Description

The present invention relates to articles for the cosmetic treatment of human keratin materials by an electric current. For the purposes of the present invention, the term "article" means a mask, a patch, a pad, a strip or a strip that can be applied to human keratin materials. "Cosmetic product" means any composition as defined in Council Directive 93/35 / EEC of 14 June 1993. Passive masks for the application of cosmetic compositions are known. US6702792, for example, discloses a cellulose mask impregnated with a facial lotion. However, the quantity of molecules administered by the passive route remains reduced. To improve this aspect, patches or active masks have been developed using electrodes connected to a power source. It is thus known to treat human keratin materials using iontophoresis devices (J. Singh, KS Bhatia, topical iontophoretic drug delivery: pathways, principles, factors and skin irritation, Med Res Res, vol 16 , No. 3, 285-296, 1996).

Iontophoresis allows the diffusion of actives through the skin through electrical stimulation in a non-invasive way. The current administered can be adjustable in intensity and direction (anodal or cathodal). Transcutaneous diffusion of molecules via iontophoresis is based on two principles: electrorepulsion and electroosmosis. Electrorepulsion is the migration of an ionized molecule by repulsion of charges of the same sign. Thus, if a substance is positively charged, it will diffuse through the skin at the (+) anode. Electroosmosis is the migration of a molecule, even if not ionized, by driving linked to the flow of water from the anode to the cathode during iontophoresis. The migration is due in particular to the negative charge of the skin. Under the effect of a current, the water or a solvent causes, during their migration, dissolved substances. US 6157858, US 7069088, US 6157858 or US 7069088 disclose articles having at least one pair of electrodes. The electrodes are arranged on a malleable support. They are powered by a generator external to the support located within a housing. Before placing the article on a selected body area, a cosmetic composition is applied to this area. The article is then placed on the face and the electrodes are powered by electric current. The duration of treatment varies between 15 minutes and 1 hour. Such an article allows to apply a cosmetic on the selected body area. Thus, the entire area is treated with the same composition. Such equality of treatment can be problematic in the case where the zone comprises regions of different natures. For example, if the chosen area is the face, some regions may be fatter than others. Other areas of the face may also be more fragile than others. Still others may be more marked by fine lines or wrinkles. In addition, the composition is applied by the user to the target zone before treatment, which can lead to an inhomogeneous distribution of the active ingredient. CN 200951261 describes an article whose active electrode covers the entire face while the return electrode is attached to another part of the body. Electrical contacts and electrical wires connect the electrodes to the power source. The latter is contained in an outer casing. The mask is composed of an absorbent layer in contact with the skin, surmounted by a conductive layer of rubber. The cosmetic composition is contained in the absorbent tissue.

The article described in US Patent 5443441 has a basic structure similar to that described in CN 200951261, with the difference that the cosmetic composition is not contained in an absorbent tissue but in a reservoir separated from the skin by a semi-membrane. -permeable. Thus, the cosmetic composition is ready for use in the article.

The user saves time since he does not need to apply the composition on the face. However, this article is not easy handling due to the integration of the power source within an external box. In addition, the active electrode can produce an inhomogeneous contact between the article and the body area and, consequently, an inhomogeneous distribution of the current on the skin.

However, an inhomogeneous distribution of current can affect the user's comfort, for example by creating tingling or a burning sensation locally, where the current density is the strongest. Finally, these articles deliver the same cosmetic composition over the entire body area chosen. This whole area is treated in a uniform way, without taking into account any specificities. There is therefore a need for an electrical article for selectively and simultaneously treating different regions of a selected body area. This article must also be easy to manipulate.

There is still a need to provide an article allowing the application of at least two distinct cosmetic compositions to two contiguous regions of a body area of a user. There is also a need to reduce the clutter of existing articles. There is also a need to provide an article allowing the homogeneous application of a cosmetic composition containing an active ingredient, on each region of the selected area. The invention aims to solve all or part of the aforementioned needs as well as to further improve the cosmetic treatment articles of human keratin materials by an electric current.

The subject of the invention is, according to a first aspect, an article for the cosmetic treatment of a body area with an electric current comprising: (i) a support comprising: a first compartment comprising a first cosmetic composition and a first electrode a second compartment comprising a second cosmetic composition and a second electrode, and (ii) at least one counter-electrode. In particular, the article according to the invention is a mask for the face. The article according to the invention may in particular be used with a separate housing of the article, this housing comprising a power supply source. In this case, a new article is connected to the case during each treatment. The item is usually disposable after use. The article works in association with the case.

