COMPOSITION IN THE FORM OF AN INVERSE EMULSION COMPRISING A FATTY LIQUID BODY, A SILICONE SURFACTANT, AN ORGANOSILANE AND A CATIONIC POLYMER.

(© The present invention relates to a composition in the form of a reverse emulsion comprising at least one fatty substance liquid at ambient temperature and at atmospheric pressure, at least one silicone surfactant, at least one organosilane, and at least one cationic polymer.

The present invention also relates to a process for treating keratin fibers, in particular human keratin fibers such as the hair, using said composition.

Composition in the form of a reverse emulsion comprising a liquid fatty substance, a silicone surfactant, an organosilane and a cationic polymer

The present invention relates to a composition in the form of a reverse emulsion comprising at least one fatty substance which is liquid at ambient temperature and at atmospheric pressure, at least one silicone surfactant, at least one organosilane, and at least one cationic polymer.

The present invention also relates to a process for treating keratin fibers, in particular human keratin fibers such as the hair, using said composition.

The present invention finally relates to the use of said composition for conditioning keratin fibers, in particular human keratin fibers such as the hair.

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

Thus, to remedy these drawbacks, it is now customary to use hair care implying the use of care compositions which make it possible to condition the hair following these treatments in order to give them in particular shine, softness, suppleness, lightness, a natural touch as well as disentangling properties.

These hair care compositions may for example be conditioning shampoos or compositions to be applied before or after the shampoos, and 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 cosmetic agents known as conditioning agents intended mainly for repairing or limiting the harmful or undesirable effects induced by the various treatments or aggressions which undergo, more or less less repeated, the hair fibers. These conditioning agents can of course also improve the cosmetic behavior of natural hair.

For this purpose, it has already been proposed to use cosmetically active organic compounds such as cationic polymers and organic silicon compounds (or organosilanes) as conditioning agents, in cosmetic care compositions, such as after -shampoos, to give the hair satisfactory conditioning properties.

Such compositions are for example described in patent applications FR 2 910 276, EP 2 343 042 and EP 2 111 848.

However, the conditioning and disentangling properties conferred by the care compositions described in the prior art remain insufficient and do not last long enough in time. Indeed, these properties do not generally resist washing enough and tend to fade from the first shampoo.

However, consumers are more and more in search of treatment compositions which are not only capable of conditioning the hair in a suitable manner, and whose effects are visible throughout the day, but also after one or even several shampoos. .

Furthermore, these compositions change appreciably over time under normal storage conditions, in particular in terms of their viscosity and their visual appearance.

This results in a cloudy visual appearance and / or an unsatisfactory texture of the compositions, as well as lower efficiency.

On the other hand, it is often difficult to obtain stable compositions of satisfactory viscosity when it is desired to introduce large quantities of organosilanes and / or cationic polymers therein.

Thus, there is a real need to provide a composition for conditioning keratin fibers, in particular human keratin fibers such as the hair, which does not have the drawbacks mentioned above, that is to say which not only remains stable over time, with a satisfactory viscosity, but which is also capable of providing conditioning properties which are not only satisfactory but also persistent in washing, for example persistent after at least 3 shampoos.

The Applicant has surprisingly discovered that a composition in the form of a reverse emulsion (or water-in-oil emulsion) comprising one or more liquid fatty substances, one or more silicone surfactants, one or more organosilanes and one or more cationic polymers, made it possible to achieve the objectives set out above.

The subject of the present invention is in particular a composition in the form of a water-in-oil emulsion comprising:

- one or more fatty substances which are liquid at room temperature and at atmospheric pressure,

- one or more silicone surfactants,

- one or more organosilanes other than silicone surfactants,

- one or more cationic polymers, and

- some water.

The present invention also relates to a process for treating keratin fibers, in particular human keratin fibers such as the hair, consisting in applying to said keratin fibers, a composition as defined above.

In addition, the present invention also relates to the use of a composition as defined above for the conditioning of keratin fibers, in particular human keratin fibers such as the hair.

The composition according to the invention provides particularly satisfactory conditioning properties for the hair, and in particular gives them good sheathing, softness, suppleness, straightening, lightness and volume. This composition also provides the hair with an improved combability.

Furthermore, the properties provided by the composition according to the invention 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.

The composition according to the invention is also particularly stable over time.

By “stable” in the sense of the present invention, it is meant that the visual appearance and the viscosity of these compositions do not change, or not substantially change (variation generally less than 10% relative to the viscosity at T0), during time under standard storage conditions, for example during the month or two months following their manufacture, at ambient temperature or at a temperature equal to 45 ° C.

For the compositions according to the invention, no phase shift or any precipitation is observed over time, and the viscosity does not change, even when they contain large amounts of cationic polymers and / or organosilanes. In addition, if the composition is initially transparent or clear, it retains this transparency over time.

Other objects, characteristics, aspects and advantages of the invention will appear even more clearly on reading the description and the examples which follow.

In what follows, and unless otherwise indicated, the limits of a domain of values are included in this domain, in particular in the expressions "included between" and "going from ... to ...".

Furthermore, the expressions “at least one”, “at least two”, and “at least” used in the present description are respectively equivalent to the expressions “one or more”, “two or more” and “greater than or equal”.
