Two-composition kit for making up the eyebrows and their contour; two- step makeup process

The present patent application relates to the field of making up keratin materials, in particular the eyebrows and the skin around the eyebrows. The invention relates more particularly to a makeup kit comprising a first base-coat composition

(A) intended to be applied onto said keratin materials, comprising, in an oily phase, a silicone resin, a silicone polyamide, a volatile hydrocarbon-based oil, a polar volatile solvent and a pigment, and a second top-coat composition (B) intended to be applied onto the coat formed by the first composition (A) and comprising an aqueous dispersion of film-forming polymer particles. The invention also relates to a two-step process for making up said keratin materials, consisting in successively applying said composition (A) and said composition

(B).

Various types of eyebrow makeup products currently exist on the market.

They may be based on makeup solutions: pencils, powders, which are hot-cast, ointments, etc. These solutions are effective for drawing and coloring the eyebrow, but are not long-lasting and the makeup results change in the course of the day.

Products also exist based on the use of direct dyes, but these products, although durably coloring the keratin fiber, do not durably color the skin, and do not allow the eyebrow to be drawn.

Products also exist based on oxidation dyes, but these products require mixing at the time of use and may give rise to an ammonia odor. Furthermore, this solution is perceived as chemical by users (Refectocils® product range).

One solution also consists in applying a water-resistant makeup product based on the combination of a silicone resin of MQ type with a high molecular weight silicone resin, but the makeup result of this solution lasts for a maximum of two days and does not make it possible to preview the final result before it is fixed (Wunderbrow 2® product range from Wonder 2).

A final solution consists in applying products containing a self-tanning active agent such as dihydroxyacetone DHA; optionally combined with direct dyes, but this solution is limited in terms of colors offered and the colors are mainly orangey (Brow Tattoo® product range from Maybelline).

It is known that modification of the eyebrow and in particular its color may have a strong impact on the perception of the face. Users of eyebrow coloring products are rather in search of a surface makeup action with a semipermanent result rather than a long-lasting coloring of oxidation dyeing type as used in the field of hair dyeing. While the result is semipermanent, i.e. able to be removed after a few washes with a shower gel or a makeup remover, users wish to conserve the control of the final result and in particular to visualize said result in an anticipated manner.

There is a need to find a novel process for semi-permanently making up the eyebrows and also suitable novel compositions which make it possible to obtain long-lasting eyebrows makeup lasting for more than two days, which offers a wide range of colors and which makes it possible to preview the final result before it is fixed.

The Applicant has discovered in the course of its investigations that this objective can be achieved with a two-step makeup process consisting in successively applying:

1 ) to said keratin materials, at least one first coat with a first anhydrous colored "base-coat" composition (A), comprising in an oily phase:

- at least one silicone resin; and

- at least one silicone polyamide; and

- at least one volatile hydrocarbon-based oil; and

- at least one volatile polar solvent; and

- at least one pigment; and

2) then, onto the coat formed by composition (A), applying at least one second coat of a second "top-coat" composition (B) comprising, in an aqueous phase, at least some solid particles formed from one or more film-forming polymers in suspension in said aqueous phase.

The first step of applying the "base-coat" composition (A) makes it possible to color the eyebrows and their contour and allows the consumer to preview the final result before fixing.

The second step of applying the "top-coat" composition (B) makes it possible to fix the makeup obtained on the eyebrows and their contour and to obtain a semi permanent makeup with good staying power which has good resistance to rubbing, to sebum, to washing with a shower gel and a makeup remover for a period of more than 2 days, notably from 3 to 5 days.

This discovery forms the basis of the present invention.

A first subject of the present invention is a kit for making up keratin materials, in particular the eyebrows and the skin around the eyebrows, comprising:

1 ) a first anhydrous colored“base-coat” composition (A) comprising in an oily phase:

- at least one silicone resin; and

- at least one silicone polyamide; and

- at least one volatile hydrocarbon-based oil; and

- at least one volatile polar solvent; and

- at least one pigment; and

2) a second composition (B) comprising, in an aqueous phase, at least some solid particles formed from one or more film-forming polymers in suspension in said aqueous phase.

