Description

l

Keratin fiber treatment process comprising the application of a washing composition, a care composition and then a beneficial composition

The present invention relates to a process for cosmetically treating keratin materials, in particular keratin fibers and especially human keratin fibers such as the hair, which consists in sequentially applying a cosmetic washing composition, a cosmetic care composition comprising one or more cationic surfactants and one or more fatty alcohols, and a cosmetic composition comprising one or more anionic direct dyes or anionic screening agents.

Dyeing of the hair is generally based on chemical reactions and transformations that are liable to damage the hair fiber. Milder solutions, known as makeup solutions and based on weak physicochemical interactions, make it possible to deposit dyes at the surface without harming the fiber integrity.

Thus, it is known practice to dye keratin fibers and in particular human hair with dye compositions containing "direct" dyes, which are colored or coloring molecules that have affinity for keratin fibers, and among which mention may be made in particular of dyes of nitrobenzene, anthraquinone, nitropyridine, azo, xanthene, acridine, azine and triarylmethane type or natural dyes. Compositions containing one or more direct dyes are applied to the keratin fibers for a time necessary to obtain the desired coloring, and are then rinsed out. The colorings that result therefrom are particularly chromatic colorings which are, however, temporary or semi-permanent since the nature of the interactions that bind the direct dyes to the keratin fiber and their de- sorption from the surface and/or the core of the fiber are responsible for their weak dyeing power and their poor persistence with respect to light, washing or perspira- tion. These compositions are thus generally intended for dyeing fibers for a short period, for example withstanding one or two shampoo washes. The persistence of this type of hair makeup/coloring may be improved by succes- sively applying a fiber cationizing treatment, for example a shampoo containing and depositing cationic polymers, immediately followed by an anionic dye solution. Such coloring proves to be only partially satisfactory since it nonetheless fades out in the course of shampoo washes. In addition, certain cosmetic properties of the fiber such as the feel quality, the softness, the suppleness, and the final dye result, more par- ticularly the uniformity of the color, are not always satisfactory and can also be im- proved.

There is thus a real need to find a cosmetic treatment process for imparting quality coloring to the hair, especially in terms of uniformity of the color, without harming the fiber integrity; this thus also makes it possible to obtain improved fiber qualities, in particular in terms of feel, softness, suppleness and disentangling.

In addition, by means of the process according to the invention, an improvement in the persistence of the color with respect to shampooing (improved color persistence) is observed; this process thus also makes it possible to protect the color of dyed hair with respect to washing.

Without wishing to be bound by the present explanation, it may be thought that step (b) consisting in applying a composition comprising a cationic surfactant and a fatty alcohol modifies the charges present at the surface of the hair and thus promotes more intense and homogeneous deposition of the anionic direct dyes and/or of the anionic screening agents present in composition C. Better uniformity of the depos- ited color, improved cosmetic benefit and improved persistence and/or protection of the color and/or UV protection are thus obtained.

The term "cosmetic benefit" especially means the conditioning properties such as the smooth nature (visual and/or feel), the suppleness, the softness and/or the dis- entangling.

One subject of the present invention is thus a cosmetic process for treating keratin fibers, in particular human keratin fibers such as the hair, comprising:

- at least one step (a) of applying to said keratin fibers a washing cosmetic compo- sition A comprising

(i) one or more anionic surfactants chosen, alone or as a mixture, from poly- oxyalkylenated alkyl(amido)ether carboxylic acids and salts thereof;

(ii) one or more anionic surfactants other than the polyoxyalkylenated al- kyl(amido)ether carboxylic acid anionic surfactants (i);

(iii) one or more nonionic surfactants;

(iv) one or more amphoteric surfactants; and

(v) one or more cationic polymers and/or one or more amphoteric polymers;

- at least one step (b) of applying to said keratin fibers a cosmetic care composition B comprising

(i) one or more cationic surfactants, and

(ii) one or more fatty alcohols preferably comprising at least 8 carbon atoms,

- at least one step (c) of applying to said keratin fibers a cosmetic composition C comprising one or more anionic dyes and/or anionic screening agents.

Preferably, the cosmetic washing composition A according to the process of the invention comprises (v) one or more cationic polymers and one or more amphoteric polymers.

