Description

Aerosol-expanded coloured cosmetic composition

The present invention relates to an aerosol-expanded cosmetic composition for caring for and/or making up keratin materials, in particular the skin.

According to the present invention, the term "keratin materials" means, in the broad sense, the skin, the lips, the hair and/or the eyelashes. Preferably, it refers to the skin.

Conventionally, cosmetic compositions are usually in the form of solutions, gels, more or less fluid creams or loose or compact powders. Now, users of skincare products are increasingly in search of products that are pleasant to use and that have a novel texture.

Thus, it has already been proposed to introduce a gas, generally air, into cosmetic compositions to give them a light texture and the appearance of a mousse. This is referred to as expanding. The expanded emulsions obtained are appreciated for their lightness on application.

Cosmetic compositions of this type are generally in the form of temporary mousses produced just before use.

These are either aerosol products dispensed from a pressurized container, by means of a propellant and thus forming a mousse, or compositions dispensed from a container by means of a mechanical pump connected to a dispensing head.

As aerosol-expanded cosmetic compositions for caring for and/or making up the skin, the prior art especially discloses patent applications EP 1 795 176 and WO 2010/086 695, which describe low-density expanded compositions comprising an aqueous phase, fillers and foaming surfactants.

There is, nevertheless, a need for expanded coloured cosmetic compositions that are satisfactory firstly in terms of expansion quality and stability and secondly in terms of makeup result (in particular homogeneity of the deposit and coverage). Advantageously, the desired expanded cosmetic compositions do not contain any foaming surfactant and have improved texture and comfort properties on application.

The Applicant has demonstrated that the use of a non-emulsifying crosslinked silicone elastomer in a base composition in the form of an oil-in-water emulsion comprising at least one dyestuff makes it possible, after expansion in the presence of a propellant gas, to obtain an expanded composition (mousse) that has good texture and comfort properties on application, and that also has good makeup result properties (homogeneity of the deposit and coverage), and which can achieve this in particular even in the presence of a large content of dyestuffs (e.g. pigments), for which it is known that they can have an impact on the cosmeticity and/or the makeup result of a composition, in particular of an oil-in-water emulsion.

The invention thus relates to an aerosol-expanded cosmetic composition for caring for and/or making up keratin materials, comprising, in a physiologically acceptable medium, at least one aqueous phase, an oily phase, at least one dyestuff and at least one non- emulsifying crosslinked silicone elastomer.

According to one particular mode, the composition according to the invention comprises at least 5% by weight and especially at least 8% by weight of dyestuffs, and at least 5% by weight and especially at least 8% by weight of pigments relative to the total weight of the said composition. The invention also relates to a cosmetic storage and dispensing kit that can form an aerosol-expanded composition, comprising

a) a base composition, comprising, in a physiologically acceptable medium, at least one aqueous phase, an oily phase, a dyestuff and at least one non-emulsifying crosslinked silicone elastomer, and

b) an expanded composition dispenser for dispensing the said base composition in the form of an aerosol-expanded composition, this dispenser comprising at least:

- a reservoir containing the base composition and a propellant, and

- a dispensing head, for dispensing the expanded composition. The invention also relates to a process for caring for and/or making up keratin materials, in particular the skin, comprising the application to the said keratin materials, in particular the skin, of an expanded composition as defined according to the invention.

The expanded composition according to the invention is advantageous in several respects. It has a light, creamy and fondant mousse texture on application to the keratinic materials. It spreads out easily, in particular onto the skin, and allows to obtain a uniform covering make-up, in particular of the skin without visible marks.

Furthermore, after application to keratin materials, in particular the skin, the makeup or the deposit obtained has a powdery, velvety finish and is comfortable to wear, having no drying-out or tautness effect; the made-up or treated skin is pleasantly soft. BASE COMPOSITION AND EXPANDED COMPOSITION

For the purposes of the invention, the terms "the composition" and "the compositions" mean the expanded cosmetic composition and/or the base composition.

The base composition serving to obtain the expanded composition has an ingredient composition similar to that of the expanded composition except for its higher density insofar as it is free of air or of hydrocarbon-based or inert gas. The expanded compositions according to the invention are stably formed in the form of a mousse by means of a base composition and a propellant.

BASE COMPOSITION The base composition according to the invention comprises, in a physiologically acceptable medium, at least one aqueous phase, an oily phase, at least one dyestuff and at least one non-emulsifying crosslinked silicone elastomer.

