Description

The present invention relates to a kit for applying makeup to a surface, such as skin, nails, hair, lips, or even artificial nails, and also relates to a method of applying makeup.

The term “cosmetic composition” as used in the context of the present invention refers to the EEC Directive 93/35 modified EEC Directive 76/768 dated 14 June 1993 (EEC Directive 93/35 modifying EEC Directive 76/768). ) Means the composition defined in). Foundations, lipsticks, and manicure liquids are examples of cosmetic compositions.

There is a need in the field of makeup to benefit from the effects of a new appearance, and the present invention seeks to satisfy that need.

Kit for applying makeup According to one aspect of the present invention, the present invention provides a kit for applying makeup to a surface, e.g., skin, nails, hair, or lips. And the kit
Particles of iron metal, in particular a first cosmetic composition comprising a soft iron (C _1); and the first composition for coating (C _1), or the first composition (C ₁₎ to be covered by the Second cosmetic composition (C ₂ )
including.

According to another aspect of the invention, the invention is a kit for applying makeup to a surface, such as skin, nails, hair, lips, or even artificial nails, comprising:
A first cosmetic composition comprising magnetic particles that are mobile under the influence of a magnetic field;
A second cosmetic composition for coating the first composition or for being coated with the first composition;
A magnetic device for creating a magnetic field that, when applied to the surface in the form of at least one layer, allows to move and / or change the orientation of all or part of the magnetic particles Is to provide a kit that also contains

The term “mobile” means that the orientation and / or position of the particles can be changed.

The appearance of the first composition deposited on the surface depends on the orientation and / or position of the magnetic particles. The present invention makes it possible to create a new makeup effect with a cosmetic composition, allowing a relief-like pattern to be created, for example giving a relief impression, or possibly various other geometric patterns .

The second composition may be transparent. When the second cosmetic composition is applied to the first composition, the second composition can obtain depth, gloss, smoothness, or other effects.

The second composition can include a colorant, such as a pigment. When the second composition is colored, it is possible to create a colored background / base, for example the second composition is coated, for example with the first composition.

In particular, the kit of the present invention can be used to apply makeup to the lips or nails.

The kit of the present invention may include a magnetic device for creating a magnetic field that allows the appearance of the first composition to be altered at least immediately after the first composition is applied to the surface.

First cosmetic composition After a given drying time, the first composition may be in a state that prevents the magnetic particles from further changing their orientation under the influence of a magnetic field. This is for example the case for Manucia liquor. Under certain circumstances, the orientation of the magnetic particles can also be altered at any time, especially when the first composition does not dry or exhibits a very long drying time. This may be the case for example in a foundation.

As described above, the first composition includes magnetic particles that can be presented in various forms.

Magnetic particle The term "magnetic particle" is also referred to as "magnetic material" and refers to particles that are sensitive to magnetism, i.e., particles that are sensitive to the action of a magnetic field and tend to be aligned with magnetic field lines, for example. means.

The first composition can include both magnetic and non-magnetic particles.

The presence of magnetic and non-magnetic particles in the composition makes it possible to create new optical effects that can be changed, for example under the influence of a magnetic field.

In the absence of a magnetic field, the magnetic particles used preferably do not show any residual magnetism.

The magnetic particles may include magnetic materials that are sensitive to the magnetic field lines, whether the magnetic field is created by a permanent magnet or the result of induction, the materials being nickel, cobalt, iron, and alloys thereof And oxides, in particular Fe ₃ O ₄ , and for example gadolinium, terbium, dysprosium, erbium, and their alloys and oxides. The magnetic material may be of a “soft” or “hard” type.

The magnetic particles may optionally exhibit a multilayer structure comprising at least one layer of a magnetic material, such as iron, nickel, cobalt and their alloys and oxides, in particular, for example Fe ₃ O ₄ .

The magnetic particles are preferably non-spherical and exhibit an elongated shape, for example. That is, when the particles are subjected to a magnetic field, they tend to be oriented with their long axis aligned with the magnetic field lines, and the orientation changes, resulting in a change in the appearance of the first composition.