A subject of the present invention is also a process for dyeing and/or antisun-pro- tecting keratin fibers, in particular human keratin fibers such as the hair, comprising:

- at least one step (a) of applying to said keratin fibers a washing cosmetic compo- sition A comprising (i) one or more anionic surfactants chosen, alone or as a mixture, from poly- oxyalkylenated alkyl(amido)ether carboxylic acids and salts thereof;

(iii) one or more nonionic surfactants;

(iv) one or more amphoteric surfactants; and

(v) one or more cationic polymers and/or one or more amphoteric polymers;

(i) one or more cationic surfactants, and

(ii) one or more fatty alcohols preferably comprising at least 8 carbon atoms,

- at least one step (c) of applying to said keratin fibers a cosmetic composition C comprising one or more anionic dyes and/or one or more anionic sunscreens.

Surprisingly, it has been found that the color could be persistent after at least 10 shampoo washes.

Implementation of the invention makes it possible especially to obtain the desired properties immediately on application, and in particular suppleness, smoothness, volume and a non-charged, natural feel of the coloring and/or UV protection, while at the same time keeping the hair strands light and individualized; this process most particularly gives the hair improved capacity for disentangling.

In the case of coloring with anionic direct dyes, the dyeing performance qualities are improved relative to the usual results; this may be reflected by a shorter leave-on time and/or a lower concentration of anionic dye in the composition to achieve the desired level of dyeing. It has also been observed that these desired properties, obtained on implementing the invention, are especially persistent with respect to shampoo washing.

Specifically, it has been found that the process according to the invention can im- prove the persistence of the conditioning (or of the conditioning properties) and/or of the coloring and/or protection afforded; the conditioning properties may especially be persistent on shampoo washing at least three times, in particular on shampoo washing at least four times, and better still shampoo washing at least five times, or even shampoo washing at least six times.

The particularly persistent conditioning properties are especially the suppleness of the hair, and/or its smooth feel (smoothing) and/or its ease of disentangling.

Moreover, it has also been found that the use of a washing composition A according to the invention has a sparingly aggressive nature, since the application of the corn- position to the hair fiber in the long run causes little damage associated in particular with the gradual removal of the lipids or proteins contained in or at the surface of said fiber. In addition, the washing composition A according to the invention allows good deposition, or even good penetration, of the anionic beneficial agents on/in the keratin fibers and thus makes it possible to obtain improved conditioning action. The time which separates the application of the washing composition A from the application of composition C according to the invention depends on the consumers’ need to wash their hair and/or the frequency at which they perform their shampoo washes. There are no particular constraints regarding this time, which may range from a few minutes (the application of the washing composition A is immediately followed by the application of composition B and then of composition C) to a few days; this time may especially range from 30 seconds to 7 days, for example from 1 minute to 4 days, better still from 2 minutes to 3 days, or even from 5 minutes to 48 hours, and better still from 10 minutes to 24 hours.

Preferably, composition B is applied to wet hair, after rinsing out composition A, preferably immediately after rinsing out composition A. Preferably, composition B is left to stand on the hair for a time ranging especially from 1 to 15 minutes, better still from 2 to 10 minutes and ideally 4-6 minutes.

Composition C is advantageously applied to wet hair, after rinsing out composition B, preferably immediately after rinsing out composition B. Preferably, composition C is left to stand on the hair for a time ranging especially from 1 to 15 minutes, better still from 2 to 10 minutes, ideally 4-6 minutes; before rinsing out composition C (rins- ing of the hair).

Preferentially, composition C is applied immediately after composition B, which is itself applied immediately after the washing composition A; the term "immediately" means a time of the order of 1 to 15 minutes, especially of the order of 2 to 10 minutes.

In the present description, the term“care composition" denotes a composition which can afford haircare, especially conditioning; it is a cosmetic composition, especially a hair composition, and not at all a pharmaceutical or therapeutic composition. In the present description, the expression "at least one" is equivalent to the expres- sion "one or more" and can be replaced therewith. The expression "between" is equivalent to the expression "ranging from... to" and can be replaced therewith, and implies that the limits are included. Washing composition A

The cosmetic washing composition A used in the context of the invention comprises one or more anionic surfactants chosen from polyoxyalkylenated alkyl(amido)ether carboxylic acids and salts thereof (i) and one or more additional anionic surfactants (ii), other than the anionic surfactants (i).

Thus, for the purposes of the invention, the washing composition A comprises at least two different anionic surfactants.

