Description

1 COSMETIC ASSEMBLY AND METHOD OF COSMETIC TREATMENT

  The invention relates to a cosmetic assembly and a cosmetic treatment method for applying a cosmetic product having a different visual effect when it is exposed to daylight and when subjected to a source emitting radiation of wavelength. different, especially to a source of black light. For the purposes of the present invention, the term "cosmetic product" means a product as defined in Directive 93/35 / EEC of 14 June 1993 amending Directive 76/768 / EEC. By daylight is meant light from a natural or artificial light source emitting at a wavelength corresponding to the visible spectrum, namely between 405 and 700 nm. In the field of make-up, there are compositions which present a first rendering when they are subjected to daylight and a different rendering when they are subjected to a source emitting another type of radiation, for example a light source. black. However, when using such compositions, the user is not aware of the rendering of her makeup when subjected to such a black light source. However, it may be desirable to first be aware of the rendering of the makeup that will be obtained in such conditions, especially if a product which is not visible to the human eye when exposed to light is used. of the day. It is known, particularly from US5025354, US3619596, US4888667 and WO03090692, to use white light sources associated with makeup articles. Document KR9202038 discloses a housing provided with a fluorescent light source. However, such articles do not make it possible to visualize the effect of a cosmetic product capable of generating a different rendering when it is subjected to a radiation source emitting at a length of waves outside the visible spectrum. of its rendering when it is subject to daylight. This is why there is a need to produce a cosmetic assembly which makes it possible to facilitate the application of a cosmetic product presenting a visual rendition in the light of day and a different visual rendering when it is subjected to a source emitting different wavelengths. The invention thus has, according to one of its aspects, an assembly comprising: at least one radiation source emitting at wavelengths less than or equal to 405 nm or greater than or equal to 700 nm; - A cosmetic product comprising a compound capable of absorbing radiation from the radiation source and re-emitting radiation of different wavelengths and / or an applicator configured to apply a cosmetic product to the keratin materials. By associating a radiation source with a cosmetic product absorbing radiation from this source and retransmitting a radiation of wavelength different from the wavelengths to which the source emits or an applicator making it possible to apply such a product, it is possible to to the user who applies the product to visualize the rendering of this product under these lighting conditions. She can then if necessary improve the application and in particular adjust her makeup if the product is a makeup product.

  In particular, it is possible to choose a source which emits radiation in the UV spectrum, and in particular at wavelengths of between 10 and 405 nm, preferably between 280 and 405 nm.

  Preferably, the radiation source can emit at wavelengths between 365 and 405 nm, namely a radiation consisting mainly of violet and near ultraviolet, UVA type, which corresponds to black light.

The radiation source may comprise one or more electroluminescent diode (s). The use of diodes makes it possible not to increase the bulk of the cosmetic assembly. It is of course possible to use any other type of lamp which emits radiation of wavelength lying in the aforementioned range. The radiation source may be relatively directional so as to illuminate the area on which the cosmetic product is deposited. The angle of divergence of the radiation may for example be less than 40.

The radiation source may be arranged in such a way that, during the deposition of the product, the keratinous material on which the product is deposited is sent towards the zone. The user can then visualize the cosmetic product illuminated by the radiation source simultaneously with its application / diffusion on the zone to be treated. This facilitates the deposition of the product, especially when the latter is invisible to the naked eye when it is lit only by daylight. The cosmetic product may comprise a compound capable of absorbing radiation from the radiation source and re-emitting radiation with a wavelength of between 405 and 700 nm. The cosmetic product may for example comprise at least one fluorescent compound, and in particular at least one optical brightener.

For example, reference may be made to FR-A-2 741 261, which describes cosmetic compositions comprising optical brighteners for increasing the apparent intensity of the color of a nail polish, or at the request EP1 498 110 which describes hair dye compositions comprising fluorescent dyes and optical brighteners.

The product may exhibit color when subjected to a source emitting at wavelengths between 405 and 700 nm and a different color when irradiated from the radiation source provided in the assembly. cosmetic. The cosmetic product may not be visible to the naked eye when subjected only to a source emitting at wavelengths between 405 and 700 nm. The assembly may comprise a container containing the product.

