Technical Field

The present invention relates to the field of cosmetics and in particular to the field of compositions in the form of visible droplets suspended in a liquid.

Background

There are two-phase compositions currently on the market which are attractive to consumers due to their aesthetic properties. These compositions consist of two mutually immiscible phases which are mixed together temporarily by shaking before use.

Pickering emulsions (Pickering emulsions) have attracted great consumer interest due to their aesthetic and surfactant-free properties and are widely used in cosmetic products. To form a pickering emulsion, finely divided solid particles are adsorbed at the interface between the oil and the homogeneous mixture and serve to stabilize the oil droplets.

However, these emulsions tend to become unstable over time upon storage. The reason for this is that sedimentation or even phase separation of the solid particles is observed, resulting in an unappealing appearance to the consumer.

FR1160798 discloses a composition comprising a nonpolar hydrocarbon-based oil, C₁-C₄Pickering emulsions of monohydric alcohols and hydrophobic silica aerogel particles.

Higher amounts of alcohol are necessary to stabilize the visibly dispersed oil phase in the aqueous phase. However, it may cause discomfort to the consumer. Furthermore, it is not a problem in said document that the pickering emulsion comprises visible oil droplets dispersed in an aqueous phase.

In order to solve the above problems, efforts have been made to formulate pickering emulsion type products with small amounts of monohydric alcohols.

However, robustness during the transport and filling process (robustness) still remains to be improved.

There is therefore a need for a composition of the pickering emulsion type which has an aesthetic appearance, for example a pearly appearance, and which is at the same time stable over time and temperature and moreover has improved robustness during the transport and filling process.

-hydrophobic silica.

A further subject of the present invention is a method for making up/caring for keratin materials such as the skin, in particular the face and the lips, by applying to said keratin materials a composition according to the invention.

The term "pickering emulsion" refers to an emulsion stabilized by solid particles (e.g., colloidal silica) adsorbed at the interface between the two phases.

The term "keratin material" means skin (skin around the body, face and eyes), hair, eyelashes, eyebrows, body hair, nails, lips or mucous membranes.

The term "visible oil droplets" according to the present invention refers to oil droplets having a volume median particle size Dv50 of between 0.01 mm and 10 mm. The oil droplets are visible by observing them with the naked eye.

The term "stability" means that the composition does not undergo any significant change in its structure or properties at least 1 month after its manufacture and even at least 2 months after its manufacture.

The term "robustness during the transport or filling process" means that the composition of the invention does not undergo any significant changes in its structure or properties during transport and during the filling process.

Detailed Description

The compositions of the present invention are intended to solve the problems listed above.

Fat phase

According to the invention, the composition comprises a dispersed fatty phase. The dispersed fat phase comprises at least one oil.

In particular, the fatty phase of the invention is in the form of droplets.

More particularly, the volume median diameter Dv50 of the droplets is from 0.01 mm to 10 mm, preferably from 0.05 mm to 5 mm.

Even more preferably, the volume median particle diameter Dv50 of the droplets is 0.1 mm.

The volume median Particle diameter Dv50 is a Particle size distribution parameter, meaning the maximum Particle diameter at which 50% of the sample volume is present (see a Basic Guide To Particle Characterization, page 10, malvern instruments Limited, published 2012).

The volume particle size Dv50 of the oil droplets can be determined by static light scattering using a commercial particle size analyzer, such as a MasterSizer3000 machine from Malvern. The data were processed based on Mie scattering theory. This theory, which is accurate for isotropic particles, makes it possible to determine the "effective" particle diameter in the case of non-spherical particles. This theory is described in particular in the publication by Van de Hulst, H.C. "Light carving by Small Particles", chapters 9 and 10, Wiley, New York, 1957.

Preferably, the composition may comprise a fatty phase, which is present in the composition in a content ranging from 0.1% to 40% by weight, preferably from 1% to 30% by weight and more preferably from 3% to 20% by weight, relative to the total weight of the composition.

Hydrophobic silica

The composition of the invention comprises hydrophobic silica in a continuous aqueous phase.

The term "hydrophobic silica" is understood in the context of the present invention to mean both pure hydrophobic silica and particles coated with hydrophobic silica.

According to a particular embodiment, the hydrophobic silica usable in the composition of the invention is amorphous and of pyrogenic origin. They are preferably provided in powdered form.

Amorphous hydrophobic silicas of pyrogenic origin are obtained from hydrophilic silicas. The latter being made of silicon tetrachloride (SiCl)₄) Pyrolysis in the presence of hydrogen and oxygen in a continuous flame at 1000 ℃. They are subsequently rendered hydrophobic by treatment with halosilanes, alkoxysilanes or silazanes. The hydrophobic silica differs from the initial hydrophilic silica, in particular by the lower density of the silanol groups and by a smaller adsorption of water vapor.

According to this embodiment, the hydrophobic silica is preferably chosen from those having a specific surface area of between 50 and 500 m²(ii) silica having a number average particle diameter of 3 to 50 nm. These are the hydrophobic silicas and mixtures thereof described more particularly in the table below.

According to this embodiment, the hydrophobic silica used in the composition of the invention may also consist of particles completely or partially covered with silica, in particular of inorganic particles completely or partially covered with hydrophobic silica, such as pigments and metal oxides covered with hydrophobic silica. These particles may also have optical properties in the product and on the skin; for example, they may have an oil control (mattifying) or a slight whitening effect.

As the hydrophobic silica, a hydrophobic fumed silica treated with dimethylsiloxane at the surface, such as that sold under the name Aerosil R972 (INCI name: dimethylsilylated silica) by Evonik Degussa, is preferably used.