The term "anionic surfactant" means a surfactant comprising, as ionic or ionizable groups, only anionic groups. In the present description, a species is termed "anionic" when it bears at least one permanent negative charge or when it can be ionized into a negatively charged spe- cies, under the conditions of use of the washing composition A and/or B of the in- vention (for example the medium or the pH) and not comprising any cationic charge.

The pH of the washing composition A generally ranges from 3 to 7, preferably from 3.5 to 6.5, preferentially from 4 to 6 and better still from 4.2 to 5.5.

Preferably, the care composition B has a water content of between 50% and 99% by weight, preferably between 60% and 98%, preferentially between 70% and 95% by weight and better still between 80% and 95% by weight relative to the total weight of the composition.

The pH of the care composition B generally ranges from 3 to 7, preferably from 3.5 to 6 and better still from 3.5 to 5. Preferably, the cosmetic composition has a water content of between 70% and 99.99% by weight, preferably between 75% and 99.95%, preferentially between 80% and 99.90% by weight relative to the total weight of the composition.

The pH of composition C generally ranges from 3 to 7, preferably from 3.5 to 6 and preferentially from 4 to 5.

The pH of these compositions may be adjusted to the desired value by means of basifying agents or acidifying agents that are usually used. Among the basifying agents, examples that may be mentioned include aqueous ammonia, alkanola- mines, and mineral or organic hydroxides. Among the acidifying agents, examples that may be mentioned include mineral or organic acids, for instance hydrochloric acid, orthophosphoric acid or sulfuric acid, carboxylic acids, for instance acetic acid, tartaric acid, citric acid and lactic acid, and sulfonic acids.

The cosmetic treatment process according to the invention comprises a step that consists in applying to said keratin fibers a cosmetic washing composition A as de- fined above.

This step may be followed by a step of leaving the composition on, for example a leave-on time of 1 to 15 minutes and especially 2 to 5 minutes; it may also be fol- lowed by a rinsing step, for example with water, and/or a drying step.

Preferably, the step of applying composition A is followed by rinsing only, i.e. without a drying step.

The cosmetic treatment process according to the invention also comprises a step that consists in applying to said keratin fibers a cosmetic composition B as defined above.

This step may be followed by a step of leaving the composition on, for example a leave-on time of 1 to 30 minutes and especially 2 to 20 minutes; it may also be followed by a rinsing step, for example with water, and/or a drying step.

Preferably, the step of applying composition B is followed by rinsing, optionally fol- lowed by drying; preferentially, there is no drying.

The cosmetic treatment process according to the invention also comprises a step that consists in applying to said keratin fibers a cosmetic composition C as defined above.

Preferably, the step of applying composition C is followed by rinsing, and by drying. The step of applying composition C may also be followed by a step of heat treatment of the fibers using a heating tool, for example with the aid of a straightening or curling iron, for example from 40 to 250°C, preferably 40-100°C or even 40-80°C, for ex- ample with a hairdryer, a hood, or even a hood of Climazon type.

The step of applying the washing composition A, the step of applying composition B and the step of applying composition C are performed successively, or sequen- tially, which means that the step of applying the washing composition A comes be- fore the step of applying composition B, which itself comes before the step of apply- ing composition C; intermediate steps, for example of leaving to stand and/or of rinsing and/or of drying, may be present between these three application steps.

Preferentially, the process comprises at least the following steps:

- at least one step of applying the washing composition A according to the invention, optionally followed by rinsing, this step possibly being repeated a certain number of times, and then

- at least one step of applying composition B according to the invention, optionally followed by rinsing and drying, this step possibly being repeated a certain number of times, and then

- at least one step of applying composition C according to the invention, optionally followed by rinsing and drying.

The examples that follow serve to illustrate the invention without, however, being limiting in nature. In these examples, all the amounts are indicated as weight per- centages of active material (AM) of product, unless otherwise indicated.

Example 1 : Compositions

The following compositions were prepared (content expressed as percentage by weight of active material).

1/ Washing compositions A1 and A2 (weight % of AM)

2/ Care composition B1 (Weight % of AM)

3/ Dye composition C1 (Weight % of AM)

Example 2

A shampoo is applied to a malleable wet mini-head at a rate of 2 g of shampoo per half-head. On one side, the formulation applied is shampoo A1 of example 1 ; on the other side, it is a commercial shampoo formulation (Total Repair 5 from Elseve). After rinsing out the shampoos (water 38°C, flow rate 3 l/minute), 4 g of care corn- position B1 above are applied to the entire malleable mini-head (i.e. 2 g per half- head). The composition is left on for 5 minutes and then rinsed out (water 38°C, flow rate 3 l/minute).