According to one embodiment, the container may be pressurized. The assembly may then further comprise a diffusion device provided with a product diffusion orifice. The radiation source may in this case be arranged near the diffusion orifice. It is thus possible to see the visual rendering of the cosmetic product as it is spread over the area of the body on which it is deposited. When the assembly includes an applicator, the radiation source may be arranged to emit radiation toward the applicator. It is thus possible to see the rendering of the cosmetic product subjected to this radiation as it is applied to the area of the body to which it is applied. The container may be provided with an opening reversibly closed by a closure member carrying an applicator. The assembly may comprise a control member for controlling the actuation of the source (s) of radiation. The control member may be in the form of a thumb wheel, a push button or a touch pad. This control member can make it possible to turn on the source of radiation but also to turn it off. As a variant, or in addition, an electrical circuit can be provided which makes it possible to extinguish the radiation source after a predefined duration. The assembly may also include a radiation intensity adjusting member. This adjustment member may for example drive a potentiometer. The cosmetic product may be a product intended to be applied to the nails or to the skin, in particular the skin of the face, the eyelids, the eye contour, the body, the product being, in particular, a foundation, a blush 2908965 5 or eyelids. The cosmetic product may also be a product intended to be applied to keratin fibers, in particular eyelashes, eyebrows or hair, or a product intended to be applied to the lips, such as a lipstick or lip gloss. According to one embodiment, the applicator may be arranged to apply the product to the eyelashes, and may comprise in particular a brush or a comb. According to another embodiment, the applicator may comprise a brush 10 for application to the nails, lips or skin, or a tip, in particular a flocked tip. The applicator may also comprise an elastically compressible member, in particular a foam and / or an elastomer, possibly flocked, or comprise a felt or a ball. Alternatively, the product may be in the form of a stick or in the form of a patch, the assembly no longer necessarily comprising an applicator. When the product is in stick form, the radiation source may be disposed on the container so as to emit radiation towards an application end of the stick. The subject of the invention is also a cosmetic treatment method in which a cosmetic product 25 comprising a compound capable of absorbing radiation originating from a radiation source emitting at wavelengths less than or equal to 5 hours in length is applied to keratin materials. 405 nm or greater than or equal to 700 nm and re-emitting radiation of different wavelength and, simultaneously or subsequently, subjecting the treated zone of keratin materials to a source emitting at wavelengths less than or equal to 405 nm. nm or greater than or equal to 800 nm.

The invention can be better understood on reading the following detailed description, non-limiting examples of implementation thereof, and on examining the appended drawing, in which: FIG. 1 is a perspective view of a first embodiment of an assembly according to the invention comprising a container and an applicator provided with a radiation source; FIGS. 1A and 1B show different forms of applicators that can be used; in the whole of FIG. 1, FIGS. 2 and 3 show perspective views of other embodiments of an assembly according to the invention comprising a container and an applicator provided with a source of radiation, - Figures 4 and 5 show perspective views of other embodiments of an assembly according to the invention comprising a cosmetic product and a radiation source; FIGS. 6 and 7 are perspective views of other embodiments of an assembly according to the invention comprising a housing containing a cosmetic product, the housing being provided with a source of radiation, and FIG. 8 is a perspective view of an assembly according to the invention having a pressure vessel containing a cosmetic product, the container being provided with a radiation source. The assembly according to the invention which will be described in detail comprises one or more sources of radiation emitting outside the visible spectrum and a cosmetic product to be applied or distributed, possibly associated with an applicator configured to apply a cosmetic product to keratin materials. Alternatively, the assembly may comprise one or more sources of radiation emitting outside the visible and only an applicator configured to apply a cosmetic product on keratin materials. The radiation source or sources emit in particular at wavelengths less than 405 nm or greater than 700 nm, namely in the spectrum of UV or IR. This source is intended to reveal to the human eye a visual appearance of the product that is not visible when exposed only to daylight.

For example, one or more wavelength radiation sources of between 365 and 405 nm, namely a black light source, are selected. The cosmetic product may, for example, not be visible to the naked eye when it is not illuminated by a source other than daylight and appear colored when illuminated by the chosen radiation source. The cosmetic product may also appear in a certain color in the light of day and a brighter color or another color when illuminated by the chosen radiation source.

