Description

DESCRIPTION

COSMETIC COMPOSITION COMPRISING, A NON VOLATILE DMETfflCONE OIL, A NON

VOLATILE PHENYLATED SILICONE OIL AND A NON VOLATILE HYDROCARBONATED OIL

TECHNICAL FIELD

The present invention relates to a cosmetic composition, more particularly to a cosmetic composition for making up and/or caring for the skin and/or the lips, comprising at least a non volatile dimethicone oil, a non volatile phenylated silicone oil, a non volatile hydrocarbonated apolar oil, in a particular content.

The present invention also relates to the processes using such composition for making up and/or caring for the skin and/or the lips, comprising the application to the skin and/or the lips of such cosmetic composition.

BACKGROUND ART In general, when women use a makeup product, especially of lips products such as lipstick or lipgloss type, they wish this product to have, after application, comfort and good remanence on the skin or the lips, in particular not to be transferred, and in particular no color or a low level of color to be transfered. Moreover, the product has to be easy to apply and the deposit has to be shiny. However, in the past, it has been difficult to achieve composition that are homogenous and stable, and that enable forming a shiny deposit having a good color transfer resistance level.

Therefore, it is sought to further improve the cosmetic properties of the said compositions, in particular the applications properties such as the glide and the easiness to apply (easiness of the erosion of the composition in case of a solid composition) and to obtain a uniform (homogenous) deposit on the lips and/or the skin, and in particular to have a deposit on the skin and / or the lips that has a good transfer resistance, and in particular a good color transfer resistance. The deposit should also be sufficiently shiny and/or sparingly tacky or not tacky. DISCLOSURE OF INVENTION

The inventors have found, unexpectedly, that it turns out to be possible to overcome this drawback provided that at least a non volatile apolar hydrocarbon-based oil, a non volatile dimethicone oil and a non volatile phenylated silicone oil are used in combination in a particular content, preferably in a solid composition.

The aim of the present invention is to overcome these drawbacks and to propose a cosmetic composition that is homogenous, stable (for example no separation into two phases, and/or exsudation, and/or sedimentation of the pigments, in particular after 24 hours or 72 hours at room temperature), and capable, in particular to form a deposit (in particular on the lips) that has a very good or a good color transfer resistance level. Moreover, the composition of the invention has to be capable of affording good cosmetic properties; in particular applications properties such as glide and easiness to apply, in particular on the lips, and forming a deposit having at least an acceptable level of shine (moderately good, good or very good level of shine).

Thus, according to one of its aspects, the invention relates to a cosmetic composition for making up and/or caring for the skin and/or the lips, comprising in a physiologically acceptable medium, at least one fatty phase comprising:

from 5% to 70% by weight of non volatile hydrocarbonated apolar oil(s), or mixture thereof, relative to the total weight of the composition, and

from 5% to 40% by total weight of non volatile non phenylated silicone oil(s) having at least a dimethicone part, or mixture thereof, relative to the total weight of the composition, and

at least 5% by weight of non volatile phenylated silicone oil chosen from silicone oil having at least a dimethicone part, and from silicone oils having no dimethicone part, or mixture thereof, relative to the total weight of the composition.

Such a composition is stable and homogenous, and are preferably makeup compositions, whose deposition on keratin materials, and in particular the lips and/or the skin, is easy to apply (good glide, homogenous deposit) and the deposit has good transfer resistance after application (in particular, no transfer or poor transfer of the color of the deposit, in particular on a cup or a glass while drinking for example). Beside, the deposit obtained with such composition, is sparingly tacky or non-tacky, and has a good level of shine (moderately good to very good).

The present invention also relates to a cosmetic process for making up and/or caring for the skin and/or the lips, comprising at least the application to the said skin and/or the said lips of composition comprising, in a physiologically acceptable medium, at least one fatty phase comprising:

at least 5% by weight of non volatile phenylated silicone oil chosen from silicone oil having at least a dimethicone part, and from silicone oils having no dimethicone part, or mixture thereof, relative to the total weight of the composition. Advantageously, the composition under consideration according to the invention is an oil-in-oil type composition. In the oil in oil type cosmetic composition of the invention, the non volatile silicone oil(s) and the non volatile hydrocarbon oil(s) are in a stable oil in oil state before application, without being separated from each other. After application, the non volatile silicone oil(s) comes up to the surface of the deposit, and this separated non volatile silicone oil(s) covers an adherent layer of the non volatile hydrocarbonated oil(s). Therefore, the resulting composition has good transfer resistance and offers a good level of shine. Rubbing the lips again each other during application further enhance this separation. Advantageously, the composition under consideration according to the invention is anhydrous. Advantageously, the composition according to the invention is solid at 20°C.