12 g of dye composition C1 are then applied (i.e. 6 g per half-head), the composition is left on for 5 minutes, and is then rinsed out (water 38°C, flow rate 3 I/minute) and drying is performed with a hairdryer.

It is found that the red coloring is markedly more intense on the part pretreated with shampoo A1 .

The mini-head then underwent a cycle of 10 shampoo washes, each shampoo wash being followed by a step of rinsing and of drying with a hairdryer, before the next shampoo wash; the shampoo used is a commercial shampoo (DOP chamomile). After the 10 cycles of shampooing/rinsing/drying, it is found that the color, although attenuated, persists on the side treated according to the invention; for the other side, the color is almost no longer perceptible (very attenuated) but remains slightly pre- sent; however, it is very non-uniformly distributed.

Example 3

A shampoo A1 of example 1 is applied to a malleable wet mini-head at a rate of 4 g of shampoo for the entire head (i.e. 2 g per half-head).

After rinsing out the shampoos (water 38°C, flow rate 3 I/minute), 2 g of care corn- position B1 above are applied to one side of the malleable mini-head. Nothing is applied to the other half-head. The composition is left on for 5 minutes and then rinsed out (water 38°C, flow rate 3 I/minute).

It is found that the red coloring is more uniformly distributed on the hair treated with composition B1 . On the other side of the half-head, the color is present, but non- uniformly (some areas colored, other areas not colored), and less intense.

It is also found that disentangling is easier for the side treated according to the in- vention.

The mini-head then underwent a cycle of 10 shampoo washes, each shampoo wash being followed by a step of rinsing and of drying with a hairdryer, before the next shampoo wash; the shampoo used is a commercial shampoo (DOP chamomile). After the 10 cycles of shampooing/rinsing/drying, it is found that the color, although attenuated, persists more intensely on the side treated according to the invention; for the other side, the color is almost no longer perceptible, but remains slightly pre- sent, although non-uniformly. The intensity is thus more pronounced when the pro- cess comprises step 2.

Color protection benefit is thus observed. Example 4 : comparative data

- Washing compositions AΊ and A’2 (weight % of AM)

^* To have the same quantity of coloring agent deposited on hair (0,093x3 = 0,279 and 0,026x3=0,078)

- Care composition B1 , as prepared in example 1

- Dye composition C1 , as prepared in example 1 a) Process according to the invention (AΊ + B1 + C1 )

Composition AΊ was applied to wet locks of hair (natural hair, 90% white, 20 cm long) in a proportion of 0.37 g of composition per gram of hair. Then, the locks were rinsed with water.

Further, composition B1 was applied to wet locks, in a proportion of 0.74 g of corn- position per gram of hair; after a leave-on time of 5 minutes, the locks were rinsed with water.

Then, composition C1 was applied to wet locks, in a proportion of 1 ,10 g of compo- sition per gram of hair; after a leave-on time of 5 minutes, the locks were rinsed with water and dried with a hairdryer. b) Comparative process (A’2 + B1 )

Composition A’2 was applied to wet locks of hair (natural hair, 90% white) in a pro- portion of 0.37 g of composition per gram of hair. Then, the locks were rinsed with water.

Further, composition B1 was applied to wet locks, in a proportion of 0.74 g of corn- position per gram of hair; after a leave-on time of 5 minutes, the locks were rinsed with water and dried with a hairdryer.

The coloration of the locks was measured in the CIE L^*a^*b^* system using a Konica Minolta CM-3600D spectrocolorimeter (specular mode included under illuminant D65, angle 10°).

According to this system, L^* indicates the lightness of the color of the hair. The lower the value of L^*, the more intense or darker the color of the hair.

Color uptake was evaluated by calculating the variation in color (DE) between the locks of untreated hair (hair before coloration) and the locks of dyed hair (after col- oration). The higher the value of DE, the better the color uptake.

The following results were obtained:

As shown by the L^* and DE values, locks treated with the process according to the invention exhibited significantly higher color uptake in dyeing and more intense color, in comparison with the locks treated with the comparative process.

As such, inventive process provided increased color uptake than comparative pro- cess; treatment of hair with inventive process provided a more intense coloration along the hair.