For this purpose, the cosmetic product comprises at least one compound capable of absorbing the radiation originating from the radiation source and to be reemitted in the visible. This is for example a makeup product, a hair product or a facial or body care product.

A first family of compounds capable of absorbing radiation from a source of UV radiation and to be reemitted in the visible corresponds to optical brighteners. These are compounds well known to those skilled in the art. Such compounds are described in "Fluorescent Whitening Agent, Encyclopedia of Chemical Technology, Kirk-Othmer", Vol 11, p. 227-241, 4th edition, 1994, Wiley. They can more particularly be defined as compounds which absorb essentially in the UVA between 300 and 390 nm and re-emit essentially between 400 and 525 nm. Among the optical brighteners, mention may be made more particularly of stilbene derivatives, in particular polystyrylstilbenes and triazinylstilbenes, coumarin derivatives, in particular hydroxycoumarines and aminocoumarines, oxazole, benzoxazole, imidazole, triazole and pyrazoline derivatives, pyrene derivatives and porphyrin derivatives and mixtures thereof. For example, mention may be made of: the stilbene derivative of naphtho-triazole sold under the trade name Tinopal GS, di-styryl-4,4 'biphenyl disulphonate di-sodium (CTFA name: disodium distyrylbiphenyl disulphonate) sold under the trade name Tinopal CBS-X, the cationic derivative of aminocoumarin sold under the trade name Tinopal SWN CONC. sodium 4,4'-bis [(4,6-dianilino-1,3,5-triazin-2-yl) amino] stilbene-2,2'-disulfonate sold under the trade name Tinopal SOP, 4,4 Bis - [(4-anilino-6-bis (2-hydroxyethyl) amino-1,3,5-triazin-2-yl) amino] stilbene-2,2'-disulfonic acid sold under the trade name Tinopal UNPA -GX, 4,4'-bis- [4-anilino-6-morpholine-1,3,5-triazin-2-yl) amino] stilbene sold under the trade name Tinopal AMS-GX, 4,4 Bis - [(4-anilino-6- (2-hydroxyethyl) methylamino-1,3,5-triazin-2-yl) amino] stilbene-2,2'-disodium sulfonate sold under the trade name Tinopal 5BM GX, all by the company CIBA Specialty Chemicals, 2,5 thiophene di-yl bis (5-tert-butyl-1,3-benzoxazole) sold under the trade name Uvitex OB by the company Ciba, the anionic derivative of di-aminostilbene dispersion in water sold under the trade name Leucophor BSB liquid by the company Clariant, - az lacquers Optical medium sold under the trade name COVAZUR by the company WACKHERR. Some optical brighteners may also be in the form of copolymers, for example acrylates and / or methacrylates, grafted with optical brightening groups as described in application FR99-10942. A second family of compounds capable of absorbing radiation from a source of UV radiation and reemitting in the visible corresponds to fluorescent dyes.

It should be noted that the fluorescent dyes are more precisely compounds chosen from those which absorb light in the visible part of the spectrum and possibly in the ultraviolet zone, and reemit fluorescent light in the visible spectrum, longer wavelength than absorbed light. Preferably, the wavelength of the light re-emitted by the fluorescent dye is between 500 and 650 nm. Fluorescent dyes for hair dye products are chosen in particular from naphthalimides; cationic and non-cationic coumarins; xanthenodiquinolizines; azaxanthenes; naphtholactams; azlactones; oxazines; thiazines; dioxazines, pyrenes, nitrobenzoxadiazoles, alone or in mixtures. The optical brightener which may be present in the hair coloring composition is more particularly chosen from compounds which absorb light in the ultraviolet part of the spectrum, essentially in the UVA, at a wavelength of between 300 and 390 nm. These compounds re-emit a fluorescent light in the visible spectrum, between 400 and 525 nm.

Referring now to the figures, several embodiments of assemblies according to the invention which comprise cosmetic compositions as defined above can be seen.

In particular, with reference to FIG. 1, it is possible to see a cosmetic assembly 10 which comprises a bottle 20 containing a cosmetic product and in particular a nail polish, the bottle being closed by a cap 30 carrying an applicator 40 in the form of a brush.