In particular, the content of dyestuff(s) is at least 5% or even at least 8% by weight relative to the total weight of the said composition.

These esters may be linear, branched or cyclic, and saturated or unsaturated. In particular, they are branched and saturated. They may also be volatile or non-volatile.

In particular, the hydrocarbon-based esters may correspond to the formula RCOOR' in which RCOO represents a fatty acid residue containing from 2 to 28 carbon atoms, and R' represents a hydrocarbon-based chain containing from 1 to 28 carbon atoms. More particularly, the groups R and R' are such that the corresponding ester is non-volatile.

The composition according to the invention advantageously comprises from 1 % to 40% by weight and preferably from 2% to 30% by weight of oily phase relative to its total weight. These contents take into account the oils that may be associated with the crosslinked silicone elastomers, when these elastomers are in the form of crosslinked silicone elastomer gels.

In particular, the non-volatile silicone oil(s) may be present in a content ranging from 5% to 25% by weight and in particular from 10% to 20% by weight relative to the total weight of the composition.

Nevertheless, according to one preferred mode, the composition of the invention comprises less than 1 % by weight, in particular less than 0.5% by weight or even less than 0.1 % by weight of waxes relative to the total weight of the said composition.

Non-emulsifying silicone elastomers

The expanded coloured composition and the coloured cosmetic base of the invention comprise at least one non-emulsifying elastomeric organopolysiloxane (also known as a silicone elastomer). It is more particularly a crosslinked silicone elastomer.

According to one particular mode, the crosslinked silicone elastomer is obtained by crosslinking addition reaction (A) of diorganopolysiloxane containing at least two hydrogens each bonded to a silicon, and (B) of diorganopolysiloxane containing at least two ethylenically unsaturated groups bonded to silicon, especially in the presence (C) of a platinum catalyst.

According to one preferred mode, the non-emulsifying crosslinked silicone elastomer is conveyed in a second silicone oil (especially one that is different from the oil described above), in particular a linear silicone oil with a viscosity ranging from 1 to 10 cSt.

The term "organopolysiloxane elastomer" or "elastomeric organopolysiloxane" or "silicone elastomer" means a supple, deformable organopolysiloxane with viscoelastic properties and especially with the consistency of a sponge or a supple sphere. Its modulus of elasticity is such that this material withstands deformation and has limited stretchability and contractability. This material is capable of regaining its original shape after stretching. For the purposes of the present invention, the term "non-emulsifying" silicone elastomer means organopolysiloxane elastomers not containing a hydrophilic chain, such as polyoxyalkylene or polyglycerol units. The non-emulsifying crosslinked silicone elastomer is a crosslinked elastomeric organopolysiloxane that may be obtained:

by a crosslinking addition reaction of a diorganopolysiloxane containing at least one hydrogen bonded to silicon and of a diorganopolysiloxane containing ethylenically unsaturated groups bonded to silicon, especially in the presence of a platinum catalyst; or

by a dehydrogenation crosslinking condensation reaction between a hydroxyl- terminated diorganopolysiloxane and a diorganopolysiloxane containing at least one hydrogen bonded to silicon, especially in the presence of an organotin reagent; or

by a crosslinking condensation reaction of a diorganopolysiloxane containing hydroxyl end groups and of a hydrolysable organopolysilane; or

by thermal crosslinking of an organopolysiloxane, especially in the presence of an organoperoxide catalyst; or

- by crosslinking of an organopolysiloxane with high-energy radiation such as gamma rays, ultraviolet rays or an electron beam.

Preferably, the elastomeric crosslinked organopolysiloxane is obtained by a crosslinking addition reaction (A2) of a diorganopolysiloxane containing at least two hydrogens each bonded to a silicon, and (B2) of a diorganopolysiloxane containing at least two ethylenically unsaturated groups bonded to silicon, especially in the presence (C2) of a platinum catalyst, for instance as described in patent application EP-A-295 886.

In particular, the organopolysiloxane may be obtained by reaction of dimethylvinylsiloxy- terminated dimethylpolysiloxane and of trimethylsiloxy-terminated methylhydropolysiloxane, in the presence of a platinum catalyst.

Compound (A2) is the base reactant for the formation of an elastomeric organopolysiloxane and the crosslinking takes place via an addition reaction of compound (A2) with compound (B2) in the presence of the catalyst (C2).