A second subject of the present invention is a cosmetic process for making up keratin materials, in particular the eyebrows and the skin around the eyebrows, comprising:

- at least one first step of applying a first composition (A) as defined previously to said keratin materials, and - at least one second step, successive to said first step, of applying to the coat formed by composition (A) at least one second composition (B) as defined previously. Definitions

In the context of the present invention, the term "keratin materials" means the eyebrows and the skin around the eyebrows. For the purposes of the invention, the term "anhydrous composition" denotes, respectively, a composition which contains less than 5% by weight of water, preferably less than 2% by weight of water, indeed even less than 0.5% of water, relative to its total weight, and notably a composition which is free of water. OILY PHASE

The composition (A) of the invention comprises at least one oily phase comprising at least one hydrocarbon-based volatile oil. The term "oil" means a water-immiscible non-aqueous compound that is liquid at room temperature (25°C) and at atmospheric pressure (760 mmHg).

The term "liquid oil" means an oil that is capable of flowing under its own weight, at room temperature (20°C) and at atmospheric pressure (760 mmHg), as opposed to "solid" fatty substances.

The term“hydrocarbon-based oil” means an oil predominantly including carbon and hydrogen atoms and not comprising any silicon atoms. The term“volatile oil” means any oil with a vapor pressure of greater than or equal to 0.13 Pa measured at 25°C.

The oily phase preferably represents from 30% to 70% by weight, preferentially from 30% to 60% by weight and advantageously from 40% to 60% by weight relative to the total weight of composition (A).

Hvdrocarbon-based volatile oil

The hydrocarbon-based oil of the dispersion is preferably chosen from hydrocarbon-based oils containing from 8 to 16 carbon atoms and better still from 12 to 16 carbon atoms.

Advantageously, the hydrocarbon-based oil of the dispersion is apolar (thus formed solely from carbon and hydrogen atoms).

The volatile hydrocarbon-based oil may be chosen from:

- branched C8-C16 alkanes, for instance C8-C16 isoalkanes of petroleum origin (also known as isoparaffins), for instance isododecane (also known as 2, 2, 4,4,6- pentamethylheptane), isodecane, isohexadecane and, for example, the oils sold under the trade name Isopar or Permethyl,

Preferentially, the volatile hydrocarbon-based oil is isododecane. More particularly, the content of hydrocarbon-based volatile oil(s) ranges from 30% to 70% by weight, preferably from 30% to 60% by weight and more preferentially from 40% to 60% by weight, relative to the total weight of composition (A). PIGMENTS

As stated previously, the "base-coat" composition (A) according to the invention comprises at least one pigment. The term“pigment” means a pulverulent material, also known as a particulate material, formed from white or colored, mineral or organic particles, which are insoluble in an aqueous medium, and which are intended to color and/or opacify the resulting composition and/or film. These pigments may be white or colored, and mineral and/or organic.

These pigments are more particularly detailed below.

A composition (A) according to the invention preferably contains from 1 % to 25% by weight and preferentially from 4% to 20% by weight of these pigments, relative to the total weight of composition (A).

According to a particular embodiment, the pigments used according to the invention are chosen from mineral pigments. The term "mineral pigment" means any pigment that satisfies the definition in Ullmann’s encyclopedia in the chapter on inorganic pigments.

In the context of the present invention, the mineral pigments are more particularly metal oxides, for instance iron oxide and titanium dioxide. As mineral pigments that may be used in the invention, mention may be made in particular of nacres.

The term“nacres” should be understood as meaning colored particles of any form, which may or may not be iridescent, notably produced by certain molluscs in their shell, or alternatively synthesized, and which have a color effect via optical interference.

The nacres may be chosen from nacreous pigments such as titanium mica coated with an iron oxide, titanium mica coated with bismuth oxychloride, titanium mica coated with chromium oxide, titanium mica coated with an organic dye and also nacreous pigments based on bismuth oxychloride. They may also be mica particles, at the surface of which are superposed at least two successive layers of metal oxides and/or of organic dyestuffs.

Examples of nacres that may also be mentioned include natural mica covered with titanium oxide, with iron oxide, with natural pigment or with bismuth oxychloride.

Preferably, composition (A) of the invention comprises at least one pigment as defined above, coated with at least one hydrophobic surface agent as defined below.

HYDROPHOBIC SURFACE AGENT

For the purposes of the invention, a surface agent is a molecule that is capable of interacting with the surface of the pigment via a weak interaction, such as adsorption, or via a strong interaction, such as a chemical reaction.

The term "hydrophobic surface agent" means any lipophilic or hydrophobic compound which has interacted or which is interacting with the surface of the pigment(s).

