Description

Technical field

BACKGROUND OF THE INVENTION The present invention relates to an oxidizing agent for the treatment of keratin fibers, comprising at least one oxidizeductase enzyme with two electrons in the presence of at least one donor for said enzyme and at least one cationic or amphoteric substantive polymer, as well as its use for dyeing, permanently modeling or bleaching keratin fibers especially human hair.

BACKGROUND OF THE INVENTION

It is known to dye keratin fibers, and in particular human hair, with dyeing compositions containing oxidative dye precursors, in particular p-phenylenediamines, o- or p-aminophenols and heterocyclic bases, which are commonly referred to as oxidation bases. Oxidative dye precursors or oxidation bases are weakly colored compounds which, in combination with oxidation products, can increase the color of the compounds and dyes by oxidative condensation.

It is also known that the shades obtained by these oxidation bases can be varied by combining them with coupling agents or modifiers, the modifiers being selected in particular from aromatic m-diamines, n-aminophenols and certain heterocyclic compounds.

The variety of compounds used as oxidizing bases and as coupling agents allows a wide range of colors to be obtained.

In addition, the so-called "permanent" coloration achieved by the use of these oxidative dyes must satisfy some other requirements. It must not have any toxic disadvantages, it must be able to deliver shades of the desired intensity and must be resistant to external influences (light, bad weather, washing, permanent waving, sweating, wiping).

The dyes must also be able to include white hair and, finally, be as selective as possible, in other words they must provide the smallest possible color differences along the length of keratin fibers, which may in fact be of different sensitivity (eg damaged) between root and tail.

The oxidative dyeing of keratin fibers is usually carried out in an alkaline environment in the presence of hydrogen peroxide. However, the use of an alkaline medium in the presence of hydrogen peroxide has the significant disadvantage of considerable damage to the fibers as well as a considerable discoloration of keratin fibers, which is not always desirable.

Oxidative dyeing of keratin fibers can also be performed using oxidation systems other than hydrogen peroxide, such as enzyme systems. Thus, it has already been proposed to dye keratin fibers, particularly in patent application EP-A-0 310 675 with compositions comprising oxidative dye precursors in combination with enzymes such as pyranose oxidase, glucose oxidase or uricase, in the presence of a donor for said enzymes. Although used under conditions which do not result in degradation of keratin fibers comparable to the degradation caused by the dye used in the presence of hydrogen peroxide, these color formulations result in a coloration which is insufficient as to the homogeneity of the color distributed along the dye. Fibers (harmony) in terms of color (clarity), color intensity, and resistance to various aggressive factors to which hair may be exposed. (*) · · · · · · · · · · · · · · · ·

It is known that most conventional techniques for obtaining permanent modeling consist in the first step of opening keratin -SS-disulfide (cysteine) bonds using a composition comprising a suitable reducing agent (reducing step), followed by rinsing such treated hair by reconstitution in the second step. disulfide bonds by applying to hairs that have been previously stretched (curlers, etc.) of an oxidizing agent (an oxidation stage, also known as a fixation stage), so that hair of the desired shape is finally obtained. This technique makes it equally either to achieve curled hair or straighten it after curling. The new shape given to the hair by chemical treatment as mentioned above has a considerably longer shelf life and is particularly resistant to shampooing with water, compared to simple standard techniques for temporary modeling, such as water waving.

Reducing agents which may be used to perform the first stage of permanent hair styling include, as reducing agents, sulfites, bisulfites, alkylphosphines or preferably thiols. As thiols, cysteine and its various derivatives, cysteamine and its derivatives, thiol acetic acid or thiol glycolic acid, their salts and esters, in particular glyceryl thioglycolate, are usually used.

With regard to the oxidizing agents required to perform the fixation step, in practice compositions based on aqueous hydrogen peroxide, sodium bromate or persalts such as perborate, which have the disadvantages of hair damage, are commonly used.

A problem with permanent waving techniques known to date is that its application to the hair induces long-term adverse changes in hair quality. The underlying causes of these adverse changes in hair quality are a reduction in their cosmetic properties such as shine and their feel and degradation of their mechanical properties, in particular degradation of mechanical strength due to swelling of keratin fibers during rinsing between the reduction stage and the oxidation stage, their porosity. Hair becomes thin and becomes brittle during subsequent treatment, for example, by blow drying.

The same problem of adverse changes in keratin fibers is encountered in hair bleaching processes.

It is known that permanent modeling or bleaching of keratin fibers can also be performed under milder conditions, using oxidation systems other than hydrogen peroxide, such as enzyme systems. Processes for the permanent waving or bleaching of keratin fibers have already been proposed, in particular in patent application EP-A-0 310 675, compositions comprising an enzyme such as pyranose oxidase, glucose oxidase or uricase in the presence of a donor for said enzyme. Although used under conditions which do not lead to degradation of keratin fibers comparable to degradation caused by conventional crimping or bleaching processes, these oxidation formulations nevertheless produce results that are still inadequate as to the compatibility of curly or bleached hair with subsequent treatment, and as regards the reduction of the mechanical properties of permanent curly hair, in particular the reduction of the porosity of the hair and the reduction of the cosmetic properties, such as the touch, or alternatively regarding the uniformity of discoloration along keratin fibers.