When the magnetic particles are substantially spherical, their appearance is preferably non-uniform so that a change in orientation results in a change in appearance.

The amount of magnetic particles is sufficient to allow the appearance of the composition to depend on its orientation and / or its location.

The concentration of the magnetic particles is, for example, in the range of about 0.05% to about 97% by weight, such as preferably in the range of about 0.1% to about 95%, preferably in the range of 0.1% to 90%. It can be in the range, for example about 3% by weight. For example, the size of the magnetic particles can range from 1 nanometer (nm) to 700 micrometers (μm), such as from 1 μm to 500 μm, and more particularly from about 10 μm to about 150 μm. The term “size” means the size given by the statistical particle size distribution in half of the population, called “D50”.

The magnetic particles of the first composition can include a magnetic pigment. A particularly suitable pigment is a nacre containing iron oxide Fe ₃ O ₄ . For example, pigments exhibiting magnetism include Caralona Black Star Blue, Caralona Black Star Green, Caralona Black Star Gold, Caralona Black Star Red, Croisonenu Antique Super Green, Microna Matte Black (17437), Mica Flamenco Twilight Red, Flamenco Twilight Green, Flamenco Twilight Gold, Flamenco Twilight Gold, Flamenco Twilight Blue, Chimicanu under the trade names of Black (17260), Caralona Patina Silver (17289), and Caralona Patina Gold (117288) Antique Silver 110AB, Chimicanu Antique Gold 212GB, Chimicanu Antique Copper 340AB, Chimicanu Antique 240AB, Croisonenu Antique Green 828CB, Croisonenu Antique Blue 626CB, Gemtone Moonstone G004, Croisonenu Antique Red 424 Chroma-Light, Black (4498), Croisonenu Antique Rouge Flambe (Code 440XB), Croisonenu Antique Bronze ( 240XB), Croisonenu Antique Gold (222CB), and Croisonenu Antique Copper (340XB).

The magnetic particles may be magnetic fibers.

Magnetic fiber The term "fiber" generally refers to an elongated object that exhibits a form factor in the range of, for example, 3.5-2500 or 5-500, for example 5-150. Form factor is defined by the ratio L / D. Where L is the length of the fiber and D is the diameter of the circle where the widest cross section of the fiber is inscribed.

For example, the cross section of the fiber can be inscribed in a circle having a diameter in the range of 2 nm to 500 μm, such as in the range of 100 nm to 100 μm, or even 1 μm to 50 μm.

For example, the fibers may exhibit a length in the range of 1 μm to 10 millimeters (mm), such as 0.1 mm to 5 mm, or even 0.3 mm to 3.5 mm.

For example, the fibers may exhibit a weight ranging from 0.15 denier to 30 denier (weight in grams for a 9 km yarn), for example, ranging from 0.18 denier to 18 denier.

The cross section of the fiber can be any shape, for example a circle or a polygon, in particular a quadrangle, hexagon or octagon.

The composition may comprise solid or hollow fibers that may be independent or interconnected, eg knitted.

The composition may comprise fibers having ends that are not pointed and / or rounded, for example by polishing.

When the fiber is inserted into the composition, the shape of the fiber need not be significantly changed, where the fiber is initially straight and hard enough to keep its shape. In deformation, the fibers may exhibit a flexibility that allows them to be significantly deformed within the composition.

The fibers are non-zero (may be 100%) soft magnetic materials, hard magnetic materials, especially those based on iron, zinc, nickel, cobalt, or manganese, and their alloys and oxides, especially Fe. Magnetic materials selected from ₃ O ₄ , rare earths, barium sulfate, iron-silicon alloys (optionally containing molybdenum), Cu ₂ MnAl, MnBi or mixtures thereof (this list is not limiting) May be included.

When the composition comprises fibers comprising magnetic particles, the magnetic particles can be present on at least the surface of the fibers, or only on the surface of the fibers, or only within the fibers, or the fibers in a substantially uniform manner, for example. It may even be dispersed in it.

For example, each fiber can include a non-magnetic core having a plurality of magnetic particles on its surface.

