Description

Composition comprising a fixing polymer, a cationic polymer, an organosilane, a nonionic polysaccharide and a wax

The present invention relates to a hair cosmetic composition comprising one or more fixing polymers, one or more cationic polymers different from the one or more fixing polymers, one or more organosilanes, one or more nonionic polysaccharides and one or more waxes. The invention also relates to the use of the hair cosmetic composition according to the invention for shaping and / or conditioning keratinous fibers, in particular human keratinous fibers such as the hair.

Hair styling products are usually used to build, structure the hairstyle and bring him an outfit. They are usually in the form of lotions, gels, mousses, creams, sprays, etc. These compositions generally comprise one or more film-forming polymers or "fixing polymers". These polymers allow the formation of a sheathing film on the hair, thus ensuring the maintenance of the hairstyle.

These compositions may be in the form of gels or hair mousse which are generally applied to wet hair which is shaped before blow drying or drying.

To obtain a satisfactory fixing power, it is known to incorporate in the styling products polymers with a very high fixing power, and / or to increase the concentration of fixing polymer. However, the use of such extremely fixative products causes a number of disadvantages. In particular these products can lead to a dry and rough touch of the hair.

In addition, if these products make it possible to secure the fixation, however, they tend to freeze the hairstyle, in particular by providing a "helmet effect". This effect is often poorly perceived by users.

Moreover, these products do not generally give full satisfaction in terms of persistence to different external agents (eg shampoos, light, pollution).

There is therefore a real need to develop cosmetic hair compositions to obtain a sustainable maintenance of the hairstyle, with styling effects persisting all day or even days, while maintaining a natural and not frozen to the hairstyle, and providing a pleasant, consistent and consistent cosmetic feel, including a smooth, soft feel and beautiful hair discipline.

However, the Applicant has now surprisingly discovered that a composition comprising the combination of one or more fixing polymers, with one or more cationic polymers different from the fixing polymer or polymers i), one or more organosilanes, and one or more nonionic polysaccharides, solved the problems mentioned above.

The present invention therefore relates to a hair cosmetic composition, comprising: i) one or more fixing polymers, ii) one or more cationic polymers different from the fixing polymer or polymers i), iii) one or more organosilanes, and iv) one or more several nonionic polysaccharides, and v) one or more waxes.

The Applicant has notably found that the composition according to the invention makes it possible in particular to obtain an ease of shaping keratinous fibers, that is to say a good resistance of the hair over time both in wet and dry conditions. , while bringing volume to the hair, and without freezing the hairstyle.

In particular, it also provides a particularly soft and pleasant touch of the hair.

The Applicant has also found that the implementation of the composition according to the invention on keratin fibers such as the hair, allows a homogeneous and regular deposition thereof.

In particular, it has also been found that the composition according to the invention facilitates the disentangling of damp hair, provides body and texture to dried hair, and leads, on curly hair, to loops having a good definition, with tonicity (rebound).

Furthermore, the use of the composition according to the invention makes it possible to improve the remanence of the shaping of the keratinous fibers (or of the conditioning properties); the shaping, discipline, anti-frizz and conditioning properties may especially be persistent to at least one shampoo, in particular to at least 2 shampoos, better to at least 3 shampoos, or even at least 4 shampoos.

The particularly persistent conditioning properties are in particular the soft touch on dried hair, and / or the easy disentangling of keratinous fibers. Other objects, features, aspects and advantages of the invention will emerge even more clearly on reading the description and the example which follows.

In the present description, the term "at least one" is equivalent to the term "one or more" and may be substituted therefor; the expression "included between" is equivalent to and may be substituted for the phrase "ranging from", and implies that the boundaries are included.

The fumed silicas can be obtained by high temperature hydrolysis of a volatile silicon compound in an oxyhydrogen flame, producing a finely divided silica. This process makes it possible in particular to obtain hydrophilic silicas which have a large number of silanol groups on their surface.

In particular, among the hydrophobic silicas, mention may be made of silica aerogels. Aerogels are ultra-light porous materials, the first of which were made by Kristler in 1932. They are generally synthesized by a sol-gel process in a liquid medium and then dried by extraction of a supercritical fluid. The most commonly used supercritical fluid is supercritical CO2. This type of drying avoids the contraction of the pores and the material. Other types of drying also make it possible to obtain porous materials from gel, namely (i) drying by freeze drying, consisting of solidifying at low temperature the gel and then subliming the solvent and (ii) drying by evaporation . The materials thus obtained are called cryogels and xerogels respectively.

