The invention also relates to a process for the cosmetic treatment of hair, comprising: the application to the hair of a cosmetic care composition comprising cationic polymers and organosilanes, followed or preceded by the application to said hair, a washing cosmetic composition comprising anionic surfactants, amphoteric and / or nonionic surfactants and fatty acids.

Description

The present invention relates to a cosmetic treatment method for the hair, comprising the sequential application, a cosmetic care composition comprising one or more cationic polymers and one or more organosilanes, and a washing cosmetic composition comprising, in addition to anionic surfactants and surfactants amphoteric and / or nonionic, one or more carboxylic acids comprising at least 8 carbon atoms.

The hair can be weakened or damaged by the action of external atmospheric agents such as light and bad weather, or by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perms and / or straightening.

To remedy these drawbacks, it is customary to use hair care which makes it possible to provide conditioning to the hair. These hair care compositions may be conditioning shampoos or conditioners which may be in the form of gels, hair lotions or more or less thick creams.

To improve the cosmetic properties of these compositions, it is known to introduce into the latter conditioning agents intended mainly for repairing or limiting the harmful or undesirable effects induced by the various treatments or attacks which undergo, more or less repeatedly, hair fibers.

For this purpose, it has already been proposed to use, inter alia, organosilanes in cosmetic care compositions, to give the hair satisfactory conditioning properties. Such compositions are for example described in patent applications FR2910276, EP2343042 and EP2111848. However, the care compositions described in these documents provide conditioning and disentangling properties which do not last long enough in time. Indeed, these properties generally do not resist washing enough and tend to decrease from the first shampoo. In other words, even if these hair care compositions make it possible to obtain suitable results during and just after their use (at T0), it has been found that these effects tend to disappear as the hair is washed; it was therefore necessary to regularly renew the application of hair care to maintain adequate conditioning effects.

It was then proposed by application WO2016 / 083578 a hair care composition for hair, capable of providing conditioning properties which are not only satisfactory but also persistent in washing, for example persistent after at least 3 shampoos. This care composition comprises the combination of organosilanes, cationic polymers of high charge density and cationic surfactants.

A composition is thus obtained which is capable of imparting to the hair a residual cosmetic treatment for shampoos, in particular softness, suppleness, smoothness, lightness, volume, and a natural, non-greasy and uncharged feel. This composition also provides the hair with an improved combability. These properties resist well to the various aggressions that the hair can undergo, such as light, bad weather, washing, perspiration. They are in particular persistent in shampoos, in particular after at least 3 shampoos.

However, it is still possible to improve the performance provided by the care compositions, in particular in terms of smoothing to the touch, flexibility and disentangling, both during the application of the composition to the hair, and then to the hair. rinsed, in particular to improve the remanence, that is to say the maintenance of the conditioning over a long period, during the following shampoos, in particular the remanence to at least 3 to 5 shampoos.

By performance, we mean in particular:

- cosmetic performance (smooth, flexible, detangling) when applying the treatment and

- long-term cosmetic performance (smooth, flexible, detangling) during the following shampoos.

The present invention therefore relates to a method of cosmetic treatment of hair, comprising:

a step (i) of applying to said hair a cosmetic care composition comprising one or more cationic polymers and one or more organosilanes, and

- a step (ii) of applying to said hair, a cleansing cosmetic composition, comprising:

- one or more carboxylic acids comprising at least 8 carbon atoms,

one or more anionic surfactants different from said carboxylic acids comprising at least 8 carbon atoms, and

- one or more surfactants chosen from amphoteric surfactants and nonionic surfactants, and mixtures thereof.

Step (i) can be followed or preceded by step (ii).

The present invention also relates to the use of a washing cosmetic composition, comprising

- one or more carboxylic acids comprising at least 8 carbon atoms,

one or more anionic surfactants different from said carboxylic acids comprising at least 8 carbon atoms, and

- one or more surfactants chosen from amphoteric surfactants and nonionic surfactants, and mixtures thereof;

in combination with a cosmetic care composition comprising one or more cationic polymers and one or more organosilanes, for obtaining a residual treatment, in particular of flexibility, smoothing to the touch and / or disentangling, residual, in particular with at least 3 shampoos .

The implementation of the invention makes it possible in particular to obtain, from the application, the desired properties and in particular flexibility, smoothness in particular to the touch and visual, as well as an improved disentangling.

The cosmetic treatment method according to the invention therefore comprises a step consisting in the application to the hair of a cosmetic care composition as defined below.

This step may or may not be followed by an installation step, for example an exposure time of 1 to 15 minutes, in particular 2 to 5 minutes; it can also be followed by a rinsing step, or not, for example with water; and / or a drying step. Preferably, said application step is followed by a step for applying the composition, preferably for 1 to 15 minutes, with rinsing and drying.

A standard shampoo is applied to strands of sensitized hair (SA20) at the rate of 0.4 g of shampoo per g of hair. The locks are then rinsed and dried with a hair dryer.

The above care composition is then applied to the locks, at a rate of 0.4 g per g of hair. The locks are then rinsed and dried in a hair dryer.

2 / step 2

The cosmetic performance obtained after several shampoos is then compared, using different shampoo compositions.

For the study of long-term effects, the formulas are evaluated on medium-dry hair, then the dried locks and the shampoo reapplied in order to mimic the frequency of shampoos of a consumer.

We therefore carry out for each shampoo tested several cycles of application / rinsing / drying on wick. At each cycle, the cosmetic performance on wet hair (rinsed) is evaluated. 6 shampoo / dry cycles are carried out.

The criteria evaluated are smoothing to the touch, suppleness and detangling on damp hair.

The locks are evaluated blindly, by a panel of 3 experts who give a score of 1 to 5 for each criterion, in steps of 1 (1 = very bad, 2 = bad, 3 = average, 4 = good, 5 = very good).

The score indicated below (overall cosmetic performance score) corresponds to the average of the 3 criteria and 3 experts (average of the 9 scores).

Evaluation :

The shampoo according to the invention and a reference shampoo (ColorVive - Elsève) are applied, by half-head, to 6 models with long and sensitized hair (sensitization of 3 or more). About 8 g of shampoo is applied per demitête.

The hair is then rinsed off and the above care composition is applied to the whole of the hair at the rate of 8 g per half head. The hair is then rinsed and an expert blindly assesses the cosmetic criteria used, during the application of the treatment, then on damp hair and on dry hair.

For each criterion, the expert assigns a score from 1 to 5, in steps of 1 (1 = very bad, 2 = bad, 3 = average, 4 = good, 5 = very good).

The note indicated below corresponds to the average of the 6 models.

The following results are obtained (average of the 6 scores):

Reference shampoo then care Invention shampoo then care Flexibility when applying the treatment 3.3 4.2 Smooth touch when applying the treatment 3.3 4.1 Detangling damp hair 3.9 4.5 Smooth touch damp hair 3.4 4.2 Smooth visually dried hair 3.3 3.8

The shampoo according to the invention followed by the application of the care according to the invention leads to performances in terms of flexibility, smoothness to the touch and visual, and disentangling, improved compared to a process comprising the application of a classic shampoo followed by the application of a treatment according to the invention.