The article may also include its integrated power source. It then works autonomously. At the end of treatment, the user throws the article with its power source. If the article is a mask, it may have openings for the eyes, nose and / or mouth. The article may be occlusive or non-occlusive, for example being non-permeable to water vapor. By "face", it is necessary to understand the external zone of the front part of the head of a human being. The face includes the chin, mouth, lips, philtrum, nose, cheeks, cheekbones, eyes, eyebrows and forehead. Advantageously, each compartment covers an area chosen from the chin, the lips, the nose, the cheeks, the cheekbones, the eyebrows, and the forehead, when the article is in place on the face. According to the invention, the term "electrode" means an electrode positively charged (anode) or negatively (cathode). This electrode is generally disposed on the outer surface of the article to come into direct contact with the keratin materials. But, the electrode can also be inserted into the outer wall of the article. In this case, it does not come into direct contact with the keratin materials. In general, the electrode is in contact with the area to be treated.

Throughout the text, the term "electrode" means a single isolated electrode. An electrode may be for example in the form of a ball or block for example. The term "counter electrode" means a negatively charged electrode (cathode) or positively (anode) electrode. The charge of the counter-electrode is opposite to that of the electrode. Advantageously, the article comprises a first counter electrode and a second counter electrode. In particular, the first counter electrode is placed facing the first electrode and the second counter electrode is placed facing the second electrode. Thus, the user has no counter-electrode to hold in his hand. The article is easier to use. The article may alternatively comprise a single counter-electrode, especially if all the electrodes have the same polarity. The counter electrode is intended to come into contact with a body area of the person undergoing the treatment. For example, it can be grasped between the fingers of the person. In one configuration, the counter-electrode may be disposed at the edge of the article, in withdrawal of the compartments. In this event, it is separated from the electrodes by an insulating space. The term "electrical supply system" means an electrical assembly capable of inducing a potential difference between the electrodes and the counter-electrode. If the article is placed on the face and if the counter-electrode is held in one hand, the potential difference makes it possible to establish a current between the face and the hand. "Compartment" means a division practiced in an article for housing cosmetic compositions by separating them. Advantageously, the first compartment and the second compartment are separated by a separation zone. The separation zone is generally devoid of cosmetic composition. Thus, the two compartments are easily identifiable by the user. It is easy to place them in front of a chosen area. ELECTICAL ENERGY SOURCE The article may include a source of electrical energy therein. The integration of the electrical energy source of the mask can make it possible to dispense with electrical wires connecting the mask to an external source. The comfort of use of the mask is then increased and it becomes easier for the user to use the mask while moving or in his bath.

Advantageously, the article comprises a source of electrical energy, located on the support. The source of electrical energy can be fixed removably or not on the article. The source of electrical energy may, for example, be integrated into the mask during its manufacture. The energy source can be sandwiched between two outer layers of the article. It is still possible that the source of electrical energy is put in place in the article just before the treatment. It can then be proposed to the user separately from the mask.

The power source may include a DC voltage source. Alternatively, the source of electrical energy may comprise an electronic circuit for varying the amplitude of the voltage generated over time. This electronic circuit may, for example, be a chopper. The source of electrical energy may, for example, be connected to the electrodes without a circuit breaker. In this case, the electrical resistance between the electrodes may be sufficiently high that the source of electrical energy will not discharge when the article is not in operation. It is also possible to operate the source of electrical energy by pressing a portion of the mask to bring into contact said source of electrical energy with a conductive track.

ELECTRICAL PARAMETERS The power source may include any battery or accumulator. The potential difference between the electrodes is for example between 1.2 V and 24 V, preferably between 1.2 and 3.3 V. Where appropriate, the passage of the current can create a punctual heating. At equivalent current density, the article may in particular deliver a current density, at the level of the skin, preferably less than or equal to 0.500 mA / cm 2, for example between 0.01 mA / cm 2 and 0.500 mA / cm 2, for example between 0.01 mA / cm 2 and 0.10 mA / cm 2.

ELECTRODES The electrodes may have an apparent free surface allowing them to directly contact the skin. The electrode may be flat, for example in the form of a flat disk or a polygon. The electrode may be porous. The electrodes may have various shapes and for example a surface intended to come into contact with the skin which is outwardly convex, outwardly concave, or planar. Preferably, the electrodes are smooth, so as not to hurt the skin. The electrodes may be constituted by two spheres or rollers, which may or may not rotate in respective housings.