Compound (A2) is advantageously a diorganopolysiloxane containing at least two lower (for example of C2-C4) alkenyl groups; the lower alkenyl group may be chosen from vinyl, allyl and propenyl groups. These lower alkenyl groups may be located in any position of the organopolysiloxane molecule, but are preferably located at the ends of the organopolysiloxane molecule.

Such conditioning and dispensing devices conventionally comprise a pressurized container (reservoir) containing the product conditioned in aerosol form. The container may comprise, for example, a valve equipped with a hollow valve-actuating stem enabling controlled dispensing of the product to be applied. To this end, the known devices comprise a diffuser that is equipped with a collar enabling it to be fixed onto the pressurized container, in particular onto the valve cup, and with a diffusion head. In order to allow product to be dispensed, the head comprises a dispensing channel inside which is housed the hollow outlet stem of the container, and at least one product outlet orifice connected to the dispensing channel.

Advantageously, the outlet orifices may be arranged so as to obtain a diffusion grille.

Preferably, the diffuser is made by moulding at least one plastic. Thus, the collar and the head are advantageously made as a piece derived from plastic material.

The container is equipped with a product dispensing valve provided with an actuating stem for dispensing product when it is actuated. The base composition is as previously described. According to one particular embodiment, the base composition is in the form of an oil-in-water emulsion.

The propellant is especially chosen from air, hydrocarbon-based gases and inert gases, and mixtures thereof. Mention may be made in particular of hydrocarbon-based gases, for instance propane, n-butane or isobutane, and mixtures thereof; fluoro gases, for instance chlorodifluoromethane, dichlorodifluoromethane, difluoroethane, chlorodifluoroethane, dichlorotetrafluoroethane, etc., and mixtures thereof; fluorohydrocarbon gases; dimethyl ether and mixtures of dimethyl ether with one or more hydrocarbon-based gases; nitrogen, air and carbon dioxide and mixtures thereof may also be used as inert propellant gases in the present invention.

Degree of expansion (DE)

The degree of expansion (DE) obtained with a base composition according to the invention expanded in the presence of a propellant advantageously ranges from 200% to 600%, in particular from 300% to 500% or even from 300% to 400% according to the following formula:

in which "d emulsion" corresponds to the density of the emulsion before expansion and "d mousse" corresponds to the density of the mousse after expansion; the density "d" of a compound itself being defined as the ratio of its mass per unit volume to the mass per unit volume of a reference compound (which is water for liquid compounds).

The measurement of this degree of expansion is performed according to the following protocol:

- a container of known volume is filled completely, with levelling-off at the surface, with the emulsion and the amount of emulsion that is necessary and sufficient to fill the container is weighed (= mass per unit volume of the emulsion);

an identical container is completely filled, with levelling-off, with the expanded emulsion, and the amount of mousse that is necessary and sufficient to fill the container is weighed (= mass per unit volume).

The weighed masses per unit volume of emulsion and of mousse make it possible to calculate the DE according to the formula indicated above. The expanded composition is obtained according to the invention from a base composition in an expanded-composition aerosol dispenser containing, besides the base composition, a propellant (gas).

According to one particular mode, the dispenser comprises a reservoir ("pressurized container") containing the base composition and the propellant gas in liquid form and a dispensing head ("diffuser") for dispensing the expanded composition.

A valve is crimped onto the reservoir; it may or may not be equipped with a dip tube. In the case of an aerosol dispenser to be used head upwards, a dip tube is generally present; in the case of an aerosol dispenser to be used head downwards, no dip tube is present. According to a preferred mode, an aerosol dispenser to be used head upwards will be used.

The examples below are given as non-limiting illustrations. Unless otherwise mentioned, the amounts indicated are weight percentages relative to the total weight of the composition. Examples 1 to 3: Effects of different fillers and selection of the non-emulsifying silicone elastomers

The coloured base composition in oil-in-water emulsion form (before expansion) is prepared according to the following protocol:

Phase A1 is weighed out in the main beaker and the temperature of the contents of the beaker is raised to 70°C.

In the main beaker, A2 is added with stirring using a Moritz blender at a sufficient speed to create a vortex. The mixture is left to swell at 70°C with stirring until the thickeners A2 have been fully dispersed and swollen.

A pigmentary paste is prepared from phase A3 and is ground by three successive treatments in a three-roll mill.

Phase A3 is added to the main beaker at 70°C with stirring using a Moritz blender at a sufficient speed to create a vortex. The whole is left to disperse for a minimum of 10 minutes.