Each fiber may also include a synthetic matrix that includes a plurality of magnetic grains dispersed therein.

If appropriate, the synthetic material itself filled with magnetic particles may be coated with a non-magnetic film. For example, such a film may constitute a barrier that isolates the magnetic material from the surrounding environment and / or it may impart color. Each fiber may include a one-piece magnetic core and may be coated with a non-magnetic film, or may include a continuous non-magnetic core and coated with a magnetic film.

The composition may include fibers made by extruding or co-extruding one or more polymeric materials, particularly thermoplastics and / or elastomers. One of the extruded materials may include dispersed magnetic particle filler.

Each fiber consists of polyamide; polyethylene terephthalate (PET); acetate; polyolefin, especially polyethylene (PE) or polypropylene (PP); polyvinyl chloride (PVC); polyester block amide; plasticized rilsan (TM); A synthetic material selected from polyester elastomers, polyethylene (PE) elastomers, silicone elastomers, nitrile elastomers; or mixtures of these materials, this list is not limiting.

The composition may comprise bicomponent fibers, each fiber comprising a magnetic core at least partially coated with at least one non-magnetic, synthetic, or natural material. For example, the magnetic core may be coated by coextruding a film made of a non-magnetic material around the core.

The core may also be coated in some other way, for example by in situ polymerization.

The core may be a single piece or may contain magnetic particle filler dispersed in a matrix.

The composition may also include bicomponent fibers obtained by coating a non-magnetic, synthetic or natural core with a synthetic material viewed with magnetic particles, where the core is wood; rayon; polyamide; plant Or consisting of fibers made from materials; or polyolefins, in particular polyethylene, nylon, polyimide-amide, or aramid, this list is not limiting.

The composition may also contain magnetic composite particles, in particular magnetic latex.

Magnetic composite particle The magnetic composite particle is a composite material composed of an organic or inorganic matrix and magnetic particles. Within its surface and / or itself, the magnetic composite particles can thus comprise grains of magnetic material. The composite particles can be composed of a magnetic core coated with an organic or inorganic matrix, or they can be composed of an organic or inorganic core coated with a magnetic matrix.

The magnetic composite particle includes, for example, one of the above-described magnetic substances.

The size of the magnetic composite particles may be in the range of 1 nm to 1 mm, for example, preferably in the range of 100 nm to 500 μm, more preferably in the range of 500 nm to 100 μm. The term “size” means the size given by the statistical particle size distribution in half of the population, called “D50”.

C. dated March 24, 2004. The theory by GOUBAULT (incorporated herein by reference) refers to the prior art on the problem of magnetic composite particles in Chapter 1 and is suitable for use in manufacturing magnetic composite particles, That is, a list is selected of synthesizing the magnetic grains and the matrix separately, synthesizing the magnetic grains in contact with the matrix, or synthesizing the matrix in the presence of the magnetic grains.

KISKER markets inorganic matrix magnetic composite particles made of silica. DYNAL, SERADYN, ESTAPOR, and ADEMTECH propose organic matrix magnetic composite particles suitable for use in the present invention.

More particularly, under the product number M1-070 / 60, ESTAPOR markets a magnetic latex composed of ferrite grains evenly distributed in a polystyrene matrix. The latex contains 65% iron oxide, the average diameter of polystyrene particles is 890 nm, and the dry matter mass content is 10%.

The ferrofluid composition may comprise a ferrofluid, i.e. a stable colloidal suspension of magnetic particles, in particular magnetic nanoparticles.

Particles having a size on the order of several tens of nanometers are dispersed, for example, in a solvent (water, oil, organic solvent), by a surfactant or dispersant, or by electrostatic interaction.

For example, a ferrofluid may be polished with ferrite or other magnetic particles until nanoparticles are obtained, which are then dispersed in a fluid containing a surfactant (which is adsorbed by and stabilizes the particles). Can be manufactured. Or they can be produced by precipitating a metal ion solution in a basic medium.

Each particle of the ferrofluid exhibits a magnetic moment that is determined by the size of the particle and the nature of the magnetic material.

