    £> 4) AEROSOL DEVICE FOR DRY WASHING AND HAIR TREATMENT.
    FR 3,063,607 - A1 (hj> The present invention relates to an aerosol device comprising:
    a container containing a cosmetic composition which comprises at least 6% by weight of one or more powders relative to the total weight of the composition, and
    a dispensing head comprising a body and an end portion comprising at least two outlet orifices configured to allow spraying of the composition around a longitudinal axis of the end portion in at least two different directions, the head dispenser comprising at least first and second chambers successively traversed by the flow of composition before its exit through the outlet orifices.
    AEROSOL DEVICE FOR DRY WASHING AND HAIR TREATMENT
    The present invention relates to a particular aerosol device comprising a cosmetic composition based on at least one powder, and its use for dry washing and cosmetic treatment of keratin materials, preferably human keratin fibers such as hair.
    In the field of washing keratin materials, dry shampoos have existed for many years, either in powder form or in aerosol form. They quickly remove excess sebum without wetting the hair. They act by capturing sebum by absorption thanks to powders chosen for their absorbent qualities of sebum.
    The powders used can be of mineral, organic, natural or synthetic origin and can be derived from wheat starch, rice and corn.
    In practice, the dry shampoos offered are not entirely satisfactory, in particular in terms of application and comfort. The aerosol sprays conventionally used generate a conical spray. This type of spray is not optimal for localized application, especially at the root level and is generally uncomfortable on application due to the fairly high impact force on the hair.
    Aerosol devices comprising three outlet orifices have already been proposed for dispensing dry shampoos, in particular in patent application EP2991612, the three orifices spraying the composition in the same direction.
    Applications US2002 / 0017575 and EP2444160 describe spraying devices comprising one or more spraying rods pierced by orifices allowing the diffusion of a product in the hair.
    There is a need to further improve aerosol devices comprising a composition of a dry shampoo.
    The Applicant has surprisingly and advantageously found that the use of a device provided with a dispensing head comprising at least two outlet orifices making it possible to spray the composition in at least two different directions and at least two crossed chambers successively by the flow of composition before its exit through the outlet orifices to distribute a composition comprising a powder made it possible to facilitate the application of the composition with better dispersion, thanks to an application in several preferred directions, and to offer more comfort on application, especially at the root while offering the cleaning properties expected from a dry shampoo.
    Changes in the direction of the flow of the composition in the dispensing head make it possible to create turbulence in the flow of composition, which makes it possible to obtain good quality sprays.
    The object of the invention is, according to a first of its aspects, an aerosol device comprising:
    - a container containing a cosmetic composition which comprises at least 7% by weight of one or more powders relative to the total weight of the composition, and
    a dispensing head comprising a body and an end portion comprising at least two outlet orifices configured to allow spraying of the composition around a longitudinal axis of the end portion in at least two different directions, the head dispenser comprising at least first and second chambers successively traversed by the flow of composition before its exit through the outlet orifices.
    This particular combination allows comfort to be applied by spraying directly under the hair.
    It also facilitates application by distributing the hair composition at the level of the hair roots in an optimal manner, and thus makes it possible to provide efficient cleaning.
    Furthermore, the composition leaves less white residue.
    It is also possible to obtain a styling effect, in particular for providing volume and texturing to the hair and detachment of the roots.
    The present invention also relates to a dry washing and hair treatment method, comprising the implementation of the device as defined above. In particular, the method comprises a step of spraying, using the aerosol device according to the invention, onto the keratin materials, the composition according to the invention.

    By sebum absorbing powder, is meant within the meaning of the present invention a powder capable of absorbing and / or adsorbing sebum which has a sebum uptake greater than or equal to 35 ml / 100 g.
    The sebum intake corresponds to the amount of sebum absorbed and / or adsorbed by the powder. It is expressed in ml of sebum per 100 g. powder and measured using the powder oil determination method described in standard NF T 30-022.
    The powder oil intake corresponds to the amount of sebum absorbed on the available surface of the powder by measuring the "Wet point" as indicated below.