The electrode may be hollow, being for example formed by stamping or bending an electrically conductive sheet. Materials that can be used for producing the electrodes The material (s) constituting the electrodes may be identical or different. At least one electrode may, for example, comprise: a metal (chromium, stainless steel), for example a noble metal (gold, titanium), inert with respect to the composition, a metal plated with a noble metal, a alloy, - a composite material (plastic filled with carbon microfibres), - a conductive fabric, - a conductive nonwoven, - a polymer material made conductive, - a fibrous material, - conductive polymer fibers, for example as described in the publication CN101532190, carbon fibers, for example as described in the publication JP2009179915, silicones made conductive by the addition of conductive fillers such as silver, copper or carbon. Such silicones are, for example, provided by the companies Saint Gobain, Plastics Performance and Aquitaine Rubber 2000, conductive metal fabrics, for example supplied by the companies Utexbel and Cousin Biotech, carbonized vinyl, for example provided by the companies Copema and Rexam, - electrosurgical plates, for example provided by the companies Copema and 3M, - intrinsic conductive polymers, for example provided by Paniplast companies.

The article may comprise an electrically insulating layer, solidarisant the first and second electrodes. This layer can be an outer layer, the opposite of the skin.

The term "active surface of an electrode", the surface of an electrode in contact with the body area, when the article is in place on said body area. The term "active surface of a compartment", the surface of the compartment in contact with the body area, when the article is in place on said body area. Advantageously, the active surface of the first electrode is greater than one third of the active surface of the first compartment. The effectiveness of the treatment is optimized at the level of the first compartment. The treatment is more uniform on the body area next to the first compartment. Advantageously, the active surface of the second electrode is greater than one-third of the active surface of the second compartment. The effectiveness of the treatment is optimized at the level of the second compartment. The treatment is more uniform on the body area next to the second compartment. COSMETIC COMPOSITION The first cosmetic composition and the second cosmetic composition generally comprise at least one active ingredient. The active ingredient is preferably loaded. "Charged" means any active ingredient present at least partially in ionic form whose ions have a net charge either positive or negative, able to ensure their mobility within the composition under the effect of an electric field. Thus, the asset is directly subject to the attraction or repulsion of the electrodes. Advantageously, the first and second cosmetic compositions are chosen from care, washing, purification, exfoliation, desquamation, massage, thinning, makeup, make-up removing, cleaning or bleaching compositions. More preferably, the first composition and the second composition are in the form of an aqueous solution, an oil, an emulsion, a powder or a gel.

The first composition and the second composition may comprise different respective active principles, of opposite charges. Both compositions are preferably in the form of gels. Whatever the embodiments considered, the article may exert an action on the skin by iontophoresis and / or electroosmosis. The article promotes the migration of a composition to two regions of a contiguous body area. The two compositions may be the same or different. The composition may comprise an activating composition of an inactivated active ingredient present within the article, for example in lyophilized form. In this case, the composition may be devoid of a charged active ingredient. The composition may comprise a solvent having positively and negatively charged species, for example an ionic aqueous solution or deionized water or a solution of NaCl.

It is also possible for the user to apply an activating composition, for example a solvent, to the article. For example, it can apply running water, while it is not proposed in the same package with the article. To bring the article into contact with the activation composition, the user may pour the composition onto the article. The latter is, for example, present in a pouch or tray to pour the composition. Alternatively, the user can apply the composition to the skin and then apply the article on it. Advantageously, the first cosmetic composition and the second cosmetic composition are different from each other. In this case, two body areas of different natures can be treated with the same article.

ELECTROCHEMICAL REACTION In general, when seeking to administer an active ingredient using the mask according to the invention, said active ingredient has the same polarity as the electrode. For example, compounds containing active ingredients of polarity / positive charge such as Vitamin A, tocopheryl acetate or other active principles of charge / positive polarity may be associated with a positive polarity electrode.

