Definitions

  • the present invention relates to a device for spraying an anti-sun cosmetic product onto a keratin support, in particular the skin.
  • UV-A rays with wavelengths of between 320 and 400 nm penetrate more deeply into the skin than UV-B rays. UV-A rays bring about immediate and persistent tanning of the skin. Daily exposure to UVA rays, even of short duration, under normal conditions can result in damage to the collagen fibres and the elastin, which is reflected by a modification to the microrelief of the skin, the appearance of wrinkles and uneven pigmentation (liver spots, heterogeneity of the complexion).
  • UVA and UVB radiation Protection against UVA and UVB radiation is therefore necessary.
  • An effective photoprotective product must protect against both UVA and UVB radiation.
  • Many photoprotective compositions have been proposed to date to overcome the effects induced by UVA and/or UVB radiation. They generally contain organic UV-screening agents and/or inorganic UV-screening agents, which function according to their own chemical nature and according to their own properties by absorption, reflection or scattering of the UV radiation. They generally contain mixtures of liposoluble organic screening agents and/or water-soluble UV- screening agents.
  • the anti-sun products presented in spray form are increasingly desired by consumers, due to their ease-of-use and their cosmetic pleasantness.
  • anti-sun compositions in spray form that have a high protection factor.
  • anti-sun products In order for anti-sun products to perform well they must form a uniform and continuous film on the skin. If they are packaged in bottles or in pump sprays, they must be spread with the fingers. The uniformity of the product is not then guaranteed. Furthermore, they leave an unpleasant greasy residual film on the hands after application.
  • Some cosmetic products are packaged in sealed containers, for example provided with added-on stoppering means, attached for example by snap- fastening to the container.
  • the product is poured directly onto the keratin support, or firstly onto the hands then onto the support, from the container.
  • airbrushes for spraying various anti-sun cosmetic products.
  • Conventional airbrushes comprise a body, which may be in the general shape of a gun or a pen, some of which are provided uppermost with a cup into which the product to be sprayed is poured.
  • Such airbrushes are referred to as "gravity-feed” airbrushes.
  • the presence of a cup permanently fixed to the body of the airbrush, into which the product is poured results in many handling operations during the filling and cleaning of the airbrush, which are often accompanied by wastage of the product. These handling operations are moreover a nuisance during the use of a product intended to avoid contact with the environment, such as an air-sensitive or irritant product.
  • Airbrushes referred to as siphon-feed airbrushes also exist, in which the product is contained in a container that is coupled, with its neck pointed upwards, to the body of the airbrush after having filled it, the airbrush comprising a dip tube that extends to the bottom of the container.
  • the siphon- feed versions result in tedious handling operations in order to clean the container between two uses.
  • the ergonomics of these airbrushes is worse than that of airbrushes with a gravity cup since the presence of the dip tube is capable of hampering the user in certain situations, for example when the airbrush must be handled around the face or the head of a person for example.
  • Siphon-feed airbrushes are the subject of patents US 1 638 550 and US 1 703 219.
  • Application US 2009/0090297 gives examples of siphon-feed and gravity- feed airbrushes.
  • Application EP 1 470 867 A2 describes an airbrush in which the product to be sprayed is contained in a container that may be removably attached to the body of the airbrush.
  • This container is provided with a valve that closes when the container is not in place and that opens after attachment of the container to the airbrush.
  • the use of a valve although it has advantages by reducing the exposure of the product to the environment, leads to a specific construction of the container, which increases its cost. Furthermore, certain products are capable, by drying or due to their particulate filler, of hampering the correct operation of the valve, for example by causing the latter to get stuck in the closed or open position.
  • Application US 2007/0090206 A1 discloses an airbrush comprising a housing for receiving a container that is removably attached to the airbrush.
  • the container comprises a valve, which poses the same problem as mentioned above.
  • the uptake of air takes place on the same side as that through which the product is sucked up, owing to a capillary passage made along an end fitting configured in order to act on the valve and that engages in the opening of the container.
  • a volatile compound selected from C1 -C4 monoalcohols, volatile oils, and mixtures thereof; d) hydrophobic silica aerogel particles,
  • composition having a dynamic viscosity at 25°C of less than 0.55 Pa.s, the air pressure at the airbrush intake port being greater than 0.2x10 5 Pa.
  • a spray system comprising an airbrush and an anhydrous composition comprising, in particular in a physiologically acceptable medium, at least:
  • a volatile compound selected from C1 -C4 monoalcohols, volatile oils, and mixtures thereof;
  • composition having a dynamic viscosity at 25°C of less than 0.55 Pa.s, the air pressure at the airbrush intake port being greater than 0.2x10 5 Pa.
  • the invention also relates to a non-therapeutic cosmetic method for limiting the darkening of the skin and/or improving the colour and/or the uniformity of the complexion, comprising the use of the spray system as defined above and the application of the composition to the surface of the keratin material.
  • the invention also relates to a non-therapeutic cosmetic method for preventing and/or treating the signs of ageing of a keratin material, comprising the use of the spray system as defined above and the application of the composition to the surface of the keratin material.
  • physiologically acceptable medium is intended to denote a medium that is suitable for the topical administration of a composition.
  • a physiologically acceptable medium generally has no unpleasant odour or appearance, and is perfectly compatible with topical administration.
  • composition is intended for topical administration, that is to say for administration by application at the surface of the keratin material under consideration, such a medium is considered in particular to be physiologically acceptable when it does not cause stinging, tightness or redness unacceptable to the user.
  • human keratin materials is intended to mean the skin (of the body, face and eye contour area), hair, eyelashes, eyebrows, body hair, nails, lips or mucous membranes.
  • anhydrous composition is intended to mean a composition containing less than 2% by weight of water, or even less than 0.5% of water, and in particular free of water, the water not being added during the preparation of the composition but corresponding to the residual water provided by the mixed ingredients.
  • the composition according to the invention has a viscosity from 0.0001 to 0.55 Pa.s, preferably from 0.001 to 0.5 Pa.s and more preferably from 0.03 to 0.4 Pa.s, measured at 25°C on a Haake RS600 rheometer, with sandblasted cone-plate geometry, diameter 60 mm, 2° and an imposed rate gradient sweep of from 1 to 500 s "1 (preferably to 100 s "1 ), at equilibrium.
  • Liposoluble organic UV-screening agent is intended to mean any organic or inorganic compound for screening out UV radiation with a wavelength between 280 nm and 400 nm capable of being fully dissolved in molecular form or miscible in a liquid fatty phase or else of being dissolved in colloidal form (for example in micellar form) in an oily phase.