The term "lipophilic compound" means any compound that is soluble or dispersible in an oily phase.

The term "hydrophobic compound" means any compound that is insoluble in water.

Without wishing to be bound to a particular theory, the presence of a hydrophobic surface agent in the composition makes it possible to disperse and stabilize better the pigment(s) in the oily phase of the composition.

A pigment coated with a hydrophobic surface agent is particularly advantageous insofar as it shows a predominant affinity for the oily phase of the composition which can then convey it.

For the purposes of the invention, a "coated pigment" according to the invention generally denotes a pigment that is totally or partially surface-treated with a surface agent, absorbed, adsorbed or grafted onto said pigment.

The surface-treated pigments may be prepared according to surface treatment techniques of chemical, electronic, mechanochemical or mechanical nature that are well known to a person skilled in the art. Commercial products may also be used.

The surface agent may be absorbed, adsorbed or grafted onto the pigments by evaporation of solvent, chemical reaction and creation of a covalent bond.

According to one variant, the surface treatment consists of coating the pigments.

The coating may represent from 0.1 % to 20% by weight and in particular from 0.5% to 5% by weight, relative to the total weight of the coated pigment.

A composition (A) according to the invention preferably contains from 1 % to 25% by weight and preferentially from 4% to 20% by weight of the combination of pigments and of coating agent, relative to the total weight of composition (A).

The coating may be produced, for example, by adsorption of a liquid surface agent onto the surface of the solid particles by simple mixing with stirring of the particles and of said surface agent, optionally with heating, prior to the incorporation of the particles into the other ingredients of the makeup or care composition.

The coating may be produced, for example, by chemical reaction of a surface agent with the surface of the solid pigment particles and creation of a covalent bond between the surface agent and the particles. This method is notably described in patent US 4 578 266.

The chemical surface treatment may consist in diluting the surface agent in a volatile solvent, dispersing the pigments in this mixture and then slowly evaporating off the volatile solvent, so that the surface agent is deposited at the surface of the pigments. According to a particular embodiment of the invention, the surface agent of the composition of the invention is chosen from silicone surface agents; fluoro surface agents; fluorosilicone surface agents; metal soaps; N-acylamino acids or salts thereof; lecithin and derivatives thereof; isopropyl triisostearyl titanate; isostearyl sebacate; natural plant or animal waxes; polar synthetic waxes; fatty esters; phospholipids; and mixtures thereof.

According to a more particular embodiment of the invention, the surface agent of the composition of the invention is chosen from silicone surface agents, in particular alkylsilanes and alkoxysilanes, notably triethoxycaprylylsilane; N- acylamino acids or salts thereof, in particular stearoyl glutamate; isopropyl triisostearyl titanate; and mixtures thereof.

Silicone surface agent According to a particular embodiment, the hydrophobic surface agent is a silicone compound.

The silicone surface agents may be chosen from organopolysiloxanes and silane derivatives, and mixtures thereof.

The term“organopolysiloxane compound” means a compound having a structure comprising an alternance of silicium atoms and oxygen atoms and comprising organic radicals bonded to silicon atoms. i) Non-elastomeric organopolysiloxane

Non-elastomeric organopolysiloxanes that may notably be mentioned include polydimethylsiloxanes, polymethylhydrogenosiloxanes and polyalkoxydimethylsiloxanes.

One method for surface-treating pigments with a polymethylhydrogenosiloxane consists in dispersing the pigments in an organic solvent and then in adding the silicone compound. On heating the mixture, covalent bonds are created between the silicone compound and the surface of the pigment.

According to a preferred embodiment, the silicone surface agent may be a non- elastomeric organopolysiloxane, notably chosen from polydimethylsiloxanes. ii) Alkylsilanes and alkoxysilanes Silanes bearing alkoxy functionality are notably described by Witucki in“A silane primer, Chemistry and applications of alkoxy silanes, Journal of Coatings Technology, 65, 822, pages 57-60, 1993”.

Alkoxysilanes such as the alkyltriethoxysilanes and the alkyltrimethoxysilanes sold under the references Silquest A-137® (OSI Specialities) and Prosil 9202® (PCR) may be used for coating the pigments.

Mention may also be made of the triethoxycaprylylsilane sold under the reference Unipure AS-EM® (Sensient).