The bottle 20 comprises a body 21 forming a reservoir, the body being closed by a bottom 22 at the bottom and ending with a neck 23 open at the top. The neck 23 is threaded on its outer surface to allow the cap 30 carrying the applicator to screw on and close the bottle.

The cap 30 has an inner skirt 31 threaded on its inner surface to cooperate with the neck 23 of the bottle, and an outer cylindrical skirt 32, surrounding the inner skirt, the two skirts being connected in the upper part to a transverse wall. A shank 41 at one end of which is attached a tuft of bristles 42 forming a brush extends from the transverse wall at the center of the threaded skirt. Two light-emitting diodes 50 are provided between the outer skirt and the inner skirt of the cap, the diodes being oriented parallel to the rod 41 so as to emit radiation in the direction of the tuft of bristles 42 of the brush. The two diodes 50 are diametrically opposed so as to distribute the radiation around the rod. It can of course provide more than two diodes distributed between the two skirts so as to obtain a more uniform illumination. In a variant, it is also possible to provide only one diode.

The diodes can be chosen to emit a weakly diverging beam, which can make it possible to illuminate more intensively the zone to be visualized. The radiation has for example a divergence angle of about 30. The diodes emit, for example, radiation of wavelength equal to 380 nm. The cap 30 also houses a power supply for powering an electrical circuit for turning on the diodes. The power supply may comprise for example at least one button-cell, or several button-batteries connected electrically in series or any other arrangement, in parallel in particular, the power supply being possibly rechargeable.

To control the ignition of the diodes, a wheel 51 is provided in the upper part of the cap, the wheel rotatable between two positions, a first ignition position in which an electrical contact is made and a second position in which no contact electrical power is achieved so that the diodes are off. It can also be expected that the rotation of the wheel between these two positions is accompanied by a variation in intensity of the radiation, the wheel acting on a potentiometer for controlling the intensity of the diodes.

Alternatively, the control member of the diodes may be a push button or a touch pad. To apply the product, the user unscrews the cap 30 of the vial neck 20 by holding the outer skirt 32 of the cap, then turns the dial to turn on the diodes. The user can also unscrew the cap after first turning the knob. The cap 30 serves as a gripping member during the application of the brush. When she applies the nail polish to her nails, the user thus sees, as and when the application, the color of the varnish when her nails are lit by a black light. Alternatively, it can apply the nail polish composition without the diode is lit and turn the knob at the end of application to turn on the diode 20 and light up his nails already made up. In addition, if the nail polish is transparent when it is not illuminated by anything other than the light of the visible spectrum, and that it is for example white in the presence of black light, the user will be able to more easily know where she applied her product. The assembly illustrated in Figure 1, may optionally contain a lip makeup product, for example a gloss, instead of nail polish.

Instead of having a brush 40, the applicator of the assembly illustrated in FIG. 1 may alternatively comprise a brush 43 (FIG. 1A) or a comb 44 (FIG. 1B). The cosmetic product contained in the bottle can then be a mascara for makeup eyelashes or a hair coloring product to be applied to locks of hair.

The assembly 110 illustrated in FIG. 2 this time comprises a packaging of a classic mascara composition, namely an assembly which comprises a bottle 120 containing the mascara and a cap 130 carrying an applicator 140, this time formed by a rod 141. provided with a mascara brush 142. An insert member 150 is mounted clamping at the end of the cap opposite the brush, this member carrying a light emitting diode 154. The member 10 attached 150 comprises a cylindrical skirt 151 which is enclosed on the cap 130 by an open end 152, the opposite end having a push button 153 as an on / off switch. The free edge of the open end 152 of the cylindrical skirt is extended by a point 155 which carries a light-emitting diode 154 at its end. The diode is thus arranged so that the radiation is oriented in the direction of the brush 142. The insert member 150 also comprises a battery provided inside the cylindrical skirt for supplying an electrical circuit making it possible to switch on the light. 20 diode. The button 153 acting as an on / off switch can be inserted into the cylindrical skirt 151 between two positions, a first ignition position in which an electrical contact is made and a second position in which no electrical contact is made if although the diode 154 is off.

