Description

The present invention relates to a cosmetic composition, in particular a capillary composition, comprising one or more fatty-chain silanes and one or more propellants. The subject of the present invention is also the use of said composition for shaping and / or fixing keratin fibers, such as human keratinous fibers and in particular the hair, as well as a process for the cosmetic treatment of keratinous fibers. using such a composition.

Within the meaning of the present invention, the term "hair cosmetic composition", hair fixing and / or maintenance compositions, hair care compositions, hair conditioning compositions, such as compositions intended to provide hair, the softness to the hair or hair makeup compositions.

When a cosmetic composition is applied to the hair for a particular treatment, it sometimes happens that the composition leads to a dry touch of the hair. This is the case for example styling products and especially lacquers. Hair styling products are usually used to build, structure the hairstyle and give it a lasting hold. They are usually in the form of lotions, gels, mousses, creams, sprays, etc. The corresponding compositions generally comprise one or more fixing polymers in a cosmetically acceptable medium. These polymers allow the formation of a sheathing film on the hair, thus ensuring the maintenance of the hairstyle. However, the presence of these fixing polymers generally causes a dry touch to the hair, before or after disentangling, which can cause a perception of hair damaged by these styling products. In the case of skincare products, the cosmetic agents are often fats that bring a touch and a bold visual to the hair. The product transfers into the hands and can also give a dirty hair feel.

There is therefore a need for compositions that make it possible to obtain a satisfactory cosmetic feel for the hair. In particular, in the case of styling products, there is a need for compositions which make it possible to obtain a satisfactory cosmetic feel while providing hair support.

From the international patent application VVO 2004/012691 is known the cosmetic use of silanes for the improvement of the condition of the hair.

The patent application EP 0 159 628 proposes compositions for strengthening the elasticity of the hair, comprising an alkyltrialkoxysilane. Furthermore, the patent application EP 1 736 139 describes a hair treatment composition comprising an alkoxysilane, an organic acid and water, the pH of the composition being between 2 and 5. Finally, the patent application EP No. 0 877 027 discloses a composition comprising an organosilane and a particular polyol. Because of their high reactivity, silanes sometimes have performance heterogeneity problems, which may be thought to be related to distribution problems. The Applicant has now discovered that, surprisingly, a particular silane with a fatty chain in a pressurized composition makes it possible to provide an improved cosmetic feel to the hair with a good regularity of result throughout the hair.

In addition, the combination of a particular fatty-chain silane with at least one fixing polymer in a pressurized composition makes it possible to provide an improved cosmetic feel while providing a strong fixation of the hair. In particular, such a composition makes it possible, on the one hand, to confer good fixation on the hair, and on the other hand, to give the hair a natural and soft feel, and a smooth feel after disentangling. The subject of the present invention is therefore a cosmetic composition comprising: one or more fatty-chain silanes of formula (I) below and / or their oligomers: Si (OR 2), (R 3) x (OH) y (I) I) in which - R 1 represents a linear or branched alkyl or alkenyl group comprising from 7 to 18 carbon atoms, - R 2 and R 3, which may be identical or different, represent a linear or branched alkyl group comprising from 1 to 6 carbon atoms, carbon, - y denotes an integer ranging from 0 to 3, - z denotes an integer ranging from 0 to 3, and - x denotes an integer ranging from 0 to 2, - with z + x + y = 3, - one or more propellants.

Another subject of the invention consists of a cosmetic composition that can be obtained from one or more propellants and one or more compounds of formula (I) and / or their oligomers. This particular combination makes it possible to bring a natural and soft touch to the fibers. It also gives a smooth, natural and soft feel to the fibers after disentangling. These results are homogeneous over the entire area of application. Another subject of the invention consists of a process for the cosmetic treatment of hair using a composition according to the invention.
