Description

LIQUID COSMETIC COMPOSITION COMPRISING A HIGH CONTENT OF NON-VOLATILE OILS, NON-IONIC SILICONE SURFACTANT AND METHOD OF TREATING LIP

The subject of the present invention is a composition intended more particularly for makeup and / or care of the lips, which is represented in a liquid form and comprises at least 70% by weight of non-volatile oils, at least one mineral thickener, less than 1% by weight of a silicone nonionic surfactant, and solid particles, colored or otherwise. It also relates to a method implementing said composition of applying it on the lips.

Formulas for makeup and / or care of the lips have been known for a very long time and come in various forms, ranging from fluid formulas such as gloss, to solid compositions in the form of stick, supported or not, or compositions in pencil form.

In order to further diversify the compositions proposed to consumers, anhydrous or almost anhydrous formulas have appeared, even more fluid than gloss, and comprising high levels of oils, very comfortable to wear. However, these formulas are only available in unstained versions. This is mainly because it is very difficult to maintain high levels of suspended particles in this type oily medium, without losing the appeal of such compositions, which is precisely their great fluidity.

Indeed, with significant amounts of pigments, nacres or fillers, there is a sedimentation of these particles leading to the formation of a relatively unattractive cake, which may include clusters of particles. The cake thus formed has the additional disadvantage of being very cohesive. Thus, it can not be redispersed easily so as to find a homogeneous composition. Therefore, once the particles sedimented, the composition becomes almost unusable and no longer allows to obtain a uniform deposit on the lips, which is not acceptable.

Thus, to minimize the sedimentation problem, these compositions comprise relatively low levels of solid particles. But in this case, ranges of colors and renders color (in terms of coverage for example) accessible are limited. The compositions may also comprise dyes, thus soluble species in the medium where they are used. However, the number of dyes that can be used in this field is relatively small, which makes it difficult to extend the color ranges proposed or their intensity, whether or not the dyes are combined with colored solid particles.

We are therefore looking for makeup compositions and / or care of the lips, including high levels of non-volatile oils, which provide access to a wider range of hues and color effects (including coverage) without loss of a very fluid texture and which are still stable storage.

These and other objects are achieved by the present invention which therefore relates to liquid cosmetic compositions comprising: at least 70% by weight, relative to the weight of the composition, of at least one non-volatile oil or of a monophasic mixture of several non-volatile oils, the composition comprising at least one non-volatile hydrocarbon oil, polar or apolar; at least one mineral thickener; at least one silicone nonionic surfactant with a content of less than 1% by weight, relative to the weight of the composition; at least solid particles, colored or uncoloured.

It also relates to a process for makeup and / or care of the lips of applying such a composition.

The present invention therefore makes it possible to have storage-stable compositions which remain very fluid and may, however, contain higher levels of pigments, dyes and / or fillers than those envisaged in existing compositions of this type.

Thus, the composition makes it possible to obtain a deposit in larger ranges of hues, with more intense color effects.

The composition is furthermore easy to apply, and gives a homogeneous, comfortable, non-tacky, more covering deposit than the very fluid compositions existing. Other advantages of the present invention will emerge more clearly on reading the description and the examples that follow.

In the following, the wording "comprising a" or "comprising a" means "comprising at least one" or "comprising at least one" unless the opposite is specified. The expressions "at least one" and "several" are used interchangeably.

In addition, unless otherwise indicated, the indicated terminals for a domain are included in this field.

The composition according to the invention is in the form of a liquid at room temperature (25 ° C.) and atmospheric pressure (1.013 × 10 5 Pa)

More particularly, the viscosity of the composition varies between 0.2 and 0.8 Pa s, preferably between 0.3 and 0.7 Pa.s.

The measurement of the viscosity is generally carried out at 25 ° C., using a RHEOMAT RM 180 viscometer equipped with a mobile No. 2, the measurement being carried out after 10 minutes of rotation of the mobile within the composition ( time at the end of which there is a stabilization of the viscosity and the speed of rotation of the mobile) at 200 revolutions / min (rpm).

As previously stated, the composition does not sediment.

It is said that the composition does not sediment when it does not leave or appear little supernatant liquid after 48 hours of rest at 25 ° C, measured under the following conditions:

The measurements are made in a polyethylene terephthalate cylindrical container whose height is 46.9 mm and the radius of 15 mm, comprising two steel balls 6.35 mm in diameter, and provided with a plug.