Under the action of a magnetic field, the magnetic moment of the particles tends to be aligned with the lines of magnetic force, and non-zero magnetization appears in the liquid. If the field is removed, there is no hysteresis and the magnetization falls to zero.

Beyond the field threshold, it is possible to cause a macroscopic change in the liquid, for example the appearance of a peak or a change in rheological properties.

The term “ferrofluid” also includes an emulsion of drops of ferrofluid in a solvent. That is, each drop contains colloidal magnetic particles in a stable suspension. This makes it possible to obtain a ferrofluid in any type of solvent. The size of the magnetic particles in suspension in the ferrofluid may be in the range of 1 nm to 10 μm, such as preferably in the range of 1 nm to 1 μm, more preferably in the range of 1 nm to 100 nm. The term “size” means the size given by the statistical particle size distribution in half of the population, called “D50”.

Particular mention may be made of magnetic fluids sold by Liquid Research under the following reference names.
WHKS1S9 (A, B, or C), a water-based ferrofluid containing magnetite (Fe ₃ O ₄ ) with 10 nm diameter particles.
WHJS1 (A, B, or C), a magnetic fluid based on isoparaffin containing particles of magnetite (Fe ₃ O ₄ ) having a diameter of 10 nm.
BKS25 Dextran, a water-based ferrofluid stabilized by dextran, containing magnetite (Fe ₃ O ₄ ) particles having a diameter of 9 nm.

Particle and / or chain of magnetic fibers The composition has a maximum dimension, e.g. in the range of 1 nm to 10 mm, e.g. in the range of 10 nm to 5 mm, or in the range of 100 nm to 1 mm, or in the range of 0.5 [mu] m to 3.5 mm. Even may include, for example, a population of particles or fibers having a length that may range, for example, from 1 μm to 150 μm. The term “size” means the size given by the statistical particle size distribution in half of the population called “D50”.

For example, magnetic particle chains are described in the publication E.I. M. Furst, C.D. Suzuki, M. Fermigier, A. P. “Permanently bound monodisperse paramagnetic chains” by Gast, Langmuir, Vol. 14, pages 7334-7336 (1998), M.M. Fermigier, Y. “Suspension of Magnetic Particles” by Grasselli, Bulletin of the SFP (Vol. 105) 1996, July, and C.I. Goubault, P.A. Jop, M.M. Fermigier, J.A. Baudry, E.M. Bertrand, J.A. Bibette's "Flexible magnetic filament as a micromechanical sensor", Phys. Rev. Lett. 91, No. 26, 260802-1 to 260802-4 (2003), can be obtained by assembling colloidal magnetic particles. The contents of the above documents are incorporated herein by reference.

In particular, the above paper contains a polystyrene matrix containing iron oxide grains with functional groups on the surface, and is magnetically bonded together in a permanent manner according to chemical reaction, in particular with covalent bonds between the surfaces of adjacent particles. A procedure for obtaining a chain of latex particles is described; a method for obtaining a chain of ferrofluid-emulsion droplets that are bound together by physical interaction is also described. The length and diameter of the permanent chain obtained in this way can be controlled. Such magnetic chains constitute anisotropic magnetic objects that can be oriented and moved under the influence of a magnetic field.

The dimensions of the magnetic chains can satisfy the same conditions as for magnetic fibers.

For example, the first composition may include at least one goniochromatic colorant that can be observed to change color as a function of viewing angle. The goniochromatic coloring agent may optionally be magnetic.

When the first composition comprises a color of magnetic particles and a goniochromatic colorant, the colorant can be selected such that its color range substantially passes the color of the magnetic particles.

For example, this can make it more difficult to detect magnetic particles unless they are oriented under the influence of a magnetic field.

This can also allow the pattern induced by orienting the magnetic particles to appear sharp only when the makeup surface is under certain viewing and / or illumination conditions.

Goniochromatic colorant The term “goniochromatic colorant” as used in the context of the present specification refers to the observation of light at an angle of incidence of 45 ° when the composition is spread on the surface. The color in the a ^* b ^* plane of the 1976 CIE color space corresponding to a change Dh of the tint angle h of at least 20 ° when the angle is changed in the range 0 ° to 80 ° with respect to the normal. Means a colorant that makes it possible to obtain a bath.