    The measurement method is as follows: a quantity m (in grams) of between 0.5 and 5 grams of powder is placed on a glass plate, the quantity depending on the density of the powder, and then dropwise added artificial sebum having the following composition:
    - Trioleine 29% by weight - Oleic acid 28.5% by weight - Oleyl oleate 18.5% by weight - Squalene 14% by weight
    - Cholesterol 7% by weight - Cholesterol palmitate 3% by weight
    After adding 4 to 5 drops of artificial sebum, incorporate the artificial sebum into the powder using a spatula and continue adding artificial sebum until the formation of artificial sebum and powder conglomerates. From this point, add the artificial sebum one drop at a time, and then triturate the mixture with the spatula.
    We stop adding artificial sebum when we get a firm and smooth paste. This paste should be allowed to spread on the glass plate without cracks or lump formation. The volume Vs in ml is then noted of the artificial sebum used.
    The sebum uptake corresponds to the Vs / m ratio.
    The absorbent powder (s) of sebum used in the aerosol device of the invention preferably has a sebum uptake, ranging from 35 to 1000 ml / 100 g, better still from 35 at 800 ml / 100 g.

The BET specific surface corresponds to the total specific surface (therefore micropores included) of the particle, and in particular of the powder.
    The sebum absorbing powder can be a mineral powder or an organic powder.
    More specifically, the absorbing sebum powder can be chosen from:

    Those skilled in the art will take care to choose these possible additives and their amounts so that they do not harm the properties of the compositions of the present invention.
    The compositions according to the invention are packaged in an aerosol device comprising a container, also called a reservoir.
    The container is pressurized and contains the composition to be delivered. As already mentioned above, the container contains both the propellant (s) and the other ingredients of the composition, in a single compartment, or alternatively in two compartments. According to this latter variant, the container can be constituted by an external aerosol reservoir comprising an internal pocket hermetically welded to a valve. The various ingredients of the composition are introduced into the internal pocket and a propellant is introduced between the pocket and the container at a pressure sufficient to release the composition in the form of a spray.
    The propellant can be a compressed gas preferably used at a pressure between 1 and 12 bars, better still between 9 and 11 bars.
    The container is equipped at its upper end with a valve ensuring the tightness of the system. The valves suitable for the devices according to the invention are in particular valves having an internal restriction orifice of between 0.3 and 3 mm, preferably between 0.5 and 2.5 mm, and even more preferably between 0.6 and 1 mm. As a variant, these valves may not have an internal restriction orifice. The valves may have a nozzle with at least one orifice, better still two orifices of a size between 0.3 and 1 mm, preferably between 0.4 and 0.8 mm, and even more preferably between 0.5 and 0 , 7 mm. They can also be fitted with an additional gas outlet (PGA).
    These are, in particular, "powder" valves sold by the companies PRECISION, COSTER, SEAQUIST and LINDAL.
    The device, packaged with such a valve, ensures the tightness of the system, as well as the distribution of the composition from the container.
    The aerosol device according to the invention also comprises a dispensing head comprising a body and an end part, in particular a diffuser, which can be attached to the body. The end part comprises at least two outlet orifices configured to allow spraying of the composition around a longitudinal axis Y of the end part in at least two different directions, which can in particular be diametrically opposite, the head of distribution comprising at least first and second chambers, successively traversed by the flow of composition before its exit through the outlet orifices.
    The first and second bedrooms can be concentric.
    At least one opening between the first and second concentric chambers can be angularly offset with respect to at least one of the outlet orifices. This angular offset must be understood as being an offset around the axis of the concentric chambers or the axis of the device, for example.
    Thus, the composition flow leaving the diffuser has notably undergone at least two changes of direction of the flow in the diffuser, or even at least three changes of direction. By “change of direction”, it should be understood that the flow of composition passes from a first direction to a second direction, the two directions making between them an angle preferably greater than 60 °, or even greater than 90 °, better greater than 120 °, or even greater than 150 °. In an exemplary embodiment, the composition flow undergoes at least one change of direction greater than 120 °, or even greater than 150 °, better on the order of 180 °.