The composition is introduced such that the height in the flask reaches 3.5 cm (which represents about 4.5 g of composition) and the flask is capped.

The latter is left for 48 hours at a temperature of 25 ° C. At the end of the 48 hours, the height of the supernatant liquid is measured.

It is considered that the composition is stable when the composition does not reveal any supernatant liquid.

NON-VOLATILE OILS

As indicated above, the composition according to the invention comprises at least 70% by weight, relative to the weight of the composition, of at least one non-volatile oil or of a monophasic mixture of several non-volatile oils.

Under these conditions, we speak of a stable monophasic mixture.

As indicated above, the composition comprises one or more non-volatile oils chosen from hydrocarbon, polar or apolar oils.

More particularly, the term "oil" means, within the meaning of the invention, non-aqueous compounds, liquid at 25 ° C and atmospheric pressure (1,013 .105 Pa), immiscible with water. By "immiscible" it is meant that mixing the same amount of water and oil, after mixing (eg Rayneri 550 rpm, 10 minutes) does not lead to a stable solution comprising only one phase under normal conditions of temperature and pressure.

The term "non-volatile oil" means an oil whose vapor pressure at 25 ° C. and atmospheric pressure is non-zero and less than 0.02 mmHg (2.66 Pa) and better still less than 10'3 mm. Hg (0.13 Pa).

By "hydrocarbon oil" is meant an oil formed essentially, or even constituted, of carbon and hydrogen atoms, and possibly of oxygen, nitrogen, and not containing a silicon atom or fluorine.

For the purposes of the present invention, the term "apolar oil" means an oil chosen from hydrocarbons, that is to say from compounds comprising only carbon and hydrogen atoms.

There may be mentioned, for example, the fumed silica which is preferably hydrophobic treated on the surface and whose particle size is more particularly less than 1 μm. In particular, it is possible to substitute silanol groups with hydrophobic groups: a hydrophobic silica is then obtained. The hydrophobic groups may be: trimethylsiloxyl groups, which are especially obtained by treatment of fumed silica in the presence of hexamethyldisilazane. Silicas thus treated are called "Silica silylate" according to the CTFA (6th edition, 1995).

The hydrophobic fumed silica has in particular a particle size ranging for example from 5 to 200 nm.

Silica aerogels are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air.

They are generally synthesized by sol-gel process in a liquid medium and then usually dried by extraction of a supercritical fluid, the most commonly used being supercritical CO2. This type of drying avoids the contraction of the pores and the material. The sol-gel process and the various dryings are described in detail in Brinker CJ, and Scherer G.W., Sol-Gel Science: New York: Academic Press, 1990.

The particles of hydrophobic silica aerogels that can be used have a specific surface per unit mass (Sm) ranging from 500 to 1500 m 2 / g, preferably from 600 to 1200 m 2 / g and better still from 600 to 800 m 2 / g, and size expressed in volume mean diameter (D [0.5]) ranging from 1 to 1500 μm, better still from 1 to 1000 μm, preferably from 1 to 100 μm, in particular from 1 to 30 μm, more preferably from 5 to 25 μm, more preferably 5 to 20 μm and even more preferably 5 to 15 μm.

The BET surface area corresponds to the total specific surface area of the particles under consideration.

The silica airgel particle sizes can be measured by static light scattering using a MasterSizer 2000 commercial particle size analyzer from Malvem. The data is processed on the basis of Mie scattering theory. This theory, which is accurate for isotropic particles, makes it possible to determine, in the case of non-spherical particles, an "effective" diameter of particles. This theory is particularly described in the work of Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

The packed density is determined by the ratio m / Vf, in this case 40 / Vf (Vf being expressed in cm3 and m in g) ·

According to a preferred embodiment, the particles of hydrophobic silica aerogels that can be used have a specific surface area per unit volume Sv ranging from 5 to 60 m / cm, preferably from 10 to 50 m / cm and better still from 15 to 40 m. / cm.

The specific surface area per unit volume is given by the relation: Sy = Sm x σ where σ is the packed density expressed in g / cm 3 and Sm is the specific surface per unit mass expressed in m2 / g, as defined above. .