PHYSIOLOGICALLY ACCEPTABLE MEDIUM For the purposes of the present invention, the term "physiologically acceptable medium" is intended to denote a medium that is suitable for the application of a composition to the skin and/or the lips, for instance the oils or organic solvents commonly used in cosmetic compositions.

The physiologically acceptable medium (acceptable tolerance, toxicology and feel) is generally adapted to the nature of the support onto which the composition is to be applied, and also to the form in which the composition is to be conditioned. As emerges from the examples below, the combination under consideration according to the invention proves to be most particularly effective for affording a composition whose deposit on the skin or the lips that simultaneously has improved gloss and non transfer properties. Beside, the deposit also exibit remanence over time, in particular of remanence of the colour of the deposit (no embrittlement or fragmentation of the deposit, which remains homogeneous) and satisfactory comfort properties, both on application (especially glidance, breakdown, thickness and uniformity of the deposit formed, and reduction of the tack on drying) and during wearing, namely softness, absence of a tacky sensation or of a sensation of tautness or dryness.

What is more, in the case of lipsticks (solid or liquid such as gloss), this improvement of non transfer and non tackiness or sparingly tackiness is not obtained at the expense of the shine, which is another property generally sought for a makeup product of this type. Specifically, contrary to all expectation, no matt effect of the cosmetic product containing the combination under consideration according to the invention is noted. The invention also preferably relates to a composition for making up and/or caring for the skin and/or the lips, comprising, in a physiologically acceptable medium, from 5% to 40% of non volatile non phenylated silicone oil(s) having at least a dimethicone part, or mixture thereof, at least 5% by weight of non volatile phenylated silicone oil chosen from silicone oil having at least a dimeticone part and silicone oil having no dimethicone part, and from 5% to 70% non volatile hydrocarbonated apolar oil(s),or mixture thereof, and at least one colouring agent.

The compositions under consideration according to the invention and used in the processes according to the invention may be in solid or liquid form at 20°C. BEST MODE FOR CARRYING OUT THE INVENTION

According to one preferred embodiment, in particular in the case of a composition intended for caring for and/or making up the lips, the composition used according to the invention is anhydrous or contains less than 3% by weight of water and preferably less than 1% by weight of water, relative to the total weight of the composition.

The term "anhydrous" especially means that water is preferably not deliberately added to the composition, but may be present in trace amount in the various compounds used in the composition. The composition according to the invention and or that used according to the process according to the invention may be in the form of a composition for making up the skin and/or the lips, especially for facial or bodily skin; it may be a complexion product such as a foundation, a face powder or an eyeshadow; a lip product such as a lipstick or a lipcare product; a concealer product; a blusher; an eyeliner; a Up pencil or an eye pencil; a body makeup product; a gloss (lip gloss). According to a first advantageous embodiment of the invention, the composition is intended for making up the lips and it is more particularly a lipstick (lipstick wand) or a gloss (liquid lipstick). Advantageously, the lipstick compositions according to the invention are anhydrous.

According to a first preferred embodiment of the invention, the composition is solid at 20°C.

For the purposes of the invention, the term "solid" characterizes the state of the composition at a temperature of 20°C. In particular, a solid composition according to the invention has, at a temperature of 20°C and at atmospheric pressure (760 mmHg), a hardness of greater than 30 Nm^"1 and preferably greater than 35 Nm^"1.

Protocol for measuring the hardness:

The hardness of a composition especially of lipstick wand type is measured according to the following protocol:

The stick of lipstick is stored at 20°C for 24 hours before measuring the hardness.