Compounds containing active principles of polarity / negative charge such as retinyl palmitate, tocopherol, mandelic acid may, in turn, be associated with a negative polarity electrode. It is possible to treat a body area with an article whose compartments all allow the administration of active ingredients of the same polarity. It is also possible that certain compartments allow the administration of an active principle of one polarity and the other compartments, the administration of an active principle of opposite polarity. In all cases, the polarity of the electrodes and the counter-electrodes is determined by the polarity of the active principles of each compartment. THE SUPPORT Dimensions and structure The support can, in the unfolded state, present a larger dimension of between 15 and 80 cm, for example between 25 and 60 cm. The support may, in the unfolded state, have a thickness of between 0.1 cm and 1 cm and preferably between 0.2 cm and 0.5 cm. The medium can be configured to produce a sound and / or light signal, for example to warn the user that the exposure time on the skin is reached. After use, the article can be thrown in its entirety. Insulating layer The support may comprise an insulating layer, which may make it possible to secure the first and the second electrode. The insulating layer may be flexible.

The insulating layer may comprise any electrically insulating material, for example chosen from insulating thermoplastic materials such as polyamides, styrenics, polyolefins or vinyls. The electrode materials can be fixed to the insulating layer by gluing, welding or hot rolling.

Conductive tracks can be formed on the insulating layer by printing, etching, transfer or screen printing. Material of the support Advantageously, the support comprises a nonwoven material. The support is thus more flexible. It adapts better to the contours of the selected area. Nonwoven By "nonwoven" is meant for the purposes of the present invention a substrate comprising fibers wherein the individual fibers or filaments are arranged in a disordered manner in a sheet-like structure. The fibers of the nonwoven are generally bonded together, either under the effect of a mechanical action, or under the effect of a thermal action, or by the addition of a binder.

Such a nonwoven is for example defined by the ISO 9092 standard as a web or a layer of directionally or randomly oriented fibers, linked by friction and / or cohesion and / or adhesion, excluding paper and products obtained by weaving, knitting or stitching incorporating binding yarns or filaments. Advantageously, the mass percentage of heat fusible fibers contained in the nonwoven is greater than 0.5% and is less than or equal to 100%, advantageously between 5% and 80%. The heat-fusible fibers are, for example, polyolefin fibers, such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET) fibers or acrylic fibers, such as polymethyl methacrylate (PMMA) fibers, polyurethanes or fibers of the following thermoplastics: polyvinyl chloride (PVC), styrenic polymers (for example polystyrene PS, expandable polystyrene EPS, acrylonitrile butadiene styrene ABS terpolymer, styrene acrylonitrile copolymer SAN, styrene butadiene copolymer SB), polyamides (PA), polycarbonates (PC), saturated polyesters (for example polyethylene terephthalate glycol PET, polybutylene terephthalate glycol PBT), polyacetals (for example polyoxymethylene POM trioxane copolymer ethylene oxide), polyvinyl alcohol (PVA), or fluorinated polymers (for example polytetrafluoroethylene PTFE) polyvinylidene fluoride PVDF, polychlorotrifluoroethylene PCTFE) Others fibers constituting the nonwoven are for example synthetic fibers derived from petroleum derivatives, natural fibers from plants or animals, and / or modified natural fibers, for example from treatment or regeneration processes to form fibers .

The nonwoven may be formed from one or more consolidated fiber webs. Conductivity of a Nonwoven The conductivity of a nonwoven network depends on the type, amount, orientation and distribution of the incorporated conductive fibers. A nonwoven may have a resistance of less than 1500 ohms / square, or even less than 100 ohms / square, for example less than 10 ohms / square. The conductivity of a sample is calculated as the quotient of the sample resistance, expressed in Ohms, divided by the ratio of the length and width of the sample. The resistance obtained from the sample is expressed in Ohms-per-square. More specifically, the measurement of the resistance can follow the "Method for determining the Resistivity of a Printed Conductive Material" ASTM F1896-98 as described in the patent application WO 2009/144684.

The invention also relates to a cosmetic process comprising the steps of - setting up on a body area, particularly on the face, an article as defined above, - circulating an electric current within said article and put in place.

DESCRIPTION OF THE FIGURES The invention will be better understood on reading the following description of nonlimiting examples of implementation thereof and on examining the appended drawing, in which: FIG. 1 is a schematic front view of an exemplary embodiment of an article according to the invention, - Figure 2 shows schematically an alternative embodiment of the article.

In the figures, the actual relative proportions of the various elements have not, for the sake of clarity, not always been respected.