For example, the color pass is manufactured by Instrument Systems after the first composition is spread in a fluid state to a thickness of 300 μm by an automatic spreader on a contrast card made of Eriksen and called type 24/5. Thus, it can be measured by a spectrologniorificometer called GON360 goniometer. Measurements are made on the black background of the card.

For example, the goniochromatic colorant can be selected from multilayer interference structures and liquid crystal colorants.

The multilayer structure may include, for example, at least two layers, and each layer includes, for example, the following materials: MgF ₂ , CeF ₃ , ZnS, ZnSe, Si, SiO ₂ , Ge, Te, Fe ₂ O ₃ , Pt, Va , Al ₂ O ₃ , MgO, Y ₂ O ₃ , S ₂ O ₃ , SiO, HfO ₂ , ZrO ₂ , CeO ₂ , Nb ₂ O ₅ , Ta ₂ O ₅ , TiO ₂ , Ag, Al, Au, Cu, Manufactured from at least one material selected from the group consisting of Rb, Ti, Ta, W, Zn, MoS ₂ , cryolite, alloys, polymers, and combinations thereof.

The multilayer structure may optionally be symmetrical about the central layer with respect to the chemistry of the stacked layers. Depending on the thickness and nature of the various layers, various effects can be obtained.

Examples of symmetric multilayer interference structures are as follows: Fe ₂ O ₃ / SiO ₂ / Fe ₂ O ₃ / SiO ₂ / Fe ₂ O ₃ (Pigments having these structures are sold by BASF under the trade name Chicopearl. MoS ₂ / SiO ₂ / Mica oxide / SiO ₂ / MoS ₂ ; Fe ₂ O ₃ / SiO ₂ / Mica oxide / SiO ₂ / Fe ₂ O ₃ ; TiO ₂ / SiO ₂ / TiO ₂ and TiO ₂ / Al ₂ O ₃ / TiO ₂ , (pigments having these structures are sold by Merck (Darmstadt) under the trade name Xylona).

For example, liquid crystal colorants include silicones or cellulose ethers onto which mesomorphic groups are grafted. Examples of suitable liquid crystal goniochromatic particles are those sold by Schenix and those sold under the trade name of Helicone ™ by Wacker.

Suitable goniochromatic coloring agents are nacres; pigments that have an effect on synthetic substrates, in particular alumina, silica, borosilicate, iron oxide, or aluminum type substrates; or holographic interference flakes coming from polyterephthalate films .

The material may further comprise dispersed goniochromatic fibers. Such fibers may exhibit a length that is, for example, less than 80 μm.

The first composition can also include at least one diffractive pigment that can exhibit magnetism, if desired.

Diffractive pigments The term "diffractive pigments" that can be used in the context of the present invention is a color that depends on the angle of observation due to the presence of structures that diffract light when illuminated by white light. It means a pigment that can cause a change.

The diffractive pigment may include a diffraction grating capable of diffracting monochromatic incident light in a defined direction.

The diffraction grating may include a periodic pattern, particularly a line, where the distance between two adjacent patterns is the same as the wavelength of the incident light.

When the incident light is multicolored, the diffraction grating separates the various spectral components of the light, creating a rainbow effect.

Regarding the structure of diffractive pigments, it is useful to refer to the paper by Alberto Argoitia and Matt Witzman, “Pigments Showing Diffraction Effects”, 2002, Society of Vacuum coaters, Bulletin 2002 of the 45th Technical Conference.

Diffractive pigments having various contours, in particular triangular contours which may be symmetrical, contours which may be equidistantly spaced, or sinusoidal contours may be produced.

The spatial frequency of the grid and the depth of the pattern are selected according to various desired orders of separation. The frequency can range, for example, from 500 lines per mm to 3000 lines per mm.

Each particle of the diffractive pigment preferably exhibits a flat shape, in particular a wafer shape.