The use of alkylpolysiloxanes bearing a reactive end group such as alkoxy, hydroxyl, halogen, amino or imino is described in patent application JP H07- 196946. They are also suitable for treating the pigments.

SILICONE RESIN

Composition (A) according to the invention comprises at least one silicone resin.

More generally, the term“resin” means a compound whose structure is three- dimensional. "Silicone resins" are also known as "siloxane resins". Thus, for the purposes of the present invention, a polydimethylsiloxane is not a silicone resin.

The nomenclature of silicone resins (also known as siloxane resins) is known under the name“MDTQ”, the resin being described as a function of the various siloxane monomer units it comprises, each of the letters“MDTQ” characterizing a type of unit.

The letter "M" represents the Monofunctional unit of formula R1 R2R3S1O1/2, the silicon atom being connected to only one oxygen atom in the polymer comprising this unit.

In this case, the structuring agent may be a polymer comprising at least one unit of formula (III) or (IV):

in which X, Y, n and R ⁴ to R ⁷ have the meanings given above, mi and m2, which are different, are chosen in the range from 1 to 1000, and p is an integer ranging from 2 to 300.

In this formula, the units may be structured to form either a block copolymer, or a random copolymer or an alternating copolymer. In this copolymer, the units may be not only of different lengths, but also of different chemical structures, for example containing different groups Y. In this case, the polymer may correspond to formula VI: in which R ⁴ to R ⁷ , X, Y, mi, m2, n and p have the meanings given above and Y ¹ is different than Y but chosen from the groups defined for Y. As previously, the various units may be structured to form either a block copolymer, or a random copolymer or an alternating copolymer. In this first embodiment of the invention, the structuring agent may also be formed from a grafted copolymer. Thus, the polyamide containing silicone units may be grafted and optionally crosslinked with silicone chains containing amide groups. Such polymers may be synthesized with trifunctional amines. In this case, the polymer may comprise at least one unit of formula (VII):

These polyamides containing a grafted silicone unit of formula (VII) may be copolymerized with polyamide-silicones of formula (II) to form block copolymers, alternating copolymers or random copolymers. The weight percentage of grafted silicone units (VII) in the copolymer may range from 0.5% to 30% by weight.

According to the invention, as has been seen previously, the siloxane units may be in the main chain or backbone of the polymer, but they may also be present in grafted or pendent chains. In the main chain, the siloxane units may be in the form of segments as described above. In the pendent or grafted chains, the siloxane units may appear individually or in segments.

According to one embodiment variant of the invention, a copolymer of silicone polyamide and of hydrocarbon-based polyamide, or a copolymer including units of formula (III) or (IV) and hydrocarbon-based polyamide units, may be used. In this case, the polyamide-silicone units may be located at the ends of the hydrocarbon-based polyamide.

Eyebrow makeup process

One subject of the present patent application is a cosmetic process for making up keratin materials, in particular the eyebrows and the skin notably around the eyebrows, which consists in applying to said keratin materials:

- at least one first step of applying a first composition (A) as defined previously to said keratin materials, and

- at least one second step, successive to said first step, of applying to the coat formed by composition (A) at least one second composition (B) as defined previously.

Between the application of the first coat with the base-coat composition (A) and the application of the second coat with the top coat composition (B), the drying time preferably ranges from 3 to 20 minutes, more preferentially from 5 to 15 minutes.

Packaging and applicators Compositions (A) and (B) according to the invention may each be packaged in a container delimiting at least one compartment that comprises said composition (A) or (B), said container being closed by a closing member.

The container may be in any suitable form. It may notably be in the form of a bottle, a tube, a jar or a case.

The closing member may be in the form of a removable stopper, a lid or a cover, notably of the type including a body fixed to the container and a cap articulated on the body. It may also be in the form of a member for selectively closing the container, notably a pump, a valve or a flap valve.

The container may be combined with an applicator, notably in the form of a brush including an arrangement of bristles maintained by a twisted wire. Such a twisted brush is described notably in patent US 4 887 622. It may also be in the form of a comb including a plurality of application members, obtained notably by molding. Such combs are described, for example, in patent FR 2 796 529. The applicator may be in the form of a fine brush, as described, for example, in patent FR 2 722 380. The applicator may be in the form of a block of foam or of elastomer. The applicator may be free (sponge) or securely fastened to a rod borne by the closing member, as described, for example, in patent US 5 492 426. The applicator may be securely fastened to the container, as described, for example, in patent FR 2 761 959.

