Definitions

• This invention relates to compositions for the dyeing or tinting of hair and to methods of use thereof.
• Examples of such products are 2-hydroxy-1-4-naphthoquinone and the products desulting from the application of the dyeing process described in French Patent No. 826,046, which process makes it possible to obtain the transformation of trihydroxl derivatives into quinone products on the fibre. In all such cases it is only possible to obtain shades from bloude to titian red on live hair with the aid of these products. Deeper shades can only be obtained by means of these products if they are admixed with products already known for dyeing hair, such as phenylenediamines and aminophenols, which are toxic, or by the addition of metallic salts. This latter process presents the disadvantage of not permitting subsequent capillary treatment, such as permanent waving or bleaching.
• the present invention provides a composition for the treatment of hair for the purpose of dyeing or tinting which comprises a compound represented by the general formula:
• X represents a hydrogen or halogen atom, or an alkyl, alkoxy or hydroxy-alkyl group free from solubilising groups.
• a base or a salt of a base of the group comprising ammonia and primary it is preferred to add to said composition, immediately before carrying out the dyeing of the hair, a base or a salt of a base of the group comprising ammonia and primary,
• I R represents a bivalent aliphatic residue, which may or may not contain an alcoholic function
• Y represents a hydrogen atom or a carboxyl group
• the proportion of reducing agent incorporated in the composition according to the invention permits the speed of development of the shade of dyeing to be regulated, such shade being determined at the time by the nature and relative proportions of the products entering into the final dye obtained after the addition of the base or bases, or a salt of these bases, to this composition at the moment it is used.
• the mercaptan not only performs the known function of a reducing agent which assists in the maintenance of the original qualities of the trihydroxyl substance which is used, but it also exerts a chemical or physiochemical action which facilitates the formation of the colouring on the hair; however, the invention is not to be regarded as limited by this theory.
• the invention does not include the addition of metallic salts for any of the shades obtained, it enables the superimposition of dyes and capillary treatments, such as bleaches with persalts and permanent waves to be performed without danger of changing or destroying the hair. This constitutes an essential difference both as regards the process indicated in French Patent No. 826,046 and the publication of Stoves and Burton.
• the hair dyed in accordance with this novel process is characterised in all cases by a lustre not hitherto obtained by means of ordinary dyes, and as these products are not toxic, they do not necessitate any special precautions being taken, such as a test lock, which it is essential to carry out with dyes having oxidation colouring agents.
• a composition in accordance with the invention is preferably provided in the form of a cream which facilitates the application to the live head of hair, by using in known manner a thickening agent and an agent having dispersive and wetting properties in order to facilitate the penetration of the dye into the hair.
• Example I 3 parts of 2-4-5-trihydroxytoluene and 0.4 part of thioglycollic acid are added to the cream obtained by emulsifying 20 parts glycol stearate in 77 parts water by means of a product having dispersive and wetting properties (such as sulphonated lauryl alcohol). At the moment of use, 10 parts of a 20% solution of ammonia are added. The mixture obtained is applied to the hair and left for about half-an-hour at 3540C. The hair is then rinsed, washed and dried.
• a product having dispersive and wetting properties such as sulphonated lauryl alcohol
• the hairs are dyed black, the dye being particularly fast to washing, rubbing and light.
• Example 11 3 parts of 2-4-5-trihydroxytoluene and 0.4 part of thioglycerol are added to a cream obtained by emulsifying 20 parts glycerol stearate in 77 parts water by means of a product having dispersive and wetting properties (such as sulphonated lauryl alcohol). At the moment of use, 2 parts of monoethanolamine are added, the mixture obtained is applied to the hair and left for about half-an-hour at 35-40 C. The hair is rinsed, washed and dried.
• a product having dispersive and wetting properties such as sulphonated lauryl alcohol
• the hairs are dyed a deep chestnut brown, the dye being particularly fast to washing, rubbing and light.
• Example Ill 3 parts of 2-4-5-trihydroxytoluene and 0.4 part of thicglycollic acid are added to a cream obtained by emulsifying 20 parts of glycol stearate in 77 parts water by means of a product having dispersive and Wetting properties (such as sulphonated lauryl alcohol). At the moment of use, parts of triammonium phosphate are added. The mixture obtained is applied to the hair, left for about halfan-hour at 35-40 C., and the hair is rinsed, washed and dried.
• a product having dispersive and Wetting properties such as sulphonated lauryl alcohol
• the hair is dyed a deep chestnut brown with a violet glint, the dye being particularly fast to washing, rubbing and light.
• Example IV 3 parts of 2-4-S-trihydroxytoluene and 0.4 part of thioglycerol are added to a cream obtained by emulsifying parts of glycerol stearate in 77 parts water by means of a product having dispersing and Wetting properties (such as sulphonated lauryl alcohol).
• a product having dispersing and Wetting properties such as sulphonated lauryl alcohol.
• 3 parts of triethanolamine are added and the mixture ob tained is applied to the hair. It is left for about half-anhour at 35-40" C. and the hair is then rinsed, washed and dried.
• the hair is dyed auburn, the dye being particularly fast to washing, rubbing and light.
• Example V 3 parts of 2-4-5-trihydroxytoluene and 0.4 part of thiolactic acid are added to a cream obtained by emulsifying 20 parts of glycol stearate in 77 parts water, by means of a product having dispersing and wetting properties (such as sulphonated lauryl alcohol). At the moment of use, 2.5 parts of morpholine are added. The mixture obtained is applied to the hair, and left for about half-an-hour at 35-40 C. The hair is then rinsed, washed and dried.
• a product having dispersing and wetting properties such as sulphonated lauryl alcohol
• the hairs are dyed a shade from golden blonde to light auburn.
• a hair-dyeing composition comprising an intimate mixture of a compound free from any solubilizing group and represented by the formula (WP-X O H wherein X is a monovalent radical selected from the class consisting of hydrogen, halogens, alkyl, alkoxy and bydroxyalkyl groups, a me rcaptan reducing agent represented by the formula wherein R is a bivalent aliphatic residue and Y is selected from the class consisting of hydrogen and a carboxyl group, in combination with a base added immediately prior to the application of said composition to the hair, said base being selected from the class consisting of ammonia, an aliphatic amine and a cycloaliphatic amine.
• WP-X O H wherein X is a monovalent radical selected from the class consisting of hydrogen, halogens, alkyl, alkoxy and bydroxyalkyl groups, a me rcaptan reducing agent represented by the formula wherein R is a bivalent aliphatic
