Description

Process for treating keratin fibers using a functionalized acrylate polymer and an alkoxysilane

Technical field of the invention

The present invention relates to a method for treating keratin fibers comprising the application to the keratin fibers of an acrylate functionalized polymer and an alkoxysilane.

Background of the invention

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

The hair is thus damaged by these different factors and can in the long run become dry, rough, brittle or dull.

Thus, to remedy these drawbacks, it is usual to have recourse to hair care products which use compositions intended to condition the hair in a suitable manner by providing it with satisfactory cosmetic properties, in particular smoothing, shine, softness, suppleness, lightness, a natural feel and good detangling properties. The purpose of these compositions is therefore to protect, repair and cosmetically transform the hair in a lasting manner.

These hair care compositions, intended to be applied regularly to the hair, can be, for example, conditioner shampoos, conditioners, masks or serums, and can be in the form of gels, hair lotions and more or less thick care creams.

However, such compositions still too often lead to effects which are not sufficiently durable and which fade in particular upon washing.

Moreover, in the field of dyeing keratin fibres, in particular human fibres, it is already known to dye keratin fibers by various techniques using in particular direct dyes for non-permanent dyes or dye precursors for permanent dyes.

Direct dyeing consists of dyeing keratin fibers with dye compositions containing direct dyes. These dyes are colored and coloring molecules with an affinity for keratin fibres. They are applied to the keratin fibers for the time necessary to obtain the desired coloration, then rinsed off.

The conventional dyes which are used are in particular dyes of the nitrobenzene, anthraquinone, nitropyridine, azo, xanthene, acridine, azine, triarylmethane type or natural dyes.

Some of these dyes can be used under lightening conditions, which makes it possible to obtain visible colorations on dark hair.

Another non-permanent coloring method is to use pigments. Indeed, the use of pigment on the surface of keratin fibers generally makes it possible to obtain visible colorings on dark hair since the pigment on the surface masks the natural color of the fiber. The use of pigment for coloring keratin fibers is for example described in patent application FR 2 741 530, which recommends the use for the temporary coloring of keratin fibers of a composition comprising at least one dispersion of particles of film-forming polymer comprising at least one acid function and at least one pigment dispersed in the continuous phase of said dispersion.

Non-permanent colorations based on direct dyes and/or pigments can have the disadvantage of having low resistance to water and/or shampoos as well as to external agents such as sebum, perspiration, actions mechanical such as brushing and/or rubbing. The colorations obtained can also generate staining and/or transfer, in particular when the fibers are wet. In addition, the shampoo protocol may vary from one user to another, in particular with regard to the length of the shampoo's leave-in time, a longer leave-in time possibly being the cause of poorer hold. from coloring to shampoo.

In addition, non-permanent hair coloring compositions can also lead to an unnatural and/or non-cosmetic feel to the hair, the hair thus colored possibly lacking in softness and/or suppleness and/or individualization in particular.

Furthermore, the selectivity of the coloration obtained by this type of process can sometimes be significant, that is to say that sometimes significant differences in coloration can be observed throughout the same keratin fiber which generally comprises differently sensitized areas from its root to the tip.

There is therefore a real need to develop a process for treating keratin fibers which makes it possible to condition the keratin fibers in a satisfactory manner, in particular by improving dry or wet disentangling and softness to the touch, and this in a durable manner, in particular after several shampoos such as 7 shampoos. Such a process should not lead to degradation of the keratin fibers and make it possible to preserve perfectly individualized keratin fibers.

There is also a real need to develop a process for coloring keratin fibers which makes it possible to obtain a satisfactory coloring and having a better remanence to shampoos, the remanence being independent of the shampoo protocol followed by the user and being observed in particular for long exposure times of the shampoo, i.e. at least one minute. Such a process should also make it possible to obtain a coloring with low selectivity, that is to say low differences in coloring observed throughout the same keratin fiber which generally comprises zones sensitized differently from its root to The point.

The applicant has discovered, surprisingly, that all or part of these objectives can be achieved by the process according to the present invention.