A single pigment particle may comprise two crossed diffraction gratings, which may optionally be orthogonal.

The diffractive pigment can exhibit a multilayer structure comprising a layer of reflective material coated with a layer of dielectric material on at least one surface. The dielectric material may make the diffractive pigment harder and last longer. For example, selecting a dielectric material i.e. following _{materials, MgF 2, SiO 2, Al} 2 O 3, AlF 3, CeF 3, LaF 3, NdF 3, SmF 2, BaF 2, CaF 2, LiF, and combinations thereof Can be done. For example, the reflective material may be selected from metals, alloys thereof, and non-metallic reflective materials. Metals that can be used include Al, Ag, Cu, Au, Pt, Sn, Ti, Pd, Ni, Co, Rd, Nb, Cr, and their materials, combinations or alloys. Such a reflective material can itself constitute a diffractive pigment comprising a single layer.

In a variant, the diffractive pigment may comprise a multilayer structure comprising a core of dielectric material with a reflective layer covering at least one surface or indeed completely encapsulating the core. The layer of dielectric material may also cover the reflective layer. The dielectric material used is thus preferably inorganic, and can be selected, for example, from metal fluorides, metal oxides, metal sulfides, metal nitrides, metal carbides, and combinations thereof. The dielectric material may be in a crystalline, semi-crystalline, or amorphous state. In this configuration, dielectric materials include, for example, the following materials: MgF ₂ , SiO, SiO ₂ , Al ₂ O ₃ , TiO ₂ , WO, AlN, BN, B ₄ C, WC, TiC, TiN, N ₄ Si ₃ , It may be selected from ZnS, glass particles, diamond-type carbon, and combinations thereof.

In a variant, the diffractive pigment is a preformed dielectric material or ceramic material, such as a natural lamellar mineral, such as mica peroskovite or talc; or a synthetic platelet formed from glass, alumina, SiO ₂ , It can be composed of mica coated with carbon, iron oxide / mica, BN, BC, graphite, or bismuth oxychloride, and combinations thereof.

Instead of a layer of dielectric material, other materials that improve the mechanical properties are suitable. Such materials include silicones, metal silicides, semiconductor materials formed from group III, IV, and group V elements, metals having a body centered cubic crystal structure, metal-ceramic compositions or materials. , Semiconductor glasses, and various combinations thereof.

In particular, the diffractive pigment used may be selected from those described in US Patent Application Publication No. 2003/0031870, published February 13, 2003.

The diffractive pigment can have the following structure, for example. MgF ₂ / Al / MgF ₂ , a diffractive pigment having this structure, is sold by Flex Products under the trade name Spectrarea 1400 Pigment Silver or Spectrarea 1400 Pigment Silver FG. The proportion by weight of MgF ₂ can range from 80% to 95% by weight relative to the total weight of the pigment.

For example, the amount of diffractive pigment can range from 0.1% to 5% by weight relative to the total weight of the first composition.

For example, the size of the diffractive pigment can range from 5 μm to 200 μm, preferably from 5 μm to 100 μm, such as from 5 μm to 30 μm.

The thickness of the diffractive pigment particles can be 3 μm or less, or preferably 2 μm or less, for example about 1 μm or less.

Reflective particles For example, the first composition may comprise reflective particles, particularly flakes that may be magnetic in some cases.

The term “reflective particles” as used in the context of the present invention refers to them in terms of their size and structure, in particular the thickness of their constituent layers and their physical and chemical properties, and their surface state. It means a particle that makes it possible to reflect incident light. If appropriate, when the composition or mixture is applied to the surface to be made up, the reflection may have sufficient intensity to produce an emphasis point on the surface of the composition or mixture; The emphasis points appear to the naked eye, i.e. they are points of greater brightness compared to their environment and appear to shine.

The reflective particles may be selected in a manner that does not significantly change the color effect created by the colorant associated with them, and more particularly to optimize its effect on color yield. More particularly, the reflective particles may have a yellow, pink, red, bronze, orange, brown, and / or copper gloss.