The hardness may be measured at 20°C via the "cheese wire" method, which consists in transversely cutting a wand of product, which is preferably a circular cylinder, by means of a rigid tungsten wire 250 μηι in diameter, by moving the wire relative to the stick at a speed of 100 rnm/rninute.

The hardness of the samples of compositions of the invention, expressed inNm^"1, is measured using a DFGS2 tensile testing machine from the company Indelco-Chatillon. The measurement is repeated three times and then averaged. The average of the three values read using the tensile testing machine mentioned above, noted Y, is given in grams. This average is converted into newtons and then divided by L which represents the longest distance through which the wire passes. In the case of a cylindrical wand, L is equal to the diameter (in metres). The hardness is converted into Nm^"1 by the equation below:

(Y x 10^"3 x 9.8)/L

For a measurement at a different temperature, the stick is stored for 24 hours at this new temperature before the measurement.

According to this measuring method, a solid composition according to the invention has a hardness at 20°C of greater than or equal to 30 Nm^"1, preferably greater than 35 Nm^"1 and preferably greater than 40 Nm^"1. Preferably, the composition according to the invention especially has a hardness at 20°C of less than 500 Nm^"1, especially less than 400 Nm^"1 and preferably less than 300 Nm^"1.

In particular, a composition whose hardness is greater than 30 Nm^"1 is said to be "solid" at 20°C and at atmospheric pressure (760 mmHg).

Preferably, the composition according to the invention especially has a value of hardness at 20°C comprised between 40 Nm^"1 and 200 Nm^"1. Preferably the hardness is comprised between 50 Nm^"1 and 200 Nm^'1, preferably between 60 Nm^"1 and 200 Nm^"1.

According to a second embodiment, the composition according to the invention is liquid at 20°C.

Protocol for measuring the viscosity The viscosity measurement is generally performed at 25°C, using a Rheomat RM180 viscometer equipped with a No. 4 spindle, the measurement being performed after 10 minutes of rotation of the spindle in the composition (after which time stabilization of the viscosity and of the spin speed of the spindle are observed), at a shear rate of 200 rpm. Preferably, the composition has at 25°C a viscosity of between 1 and 25 Pa.s, preferably between 2 and 20 Pa.s and preferably between 4 and 17 Pa.s.

The term "wax" for the purposes of the present invention, means a lipophiHc compound that is solid at room temperature (25°C), with a solid/liquid reversible change of state, having a melting point of greater than or equal to 30°C, which may be up to 200°C and in particular up to 120°C. In particular, the waxes that are suitable for the invention may have a melting point of greater than or equal to 45°C and in particular greater than or equal to 55°C.

By bringing the wax to the liquid state (melting), it is possible to make it miscible with the oils that may be present and to form a microscopically uniform mixture, but on returning the temperature of the mixture to room temperature, recrystallization of the wax in the oils of the mixture is observed.

For the purposes of the invention, the melting point corresponds to the temperature of the most endothermic peak observed by thermal analysis (DSC) as described in standard ISO 11357-3; 1999. The melting point of the wax may be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name MDSC 2920 by the company TA Instruments.

The measuring protocol is as follows:

A sample of 5 mg of wax placed in a crucible is subjected to a first temperature rise ranging from -20°C to 100°C, at a heating rate of 10°C/minute, it is then cooled from 100°C to -20°C at a cooling rate of 10°C/minute and is finally subjected to a second temperature increase ranging from - 20°C to 100°C at a heating rate of 5°C/minute. During the second temperature increase, the variation of the difference in power absorbed by the empty crucible and by the crucible containing the sample of wax is measured as a function of the temperature. The melting point of the compound is the temperature value corresponding to the top of the peak of the curve representing the variation in the difference in absorbed power as a function of the temperature.

The wax may especially have a hardness ranging from 0.05 MPa to 15 MPa and preferably ranging from 6 MPa to 15 MPa. The hardness is determined by measuring the compression force, measured at 20°C, using a texturometer sold under the name ΤΑ-ΤΧ2Ϊ by the company Rheo, equipped with a stainless-steel cylinder 2 mm in diameter, moving at a measuring speed of 0.1 mm/s, and penetrating into the wax to a penetration depth of 0.3 mm.