    The body and the end piece can define when assembled several outlet orifices around a longitudinal axis Y of the end piece, in particular in at least two different directions, which are in particular diametrically opposite. Alternatively, the dispensing orifices can be provided directly in the diffuser. They can be arranged in a curved portion of the diffuser, for example of hemispherical shape.
    By the use of the expression “end part”, it is not excluded that the end part may include an insert defining the end of the dispensing head.
    The concentric chambers can be at least partially annular, even annular. The dispensing head may in particular comprise a first interior chamber and a second exterior chamber. The interior and exterior rooms can be separated by a separation skirt. This skirt can provide a seal for the rooms.
    This separation skirt can be pierced with at least one opening, or even at least two openings, allowing the flow of the composition flow. Thus, the composition stream can be separated into at least two separate streams. The openings in the separation skirt can be distributed evenly around the periphery of the separation skirt. They may for example be diametrically opposite when they are two in number. Their number can be between 2 and 10.
    The second chamber can be surrounded by a peripheral skirt cooperating with the body so as to ensure the closure of the second chamber.
    The outlet orifices can be evenly distributed around the periphery of the peripheral skirt. They are for example diametrically opposite when they are two in number. Their number can be between 2 and 10. They can be diametrically opposed two by two.
    The dispensing head can be configured to allow spraying of the composition by outlet orifices in at least one direction transverse to a longitudinal axis Y, in particular in at least two different directions, which are in particular diametrically opposite,
    The outlet orifices may be coplanar and arranged in a plane inclined with respect to the longitudinal axis X. The dispensing head may in particular comprise at least three coplanar outlet orifices, the directions of spraying being in particular arranged at least 30 °, or even at least 60 °, or even at least 90 ° from each other.
    The outlet orifices can be angularly offset with respect to the opening or openings of the separation skirt, each at an angle of between 0 and 180 °, better between 20 and 90 °, better between 30 and 80 °, for example by 'around 45 °.
    The longitudinal axis Y of the diffuser can constitute an axis of symmetry of the diffuser.
    The diffuser is preferably assembled with the body from above it. The diffuser can define the upper axial end of the dispensing head.
    The end part, in particular the diffuser, may have an upper face of generally convexly convex outward shape.
    The dispensing head may have a channel for supplying the composition from the container. To this end, the body has a central channel intended to allow the flow of the composition flow from the container to the diffuser.
    The body can define a cannula traversed by said channel, this cannula being of longitudinal axis inclined relative to the longitudinal axis X of the container.
    The central channel of the body may comprise a vertical portion, extending in the longitudinal axis X of the device above the container, and an oblique portion, inclined at an angle y with respect to the vertical portion. The angle γ can be between 0 and 90 °, better between 5 and 40 °, or even between 10 and 30 °, being for example of the order of 15 °. The oblique portion of the central channel can receive the diffuser.
    The vertical portion of the central channel is intended to receive the stem of the container dispensing valve.
    The device can be devoid of a nozzle with vortex channels, which simplifies its production. The dispensing orifices can preferably be with direct outlet, without attached nozzle. By attached nozzle is meant a part having at least one outlet orifice and comprising a flat wall in which the outlet orifice is provided, as well as a mounting skirt, which can be mounted on a centerpost.
    Each jet exiting the diffuser can be oriented generally along an axis not parallel to a longitudinal axis X of the device, in particular obliquely, being for example inclined relative to the longitudinal axis of the device by an angle greater than 10 °, better greater than 20 °, even better above 30 °.
    The outgoing flow from each outlet can be oriented perpendicular to the axis Y of the diffuser, the outlet holes being for example coplanar and axes oriented perpendicular to the axis Y of the diffuser.
    As a variant, the jet exiting from each outlet orifice can make an angle with the normal to this axis Y, so that all the jets produce a spray resulting from a substantially conical shape. This angle can be non-zero, between 5 and 180 °, better between 10 and 90 °, or even between 20 and 80 °, better between 25 and 70 °, being for example of the order of 35 °.
    The device can comprise at least three outlet openings, better still at least four outlet openings which are preferably non-aligned. The distance between the most widely spaced outlets may be less than 25 mm, better still less than 20 mm, or even less than 15 mm, being for example of the order of 12 mm or 10 mm.