The product may be contained directly in the container, or indirectly.

The closing member may be coupled to the container by screwing. Alternatively, the coupling between the closing member and the container occurs other than by screwing, in particular via a bayonet mechanism, by click-fastening or by tightening. The term“click-fastening” in particular means any system involving the crossing of a bead or cord of material by elastic deformation of a portion, notably of the closing member, followed by return to the elastically unconstrained position of said portion after the crossing of the bead or cord.

The container may be at least partially made of thermoplastic material. Examples of thermoplastic materials that may be mentioned include polypropylene and polyethylene.

The container may have rigid or deformable walls, notably in the form of a tube or a tube bottle.

The container may comprise means intended to bring about or facilitate the dispensing of the composition. By way of example, the container may have deformable walls so as to cause the composition to exit in response to excess pressurization inside the container, which excess pressurization is brought about by the elastic (or nonelastic) crushing of the walls of the container.

The container may be equipped with a wiping element positioned in the vicinity of the opening of the container. Such a wiping element makes it possible to wipe the applicator and possibly the shaft to which it may be solidly attached. Such a wiping element is described, for example, in patent FR 2 792 618.

Throughout the description, including the claims, the term "including a" should be understood as being synonymous with "including at least one", unless otherwise specified.

The expressions "between ... and ...", and "ranging from ... to ..." should be understood as meaning limits included, unless otherwise specified.

The invention is illustrated in greater detail by the examples and figures presented below. Unless otherwise indicated, the amounts shown are expressed as weight percentages.

EXAMPLE OF A MAKEUP KIT Composition (A) base coat

Preparation protocol

The starting materials were first weighed out carefully using a balance (precision = 0.01 g).

Phase 1 was prepared by wetting the pigments and the mica with the isododecane. This phase 1 was then milled with a three-roll mill.

Mixing of phases 1 and 2

The ingredients of phase 2 and of the milled phase 1 were melted in a jacketed heating pan in which circulates an oil whose temperature was controlled by means of a thermostatically-controlled oil bath. The nominal temperature was set at 90°C. After total melting, the mixture was homogenized with a Moritz blender. Stirring was continued until a homogeneous preparation was obtained (20 minutes). The mixture was then cooled with stirring.

Addition of phase 3

Phase 3 was introduced into phase 1 +2 when the temperature of the mixture was less than or equal to 40°C.

End of formulation

Composition (A) thus obtained was transferred into a closed container to prevent it from drying out on contact with air.

Composition (B) top coat I Water 70

The ingredients were introduced into a beaker and stirred for 10 minutes until homogeneous. A composition (B) which was stable for 2 months at room temperature (25°C) was obtained. in vitro staving power test

The process involving the application of the base coat (A) followed by the application of the top coat (B) led to significantly improved staying power during in vitro staying power tests, when compared with the prior art constituted by the application of a commercial semipermanent eyebrow makeup product, Wunder Brow 2®.

The compositions were applied with a dip applicator, of brush type, on yak bristles (50 mg) adhesively bonded by means of a Pros'Aide® adhesive bond to a silicone support of the BioSkin® type.

A first coat of 0.07 g of composition (A) was applied using a brush and then, after 10 minutes of drying, a second coat of 0.07 g of composition (B) was applied. The whole was left to dry for 4 hours. A first coat of 0.07 g of the product Wunder Brow 2® was applied using a brush and then, after 10 minutes of drying, a second coat of 0.07 g of the product Wunder Brow 2® was applied. The whole was left to dry for 4 hours.

A succession of tests was then performed on this dry deposit:

Succession of tests:

- mechanical abrasion (5 brush strokes + 5 strokes with cotton wool)

- sebum (olive oil - 5 drops - leaving on for 2 minutes - wiping with cotton wool) - shower gel (0.2 g of lauryl ether sulfate - 1.5 ml of water - 8 finger strokes, rinsing with warm water between 37 and 42°C for 10 seconds)

- care cream (Aquasource cream 0.2 g - leaving on for 2 minutes - wiping with cotton wool) - makeup remover (1.5 ml of micellar water, rubbed 5 times)

Notes A, B and C below were evaluated:

A: No change in the deposit relative to its level of application

5 B: White hairs appear (fewer than 10 hairs appear)

C: More than 10 hairs are freed of makeup and the color on the BioSkin® begins to fade out
