-hydroxyethyloxy)-, 3,4-methylenediamino-, 3,4-methylenedioxyaniline, 3amino-2,4-dichloro-, 4-methylamino-, 2-methyl-5-amino-, 3-methyl-4,-amino-, 2-methyl-5-(2hydroxyethylamino)-, 6-methyl-3-amino-2-chloro-, 2-methyl-5-amino-4-chloro-, -2 hyd roxyethylamino)-4-methoxy-2-methyl phenol, 1 ,3-diamino-2,4-dimethoxybenzene, 4aminobenzoic acid, -phenylacetic acid, 3,5-diaminobenzoic acid, aminosalicylic acid, 3-amino-4-hydroxy-, 4-amino-3-hydroxybenzoic acid, 4aminobenzenesulfonic acid, 3-amino-4-hydroxybenzenesulfonic acid, 4-amino-3-hydroxynaphthalene- 1 -sulfonic acid, 6-amino-7-hydroxynaphthalene-2-sulfonic acid, 7-amino-4-hydroxynaphthalene-2sulfonic acid, 4-amino-5-hydroxynaphthalene-2,7-disulfonic acid, 3-amino-2-naphthoic acid, 3aminophthalic acid, 5-aminoisophthalic acid, 1 ,2,4-triaminobenzene, 1,2,4,5tetraaminobenzene, 2,4,5-triaminophenol, pentaaminobenzene, hexaaminobenzene, 2,4,6triaminoresorcinol, 4,5-diaminopyrocatechol, 4,6-diaminopyrogallol, 3,5-diamino-4hydroxypyrocatechol, aromatic anilines and phenols containing another aromatic radical corresponding to formula II: Rt (1I in which R 5 is a hydroxy group or an amino group which may be substituted by C14i alkyl, C1IA hydroxyalkyl, C1_4 alkoxy or C14 alkoxy-Cl-4-alkyl groups, R 6

With regard to the dyes suitable for use in the hair colouring and tinting formulations according to the invention, reference is also specifically made to Ch. Zviak's work The Science of Hair Care, Chapter 7 (pages 248-250; Substantive Dyes) and Chapter 8, pages 264-267; Oxidation Dye Precursors), published as Vol. 7 of the Series "Dermatology" (Editors: Ch. Culnan and H. Maibach), Marcel Dekker Inc., New York/Basel, 1986 and to the "Europiische Inventar der Kosmetik- Rohstoffe" published by the Europaische Gemeinschaft and available in diskette form from the Bundesverband Deutscher Industrie- und Handelsunternehmen fur Arzneimittel, Reformwaren und K6rperpflegemittel Mannheim, Germany.

The compounds of component B and optionally other oxidation dye precursors or the substantive dyes present, if any, do not have to be single compounds. Instead, the hair colorants according to the invention due to the processes used for producing the individual dyes may contain small quantities of other components providing they do not adversely affect the colouring result or have to be ruled out for other reasons, for example toxicological reasons.

The colorants according to the invention produce intensive colours even at physiologically compatible temperatures of <45°C. Accordingly, they are particularly suitable for colouring human hair. For application to human hair, the colorants are normally incorporated in a water-containing cosmetic carrier. Suitable water-containing cosmetic carriers are, for example, creams, emulsions, gels or even surfactant-containing foaming solutions, for example shampoos or other formulations suitable for application to the keratin-containing fibres. If necessary, the colorants may even be incorporated in water-free carriers.

The colorants according to the invention may also contain any of the known active substances, additives and auxiliaries typical of such formulations. In many cases, the colorants contain at least one surfactant, both anionic and zwitterionic, ampholytic, nonionic and cationic surfactants being suitable in principle. In many cases, however, it has been found to be of advantage to select the surfactants from anionic, zwitterionic or nonionic surfactants.