    The distribution of the composition can be started by tilting the body relative to the container.
    The invention also relates to the use of the device as described above for spraying a composition up to 360 °.

    FIGS. 1 to 11 show a device 1 for spraying a composition comprising a container 2 containing the composition to be sprayed, and a dispensing head 3 covering the container 2. The initial pressure in the container is for example between 1 and 12 bars at 20 ° C.
    The container 2 may include a valve holder cup, not shown, crimped onto a body of the container or produced otherwise.
    The dispensing head 3 comprises a body 5 disposed on the container 2 and cooperating with a diffuser 7. A closure cover 9, visible in Figures 3 and 4, is intended to cover the body 5 and the diffuser 7 in the absence of use. The cover 9 comprises for example an annular relief 10 to allow its maintenance on the container 2 by snap-fastening.
    The body 5 and the diffuser 7 are configured to allow spraying of the composition in at least two different directions, which in the example described are four in number, distributed around the axis Y of the diffuser. To this end, the diffuser 7 has four outlet orifices 12, visible in FIGS. 8 to 10, which will be detailed below.
    During the spraying of the composition, the flow of composition coming from the container firstly circulates in a central channel 25 of the body 5, intended to allow the composition to pass from the container 2 to the diffuser 7. This central channel 25 comprises a straight portion 25a, extending in the longitudinal axis X of the device above the container, and an oblique portion 25b, extending along the axis Y of the diffuser 7, and which is inclined at an angle γ with respect to the straight portion 25a. The angle γ is for example of the order of 20 to 30 °.
    The diffuser 7 comprises a central rod 28 allowing its attachment to the body 5, in the oblique portion 25b. The fixing is done by force insertion and snap-fastening. The central rod 28 for this purpose comprises a fixing relief 30 such as an annular bead intended to snap behind a corresponding relief of the body 5.
    The central rod 28 has a shoulder 34 in order to guarantee sealing.
    Two longitudinal grooves 32 formed on the central rod 28 allow the composition of the body 5 to pass to the diffuser 7. In the example described, they are diametrically opposite. These grooves 32 are oriented along the axis Y of the diffuser. They may be of partially circular cross section.
    In the diffuser 7, the flow of composition circulates in a first interior chamber 15 and a second exterior chamber 16 concentric with the first.
    The diffuser 7 comprises a separation skirt 18 between the first and second chambers 15 and 16. This separation skirt 18 is pierced with two openings 20 allowing the flow of the composition flow. Thus, the latter is separated into four separate streams, including two opposite streams leaving each of the openings 20. The latter are equally distributed around the periphery of the separation skirt 18, being diametrically opposite. Each opening 20 preferably extends over the entire height h1 of the separation skirt 18, as illustrated in FIG. 11. The height h1 of the separation skirt 18 is for example of the order of 2.5 or 4 mm.
    The second chamber 16 is surrounded by a peripheral skirt 22 of the diffuser 7, cooperating with the body 5, so as to ensure the closure of the second chamber 16. The peripheral skirt 22 has the four aforementioned outlet orifices 12 for ensuring the exit of outward composition. These outlet orifices 12 are equally distributed around the axis Y of the diffuser 7. They can each extend over the entire height h2 of the peripheral skirt or over only a part of the latter. This height h2 can be of the order of 1.9 or 5 mm.
    The chambers 15 and 16 preferably have respective widths 11 and I2 of the order of 1.2 mm.
    The outlet orifices 12 may comprise a lower portion in the form of a slot of constant width formed in the bottom of the skirt 22, and an upper portion of semi-circular cross section, formed in the top of the skirt 22, extending to part of the shoulder 22a. The composition leaves the device through the upper portion of the outlet orifices 12, the lower portion being concealed and closed off by the body 7.
    The outlet orifices may each have a section of between 0.05 and 5 mm 2 , better still between 0.1 and 2 mm 2 , for example of the order of 1 mm 2 .
    The outlet orifices can have any suitable geometric shape. In one embodiment, they can be of circular cross section.
    The outlet orifices 12 are angularly offset relative to the openings 20 of the separation skirt 18. They are for example each offset by an angle a of the order of 45 °, as illustrated in FIG. 10.