δ_ρ characterizes the Debye interaction forces between permanent dipoles and also the Keesom interaction forces between induced dipoles and permanent dipoles;

¾ characterizes the specific interaction forces (such as hydrogen bonding, acid/base, donor/acceptor, etc.); and

The term "pasty", within the meaning of the present invention, is understood to mean a lipophilic fatty compound with a reversible solid/liquid change of state exhibiting, in the solid state, an anisotropic crystalline arrangement and comprising, at a temperature of 23 °C, a liquid fraction and a solid fraction. The term "pasty compound", within the meaning of the invention, is understood to mean a compound having a hardness at 20°C ranging from 0.001 to 0.5 MPa, preferably from 0.002 to 0.4 MPa.

The hardness is measured according to a method of penetration of a probe into a sample of compound and in particular using a texture analyser (for example, the ΤΑ-ΧΤ2Ϊ from R eo) equipped with a stainless steel cylinder with a diameter of 2 mm. The hardness measurement is carried out at 20°C at the centre of 5 samples. The cylinder is introduced into each sample at a pre-rate of 1 mm/s and then at a measuring rate of 0.1 mm/s, the depth of penetration being 0.3 mm. The value recorded for the hardness is that of the maximum peak. In addition, this pasty compound is, at a temperature of 23°C, in the form of a liquid fraction and of a solid fraction. In other words, the starting melting temperature of the pasty compound is less than 23 °C. The liquid fraction of the pasty compound, measured at 23°C, represents 9 to 97% by weight of the compound. This liquid fraction at 23 °C preferably represents between 15 and 85%, more preferably between 40 and 85%, by weight.

The liquid fraction by weight of the pasty compound at 23 °C is equal to the ratio of the enthalpy of fusion consumed at 23 °C to the enthalpy of fusion of the pasty compound.

The enthalpy of fusion of the pasty compound is the enthalpy consumed by the compound to change from the solid state to the liquid state. The pasty compound is "in the solid state" when the whole of its mass is in the crystalline solid form. The pasty compound is "in the liquid state" when the whole of its mass is in the liquid form.

The enthalpy of fusion of the pasty compound is equal to the area under the curve of the thermogram obtained using a differential scanning calorimeter (DSC), such as the calorimeter sold under the name MDSC 2920 by TA Instrument, with a rise in temperature of 5 or 10°C per minute, according to the ISO Standard 11357-3: 1999. The enthalpy of fusion of the pasty compound is the amount of energy necessary to change the compound from the solid state to the liquid state. It is expressed in J/g. The enthalpy of fusion consumed at 23 °C is the amount of energy absorbed by the sample to change from the solid state to the state which it exhibits at 23 °C, composed of a liquid fraction and of a solid fraction.

The liquid fraction of the pasty compound measured at 32°C preferably represents from 30 to 100% by weight of the compound, preferably from 80 to 100%, more preferably from 90 to 100%, by weight of the compound. When the liquid fraction of the pasty compound measured at 32°C is equal to 100%, the temperature of the end of the melting range of the pasty compound is less than or equal to 32°C. The liquid fraction of the pasty compound measured at 32°C is equal to the ratio of the enthalpy of fusion consumed at 32°C to the enthalpy of fusion of the pasty compound. The enthalpy of fusion consumed at 32°C is calculated in the same way as the enthalpy of fusion consumed at 23°C.

The specific surface area per unit of mass may be determined via the BET (Brunauer-Emmett-Teller) nitrogen absorption method described in the Journal of the American Chemical Society, vol. 60, page 309, February 1938 and corresponding to the international standard ISO 5794/1 (appendix D). The BET specific surface area corresponds to the total specific surface area of the particles under consideration.

The size of the hydrophobic silica aerogel particles may be measured by static light scattering using a commercial granulometer such as the MasterSizer 2000 machine from Malvern. The data are processed on the basis of the Mie scattering theory. This theory, which is exact for isotropic particles, makes it possible to determine, in the case of non-spherical particles, an "effective" particle diameter. This theory is especially described in the publication by Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

According to one advantageous embodiment, the hydrophobic silica aerogel particles used in the present invention have a specific surface area per unit of mass (SM) ranging from 600 to 800 m²/g and a size expressed as the mean volume diameter (D[0.5]) ranging from 5 to 20 μηι and better still from 5 to 15 μιτι.