Suitable anionic surfactants for the preparations according to the invention are any anionic surface-active substances suitable for use on the human body. Such substances are characterised by a water-solubilising anionic group such as, for example, a carboxylate, sulfate, sulfonate or phosphate group and a lipophilic alkyl group containing around 10 to 22 carbon atoms. In addition, glycol or polyglycol ether groups, ester, ether, amide groups and hydroxyl groups may also be present in the molecule. The following are examples of suitable anionic surfactants in the form of the sodium, potassium and ammonium salts and the mono-, di- and trialkanolammonium salts containing 2 or 3 carbon atoms in the alkanol group: linear fatty acids containing 10 to 22 carbon atoms (soaps), ether carboxylic acids corresponding to the formula R-O-(CH 2 -CH20)x-CH2-COOH, in which R is a linear alkyl group containing 10 to 22 carbon atoms and x 0 or 1 to 16, C07867 acyl sarcosides containing 10 to 18 carbon atoms in the acyl group, acyl taurides containing 10 to 18 carbon atoms in the acyl group, acyl isethionates containing 10 to 18 carbon atoms in the acyl group, sulfosuccinic acid mono- and dialkyl esters containing 8 to 18 carbon atoms in the alkyl group and sulfosuccinic acid monoalkyl polyoxyethyl esters containing 8 to 18 carbon atoms in the alkyl group and 1 to 6 oxyethyl groups, linear alkane sulfonates containing 12 to 18 carbon atoms, linear a-olefin sulfonates containing 12 to 18 carbon atoms, a-sulfofatty acid methyl esters of fatty acids containing 12 to 18 carbon atoms, alkyl sulfates and alkyl polyglycol ether sulfates corresponding to the formula R-O(CH 2

Preferred anionic surfactants are alkyl sulfates, alkyl polyglycol ether sulfates and ether carboxylic acids containing 10 to 18 carbon atoms in the alkyl group and up to 12 glycol ether groups in the molecule and, in particular, salts of saturated and, more particularly, unsaturated C8- 2 2 carboxylic acids, such as oleic acid, stearic acid, isostearic acid and palmitic acid.

In the context of the invention, zwitterionic surfactants are surface-active compounds which contain at least one quaternary ammonium group and at least one or -SO3() group in the molecule. Particularly suitable zwitterionic surfactants are the so-called betaines, such as N-alkyl- N,N-dimethyl ammonium glycinates, for example cocoalkyl dimethyl ammonium glycinate, Nacylaminopropyl-N,N-dimethyl ammonium glycinates, for example cocoacylaminopropyl dimethyl ammonium glycinate, and 2-alkyl-3-carboxymethyl-3-hydroxyethyl imidazolines containing 8 to 18 carbon atoms in the alkyl or acyl group and cocoacylaminoethyl hydroxyethyl carboxymethyl glycinate.

A preferred zwitterionic surfactant is the fatty acid amide derivative known by the CTFA name of Cocamidopropyl Betaine.

Ampholytic surfactants are surface-active compounds which, in addition to a C8.18 alkyl or acyl group, contain at least one free amino group and at least one -COOH or -SO 3 H group in the molecule and which are capable of forming inner salts. Examples of suitable ampholytic surfactants are N-alkyl glycines, N-alkyl propionic acids, N-alkyl aminobutyric acids, N-alkyl iminodipropionic acids, Nhydroxyethyl-N-alkyl amidopropyl glycines, N-alkyl taurines, N-alkyl sarcosines, 2-alkyl aminopropionic acids and alkyl aminoacetic acids containing around 8 to 18 carbon atoms in the alkyl C07867 9 group. Particularly preferred ampholytic surfactants are N-cocoalkyl aminopropionate, cocoacyl aminoethyl aminopropionate and C12-18 acyl sarcosine.

Nonionic surfactants contain, for example, a polyol group, a polyalkylene glycol ether group or a combination of polyol and polyglycol ether groups as the hydrophilic group. Examples of such compounds are products of the addition of 2 to 30 moles of ethylene oxide and/or 0 to 5 moles of propylene oxide to linear fatty alcohols containing 8 to 22 carbon atoms, to fatty acids containing 12 to 22 carbon atoms and to alkylphenols containing 8 to 15 carbon atoms in the alkyl group, C12-22 fatty acid monoesters and diesters of products of the addition of 1 to 30 moles of ethylene oxide to glycerol, C8.22 alkyl mono- and oligoglycosides and ethoxylated analogues thereof, products of the addition of 5 to 60 moles of ethylene oxide to castor oil and hydrogenated castor oil, products of the addition of ethylene oxide to sorbitan fatty acid esters, products of the addition of ethylene oxide to fatty acid alkanolamides.

Examples of cationic surfactants suitable for use in the hair treatment formulations according to the invention are, in particular, quaternary ammonium compounds. Preferred quaternary ammonium compounds are ammonium halides, such as alkyl trimethyl ammonium chlorides, dialkyl dimethyl ammonium chlorides and trialkyl methyl ammonium chlorides, for example cetyl trimethyl ammonium chloride, stearyl trimethyl ammonium chloride, distearyl dimethyl ammonium chloride, lauryl dimethyl ammonium chloride, lauryl dimethyl benzyl ammonium chloride and tricetyl methyl ammonium chloride. Other cationic surfactants suitable for use in accordance with the invention are the quaternised protein hydrolysates.