Phase B is weighed out in the second beaker and the solid elements are melted by heating to 80°C. After total melting of the constituents, the temperature of the contents of the beaker is cooled to 70°C.

The emulsion is prepared at 70°C with stirring using a Moritz blender at a sufficient speed to create a vortex.

After 10 minutes of emulsification, the temperature of the emulsion formed is cooled to room temperature by means of cold-water baths, while stirring using the

Moritz blender.

Phase C is added to the emulsion formed, followed by phases D and E, with sufficient stirring. Stirring is effected for at least 10 minutes. The composition thus prepared is then left to stand for 24 hours, and then expanded with aerosol according to the following protocol:

An amount Q of the emulsion is weighed out in an aerosol can. The valve is crimped onto the can.

- An amount Q' of propellant gas (isopropane/propane/butane mixture) is injected via the valve such that Q = 0.95 ^* (Q + Q').

Base composition 95 95 Propellant (isopropane/propane/butane) 5

The leaktightness of the aerosol is checked by dipping it for 10 minutes in a bath at 50°C and checking that there is no emission of gas bubbles in the bath. The diffuser is fixed onto the valve.

By using this aerosol device, an expanded coloured composition was obtained, which was evaluated for its texture and makeup properties on application, according to the method described below. Protocol for evaluating the makeup of expanded compositions

The expanded compositions 1 to 3 thus prepared are applied at a rate of 0.15 g of product per half-face.

They are applied directly with the fingers, hazelnut-sized amounts being dispersed on the cheeks, the chin, the nose and the forehead and then spread until the formula has dried. The sensory criteria on application (duration of the application, softness of the product, ease of application, sensation experienced, etc.) and the makeup result criteria (level of coverage of the foundation colour, of skin imperfections, uniformity of the result, marking) are evaluated. The composition of Example 1 (comparative with PMMA and Nylon fillers) dries very quickly and does not allow a uniform makeup result to be obtained. It also has a tendency to undergo pilling.

The composition of Example 2 (invention with silicone elastomer in the form of powder coated with a silicone resin) dries less quickly than composition 1 ; the makeup result is more uniform than that obtained for composition 1.

The composition of Example 3 (invention with silicone elastomer in the form of a gel in a silicone oil) dries even less quickly and produces the best makeup result (homogeneity, coverage).

The use of the silicone elastomers in these coloured base compositions thus makes it possible, after expansion, to reduce the drying time of the composition in comparison with Example 1 , and also to improve the makeup yield after deposition on the skin, with an optimum result in the case of the silicone elastomer in gel form (Example 3). It is thus possible to obtain an expanded composition from an oil-in-water emulsion concentrated in pigments, and having coverage equivalent to that of a standard foundation. Examples 4 to 6: Expanded compositions according to the invention

Three other compositions expanded according to the invention were prepared, with pigment contents respectively of 15%, 12.5% and 10% by weight relative to the total weight of the said base composition.

Base compositions (oil-in-water emulsions)

Compositions 4 to 6 were prepared according to the following protocol: • Phase A1 is weighed out in the main beaker and brought to a temperature of 65°C with stirring using a Moritz blender so as to create a gentle stirring vortex.

• A pigmentary paste is prepared with phase A2. Phase A2 is added with stirring into phase A1 while maintaining at 65°C, and the whole is mixed until the pigments are uniformly dispersed in phase A1.

• Phase B is melted and the temperature is adjusted to 65°C. The emulsion is prepared with stirring using a Moritz blender, and the temperature of the emulsion is then rapidly reduced.

• Phase C and phase D are added. After cooling the formulation to 25°C, phase E is added and stirring is continued.

Hardness/viscosity of the base composition (unexpanded)

The hardness and/or viscosity values of the base compositions (before expansion) were measured on compositions 4 to 6 according to the protocols described previously:

- Composition 4: average hardness of 38 g measured with a texturometer;

Composition 5: average hardness of 25 g measured with a texturometer; viscosity of 45 DU measured using a Rheomat 180 rheometer with a No. 3 spindle (i.e. 17 poises, that is to say 1 .7 Pa.s);

Composition 6: average hardness of 15 g measured with a texturometer; viscosity of 35 DU measured using a Rheomat 180 rheometer with a No. 3 spindle (i.e.

12.8 poises, that is to say 1 .28 Pa.s).

The formulations are then left to stand for 24 hours before being conditioned as aerosol by mixing.