FIG. 1 shows a mask according to the invention configured to cover the face. This mask comprises a nonwoven support 13 with four compartments: - a compartment 1 to cover the front, - a compartment 2 to cover the nose, - two compartments 3 and 4 to cover the eye contour. Each compartment has an electrode: electrode 11 extends over almost the entire length of compartment 1, electrode 21 extends over almost the entire height of compartment 2, electrodes 31 and 41 extend over almost the entire length of the compartments 3 and 4. In the illustrated example, the mask is configured to treat almost the entire face, that is to say at the same time the eye contour, the nose and the front F The mask may, for example, be in the form of a hood. The mask may comprise, where appropriate, fixing means on the face. The mask may, as shown in Figure 1, comprise within it a source of electrical energy 100. The electrical power source 100 may, for example, be a battery or accumulator. The electrical power source 100 is for example a flat and flexible battery type Enfucell. A housing can be made within the mask to receive the source of electrical energy 100. This housing is for example cut into the thickness of one or more layers of the nonwoven.

The electrical energy source 100 may comprise: an electrical terminal connected to the conductive tracks 16, 17, 18 and 19; an electrical terminal connected to the counter-electrode 14. When the mask is in place on the face, the counter-electrode electrode 14 is held in the person's hand.

The supply of the electric current to the electrodes 11, 21, 31 and 41 can be effected via the conductive tracks 16, 17, 18 and 19. These can, for example, be metallic or formed by a conductive ink. .

The electrodes 11, 21, 31, 41 may be metallic or not. They may comprise, for example, silicones made conductive, metal fabrics or conductive polymers. Where appropriate, each electrode 11, 21, 31 and 41 is formed monolithically with its respective conductive track.

The electrical conductivity of the electrodes 11, 21, 31 and 41 may also be linked to the presence within it of an electrically conductive electrolyte, this electrically conductive electrolyte being able to impregnate a substrate which itself is electrically conductive or not. The outer surface of the mask may be defined at least partially, or totally, on the side opposite the skin, by an insulating support, which may extend over a larger area than the electrodes 11, 21, 31 and 41. The support insulation can help to secure the various underlying elements. This insulating support may be flexible and, for example, selected from films made of insulating thermoplastic material, for example films chosen from polyamides, styrenics, polyolefins or vinyls. The conductive tracks 16, 17, 18 and 19 may be formed by etching on the insulating support, or by screen printing or else be applied by transfer. Other methods for reporting the conductive tracks 16, 17, 18 and 19 on the insulating support are also possible. Table 1 below summarizes the assets delivered by each compartment of the mask of FIG. 1 and the polarity of the electrodes.

This mask comprises a nonwoven support 13 with four compartments: - two compartments 3 and 4 to cover the eye contour, - two compartments 5 and 6 to cover the cheekbones. Each compartment has an electrode 31, 41, 51, and 61.

It can be seen that the counter-electrodes 32, 42, 52 and 62 are arranged in each compartment 3, 4, 5 and 6 directly in front of the electrodes 31, 41, 51 and 61. In this case, the hands of the user are free. They do not hold a counter-electrode.

The mask may comprise a source of electrical energy 100 therein. The source of electrical energy 100 may include: an electrical terminal connected to the conductive tracks 16, 17, 18 and 19 and an electrical terminal connected to the conductive tracks 26, 27, 28 and 29. The supply of the electric current to the electrodes 31, 41, 51 and 61 can be effected via the conductive tracks 16, 17, 18 and 19. The supply of the electric current to the electrodes 32, 42, 52 and 62 can be effected via the conductive tracks 26, 27, 28 and 29.

An insulating layer may be interposed locally between the skin of the user and the electrode array. This insulating layer may make it possible to increase the comfort of the mask and to retain the source of electrical energy 100 and the network of electrodes within the mask. It also makes it possible to electrically isolate the energy source 100 from the skin of the user.

As in the example of Figures 1 and 2, the conductive tracks may cover only slightly the electrodes. Electric tracks may have other shapes than those shown. In particular, they may be branched. It is also possible that the conductive tracks have a substantially arcuate structure that better fits the shapes of the face.

Table 2 below summarizes the assets delivered by each compartment of the mask of Figure 2 and the polarity of the electrodes.

The mask is set up on the face. The user triggers his operation by a command button.

The duration of the treatment varies between 15 and 20 min, the limiting factor being the operating time of the battery. Once the treatment is finished, the mask is not reused but it could be otherwise. The invention is not limited to the examples which have just been described.

The exemplary embodiments of the illustrated examples may be combined with one another in non-illustrated variants. The structure of the electrodes and the surface they occupy in each compartment may in particular be different. The nature of the support, the number and the size of the compartments may be different. It is the same for the nature of the chemical compositions and the polarity of the electrodes. The phrase "with one" must be interpreted as synonymous with "having at least one" .5