Also suitable for use in accordance with the invention are cationic silicone oils such as, for example, the commercially available products Q2-7224 (manufacturer: Dow Corning; a stabilised trimethyl silyl amodimethicone), Dow Corning 929 Emulsion (containing a hydroxylamino-modified silicone which is also known as Amodimethicone), SM-2059 (manufacturer: General Electric), SLM- 55067 (manufacturer: Wacker) and Abil®-Quat 3270 and 3272 (manufacturer: Th. Goldschmidt; diquaternary polydimethyl siloxanes, Alkyl amidoamines, particularly fatty acid amidoamines, such as the stearyl amidopropyl dimethyl amine obtainable as Tego Amid@S 18, are distinguished not only by their favourable conditioning effect, but also and in particular by their ready biodegradability.

Quaternary ester compounds, so-called "esterquats", such as the dialkyl ammonium methosulfates and methyl hydroxyalkyl dialkoyloxyalkyl ammonium methosulfates marketed under the trade name of Stepantex®, are also readily biodegradable.

One example of a quaternary sugar derivative suitable for use as a cationic surfactant is the commercially available product Glucquat®100 (CTFA name: Lauryl Methyl Gluceth-10 Hydroxypropyl Dimonium Chloride).

RA The compounds containing alkyl groups used as surfactants may be single compounds. In eneral, however, these compounds are produced from native vegetable or animal raw materials so C07867 that mixtures with different alkyl chain lengths dependent upon the particular raw material are obtained.

The surfactants representing addition products of ethylene and/or propylene oxide with fatty alcohols or derivatives of these addition products may be both products with a "normal" homologue distribution and products with a narrow homologue distribution. Products with a "normal" homologue distribution are mixtures of homologues which are obtained in the reaction of fatty alcohol and alkylene oxide using alkali metals, alkali metal hydroxides or alkali metal alcoholates as catalysts. By contrast, narrow homologue distributions are obtained when, for example, hydrotalcites, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides or alcoholates are used as catalysts. The use of products with a narrow homologue distribution can be of advantage.

Other active substances, auxiliaries and additives are, for example, nonionic polymers such as, for example, vinyl pyrrolidone/vinyl acrylate copolymers, polyvinyl pyrrolidone and vinyl pyrrolidone/vinyl acetate copolymers and polysiloxanes, cationic polymers, such as quaternised cellulose ethers, polysiloxanes containing quaternary groups, dimethyl diallyl ammonium chloride polymers, acrylamide/dimethyl diallyl ammonium chloride copolymers, dimethyl aminoethyl methacrylate/vinyl pyrrolidone copolymers quaternised with diethyl sulfate, vinyl pyrrolidone/imidazolinium methochloride copolymers and quaternised polyvinyl alcohol, zwitterionic and amphoteric polymers such as, for example, acrylamidopropyl/trimethyl ammonium chloride/acrylate copolymers and octyl acrylamide/methyl methacrylate/tert.butyl aminoethyl methacrylate/2-hydroxypropyl methacrylate copolymers, anionic polymers such as, for example, polyacrylic acids, crosslinked polyacrylic acids, vinyl acetate/crotonic acid copolymers, vinyl pyrrolidone/vinyl acrylate copolymers, vinyl acetate/butyl maleate/ isobornyl acrylate copolymers, methyl vinyl ether/maleic anhydride copolymers and acrylic acid/ethyl acrylate/N-tert.butyl acrylamide terpolymers, thickeners, such as agar agar, guar gum, alginates, xanthan gum, gum arabic, karaya gum, carob bean flour, linseed gums, dextrans, cellulose derivatives, for example methyl cellulose, hydroxyalkyl cellulose and carboxymethyl cellulose, starch fractions and derivatives, such as amylose, amylopectin and dextrins, clays such as, for example, bentonite or fully synthetic hydrocolloids such as, for example, polyvinyl alcohol, structurants, such as glucose and maleic acid, hair-conditioning compounds, such as phospholipids, for example soy lecithin, egg lecithin and kephalins, and also silicone oils, protein hydrolysates, more particularly elastin, collagen, keratin, milk protein, soy protein and wheat protein hydrolysates, condensation products thereof with fatty acids and quaternised protein hydrolysates, perfume oils, dimethyl isosorbide and cyclodextrins, solubilisers, such as ethanol, isopropanol, ethylene glycol, propylene glycol, glycerol and "ki iethylene glycol, uj) antidandruff agents, such as Piroctone Olamine and Zinc Omadine, C07867 11 other substances for adjusting the pH value, active substances, such as panthenol, pantothenic acid, allantoin, pyrrolidone carboxylic acids and salts thereof, plant extracts and vitamins, cholesterol, UV filters, consistency factors, such as sugar esters, polyol esters or polyol alkyl ethers, fats and waxes, such as spermaceti, beeswax, montan wax, paraffins, fatty alcohols and fatty acid esters, fatty acid alkanolamides, complexing agents, such as EDTA, NTA and phosphonic acids, swelling and penetration agents, such as glycerol, propylene glycol monoethyl ether, carbonates, hydrogen carbonates, guanidines, ureas and primary, secondary and tertiary phosphates, imidazoles, tannins, pyrrole, opacifiers, such as latex, pearlescers, such as ethylene glycol mono- and distearate, propellents, such as propane/butane mixtures, N 2 0, dimethyl ether, CO2 and air and antioxidants.