The reflective particles are present in the range of 0.5% to 60% by weight, in particular 1% to 30% by weight, more particularly 3% to 10% by weight relative to the total weight of the first composition. It may be present in the composition.

The particles may be in various forms. In particular, the particles may be in the form of flakes or they may be globular, in particular spherical.

Regardless of its form, the reflective particles may optionally have a multilayer structure; together with the multilayer structure, for example, the particles may have at least one layer of a uniform thickness of the reflective material in particular. Good.

When the reflective particles do not have a multilayer structure, they may be composed, for example, of metal oxides, in particular titanium or iron oxides obtained by synthesis.

When the reflective particles have a multilayer structure, the particles are at least partly coated, for example, with a natural or synthetic substrate, in particular with a reflective material, in particular with at least one layer of at least one metal or metallic material. In particular, it may contain a synthetic substrate. The substrate can be a single substance or many substances, which can be organic and / or inorganic.

More particularly, it can be selected from glass, ceramic, graphite, metal oxides, alumina, silica, silicates, in particular aluminosilicates, and borosilicates, synthetic mica, and mixtures thereof. This list is not restrictive.

The reflective material may include a metal or a layer of metallic material.

Magnetic device The magnetic device may comprise a permanent magnet or an electromagnet operated, for example, by at least one battery optionally rechargeable. For batteries, the magnetic device may include a switch that allows the electromagnet to be selectively activated electrically.

Magnetic devices can be arranged to create a magnetic field with an orientation that varies over time. When the magnetic device includes a magnet, the device can include, for example, a motor that allows the magnet to be rotated. In a variation, the magnetic device may include a plurality of solenoids arranged to create a rotating magnetic field when activated sequentially with electricity.

For example, a rotating magnetic field may make it possible to obtain a pattern that exhibits circular symmetry, for example a pattern that gives the impression of a sphere in the relief.

The electromagnet can be operated continuously or intermittently as desired by the user. In particular, the magnetic device may be arranged so that the electromagnet does not need to be activated while the magnetic device is not properly positioned near the surface coated with the first composition.

The magnetic field is at least 50 millitesla (mT), for example, preferably at least 66 mT.

To facilitate applying a magnetic field, the magnetic device may include a member that allows the magnetic device to be positioned relative to the surface on which the first composition is deposited. This makes it possible to prevent the magnetic device from accidentally coming into contact with the composition and / or to make the pattern formed in the area under consideration centered.

In the practice of the present invention, the magnetic device is held in an applicator, such as an applicator used to apply the first cosmetic composition. This makes it possible to reduce the number of objects that need to be manipulated by the user and make it easier to apply makeup.

In another implementation of the invention, the magnetic device is attached to the first end of a rod having a second end connected to the handle of an applicator, such as an applicator used to apply a first cosmetic composition. Includes attached magnet.

The magnetic field can also be applied by magnetic structures, particularly flexible structures such as alternating N and S poles. For example, such a structure may allow a repeated pattern, such as a stripe, to be formed on the first composition.

Method of applying makeup According to another aspect of the present invention, the present invention also provides a method of applying makeup to a surface comprising the following steps.
Depositing at least a first composition and a second composition in a fluidized state on a surface, wherein the first composition covers or is coated with a second composition, the first composition being a magnetic field Including at least a portion of the first composition exposed to a magnetic field and orienting and / or moving at least a portion of the magnetic composition to The process of changing the appearance.

Exposure to a magnetic field can occur before and / or after the second composition is applied to the surface or the first composition.

A magnetic field may be applied to form at least one pattern on the first composition, the pattern being related to the shape of the magnetic field lines, for example.

As noted above, when the second cosmetic composition is applied to the first composition, the second composition allows depth, gloss, smoothness, or other effects to be obtained. The second composition may be transparent. Alternatively, the second composition may be coated with the first composition, for example to create a colored background / base.

For example, the second composition can be for application to the lips or nails.

A magnetic field may be applied so that the transparency and / or color of at least one region of the face or body to which the first composition has been applied has a stereoscopic effect.

