7.Description:
(en)This application claims benefit of U.S. Provisional Application No. 61/144,217, filed Jan. 13, 2009. This application also claims benefit of priority under 35 U.S.C. §119 to French Patent Application No. 0858838, filed Dec. 19, 2008.


Provided is a composition for the treatment of keratin fibers, for example human keratin fibers such as the hair, comprising, in a cosmetically acceptable medium, at least one cationic polymer; at least one fatty amide; at least one anti-oxygen agent; and at least one oxidizing agent.
In cosmetics, in the areas of dyeing, bleaching, and permanent deformation of keratin fibers, for example human keratin fibers such as the hair, oxidizing compositions are often used.
Thus, in oxidation dyeing of the hair, oxidizing compositions may be mixed with oxidation dyes (bases and couplers), which may be colorless in themselves, to produce colored and coloring compounds by a process of oxidative condensation. Oxidizing compositions may also be used in direct dyeing of the hair mixed with certain direct dyes which are colored and coloring, to obtain coloration with a hair-lightening effect. The oxidizing agents used conventionally for the dyeing of keratin fibers include for example hydrogen peroxide or compounds that can produce hydrogen peroxide by hydrolysis, such as urea peroxide. Persalts such as perborates and persulphates can also be used. Hydrogen peroxide for example can also be used.
In hair bleaching, the bleaching compositions may contain at least one oxidizing agent. Among these oxidizing agents, those conventionally used are for example hydrogen peroxide or compounds that can produce hydrogen peroxide by hydrolysis, such as urea peroxide or persalts such as perborates, percarbonates, and persulphates, hydrogen peroxide and persulphates being for example used.
These compositions can be aqueous compositions containing alkaline agents (amines or ammonia), which are diluted at the moment of use with an aqueous composition of hydrogen peroxide.
These compositions can also be formed from anhydrous products that contain alkaline compounds (amines and/or alkaline silicates), and a peroxidized reagent such as persulphates, perborates, or percarbonates, of ammonium or of alkali metals, which are diluted at the moment of use with an aqueous composition of hydrogen peroxide.
In permanent deformation of the hair, first the disulphide bonds —S—S— of the keratin (cystine) can be opened using a composition containing a suitable reducing agent (reduction stage) then, after rinsing the hair thus treated, secondly the disulphide bonds can be reconstituted by applying, on the hair previously put under tension (curlers etc.), an oxidizing composition (oxidation stage, also called fixation) so as finally to give the hair the desired form. This technique thus may make it possible to carry out either waving or straightening of the hair. The new shape imposed on the hair by chemical treatment as described above may be long-lasting and may withstand the action of washing with water or shampoos, in contrast to the conventional techniques of temporary waving, such as a water wave.
The oxidizing compositions used in the fixation stage are generally compositions based on hydrogen peroxide.
Moreover, in the cosmetic field, improved conditioning of the hair is desirable, i.e., for example improving the properties of smoothness and softness to the touch.
To do this, the use of cationic molecules is known, for example cationic polymers or cationic surfactants for improving fiber conditioning.
However, the inclusion of cationic polymers in oxidizing compositions based on hydrogen peroxide may lead to destabilization of these compositions.
Provided is a composition for the treatment of keratin fibers, for example human keratin fibers such as the hair, comprising, in a cosmetically acceptable medium:
at least one cationic polymer;
at least one fatty amide;
at least one anti-oxygen agent; and
at least one oxidizing agent.
Also provided is a composition for the treatment of keratin fibers comprising, in a cosmetically acceptable medium:
at least one cationic polymer;
at least one fatty amide;
at least one anti-oxygen agent; and
at least one oxidizing agent;
wherein the pH of the composition ranges from 1.5 to 4.5.
Also provided is a composition for the treatment of keratin fibers comprising, in a cosmetically acceptable medium:
at least one cationic polymer;
at least one fatty amide;
at least one anti-oxygen agent selected from vitamin E and the ethers and esters thereof; and
at least one oxidizing agent;
wherein the pH of the composition is alkaline.
When the composition described herein is used for coloring keratin fibers, good dyeing properties may be obtained, for example strong, chromatic coloring, low selectivity, and good resistance to the various aggressive factors to which the hair may be subjected, such as shampoos, light, sweat, and permanent deformation, without affecting the cosmetic properties of the keratin fibers.
When the composition described herein is used for the bleaching of keratin fibers, it may provide a good lightening effect of the fibers without degrading them and without affecting their cosmetic properties.
When the composition described herein is used for the permanent deformation of keratin fibers, it may provide satisfactory permanent deformation of the fibers without degrading them and without affecting their cosmetic properties.
Moreover, the composition described herein may have good stability over time, such as in storage at high temperatures, for example at a temperature of 45° C.
Also provided is a method for treating keratin fibers, such as a method for coloring, bleaching, or permanent deformation of keratin fibers, employing at least one oxidizing composition described herein.
Also provided is a method for making this oxidizing composition for treating keratin fibers.

The hair can also be shaped without using external aids, such as with the fingers.
Before optionally rinsing, the hair on which the at least one reducing composition has been applied should, conventionally, be left for some minutes, generally for a period of time ranging from 5 minutes to one hour, such as from 10 to 30 minutes, to give the at least one reducing agent time to act on the hair. This waiting period may for example be carried out at a temperature ranging from 35° C. to 45° C., for example while also protecting the hair with a cap.
The optional rinsing may be accomplished by carefully rinsing the hair impregnated with the at least one reducing composition with an aqueous composition.

As in the case of application of the at least one reducing composition, the hair to which the at least one oxidizing composition has been applied may then, conventionally, be left alone for a resting or waiting period, which may last for a period of some minutes, for example ranging from 3 to 30 minutes, such as from 5 to 15 minutes.
If the tension of the hair has been maintained by external means, the latter (rollers, curlers and the like) can be removed from the hair before or after the fixation stage.