The absorption capacity measured at Wet Point, and denoted by Wp, corresponds to the amount of oil that must be added to 100 g of particles in order to obtain a homogeneous paste. It is measured according to the so-called Wet Point method or method for determining the setting of powder oil according to the principle described in standard NF T 30-022. It corresponds to the quantity of oil adsorbed on the available surface of the powder and / or absorbed by the powder by measuring the Wet Point, described below: a quantity m = 2 g of powder is placed on a glass plate and then the oil (isononyl isononanoate) is added dropwise. After addition of 4 to 5 drops of oil in the powder, mixing is carried out with a spatula and oil is added until the formation of oil and powder conglomerates. From this moment, the oil is added one drop at a time and then triturated with the spatula. The addition of oil is stopped when a firm and smooth paste is obtained. This paste should be spread on the glass plate without cracks or lumps. The volume Vs (expressed in ml) of oil used is then noted. The oil intake corresponds to the ratio Vs / m.

This theory, which is accurate for isotropic particles, makes it possible to determine, in the case of non-spherical particles, an "effective" diameter of particles. This theory is particularly described in the work of Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

The subject of the present invention is also a process for shaping and / or conditioning keratinous fibers, in particular human keratinous fibers such as the hair, comprising at least one step of applying to said fibers a composition such as previously described.

This or these steps of application of the composition according to the invention may optionally be preceded by at least one step of washing said fibers with a shampoo, and optionally followed by at least one rinsing step with the water of said fibers.

Moreover, this or these steps of application of the composition according to the invention may optionally be followed by a laying step, for example a laying time of 1 to 15 minutes; in particular 2 to 5 minutes; then followed by a rinsing step, or not, for example with water; and / or a drying step.

Preferably, the keratin fibers are not rinsed after the step or steps of application of the composition according to the invention. By "are not rinsed" is meant that no rinsing step of the keratinous fibers is carried out at least 30 minutes, preferably 1 hour, after the step of applying the composition according to the invention.

The present invention also relates to a use of the composition as described above, for the shaping and / or conditioning of keratinous fibers, in particular human keratin fibers such as the hair.

Preferably, the composition as described above is used for styling the hair.

The following examples serve to illustrate the invention without being limiting in nature.

Example

An example of composition according to the invention was prepared from the following ingredients whose contents are indicated in the tables below (in g of raw materials as they are).

Comparative tests

Volume control / anti-squat

Two wicks A and B of natural curly hair of 2.7g were previously washed with a standard shampoo at the rate of 0.4g of shampoo per g of hair.

After rinsing, the wick A is treated with the composition described above at a rate of 0.15 g of composition per g of hair, followed by brushing with a brush until complete drying.

After rinsing, the wick B is directly subjected to a brushing with a brush until complete drying.

There is a better control of the volume of the hair, in particular no frizz, for the wick A with respect to the wick B.

Each of the locks is then subjected to a test of 1 to 3 repeated shampoos, each shampooing step being followed by drying in the open air.

We note that the superiority of performance in terms of discipline of lock A persists after 1 and 3 shampoos

Disciplined

The locks A and B treated as described above are photographed at each stage of the protocols described above. The orientation of the fibers with respect to the vertical axis is determined by image analysis, thus making it possible to quantify their average degree of alignment Θ (expressed in degrees): the lower the value of Θ, the better the alignment So better is the performance in terms of discipline.

The wick A treated with the composition according to the invention has a better alignment of the fibers, both before the shampooing test and after 1 and 3 repeated shampoos, compared with the wick B: the performance of discipline is better and residual for wick A.

Conditioning

Two locks A 'and B' of natural hair of lg were previously washed with a standard shampoo at the rate of 0.4g of shampoo per g of hair.

After rinsing, the wick A 'is treated with the composition described above at a rate of 0.15 g of composition per g of hair. After rinsing, the wick B 'is not treated. The surface condition of the locks was evaluated by the method described below on damp hair on the one hand, and then on dry hair on the other hand (after complete drying in an oven).

The wick A 'or B' is attached to a force sensor and then moved vertically between two cylindrical rubbers. The force necessary for the displacement of the wick is then recorded: the lower the force, the easier the displacement, which is representative of a smoother and homogeneous surface state.

The average force obtained with the wick A 'is significantly lower than that obtained with the wick B': the surface state of the wick A 'treated with the composition according to the invention has a smoother and homogeneous surface state than the wick B '.
