SPINABLE MATERIAL, COSMETIC COMPOSITION
SPINNING, MAKE-UP COMPOSITION AND PROCESS FOR
MAKEUP
The present invention relates to a spinnable material, to a cosmetic composition comprising this spinnable material, and to a process for making up keratin materials using the cosmetic composition.

consistant, modelable et présentant un caractère filant qui puisse être 1 étalé puis étiré à la main ou à l'aide d'instruments habituellement utilisés, comme une brosse, un peigne, une spatule ou un couteau. In cosmetics, in particular for making up keratin materials such as the skin, hair, nails, eyelashes and eyebrows, lips and any other area of the body and face, and in decoration, it is advantageous to have a sufficiently material

consistent, moldable and having a stringy character which can be spread and then stretched by hand or with the aid of commonly used instruments, such as a brush, comb, spatula or knife.

We are trying to obtain threads which, after stretching, are sufficiently consistent, that is to say that they must retain their shape, neither retract nor sag under the action of their own weight, for example. in the case of stage make-up, hair or eyelashes.

A rapid increase in the consistency of the material after its application can be obtained by changing from the liquid state to the solid state by cooling, but the implementation is difficult in the field of cosmetics.

Indeed, this change of state requires heating of the material at the time of its use and a melting temperature above ambient temperature while remaining sufficiently low to avoid any risk of burning or of a burning sensation during its application.

To increase the consistency, it is also possible to use one or more chemical substances which are solid at room temperature, dispersed,

<Desc / Clms Page number 2>

solubilized or swollen by volatile solvents. As these solvents then evaporate, there is an increase in the concentration of solid chemicals. A sufficient increase in consistency can then be obtained.

This use of organic solvents has a drawback owing to the fact that it is necessary to have recourse to harmless solvents, and in cosmetics the preferred solvent is water, but it is not very volatile at room temperature.

Furthermore, the materials which may have a known spinning character are more or less gelled solutions of surfactants, molten polymers, gels, sol-gels and derivatives of petroleum products such as carbon fibers, but they have drawbacks. such as lack of consistency and breakage of the yarns, the need for a high deformation rate, a high temperature, a thermal shock to spin and then set the yarns obtained or a fiber stabilization treatment.

The Applicant has surprisingly found that certain materials comprising a certain organization of phases were consistent and moldable at room temperature, and made it possible to form threads by simple stretching by hand or using an instrument such as a brush. , comb, spatula or knife.

These spinnable materials comprise, at room temperature, 1) at least one mesomorphic phase of direct hexagonal or fluid lamellar type, and 2) at least one crystalline or amorphous solid phase, and / or one mesomorphic phase of cubic or lamellar gel type.

By "room temperature" is meant a temperature of about 25 ° C.

The consistency of these spinnable materials is evaluated by measuring the rheological properties in oscillation mode in their linear viscoelastic domain. They then have a complex modulus G * of between 102 and 106 Pa, preferably between 103 and 105 Pa, and a loss angle 8 of between 0 and 45, preferably

<Desc / Clms Page number 3>

between 10 and 40, at 25 C and for frequencies ranging from 10-2 Hz to 1 Hz.

In addition, in cosmetics, after application to the hair, eyelashes or eyebrows, the spinnable material has the advantage of not adhering either to itself or to other surfaces and it can be easily removed by washing with water or by using a cleansing product such as a lotion based on a solution of surfactants.

The subject of the present invention is therefore a spinnable material comprising, at room temperature, at least one mesomorphic phase of direct hexagonal or fluid lamellar type, and at least one crystalline or amorphous solid phase, and / or one mesomorphic phase of cubic or lamellar type. gel, and exhibiting in oscillation mode in its linear viscoelastic domain, a complex modulus G * of between 102 and 106 Pa, preferably between 103 and 105 Pa, and a loss angle 5 of between 0 and 45, preferably between 10 and 40, at 25 C and for frequencies ranging from 10-2 Hz to 1 Hz.

Another object of the invention consists of a spinnable cosmetic composition comprising said spinnable material.

A subject of the present invention is also a makeup composition.

A subject of the present invention is also a process for making up keratin materials using the spinnable cosmetic composition.

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

The present invention relates to a spinnable material comprising, at room temperature,
1) at least one mesomorphic phase of fluid lamellar type or direct hexagonal, and
2) at least one crystalline solid phase, an amorphous solid and / or a mesomorphic phase of the gel or cubic lamellar type.

<Desc / Clms Page number 4>

Brown) means a liquid crystal phase with plane symmetry, e comprising several bilayers of amphiphilic compounds arranged in parallel and separated by a liquid medium which is generally water.

GH Brown) is meant a liquid crystal phase with a hexagonal arrangement of parallel cylinders consisting of 'an amphiphilic compound and separated by a liquid medium which is usually water.

By cubic phase is meant a phase organized in a bipolar manner into distinct hydrophilic and lipophilic domains, in close contact and forming a three-dimensional network with cubic symmetry. Such an organization has been described in particular in "La Recherche", Vol.

23, pages 306-315, March 1992 and in "Lipid Technology", Vol. 2, No. 2, pages 42-45, April 1990. Depending on the arrangement of the hydrophilic and lipophilic domains, the cubic phase is said to be of normal or inverse type. The term cubic phase used according to the present invention groups together the different types of cubic phase.

The term “gel lamellar phase or Lp phase” is understood to mean a phase in which the molecules of surfactants and / or more generally of amphiphilic compounds are organized in the form of bimolecular layers spaced apart by aqueous layers. Within the bimolecular layers, the molecules are distributed according to a hexagonal geometry and their hydrocarbon chains are in a crystalline state, they are oriented perpendicular to the plane of the bimolecular layers but have no specific orientation with respect to each other in the plan of these layers (Handbook of lipid research 4, the physical chemistry of lipids from alkanes to phospholipids, DM Small Editor, 1986, Plenum Press, p. 51-56).