For example, when the cosmetic composition is a foundation, orienting the particles under the influence of a magnetic field changes the transparency of the composition and makes the facial appearance three-dimensional in areas exposed to the magnetic field. In particular, it makes it possible to apply cameo-type makeup. For example, a magnetic field can be applied to allow the sides of the face to be darkened so that they appear thinner.

The magnetic field may be applied until the first composition has a fixed appearance, i.e., until the appearance of the composition stops changing even if the magnetic field continues to be present. In variations, the magnetic field may be applied for a time that is shorter than the time that allows all of the magnetic particles in the exposed region to be permanently moved and / or oriented.

Because the transparency and / or color of the first composition changes gradually under the influence of a magnetic field, the user can stop applying the magnetic particles to the field when the first composition exhibits the desired appearance. .

In the practice of the present invention, a magnetic field is applied through the magnetic sheet. Depending on the shape of the sheet, the magnetic field lines have various shapes, which makes it possible to increase the number of patterns that can be created, for example, with a single magnet.

The magnetic field may be applied sequentially to different regions of the surface coated with the first composition.

The magnetic field may be applied to areas of the surface that are distant from each other, for example, to create a distant pattern.

In order not to change the appearance of the first composition in the region after the first composition has been deposited, the region of the surface coated with the first composition need not be exposed to a magnetic field.

The first composition and the second composition may be applied in various ways, e.g. preferably non-magnetic, e.g. by a cosmetic applicator selected from brushes, tufted endpieces, foams. Can be given. Or it can be applied without the use of an applicator, and the first composition and the second composition can be spread, for example with fingers, or sprayed, for example.

In the practice of the present invention, at least one of the first composition and the second composition is applied to the surface through a perforated mask. This makes it possible to create a predetermined pattern corresponding to the shape of the hole, for example. At least one region of the surface coated in the first composition can then be exposed to a magnetic field.

The invention will be better understood upon reading the following detailed description of a non-limiting implementation of the invention and examining the accompanying drawings.

For example, the resulting pattern can give the impression of a relief sphere as shown in FIG.

Next, the user, the first composition is applied a second composition C ₂ is a transparent manicure When dry.

To application of the second composition C ₂ makes it possible to create the effect of, for example, additional depth.

In an embodiment of the nail polish liquid FIGS. 1-5, the first composition C ₁ may have the following formulation, the amounts are expressed in weight percentages In all the following examples.

Example A

^* Nacres containing at least 14% of _Fe 3 _{O 4,} referenced in color Rona Pati Na Gold (117,288), sold by Merck.

The appearance of such manukia can be changed by applying a magnetic field before the manukia has time to dry.

After drying the first composition, the second composition C ₂ having the following formulation may be applied, for example, the first composition.

In an embodiment variant of the invention, for example, to create a colored background / base, second composition C ₂ is applied before the first composition C _1.

First composition C _1, namely it is possible to further reduce the coating.

The following example is an example of a second composition for making a colored background / base, the first composition having, for example, the formulation of Example A above.

Example B

The first composition of Example A contains only one type of magnetic pigment.

The following examples show the possibility of having in the first composition a magnetic pigment and another colored substance, for example a pigment with an optical effect, in this case a goniochromatic pigment.

Example C

The magnetic pigment is gold and the color is present on the color bath of the goniochromatic pigment.

Without magnetic excitation, the mixture exhibits a goniochromatic effect with no visible pattern, and the color of the magnetic pigment makes it possible to avoid masking the goniochromatic effect. It is possible to see a surface with a base color that changes from gold to pink.

In contrast, after applying a magnetic field, magnetic particles that become aligned with the magnetic field lines create a pattern that becomes superimposed on the color change resulting from the goniochromatic pigment. A golden colored pattern obtained with oriented magnetic pigment particles can appear on the pink base for any orientation condition with respect to the observer and / or the surface being made up.

For example, a second composition having the same formulation as that of Example A can be applied to the first composition after the first composition has dried.

The first composition may also include a magnetic pigment and, for example, a reflective pigment.

Example D

^* Nacres containing at least 14% of _Fe 3 _{O 4,} referenced in color Rona Pati Na Gold (117,288), sold by Merck.