Compositions 4 to 6 according to the invention form expanded compositions that are very easy to apply and give a uniform, matt makeup result.

Degree of expansion

The degree of expansion for composition 5 (with 12.5% pigments) was measured according to the protocol described previously in a 60 ml container with:

Emulsion density (before expansion) = 1.12

Mousse density (after expansion) = 0.25

i.e. a degree of expansion corresponding to 350%. Sensory evaluation

Composition 4 was evaluated by a panel of 10 fluid-foundation users, on the basis of the following criteria: application, perception, makeup result, and remanence and comfort in the course of the day.

The users appreciated the novel mousse texture of the composition of Example 4, the ease of application (glidance, softness) and its makeup performance: the remanence, comfort and coverage of the makeup result.

Instrumental evaluation

Compositions 4 to 6 were also evaluated for their mattness, colour and homogeneity performance, by means of a Chromasphere with a definition of 410x410 pixels, according to the following protocol:

the measurements are taken in a standardized manner at 20°C, before and after application with the bare fingers of 100 mg of composition onto the half-face of a model, at the following times:

TO = measurement on naked skin freed of makeup, before application of the test composition

Timm = measurement after application and drying (15 minutes) of the test composition

- T3h = measurement 3 hours after application of the composition

(Timm - TO) measurement of the effect of the makeup

(T3h - Timm) measurement of the remanence of the makeup

• Measurement of the immediate colour and the colour remanence

A colorimetric measurement of the skin before and after making up was performed by measuring the red, yellow and luminance indices, a^*, b^* and L^*, respectively. For each woman, an image is acquired using a Chromasphere, at a definition of 410x410 pixels. The results are expressed in the following manner: The colour is quantified by the red, yellow and luminance indices analysed by the camera (a^*, b^* and L^*, respectively). The colour remanence is calculated by the variation of these variables after 3 hours of makeup (deltaE94).

Here is the formula established in 1976:

AE* = - L₂)² + (a_L - a₂)² + ( - b₂)^z where:

Li,ai,bi are the coordinates in the colorimetric space of the first colour to be compared and L₂,a₂,b2 are those of the second colour. • Measurement of the immediate mattness and the mattness remanence

The mattness of a region of skin, for example facial skin, is measured using a polarimetric camera, which is a black and white polarimetric imaging system, with which images are acquired in parallel (P) and crossed (C) polarized light. By analysing the image resulting from subtraction of the two images (P-C), the brightness is quantified, by measuring the average greyscale of the brightest 5% of pixels corresponding to the bright areas.

More specifically, the measurements are performed on a panel of individuals, who are kept in an air-conditioned waiting room (22°C ± 2°C) 15 minutes before the start of the test. They remove their makeup and an image of one of their cheeks is acquired using the polarimetric camera. This image allows measurement of the gloss at TO before applying makeup. Next, about 100 mg of the composition described above are weighed out in a watch glass, and are applied with the bare fingers onto the half-face on which the measurement at TO was taken.

A negative value means that the makeup reduces the gloss of the skin and that it thus has a matt effect.

• Measurement of the immediate uniformity and the remanence of the uniformity

A colorimetric measurement of the skin before and after makeup was taken by measuring the averages for the planes a^* (green-red), b^* (blue-yellow) and L^* (luminance).

Each image obtained using the camera is processed by coxellography. The standard deviation of each monochromatic plane is calculated. The product of the three standard deviations is equal to the coxellographic index. This parameter is used for the statistical calculations. The more uniform the skin, the smaller the standard deviation. The coxellographic index changes in the same direction since is the product of the standard deviations in the three planes a^*, b^* and L^*.

For the measurements performed, it is considered that:

+ mild effect or low remanence

++ moderate effect or moderate remanence

+++ strong effect or good remanence

++++ very strong effect or very good remanence

The following results were obtained:

Composition 4 Composition 5 Composition 6

Compositions (15% pigments) (12.5% pigments) (10% pigments) Immediate matting effect +++ +++ +++

Mattness remanence performance ++ ++ ++

Colour effect +++ +++ +++

Mattness remanence performance ++ ++ ++

Uniforming effect +++ +++ ++

Uniformity remanence performance ++ ++ ++

Good mattness, colour and uniformity performance were obtained for the expanded compositions 4 to 6 according to the invention, with equivalent or even better performance (as regards the colour and the immediate uniforming effect) when compared with the base compositions (unexpanded) that were also evaluated according to the same protocol.
