Cosmetic composition for the oxidation dyeing of keratin fibres comprising a cationic polymer and a particular combination of
surfactants
The present invention relates to a cosmetic composition for the oxidation dyeing of keratin fibres, in particular human keratin fibres such as the hair.
More precisely, a subject of the present invention is a dyeing cosmetic composition comprising one or more oxidation dyes, one or more cationic polymers and a particular combination of surfactants.
The present invention also relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, using the composition according to the invention.
At last, the present invention relates to a kit for the oxidation dyeing of keratin fibres, which is suitable for performing the process of the invention.
Many people have for a long time sought to modify the colour of their hair, and especially to dye it in order, for example, to mask their grey hair.
"Permanent" dyeing methods also known as oxidation dyeing, which use dye compositions containing oxidation dye precursors, generally referred to as oxidation bases, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic compounds, have been developed for dyeing human keratin fibres in a long-lasting manner. These oxidation bases are colourless or weakly coloured compounds, which, when combined with oxidizing products, may give rise to coloured compounds via 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 coloration modifiers, the latter being chosen especially from aromatic meta-diaminobenzenes, meta-aminophenols, meta-diphenols and certain heterocyclic compounds such as indole compounds.

As an example of compositions known in the prior art, mention may be made of WO 2011/138838 which discloses a ready-to-use composition for the oxidation dyeing of keratin fibers comprising, in an aqueous medium at least one oxidation dye, at least one oxidizing agent, and at least 1.5% by weight of at least one amphoteric surfactant.
However, the prior art compositions are not entirely satisfactory, and their performance qualities can be further improved, in particular as regards the working qualities (whether or not the composition is mixed with an oxidizing composition before application), especially in terms of texture, ease of application and ease of spreading of the composition on the keratin fibres. Furthermore, the compositions of the prior art are not always sufficiently stable, and their coloring performances can also be further improved, especially in terms of intensity, homogeneity and selectivity of the dyeing obtained.
The Applicant has now discovered that the use of a cationic polymer together with a particular combination of surfactants makes it possible to obtain a cosmetic composition for the oxidation dyeing of keratin fibres, which can overcome the above drawbacks and which has further improved properties.
One subject of the present invention is thus a cosmetic composition for the oxidation dyeing of keratin fibres comprising:
a) one or more oxidation dye(s),
b) one or more cationic polymer(s),
c) one or more amphoteric or zwitterionic surfactant(s),
d) one or more non ionic surfactant(s) chosen from
alkanolamides of C6-C30 fatty acids, and
e) one or more anionic surfactant(s), in an amount of at least
1.5% by weight, with regard to the total weight of the composition.
The composition according to the invention has very good working qualities, and especially a particularly pleasant texture and a good viscosity (neither too thick, nor too fluid which facilitates its use). This property is very stable over the time, and does not diminish

even after several months of storage at ambient temperature (25°C) as well as from low temperatures (such as 4°C) until high temperatures (such as 45°C).
The composition further exhibits excellent foaming properties similar to those of a shampoo, whenever or not is mixed with a developer composition (or oxidizer), and it is very easy to apply and to spread on the locks of hair, in particular from the roots to the ends. More particularly, the composition of the present invention allows an easy an rapid formation of foam, such as immediately after massaging the hair. The foam is firm and creamy and allows a good dyeing performance. Moreover, the foam stays on the hair without flying away.
In addition, the composition of the invention does not require premixing with a developer composition or oxidizing composition or oxidizer. It allows to be used simultaneously with a developer or oxidizer directly on the hair, without a step of premixing.
In addition, it does not run and remains well located at the points of application in particular on the roots, while being very easy to rinse off from the hair after application
Furthermore, the composition of the invention has very good cosmetic properties, and provides the keratin fibres with an excellent conditioning. In particular, after dyeing with such a composition the hair is shiny, smooth, supple and easy to disentangle.
At last, the composition according to the invention has superior dyeing quality, especially in terms of intensity, homogeneity and selectivity of the dyeing obtained.
The composition of the invention is intended to be used in a process for dyeing keratin fibres either as a ready-to-use composition when it contains an oxidizing agent, or in combination with an oxidizing composition.
A subject of the invention is thus also a process for dyeing keratin fibres, which consists in applying to the keratin fibres the composition of the invention. Said composition may be applied sequentially to or simultaneously with an oxidizing composition comprising one or more oxidizing agents.

