Description

AEROSOL COMPOSITION COMPRISING A FIXING POLYMER AND A LAMELLAR PARTICULATE MATERIAL, A PROCESS AND A DEVICE

The present invention relates to a composition comprising one or more fixing polymers, one or more lamellar particulate materials, one or more organic solvents and one or more propellants.

The invention also relates to a process for treating keratin fibres, comprising at least one step of applying the composition according to the invention to said keratin fibres, and also to an aerosol device comprising such a composition.

Styling products are normally used to construct and structure the hairstyle and to give it hold. They are usually in the form of lotions, gels, mousses, creams, sprays, etc. These compositions generally comprise one or more fixing polymers. These polymers allow the formation of a coating film on the hair, and/or the formation of micro-bonds between the individual hairs, thus ensuring the hairstyle hold.

These compositions are subjected to several stress factors, for example heat, humidity, rain or sebum, and repeated mild mechanical stress factors, which bring about a loss of fixing of the hairstyle after only a few hours.

Moreover, these compositions are not always entirely satisfactory in terms of hairstyle hold. It has in particular been found with these compositions that the hairstyle collapses after 3 to 4 hours of exposure to stress factors.

Furthermore, these compositions also have a certain number of drawbacks. These compositions generally lead to a dry feel, a dull and coarse appearance of the hair, and have a tendency to solidify the hairstyle, especially giving a "helmet effect". This effect is often poorly perceived by users.

To increase the durability of the initial fixing of the hairstyle (i.e. the hold of the initial shaping of the hairstyle), it is known practice to incorporate into styling products fibres such as silk or viscose fibres. However, the use of fibres does not afford a pleasant feel and has the drawback of rapidly clogging the diffuser valves.

There is thus a real need to develop compositions which are capable of giving the hairstyle good resistance to deformation and long-lasting fixing, to minimize the supply of residues, and which have styling effects such as giving the hair body and volume, which can persist throughout the day, while at the same time conserving a natural and non- solidified appearance for the head of hair, and affording satisfactory cosmetic properties, in particular a pleasant cosmetic feel, especially a soft and smooth feel.

It is also desired for these compositions to be less expensive to manufacture, especially by reducing the concentration of fixing polymer(s), while at the same time conserving their properties.

These objectives are achieved by the present invention, the subject of which is especially an anhydrous composition comprising:

one or more fixing polymers chosen from anionic fixing polymers, amphoteric fixing polymers, and mixtures thereof;

- one or more lamellar particulate materials;

one or more organic solvents; and

one or more propellants.

It has thus been found that the composition according to the invention has good styling properties. It makes it possible especially to obtain good resistance to deformation and also good hold of the head of hair over time, in particular for more than 4 hours.

It has also been found that the composition according to the invention gives the head of hair volume, especially after disentangling, and does so without further solidifying the hairstyle.

It also gives the hair a particularly soft and pleasant feel.

Moreover, it has also been found by the Applicant, surprisingly, that when the composition according to the invention is packaged in an aerosol device comprising a spray valve, the dispensing of the composition is facilitated and there is less risk of said valve being clogged, especially in the case of a high concentration of lamellar particulate materials, when compared with the styling products of the prior art.

The compositions according to the invention also have the advantage of having a moderate manufacturing cost while at the same time having satisfactory fixing and cosmetic properties.

Another subject of the present invention relates to a process for treating keratin fibres, in particular human keratin fibres such as the hair, comprising at least one step of applying a composition according to the invention to said keratin fibres. A subject of the present invention is also an aerosol device comprising a composition according to the invention.

Other characteristics, aspects, subjects and advantages of the present invention will emerge even more clearly on reading the description and the examples that follow.

For the purposes of the invention, unless otherwise indicated:

the limits of a range of values are included in that range, in particular in the expressions "between... and ..." and "ranging from ... to ...";

- the expression "at least one" used in the present description is equivalent to the expression "one or more", and may be substituted therefor;

According to the present patent application, the term "keratin fibres" denotes human keratin fibres and more particularly the hair.

The fixing polymers

The composition according to the invention comprises one or more fixing polymers chosen from anionic fixing polymers, amphoteric fixing polymers, and mixtures thereof.

For the purposes of the present invention, the term "fixing polymer" means a polymer for fixing the shaping of keratin fibres, in particular of the hair.
