9 Claims, N0 Drawings KERATINIC FIBRESOXIDATION DYEING COMPOSITIONS CONTAINING A CABONATE OF AN ALKALI METAL AMINO ACID This is a continuation of application Ser. No. 204,379, filed Dec. 2, 1971, now abandoned.

FIELD OF THE INVENTION The present invention relates to novel dyeing compositions for dyeing keratinic fibres, notably human hair, which are free of the inconveniences characterizing conventional dyeing compositions.

BACKGROUND OF THE INVENTION To dye keratinic fibres and more particularly human hair, chemical intermediates hereinafter referred to as Precursors of oxidation dyestuffs are usually employed and these intermediates, through an oxidation process consisting in utilizing a low oxidizing agent in an alkaline medium, lead to the formation of pigments distributed through the keratinic fibre to yield variegated hues depending on the nature and proportions of said precursors used in admixture and of which the total percentage in the dyeing composition, not including the oxidizer added just before the actual use, varies as a rule from about 0.2 to about 15% by weight.

The main precursors of oxidation dyestuffs generally employed consist essentially of aromatic diamines, such as p-phenylene diamine, p-toluylene diamine, mtoluylene diamine, and their substituted derivatives such as nitro p-phenylene diamine; the amino-phenols and their derivatives such as 2,4-diamine anisol sulfate and p-N-methylamino phenol sulfate; diphenols such as resorcinol and hydroquinone; etc..

The most widely used weak oxidizing agents are hydrogen peroxide in aqueous solution ranging as a rule from 3 to H 0 by weight, urea peroxide, and sodium perborate.

The alkaline medium is obtained by adding ammonia to the above-listed precursors for the triple purpose of preparing the hair to a maximum receptivity by swelling it and facilitating the penetration of the other components of the dyeing composition, creating favorable pH conditions for performing the oxidation and making the oxygenated water unstable.

The presence of ammonia in the dyeing composition, in amounts as high at 12 to 15% by weight and in the form of an aqueous solution at 22 Baume is a constant source of inconveniences and discomfort both for the user and for the person to which the product is applied. In fact, the suffocating odor of ammonia appears unavoidably when the other component elements of the dyeing composition are mixed up with the oxidizer just before the actual use, then during the application of the product and even during the time necessary for allowing this product to exert its activity.

On the other hand, when treating relatively sensitive scalps, ammonia produces in all cases reactions ranging from slight pricking to the impression of intense burns. This last effect is almost automatic whenever a dyeing operation is performed after a bleaching operation having already rendered the scalp more sensitive.

These inconveniences are extremely noxious and make the application rather unpleasant.

Moreover, since ammonia tends to become diffused through a great number of plastic materials and elastomers, these substances cannot be used for containing and storing known dyeing compositions for keratinic fibres, irrespective of the method employed. More particularly, it is not possible to pack these dyeing compositions in aerosol containers of any type known per se which comprise twin valves and twin compartments, i.e. one compartment consisting of a flexible bag or bladder or plastic or elastomeric material, enclosed in the other compartment, generally of suitable metal, which may advantageously contain the oxidizing agent for these compositions, which is adapted to be mixed up with the actual composition when using the product; in fact, it is well known that the ammonia diffused through the walls of said bag or bladder would decompose the oxygen peroxide constituting the most usual oxidizing agent, so that large amounts of oxygen would be released and cause the internal pressure of the container to rise rapidly until an explosion occurs while rendering the product gradually inefficient, in any case, due to the decomposition of the oxygenated water which had to be put in contact with the other components and was normally expected to become effective only at the actual time of use of the product, not before.

In order to obtain dyeing compositions free of any aggressiveness and adapted to be stored and packed in the manner set forth hereinabove, the Applicants provide novel formulae for products of the type disclosed hereinabove which are free, or contain only very small amounts of ammonia.

By eliminating or at least reducing to a substantial degree the ammonia content, the Applicants succeeded in developing products free of any unpleasant feelings as described hereinabove, of any problem concerning their application from the point'of view of their aggressiveness with respect to the scalp. Another highly appreciable advantage of the products of this invention is that the aesthetic appearance of the hair treated therewith is better preserved and even enhanced. Whereas in the presence of ammonia the hair or other keratinic fibre has a rather lusterless and harsh appearance. as if it were dried up, when using ammonia-containing formulae, on the contrary, the fibre appears as brilliant and smooth, is disentangled much more easily, and has finally a much more attractive and aesthetic appearance.

SUMMARY OF THE INVENTION Since the alkaline medium is definitely necessary for accomplishing the oxidation operation, the present invention provides dyeing compositions containing precursors of oxidation dyestuffs, alkalinizing agents, and a weak oxidizing agent to be added at the time of the actual application, said compositions being characterized in that they contain as an alkalinizing agent the carbonate of an amino acid alkali metal or ammonium salt, as an at least partial substitute for ammonia. Said carbonate is a non-volatile and non-aggressive alkaline agent.