According to another particular embodiment, the hydrophobic silicas which can be used in the compositions of the invention exhibit a size ranging from 500 to 1500 m²Specific surface area per unit weight (SW) of/g and a representation of 1 to 1500 [ mu ] m as volume mean diameter (D [0.5]]Also referred to as volume median particle diameter Dv 50).

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

They are usually synthesized by sol-gel methods in a liquid medium, followed by usually supercritical fluids (most commonly supercritical CO)₂) Extracted and dried. This type of drying makes it possible to avoid porosity and shrinkage of the material. The Sol-Gel method and various drying operations are described in detail in Brinker CJ. and Scherer G.W., Sol-Gel Science: New York: Academic Press, 1990.

The hydrophobic silica aerogel particles used in the present invention exhibit 500-1500 m²G, preferably 600-1200 m²G, more preferably 600- & lt800 & gt m-²The expression of the specific surface area per unit weight (SW) and 1-1500 [ mu ] m, better 1-1000 [ mu ] m, preferably 1-100 [ mu ] m, in particular 1-30 [ mu ] m, more preferably 5-25 [ mu ] m, better 5-20 [ mu ] m, and even better still 5-15 [ mu ] m, of/g as the volume mean diameter (D [ 0.5)]Also referred to as volume median particle diameter Dv 50).

According to one embodiment, the hydrophobic silica aerogel particles used in the present invention exhibit a size expressed as the volume mean diameter (D [0.5], also referred to as volume median particle size Dv50) of 1 to 30 μm, preferably 5 to 25 μm, still better 5 to 20 μm, and even still better 5 to 15 μm.

The specific surface area per unit weight can be determined by The nitrogen absorption method (known as The BET (Brunauer-Emmett-Teller) method) described in The Journal of The American Chemical Society, volume 60, page 309, month 2 1938 and in accordance with The International Standard ISO 5794/1 (appendix D). This BET specific surface area corresponds to the total specific surface area of the particles under consideration. The size of the silica aerogel particles can be determined by static light scattering using a MasterSizer 2000 commercial particle size analyzer from Malvern. The data were processed based on Mie scattering theory. This theory (accurate for isotropic particles) makes it possible to determine the "effective" particle diameter in the case of non-spherical particles. This theory is described in particular in the publication by Van de Hulst, h.c. "Light carving by smallpartides", chapters 9 and 10, Wiley, New York, 1957.

According to one advantageous embodiment, the aerogel particles of the hydrophobic silica used in the present invention exhibit 600-800 m²Specific surface area per unit weight (SW) and a representation of 5-20 [ mu ] m and even better 5-15 [ mu ] m in terms of volume mean diameter (D [ 0.5)]Also referred to as volume median particle diameter Dv 50).

The silica aerogel particles used in the present invention can advantageously exhibit a density of 0.04g/cm³-0.10g/cm³And preferably 0.05g/cm³-0.08g/cm³The tap density (p).

In the context of the present invention, such a density, called tap density, can be evaluated according to the following scheme:

pouring 40 g of powder into a graduated cylinder; the cylinder was then placed on a Stav 2003 apparatus from a Stampf Volumeter; the cylinder was then subjected to a series of 2500 taps (this was repeated until the difference in volume between 2 consecutive experiments was less than 2%); the final volume V of the tapped powder is then measured directly on a measuring cylinder_f. By the ratio w/V_f(in the present case, 40/V_f) Determination of tap Density (V)_fIn cm³And w is represented by g).

According to one embodiment, the aerogel particles of hydrophobic silica used in the present invention exhibit a particle size ranging from 5 to 60 m²/cm³Preferably 10 to 50 m²/cm³And more preferably 15-40 m²/cm³Specific surface area per unit volume SV.

By the relation: SV = SW x ρ gives the specific surface area per unit volume,where ρ is in g/cm³Tap density of and SW is in m as defined above²Specific surface area per unit weight expressed in/g.

Preferably, the aerogel particles of hydrophobic silica according to the invention have an oil absorption capacity (absorption capacity) measured at the wet point of between 5 and 18 ml/g, preferably between 6 and 15 ml/g, and better still between 8 and 12 ml/g.

Oil absorption measured at the wet point (marked W)_p) Corresponding to the amount of oil required to add to 100g of granules to obtain a homogeneous paste.

Measured according to the "wet-point" method or the method described in standard NF T30-022 for determining the oil absorption of the powder. Which corresponds to the amount of oil adsorbed onto the active surface of the powder and/or absorbed by the powder, measured by the following wet-point measurement:

an amount of w = 2g of the powder was placed on a glass plate and then oil (isononyl isononanoate) was added dropwise. After 4-5 drops of oil were added to the powder, mixing was performed using a spatula and the addition of oil was continued until aggregates of oil and powder were formed. From this point on, oil was added at a rate of one drop at a time, and the mixture was then milled with a spatula. The addition of oil was stopped when a compact and smooth paste was obtained. This paste must be able to spread on a glass plate without cracking or forming lumps. The volume Vs of oil used (expressed in ml) is then noted.

The oil absorption corresponds to the ratio Vs/w.

The aerogels used according to the invention are hydrophobic silica aerogels, preferably hydrophobic silica aerogels of silylated silica (INCI name: silylated silica).

The term "hydrophobic silica" is understood to mean any silica whose surface is treated with a silylating agent, for example with a halosilane, such as an alkylchlorosilane, a siloxane, in particular a dimethylsiloxane, such as hexamethyldisiloxane, or a silazane, in order to functionalize the OH groups with silyl Si-Rn, for example trimethylsilyl.