To produce the colorants according to the invention, the constituents of the watercontaining carrier are used in the usual quantities for this purpose. For example, emulsifiers are used in concentrations of 0.5 to 30wt% while thickeners are used in concentrations of 0.1 to 25wt%, based on the colorant as a whole.

It can be of advantage to the colouring result to add ammonium or metal salts to the colorants.

Suitable metal salts are, for example, formates, carbonates, halides, sulfates, butyrates, valerates, caproates, acetates, lactates, glycolates, tartrates, citrates, gluconates, propionates, phosphates and phosphonates of alkaline earth metals, such as potassium, sodium or lithium, alkaline earth metals, such as magnesium, calcium, strontium or barium, or of aluminium, manganese, iron, cobalt, copper or zinc, sodium acetate, lithium bromide, calcium bromide, calcium gluconate, zinc chloride, zinc sulfate, magnesium chloride, magnesium sulfate, ammonium carbonate, chloride and acetate being preferred. These salts are preferably present in a quantity of 0.03 to 65mmol and more preferably in a quantity of 1 to 40mmol, based on 100g of the colorant as a whole.

The pH value of the ready-to-use colouring preparations is normally in the range from 2 to 11 and preferably in the range from 5 to 9.

In order to colour the keratin-containing fibres, more especially human hair, the colorants are generally applied to the hair in the form of the water-containing cosmetic carrier in a quantity of 100g, left thereon for about 30 minutes and then rinsed out or washed out with a commercially available shampoo.

The aldehydes corresponding to formulae la and Ib and the compounds of component B may either be applied to the hair simultaneously or even successively, in which case it does not matter which of the two components is applied first. The ammonium or metal salts optionally present may be iadded to the first component or to the second component. A time of up to 30 minutes can be allowed C07867 12 to pass between application of the first component and application of the second component. The fibres may even be pretreated with the salt solution.

The aldehydes corresponding to formulae la and lb and the compounds of component B may be stored either separately or together either in the form of a liquid or paste-like preparation (aqueous or water-free) or as a dry powder. If the components are stored together in a liquid preparation, the preparation in question should be substantially free from water to reduce any risk of the components reacting. Where the reactive components are stored separately, they are mixed thoroughly together only shortly before application. Where the components are stored as a dry powder, a defined quantity of warm water (50 to 80 0 C) is normally added and a homogeneous mixture prepared before application.

Examples Preparation of a colouring solution A suspension of 10mmol of an aldehyde corresponding to formula la or Ib, 10mmol of a reactant, 10mmol of sodium acetate and 1 drop of a 20% fatty alkyl ether sulfate solution in 100mL of water was prepared. The suspension was briefly heated to around 80 0 C and filtered after cooling, after which the pH value was adjusted to 6.

One tress of 90% grey, non-pretreated human hair was placed in this colouring solution for minutes at 30 0 C. The coloured tress was then rinsed for 30 seconds with luke-warm water, dried in a stream of warm air (30-40°C) and then combed. The colours were visually evaluated in daylight.

The particular shades and depths of colour are shown in Table 1 below.

The depth of colour was evaluated on the following scale: very faint, if any, colour weak intensity medium intensity medium to strong intensity strong intensity strong to very strong intensity very strong intensity Table 1 Colouring with 2-chloro-1-formyl-3-hydroxymethylene cyclohexene Component B Shade Depth of colour Yellow x H 2