According to this embodiment, the insert member 150 carrying the diode may be removable. It can indeed be removed from the cap 130 of the bottle to be placed on another set when there is no more product in the bottle or if the user wishes to apply another makeup product containing a compound suitable for absorb the radiation from the black light source. To apply the product, the user unscrews the cap of the bottle by holding the outer skirt of the cap, then pushes the button 153 to light the diode. The user can also unscrew the cap after first pressing the button. The user can then apply the mascara composition to her eyelashes while the diode is lit so as to visualize rendering of the composition under black light as it is applied. Alternatively, it can apply the composition of mascara on its eyelashes without the diode is lit and push the button at the end of application to turn on the diode and light up his eyelashes already makeup. Instead of containing a mascara composition for makeup eyelashes, the bottle may contain a hair coloring product to be applied to strands of hair.

FIG. 3 shows an assembly 210 comprising a roll-on applicator which comprises a spherical ball 240, mounted free to rotate on itself at a first end of a tube 220 forming a product reservoir. The applicator may of course have a shape other than a sphere and / or be rotatably mounted about a single axis. The product can flow by gravity inside the tube towards the ball. By engaging a surface portion of the ball emerging outside with the surface to be treated, and by a suitable movement of the device relative to the surface, the ball is rotated on itself so that the portion the ball inside the container emerges outside, thus depositing the product on the surface to be treated. The second end of the tube opposite the first is closed. An insert member 250 similar to that just described in accordance with FIG. 2 is fitted on this end, except that the actuating member is no longer in the form of a button. push member sinking into the skirt, but is obtained by a relative rotational displacement of a central portion 253 relative to the skirt 251. The insert member 250 has in fact as previously a skirt 251 provided with a 255 bearing point a diode 254, the skirt 251 being open at its end opposite to that carrying the diode. A central portion 253 is partially housed inside the skirt 251 and axially protrudes the skirt so as to define a zone accessible by the user. The central portion 253 is this time fixed axially relative to the skirt 251 but can be moved in rotation relative to the skirt between at least two positions, a first position in which no electrical contact is made so that the diode is extinguished and a second ignition position in which an electrical contact is made which allows the diode to illuminate. It can also be expected that the rotation of the central portion between these two positions is accompanied by a variation in intensity of the radiation, the central portion 253 acting on a potentiometer for controlling the intensity of the diode. Instead of being packaged in a tube and being applied by means of a ball 15 as in FIG. 3, the product may be in the form of a pencil 340. Such an assembly 310 illustrated in FIG. apply an eyeliner for example. FIG. 5 represents a lipstick tube 410 in the form of a stick. The product is in the form of a stick 440, also called product grape. The assembly 410 comprises a tubular case 420 in which is mounted a cup holder stick, capable of sliding axially in the case, the base of the solid stick of solid product is engaged in the cup. The assembly further comprises drive means in the form of a rotating wheel 421, whereby the user can slide the cup into the case to pull out or retract the stick at will. After use, the assembly is closed using a cap 460 held fixed on the case. According to this embodiment, the case 420 comprises a recess 422 in which are provided two electroluminescent diodes 450 which are oriented so as to emit radiation in the direction of the stick of product, and in particular of its applicator end. Preferably, the two diodes are diametrically opposed on the tube so as to distribute the radiation around the product stick.

An upright actuator 430 is also provided on the recess 422. When the cap 460 is removed from the holster, the pushbutton 430 is in a position in which an electrical contact is made. so that the diodes are lit. When fixing the cap on the case, the free edge 461 of the cap pushes the push button 430 which prevents any electrical contact. The diodes are therefore automatically ignited each time the cap is removed.

Alternatively, there may be provided an actuating member in the form of a pushbutton or a touch pad disposed on another part of the case and which is manually operated. Figures 6 and 7 show makeup cases 510 and 610 respectively, which have a base portion 520 and 620 and a cover 560 and 660, the cover may include a mirror 570, 670. The base portion has a plurality of compartments 521 and 621 containing different products.

For example, it is possible for the housing to include patches for making tattoos. Patches may, for example, not be visible when exposed only to visible light and appear when exposed to radiation from a black light source.

The casings may also include any other cosmetic product, especially in the form of a compacted powder. Two light-emitting diodes 550, 650 may for example be provided in the housings, in particular in the base part.