The hydrophobic silica aerogel particles used in the present invention may advantageously have a tamped density p ranging from 0.04 g/cm³ to 0.10 g/cm³ and preferably from 0.05 g/cm³ to 0.08 g/cm³. In the context of the present invention, this density, known as the tamped density, may be assessed according to the following protocol:

40 g of powder are poured into a measuring cylinder; the measuring cylinder is then placed on a Stav 2003 machine from Stampf Volumeter; the measuring cylinder is then subjected to a series of 2500 packing motions (this operation is repeated until the difference in volume between two consecutive tests is less than 2%); the final volume Vf of packed powder is then measured directly on the measuring cylinder. The tamped density is determined by the ratio m/V f, in this instance 40/V f (Vf being expressed in cm and m in g).

According to one embodiment, the hydrophobic silica aerogel particles that may be used in the present invention have a specific surface area per unit of volume Sv ranging from 5 to 60 m²/cm³, preferably from 10 to 50 m²/cm³ and better still from 15 to 40 m²/cm³.

The specific surface area per unit of volume is given by the relationship:

Sv - SM-P; where p is the tamped density expressed in g/cm³ and SMIS the specific surface area per unit of mass expressed in m /g, as defined above. Preferably, the hydrophobic silica aerogel particles according to the invention have an oil-absorbing capacity, measured at the wet point, ranging from 5 to 18 ml/g, preferably from 6 to 15 ml/g and better still from 8 to 12 ml/g. The oil-absorbing capacity measured at the wet point, noted Wp, corresponds to the amount of water that needs to be added to 100 g of particle in order to obtain a homogeneous paste.

It is measured according to the wet point method or the method for determining the oil uptake of a powder described in standard NF T 30-022. It corresponds to the amount of oil adsorbed onto the available surface of the powder and/ or absorbed by the powder by measuring the wet point, described below:

An amount m = 2 g of powder is placed on a glass plate, and the oil (isononyl isononanoate) is then added dropwise. After addition of 4 to 5 drops of oil to the powder, rnixing is performed using a spatula, and addition of oil is continued until a conglomerate of oil and powder has formed. At this point, the oil is added one drop at a time and the mixture is then triturated with the spatula. The addition of oil is stopped when a firm, smooth paste is obtained. This paste must be able to be spread on the glass plate without cracking or forming lumps. The volume Vs (expressed in ml) of oil used is then noted.

The oil uptake corresponds to the ratio Vs/m.

The hydrophobic silica aerogel particles that may be used according to the present invention are preferably of silylated silica type (TNCI name: silica silylate).

The term "hydrophobic silica" means any silica whose surface is treated with silylating agents, for example halogenated silanes such as alkylchlorosilanes, siloxanes, in particular dimethylsiloxanes such as hexamethyldisiloxane, or silazanes, so as to functionalize the OH groups with silyl groups Si-Rn, for example trimethylsilyl groups.

As regards the preparation of hydrophobic silica aerogels particles that have been surface-modified by silylation, reference may be made to document US 7470725.

Use will be made in particular of hydrophobic silica aerogels particles surface-modified with trimethylsilyl groups.

The examples below are presented as non-limiting illustrations of the field of the invention. Examples 1 to 5 of cosmetic formulae of solid lip product type (lipstick)

Five solid lip makeup formulae having the following compositions were prepared (lipsticks) (the percentages indicated are weight percentages). Formulae 1 and 2 illustrate the invention, and formulae 3, 4, and are comparative compositions outside the invention.

Preparation process

The compositions of Examples 1 to 5 were obtained according to the following protocol:

In a first stage, the fillers, pigments and/or active agents of the fatty phase were ground in a three-roll mill in part of the oily phase (in PENTAERYTHRITYLTETRAISOSTEARATE).

In parallel, the waxes and the rest of the liposoluble ingredients are introduced into a heating pan and mixed in the heating pan at a temperature of about 100°C with Rayneri blending until a homogeneous mixture was obtained. The ground pigmentary material was then incorporated into the mixture, along with the nacres, if present, and stirring was continued until the mixture was homogeneous.