Needless to say, a person skilled in the art will take care to select this or these optional additional compound(s) such that the advantageous properties intrinsically associated with the invention are not, or are not substantially, adversely affected by the envisaged addition(s).
The above adjuvants may generally be present in an amount, for each of them, of between 0 and 20% by weight relative to the total weight of the composition.
According to one embodiment of the invention, the composition further comprises one or more oxidizing agents. The composition is then said to be "ready to use" in the sense that it does not require the use of a separate oxidizing composition.
Advantageously, the oxidizing agent(s) used in the context of the invention are chemical oxidizing agents other than atmospheric oxygen.
The said oxidizing agent(s) are preferably chosen from the group formed by hydrogen peroxide, urea peroxide, alkali metal bromates or ferricyanides, peroxygenated salts, for instance persulfates, perborates, peracids and precursors thereof and alkali metal or alkaline-earth metal percarbonates, and most particularly hydrogen peroxide.

The oxidizing agent(s) may represent from 0.01% to 20%, preferably from 0.1 % to 10% and better still from 2% to 8% by weight, relative to the total weight of the composition.
The compositions according to the invention may be in the form of fluid or thickened liquids, gels or creams.
They advantageously have a viscosity, measured at ambient temperature and atmospheric pressure, ranging from 10 to 100 UD, preferably from 20 to 80 UD, and even more preferably from 50 to 70 UD, when using rotor 3 under 200 rpm for 30 seconds. The viscosity of the composition of the present invention is measured using a ProRheo R180 machine from the company Prorheo, Roter 3 is used adapted to the viscosity of the composition to be tested (rotor is chosen for having a measure between 10 and 100 for UD Unit Deviation), the measure being made after 30 seconds rotating the rotor inside the composition, with a shear rate from 200s"1. The UD values may then be converted in Poises (1 Poise= O.lPa.s) with a correspondence table.
The invention also relates to the use of the composition as described above for dyeing keratin fibres, in particular the hair.
Another subject of the invention is a process for dyeing human keratin fibres, in particular the hair, using the composition as described above.
According to a first preferred embodiment of the invention, the composition is "ready to use", i.e. it already contains at least one oxidizing agent.
In this case, the dyeing process of the invention consists in applying the "ready-to-use" composition to the keratin fibres.
According to a second preferred embodiment, the dyeing process of the invention consists in applying the composition as described above to the keratin fibres, the said composition being applied with a separate oxidizing composition.
The oxidizing composition that is used in this embodiment of the process of the invention comprises one or more oxidizing agents.

The oxidizing agent(s) of the oxidizing composition are as defined above, ie, they are preferably chosen from the group formed by hydrogen peroxide, urea peroxide, alkali metal bromates or ferricyanides, peroxygenated salts, for instance persulfates, perborates, peracids and precursors thereof and alkali metal or alkaline-earth metal percarbonates, and most particularly hydrogen peroxide.
The oxidizing agent(s) may represent from 0.01% to 20%, preferably from 0.1 % to 10% and better still from 2% to 8% by weight, relative to the total weight of the oxidizing composition.
In one variant of the second embodiment above, the composition according to the invention is mixed at the time of use with the oxidizing composition as described above.
More particularly, by "mixed" it is intended to mean the action of putting the composition of the present invention into a container or palm, together with the oxidizing composition as described above, with or without stirring them.
According to a preferred variant of the second embodiment, the composition of the present invention is put into a container or palm together with the oxidizing composition as described above, without stirring them.
Indeed, due to the very good foaming properties of the composition of the invention, it is particularly advantageous and convenient to apply onto the keratin fibers the composition of the invention and an oxidizing composition without the need of stirring them in a container or palm, but apply them directly on the hair, and allow the mixture thus formed onto the hair to foam for example by massaging with the fingers.
Irrespective of the process used and the number of compositions used, the composition(s) described previously, optionally mixed beforehand, are applied to wet or dry keratin fibres.
The composition(s) are usually left in place on the fibres for a time generally ranging from 1 minute to 1 hour and preferably from 5 minutes to 30 minutes.

