Description
The invention relates to a composition for the oxidation dyeing of keratin fibres, and in particular of human keratin fibres such as the hair, this composition comprising, in a medium which is suitable for dyeing, at least one oxidation base, sarcosine oxidase, and at least one donor for the said sarcosine oxidase, as well as to the dyeing process using this composition.
It is known to dye keratin fibres, and in particular human hair, with dye compositions containing oxidation dye precursors, in particular ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic bases which are generally referred to as oxidation bases. Oxidation dye precursors, or oxidation bases, are colourless or weakly coloured compounds which, when combined with oxidizing products, can give rise to coloured compounds and dyes by a process of oxidative condensation.
It is also known that the shades obtained with these oxidation bases can be varied by combining them with couplers or colour modifiers, the latter being chosen in particular from aromatic meta-diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds.
The variety of compounds used as regards the oxidation bases and the couplers allows a wide range of colours to be obtained.
The so-called "permanent" coloration obtained by means of these oxidation dyes must moreover satisfy a certain number of requirements. Thus it must have no toxicological drawbacks, it must be able to give shades of the desired intensity and it must be able to withstand external agents (light, bad weather, washing, permanent-waving, perspiration, rubbing).
The dyes must also be able to cover white hair and, lastly, they must be as unselective as possible, i.e. they must give the smallest possible colour differences along the same length of keratin fibre, which may in fact be differently sensitized (i.e. damaged) between its tip and its root.
The oxidation dyeing of keratin fibres is generally carried out in alkaline medium, in the presence of hydrogen peroxide. However, the use of alkaline media in the presence of hydrogen peroxide has the drawback of causing appreciable degradation of the fibres, as well as considerable bleaching of the keratin fibres, which is not always desirable.
The oxidation dyeing of keratin fibres can also be carried out using oxidizing systems other than hydrogen peroxide, such as enzymatic systems. Thus, it has already been proposed to dye keratin fibres, in particular in patent application EP-A-0,310,675, with compositions comprising an oxidation dye precursor of benzenic type in combination with enzymes such as pyranose oxidase, glucose oxidase or uricase, in the presence of a donor for the said enzymes. Although being used under conditions which do not result in degradation of the keratin fibres which is comparable to that caused by the dyes used in the presence of hydrogen peroxide, these dyeing processes are not entirely satisfactory, in particular as regards the strength of the colorations obtained.
Now, the Applicant has just discovered that it is possible to obtain novel dyes, capable of leading to colorations that are stronger than those of the prior art using an enzymatic system, by combining at least one oxidation base, at least one enzyme of sarcosine oxidase type, and at least one donor for the said enzyme.
This discovery forms the basis of the present invention.
A first subject of the invention is thus a ready-to-use composition for the oxidation dyeing of keratin fibres, and in particular of human keratin fibres such as the hair, characterized in that it comprises, in a medium which is suitable for dyeing:
at least one oxidation base,
sarcosine oxidase,
and at least one donor for the said sarcosine oxidase.
The dye composition in accordance with the invention makes it possible to obtain colorations that are stronger than those obtained with the compositions of the prior art using an enzymatic oxidizing system, such as, for example, the uric acid/uricase oxidizing system.
Furthermore, the colorations obtained with the dye composition in accordance with the invention are relatively unselective and show good resistance to the various attacking factors to which the hair may be subjected (light, bad weather, washing, permanent-waving, etc.).
A subject of the invention is also a process for the oxidation dyeing of keratin fibres using this ready-to-use dye composition.
The nature of the oxidation base(s) used in the ready-to-use dye composition is not a critical factor. They can be chosen, in particular, from para-phenylenediamines, double bases, para-aminophenols, ortho-aminophenols and heterocyclic oxidation bases.

Needless to say, a person skilled in the art will take care to select this or these optional complementary compound(s) such that the advantageous properties intrinsically associated with the ready-to-use dye composition in accordance with the invention are not, or are not substantially, adversely affected by the addition or additions envisaged.
The ready-to-use dye composition in accordance with the invention can be in various forms, such as in the form of liquids, creams or gels, which are optionally pressurized, or in any other form which is suitable for dyeing keratin fibres, and in particular human hair. In the case of a ready-to-use dye composition, the oxidation dyes(s) and the sarcosine oxidase are present within the same ready-to-use composition, and consequently the said composition must be free of oxygen gas, so as to avoid any premature oxidation of the oxidation dye(s).
A subject of the invention is also a process for dyeing keratin fibres, and in particular human keratin fibres such as the hair, using the ready-to-use dye composition as defined above.
According to this process, at least one ready-to-use dye composition as defined above is applied to the fibres, for a period which is sufficient to develop the desired coloration, after which the fibres are rinsed, optionally washed with shampoo, rinsed again and dried.
The time required to develop the coloration on the keratin fibres is generally between 3 and 60 minutes and even more precisely between 5 and 40 minutes.
According to one specific embodiment of the invention, the process includes a first step which consists in separately storing, on the one hand, a composition (A) comprising, in a medium which is suitable for dyeing, at least one oxidation base and, on the other hand, a composition (B) containing, in a medium which is suitable for dyeing, sarcosine oxidase in the presence of at least one donor of the said sarcosine oxidase, and then in mixing them together at the time of use, before applying this mixture to the keratin fibres.
Another subject of the invention is a multi-compartment dyeing device or "kit" or any other multi-compartment packaging system, a first compartment of which contains composition (A) as defined above and a second compartment of which contains composition (B) as defined above. These devices can be equipped with means for applying the desired mixture to the hair, such as the devices described in patent FR-2,586,913 in the name of the Applicant.
The examples which follow are intended to illustrate the invention without, however, limiting its scope.
EXAMPLES
Comparative Examples 1 and 2
The ready-to-use dye compositions below were prepared (contents in grams):
It is important to note that each of the ready-to-use dye compositions described above contain the same amount of enzyme, i.e. 20,000 I.U.
Each of the ready-to-use dye compositions described above was applied to locks of permed grey hair containing 90% white hairs, for 30 minutes. The hair was then rinsed, washed with a standard shampoo and then dried.
The colour of the locks was then evaluated, before and after the dyeing operation, in the Munsell system using a Minolta CM 2002 calorimeter so as to determine the strength of the colorations obtained with each of the compositions described above.
The difference between the colour of a lock before dyeing and the colour of the lock after dyeing was calculated by applying the Nickerson formula
as described, for example, in "Couleur, Industrie et Technique": pages 14-17; vol No. 5; 1978.
In this formula, .DELTA.E represents the colour difference between two locks, .DELTA.H, .DELTA.V and .DELTA.C represent the variation in absolute value of the parameters H, V and C, and Co represents the purity of the lock relative to which it is desired to evaluate the colour difference.
The strength of the coloration (.DELTA.E) is proportionately greater the higher the figure indicated.
The results are given in Table I below:
These results show that the ready-to-use dye composition of Example 1 in accordance with the invention, i.e. the composition containing, as oxidizing system, the combination of sarcosine oxidase and sarcosine, leads to a coloration which is stronger than that obtained with the ready-to-use dye composition of Example 2 not forming part of the invention since it contains, as oxidizing system, the combination of uricase and uric acid. The use of the uricase/uric acid oxidizing system is described in particular in patent application EP-A-0,310,675.