    The openings 20 are offset relative to the longitudinal grooves 32. They are for example offset by an angle β on the order of 90 °, as also illustrated in FIG. 10.
    The body 5 comprises an annular groove 23 intended to receive the peripheral skirt 22 of the diffuser 7. This annular groove 23 is delimited by two concentric ribs 24a and 24b, configured to engage on either side of the peripheral skirt 22. The two ribs 24a and 24b are continuous. They can come to bear against shoulders 22a and 18a respectively present on the separation skirts 18 and peripheral 22, when the body and the diffuser are assembled. They are preferably of respective thicknesses e1 and e2 of the order of 0.7 mm. They make a gap of about 1.25 mm between them. The rib 24b blocks the lower portion of the outlet orifices 12.
    The annular groove 23 and the ribs 24a and 24b are arranged at one end of the body, opposite to a mounting skirt 27 of the body 5 on the container 2. The rest of the body, and in particular the central channel 25 of the body, is connected by a hinge 27a to the mounting skirt 27. The mounting skirt is preferably snap-fastened to the container, but can also be fixed otherwise to the latter.
    The diffuser 7 has an upper face 35 of generally convex shape, the radius of curvature of which is for example of the order of 6 mm.
    The upper face 35 of the diffuser 7 has marks in the form of reliefs 36, of generally triangular shape, the point of which is oriented towards the edge of the upper face 35 and towards the peripheral skirt 22 in alignment with the outlet orifices 12. The upper end 35 of the diffuser 7 also has a central depression 37, of circular outline, which houses the injection core.
    The composition flow undergoes at least two changes of direction in the diffuser 7. The composition flow thus passes, as illustrated in FIG. 9, from a first direction A in the grooves 32 to a second direction B in the first chamber 15 , the two directions A and B making an angle of 90 ° between them. The flow of composition then passes from direction B to a direction C in the second chamber 16, with a change of direction of the order of 180 °, then takes a direction D which corresponds to the exit of the composition through an orifice of exit 12.
    We will now describe with reference to Figures 12 to 21 an alternative embodiment. In this example, the outlet orifices 12 are formed in the diffuser 7 directly. They are formed in a curved portion of the diffuser 7, of hemispherical shape, having a radius of curvature of about 6 mm.
    The orifices 12 are oriented towards the outside each along an axis Z which forms an angle δ with the axis Y of the diffuser. The angle δ is less than 90 °, so that the resulting spray is conical, with a distribution of the composition all around the axis Y. The angle δ can be between 10 and 85 °, better between 20 and 80 °, being for example between 30 and 75 °, or even between 40 and 70 °. It can for example be around 60 °.
    The dispensing head of FIGS. 12 to 21 also differs from that of FIGS. 1 to 11 by the shape of the body 5. The latter comprises, in this embodiment, a cannula 25b traversed by said channel 25, this cannula being of longitudinal axis Y inclined with respect to the longitudinal axis X of the container.
    In addition, the mounting skirt 27 of the body 5 on the container 2 is connected to the rest of the body by a hinge 27a situated relative to the longitudinal axis X on the same side as the inclination of the axis Y, so that the longitudinal axis Y of the cannula of a movable part of the body 5 is substantially parallel to the longitudinal axis X of the container during the distribution of the composition.
    The invention is not limited to the examples which have just been described.
    For example, the valve of the container can be triggered by pressing and not by tilting.
    The number of exit ports can be changed, as well as their orientation.
    The axes of the outlet orifices, according to which the sprays are emitted, can be coplanar or not, or contained in the same cone of axis Y or not.
    The present invention also relates to a method of dry washing and cosmetic treatment of the hair, comprising the application to the hair, preferably dry, of a cosmetic composition as described above by means of an aerosol device such as described above.
    The application of the composition may or may not be followed by rinsing after a possible exposure time, in the presence or not of heat. Preferably, the application is not followed by rinsing.
    The application of the composition can be followed or not by brushing after a possible exposure time, in the presence or not of heat.
    The present invention also relates to the use of the cosmetic composition defined above sprayed from the aerosol device according to the invention for dry washing and cosmetic treatment of the hair.