Finally, the compositions were poured into moulds preheated to 40°C, to produce sticks 11,5 mm in diameter. The whole was then left to cool in a freezer for about one hour, and then placed at room temperature for 24 hours.

Evaluation The hardness of compositions 1 to 5 at 20°C was evaluated according to the protocol described previously. The measured values of the hardness of the compositions are listed in the table before.

For the comparative composition 5, the texture obtained was not hard enough to obtain a stick and to measure the value of the hardness.

For the comparative composition 5, it was not possible to obtain a stick and to measure the value of the hardness, because while mixing at high temperature, a phase separation has occured.

Each of the compositions obtained was placed for 72 hours at 24°C and at 47°C in order to evaluate the stability of the composition. More particularly, it is observed if the compositions remain homogenous (no phase separation and/or no exudation for example) and if the stick remain unchanged.

Each of the compositions was then applied to the lips in order to evaluate the application properties and the characteristics of the deposit obtained; and more particularly the easiness to apply (quantity of composition applied and glidance on application), the shine of the deposit, and the color transfer resistance, particularly on a cup. The color transfer resistance is evaluated after applying the composition and rubbing the lower and the upper lips together for 5 seconds, and by applying the lips on a white pottery cup 5 minutes after applying the compositions on the lips. The shine is evaluated according to the following protocol:

The composition is applied on Bio Skin (Beaulax) by fixed number of strokes and measure the shine by gloss meter(GM-268, MINOLTA) on the condition of 60degree iUuminating angle and 60degree acceptance angle.

The deposit amount is measured by its weight loss after application on the Bio Skin.

The results obtained are the following:

resistance good: the color was possible transfer

resistance level

is lower than for

formula 1 and 2,

but better than

for comparative

formula 4

Composition 1 , 2, 3 and 4 are solid enough as not to fracture or crack when it is applied to the hps or on a blenderm. Furthermore, compositions 1, 2, 3, and 4 are stable over time, without exudation or collapse, in particular after 1 month at 24°C, and 47°C. Beside, none of the obtained sticks is collapsing while being placed at 47°C, for compositions 1 , 2, 3, and 4.

On contrary, comparative composition 5 outside the invention (containing no non volatile phenylated silicone oil) is not homogenous (phase separation while mixing at high temperature) and is not hard enough to obtain a stick. Composition 5 not cosmetically acceptable : is to pasty and unhomogeneous to enable forming a homogenous acceptable deposit. No evaluation of the properties of shine and color transfert resistance could be realised.

Composition 1 and 2, according to the invention, comprising a non volatile hydrocarbonated apolar oil, a non volatile non phenylated dimethicone oil and a non volatile phenylated silicone oil are easy to apply on the lips (good and homogenous erosion (fondant, creamy sensation) of the stick while applying, and good or acceptable glide). The deposit obtained on the lips is thick, comfortable, and homogeneous. Beside, compositions 1 and 2 according to the invention enable forming a deposit having good or very good color transfer resistance on a cup. At the same time, these deposits obtained with composition 1 and 2 enable exhibit a good level of shine or a moderately good level of shine, but still acceptable.

The comparative composition 3 containing a non volatile hydrocarbonated apolar oil, a non volatile phenylated silicone oil, but containing no non volatile non phenylated dimethicone oil (these oils have been replace by a phenylated silicone oil) is easy to apply and its deposits on the lips has a good level of shine. But the deposit on the lips obtained with composition 3 has only a moderately good level of color transfer resistance whereas the deposits obtained with composition 1 and 2 illustrating the invention have a good or a very good color transfer resistance level (the color transfer resistance level of the deposit obtained with formula 3 is lower than for formula 1 and 2, but better than for comparative formula 4). Therefore, this composition 3 does not meet the objective of the invention. Comparative composition 4 comprising a non volatile non phenylated dimethicone oil and a non volatile phenylated silicone oil but no non volatile hydrocarbonated apolar oil (the apolar oil of compositions 1 has been replaced weight by weight by glyceryl isostearate) has a bad color transfer resistance. . Therefore, thought it is easy to apply and has a good level of shine, this composition does not meet the obj ective of the invention.