SUMMARY OF THE INVENTION

The Applicant has surprisingly discovered novel compositions comprising as oxidation system at least one oxidoreductase enzyme having 2 electrons in the presence of at least one donor for said enzyme and at least one substantive polymer, which will be defined in more detail below which they may form, in the presence of oxidizing bases and optionally coupling agents, ready-to-use formulations which result in more homogeneous, intense and colored dyes without increasing degradation of keratin fibers, the dyes being relatively non-selective and showing good resistance to the various aggressive factors to which the hair may be exposed.

The Applicant has further unexpectedly discovered that the use of an oxidizing agent comprising, as an oxidation system, at least one 2-electron oxidoreductase enzyme in the presence of at least one donor for said enzyme and at least one specific substantive polymer is a possible solution to the problem. In particular, this type of oxidizer improves the durability of the curl over time, substantially reduces the porosity of the permanently formed hair and improves the compatibility of the permanently waved hair with respect to subsequent treatment.

In general, the acid addition salts that can be used in the context of the coloring compositions of the invention (oxidizing bases and coupling agents) are particularly selected from hydrochlorides, hydrobromides, sulfates, tartarates, lactates and acetates.

The dye compositions of the invention may also contain, in addition to the oxidative dye precursors defined above and optionally combined coupling agents, direct dyes to enrich shades. These direct dyes may in particular be selected from nitro-dyes, azo-dyes and anthraquinone dyes.

The present invention also provides a method for dyeing keratin fibers, particularly human keratin fibers such as hair, by using ready-to-use coloring agents as defined above.

According to this process, the at least one ready-to-use dye composition as defined above is applied to the fibers for a period of time sufficient to develop the desired coloration, after which the hair is rinsed, optionally washed with shampoo, and rinsed and dried again.

The time required to develop coloring to keratin fibers is usually between 3 and 60 minutes, more preferably between 5 and 40 minutes.

According to one specific embodiment of the invention, the process comprises a first step comprising, on the one hand, a separately deposited composition A comprising in the environment suitable for dyeing at least one oxidizing base and optionally at least one coupling agent as defined above, and B, containing flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl flfl dyeing at least one 2-electron oxidoreductase enzyme in the presence of at least one donor for said enzyme and at least one substantive polymer as defined above and mixing them at the time of use prior to application of the composition to keratin fibers.

According to another specific embodiment of the invention, the substantive polymer is incorporated into composition A.

A further object of the invention is a multi-compartment dyeing kit or device or multi-compartment equipment or any multi-compartment packaging system comprising in the first compartment composition A as defined above and in the second compartment composition B as defined above. The device may be provided with means to apply the desired composition to the hair, such as the device described in French Patent No. 2,586,913 filed under the name of the applicant of the present invention.

It is also an object of the present invention to provide a novel method of treating keratin substance, particularly hair, to obtain a permanent treatment of such hair, particularly in the form of a permanent model, the process comprising the following steps: (i) a reducing agent is applied to the keratin substance to be treated wherein the keratin substance is first placed on the mechanical tensioning means, (ii) the keratin substance is optionally rinsed, (iii) an oxidizing agent as defined above is applied to the optionally rinsed keratin substance, (iv) the keratin substance is optionally rinsed again.

The first step (i) of this process consists in applying a hair reducing agent. This application is done individually or at a time.

For example, the reducing agent comprises at least one reducing agent, which may be selected, in particular, from thioglycolic acid, cysteine, cysteamine, glycerol thioglycolate, thiolactic acid or thiolactic and thioglycolic acid salts.

The usual tensioning of the hair to a shape corresponding to the desired final shape for the hair (e.g., curls) can be accomplished by suitable means, in particular by suitable mechanical means which are suitable and known per se to maintain tight hair, such as curlers and the like.

The hair can also be shaped without the aid of external means, simply by fingers.

Before performing the optional rinsing (ii), the hair to which the reducing agent has been applied can be allowed to stand for several minutes, usually between 5 minutes and 1 hour, preferably between 10 and 30 minutes, so that the reducing agent has sufficient time to act on the hair. This phase is usually carried out at a temperature of from 35 ° C to 45 ° C, the hair preferably being protected by a cap.

In the optional second process step (step (ii)) the hair impregnated with the reducing agent is thoroughly rinsed with water.

Further, in the third step (step (iii)), the oxidizing agent of the invention is applied to the rinsed hair thus fixed with a new hair shape.

Similar to the application of the reducing agent, the hair to which the oxidizing agent is applied is then left to rest for at least several minutes, usually between 3 and 30 minutes, preferably between 5 and 15 minutes.

If the hair is kept taut by external means, these means (e.g., curlers) are removed from the hair before or after the fixation stage.

Finally, in the final step according to the invention (step (iv)), which is also optional, the hair impregnated with the oxidizing agent is rinsed thoroughly, usually with water.

Soft hair is obtained which is easy to comb. The hair is wavy.

The oxidizing agent according to the invention can also be used in decolorizing keratin fibers, in particular hair.

The decolorizing step of the invention comprises the step of applying an oxidizing agent of the invention to keratin fibers in the presence or absence of an oxidizing auxiliary. Conventionally, the second step of the bleaching process of the invention is the step in which the keratin fibers are rinsed.

An environment suitable for keratin fibers (or carrier) for ready-to-use colorants and oxidizing agents used for the permanent modeling or decolorization of keratin fibers according to the invention usually consists of water or a mixture of water and at least one organic solvent to dissolve the compounds which are not sufficiently soluble in water.