The temperature during the process is conventionally between 20 and 80°C and preferably between 20 and 60°C. After the treatment, the human keratin fibres are advantageously rinsed with water. They may optionally be further washed with a shampoo, followed by rinsing with water, before being dried or left to dry.
The process may be repeated several times in order to obtain the desired coloration.
Another subject of the invention concerns a multi-compartment device, or a kit for dyeing keratin fibres, comprising at least two compartments:
- a first compartment containing a dyeing composition as
described above; and
- a second compartment containing an oxidizing composition as
described above.
According to one variant of the invention, the kit also comprises an additional compartment containing an additional composition comprising one or more treating agents.
The compositions of the kit are packaged in separate compartments, which may be optionally accompanied by suitable identical or different application means, such as fine brushes, coarse brushes or sponges.
The abovementioned kit may also be equipped with means allowing the delivery to the hair of the desired mixture, such as, for example, the device described in patent FR 2 586 913.
The examples that follow are given purely as illustrations of the present invention.
EXAMPLES:
Example 1
The dyeing compositions hereunder were prepared, from the ingredients indicated in the table below (in which the contents are

indicated in grams of active material with regard to the total weight of the composition):

Composition C4 corresponds to the invention, whereas compositions CI to C3 correspond to comparative compositions.
The compositions above were tested with regard to the following properties:
Stability on storage of the composition: Stability on storage was performed by leaving the compositions CI to C4 at 4°C, room temperature (25°C), and 45°C for 2 months. Then CI to C4 were left under 37°C for 6 months to evaluate the long term stabilities.

Viscosity of the composition: The viscosities of the compositions CI to C4 were measured at 25°C, using a ProRheo R180 machine from the company Prorheo, Roter 3 was used adapted to the viscosity of the product to be tested (rotor is chosen for having a measure between 10 and 100 for UD Unit Deviation), the measure being made after 30 seconds rotating the rotor inside the composition, with a shear rate from 200s"1. The UD values may then be converted in Poises (1 Poise= O.lPa.s) with a correspondence table.
Ease of application onto the keratin fibers: The ease of application onto hair of the compositions CI to C4 was measured by 3 hair dressers using the compositions CI to C4 for dyeing the hair. 30g of the compositions CI to C4 were poured in the palm of the hair dressers, respectively, together with same amount of an oxidizer containing 6% of hydrogen peroxide. Without mixing, the hair dressers applied the products (compositions CI to C4 mixing with oxidizers) immediately onto the middle-length hair, i.e., hair length is at the shoulder. The hair were massaged and foam was formed. After 15 minutes, the hair with the products mentioned above were rinsed with water.
For each property, a score was attributed to each composition on a scale ranging from 1 to 5 as follows
1: very bad
2: not good
3: acceptable
4: good
5 perfect
The results are given in the table hereunder:


The results hereabove clearly show that the particular combination of surfactants of the composition of the invention allows achieving superior performances in terms of working qualities and stability.
Example 2
A dyeing composition in accordance with the invention was prepared, from the ingredients indicated in the table below (in which the contents are indicated in grams of active material with regard to the total weight of the composition):


30g of the composition prepared above was poured in a palm together with 30g of an oxidizer containing 6% of hydrogen peroxide. Without mixing, the compositions were applied immediately onto the middle-length hair, i.e., hair length is at the shoulder. The hair was massaged and foam was formed. After 15 minutes, the hair was rinsed with water.
The viscosity of the composition mentioned above is 63.8 UD, using the measurement method disclosed in example 1 above. It allows the composition staying in the palm without floating away. And furthermore, when mixing with the oxidizer on the hair, it allows the mixture and the foam staying on the hair without dropping or flying.
The turbidity of the composition mentioned above is 6 NTU, using the measurement method disclosed in the above description.
It is a clear and transparent composition, which is very pleasant to the consumers.
The composition mentioned above is stable over 2 months under 4°C, room temperature, and 45°C.
Inventors observed that without waiting for a long period of time, the hair was dyed as expected. Within 15 minutes staying on the hair, the gray hair was covered perfectly.