Preferably, the amino acid consists of glycine or glycocoll, or amino-acetic acid, but it may also consist of lysine, methionine, tyrosine, glutamic acid, leucine, valine, alanine. These amino acids may be used in the racemic form or in the form of their optical isomers. The alkaline salt may be the sodium salt, the potassium salt or the lithium salt.

This carbonate of amino acid alkali metal or ammonium salt may be associated with organic bases such as morpholine, monoethanolamine, diethanolamine, triethanolamine, etc.

The dyeing compositions according to this invention may be used in the form of aqueous solutions of gelling liquids (before use, converted into gels by the addition of the oxidizing agent) containing non-ionic or anionic surface-active products, and aqueous emulsions generally of cream consistency.

The proportion of the novel alkalinizing agent in these compounds is advantageously from 1 to 10% by weight and the proportion of the possible organic bases ranges preferably from I to 7% by weight, these proportions being calculated on the weight of the compound, not including the oxidizing agent.

By using the carbonate of an amino acid alkali metal or ammonium salt possibly associated with an organic base and free of ammonia as an alkalinizing agent, the Applicants observed that it was thus possible to obtain formulae giving very good results for dyeing applications made on hair having a color lighter than, or of same hue as, the desired shade, and on previously bleached hair. These are ideal application cases; the comfort of the person to whom the treatment is applied is complete; there are neither unpleasant odor nor any aggressiveness to the scalp; the shades thus obtained are extremely aesthetic; the hair is brilliant, smooth and easily disentangled. The advantages are identical with those obtained in the case of keratinic fibres in general.

On the other hand, the above examples do not yield sufficient results when hues lighter than the hair color are desired, or more generally lighter than the color of the support to which the dyeing composition is applied. in fact, in these specific cases and according to the well-known methode the presence of oxygenated water and ammonia is attended, concurrently to the obtaining of the artificial shade, by a lighter color or clearing of the natural hair shade. This result is obtained in general by the use of high ammonia concentrations in the dyeing composition, and thus so-called clearing dyeing products are obtained. This is due to the alteration of the natural pigments of the hair on account of the action exerted by oxygenated water in a medium having a relatively high ammonia content.

Now, since this shading off reaction is superposed to that causing the formation of artificial pigments, it is possible to obtain hues very considerably lighter than the initial natural shade, without inasmuch producing a real bleaching action.

This technique-scarcely approved by the majority of professional hair-dessers due to the strong proportions of ammonia required for its application and therefore to the resulting inconveniences already discussed hereinaboveis nevertheless becoming increasingly popular on account of the relative facility with which it can be carried out, the time spared and the economy obtained for the user due to the elimination of one operation (i.e. bleaching) which is always relatively expensive.

Now, as far as hair clearing is concerned, the formulae given in the above Examples do not perform sufficiently to deserve the term ofclearing dyeing compositions. To obtain an appreciable and satisfactory clearing action the operation must be carried out at a higher pH value than that obtained with the carbonate of an amino acid alkali metal or ammonium salt, and therefore formulae containing complementary ammonia in addition to the organic bases possibly included therein, had to be developed.

in these additional formulae ammonia is present in reduced proportions ranging from 0 to 6% by weight in the form of an aqueous solution at 22 Baume in relation to the weight of the composition, not including the oxidizing agent.

it was found that the presence of the carbonate of an amino acid alkali metal or ammonium salt made it possible to obtain hair clearing results comparable to those usually obtained by using ammonia proportions corresponding to two or three times those contemplated in this invention. It is thus possible to take advantage of the attractive technique consisting in applying a color clearing composition with an ammonia proportion definitely inferior to the conventional proportions, thus reducing to a very appreciable extent the inconveniences of ammonia which are described hereinabove.

Typical formulae of clearing dyeing compositions in the form of emulsions or creams comprising limited amounts of ammonia, due to the presence of carbonate of sodium glycinate with or without an organic base such as monoethanolamine, diethanolamine, triethanolamine, morpholine and the like, will now be given in detail:

For preparing these products on a commercial scale, it is deemed more advantageous and economical to prepare the carbonate of an amino acid alkali metal of ammonium salt extemporaneously during the manufacturing process.

To this end, it is only necessary to dissolve together in demineralized water the equivalent of one molecule of alkali metal carbonate or ammonium carbonate and two molecules of amino acid. These proportions actually permit of obtaining, for example, carbonate of sodium glycinate:

3- [NH3 CH COONA] In addition, this method permits of taking advantage of the relative proportions of alkali metal carbonate or ammonium carbonate in relation to the amino-acid. Thus, it is possible, by using certain formulae, to operate in the presence of an excess of alkali metal carbonate such as sodium carbonate, and, thus improve the performances in the case of-moderately receptive fibres or hair.

A few examples of these formulae are given hereinafter in the form of emulsions or creams:
