Description

La présente invention concerne le domaine général des films utilisés au contact de la peau en vue d'exercer sur celle-ci une action cosmétique et/ou curative.The present invention relates to the general field of films used in contact with the skin in order to exert on it cosmetic and / or curative action.

On connaít déjà des films qui sont appliqués temporairement sur la peau pour en extraire les impuretés et/ou libérer une substance active par transdermie, de tels films étant encore appelés "patch".We already know films that are temporarily applied on the skin to extract impurities and / or release a substance active by transdermia, such films also being called "patch".

L'utilisation de ces films est rendue difficile par le fait que l'on ne dispose pas toujours de la forme adaptée à la région du visage ou du corps à traiter.The use of these films is made difficult by the fact that we do not always have the shape adapted to the region of face or body to be treated.

En outre, ces films présentent une structure multicouche et sont relativement épais, donc peu confortables sur la peau.In addition, these films have a multilayer structure and are relatively thick and therefore not very comfortable on the skin.

De surcroít, leur aspect et leur épaisseur ne permettent pas à l'utilisateur de les porter de façon discrète.In addition, their appearance and thickness do not allow the user to wear them discreetly.

On connaít par ailleurs des compositions qui se transforment en films pelables en séchant, encore appelées compositions filmogènes, conditionnées en pot ou en tube et que l'on applique au doigt ou à la spatule de manière relativement grossière sur le visage pour former un masque.We also know compositions that are transformed in peelable films when drying, also called film-forming compositions, packaged in a jar or tube and applied by finger or relatively coarse spatula on the face to form a mask.

L'application irrégulière de ces compositions filmogènes laisse des traces visibles qui ne permettent pas non plus à l'utilisateur de sortir ou de travailler sans que son entourage ne le remarque.Irregular application of these film-forming compositions leaves visible traces which also do not allow the user to go out or work without those around him Note.

Il existe donc un besoin pour disposer d'un film facile à mettre en place quelle que soit la région du visage ou du corps à traiter, qui soit confortable et qui puisse également être porté avec discrétion si nécessaire.There is therefore a need to have a film that is easy to put in place whatever face or body region to treat, which is comfortable and which can also be worn with discretion if necessary.

L'invention y parvient grâce à un dispositif permettant l'application d'une composition filmogène sur la peau, caractérisé par le fait qu'il comporte :

  • un récipient contenant ladite composition filmogène,
  • un applicateur comportant un élément d'application,
  • un organe d'essorage à l'intérieur du récipient,
l'élément d'application et l'organe d'essorage étant agencés de manière à ce que l'élément d'application, après essorage, laisse lorsque déplacé au contact de la peau un film de composition filmogène qui après séchage devient pelable et présente par unité de surface une masse comprise de préférence entre 1 et 15 mg/cm2.The invention achieves this by means of a device allowing the application of a film-forming composition to the skin, characterized in that it comprises:
  • a container containing said film-forming composition,
  • an applicator comprising an application element,
  • a wiper member inside the container,
the application element and the wiping member being arranged so that the application element, after wringing, leaves when moved in contact with the skin a film of film-forming composition which after drying becomes peelable and presents per unit area a mass preferably between 1 and 15 mg / cm2.

Grâce à l'invention, l'utilisateur peut aisément déposer sur la peau une épaisseur sensiblement constante de composition filmogène.Thanks to the invention, the user can easily deposit on the skin has a substantially constant thickness of film-forming composition.

Le film est facilement réalisé in situ par l'utilisateur à la taille qu'il souhaite.The film is easily produced in situ by the user at the size he wants.

ce film est confortable car souple et peu épais, et en outre il peut être rendu difficilement visible par l'entourage de l'utilisateur en étant au besoin recouvert par un produit de maquillage.this film is comfortable because it is flexible and not very thick, and furthermore it can be made difficult to see by those around the user being covered if necessary by a product of makeup.

La composition filmogène comporte de préférence au moins une substance active destinée au traitement pharmaceutique et/ou cosmétique de la peau.The film-forming composition preferably comprises at least one active substance intended for pharmaceutical treatment and / or cosmetic of the skin.

De préférence, l'élément d'application est à capillarité externe, c'est-à-dire que la composition filmogène ne se dépose qu'à sa surface.Preferably, the application element is capillary external, i.e. the film-forming composition is only deposited its surface.

De préférence, il s'agit d'un élément d'application comportant à sa surface un revêtement constitué de poils fins et souples avantageusement déposés par un procédé électrostatique sur un support non poreux.Preferably, it is an application element comprising on its surface a coating made up of fine and flexible hairs advantageously deposited by an electrostatic process on a support non-porous.

De préférence, la longueur des poils est comprise entre 0,2 et 1,5 mm et l'organe d'essorage est constitué par un bloc de mousse.Preferably, the length of the bristles is between 0.2 and 1.5 mm and the wiper member consists of a block of foam.

L'élément d'application, lorsqu'il est à capillarité externe, n'absorbe pas de produit en profondeur, de sorte que lorsqu'il est pressé sur la peau il n'est pas susceptible de réabsorber substantiellement le produit précédemment déposé sur celle-ci. Au contraire lorsque l'élément d'application est constitué par une mousse à cellules ouvertes, alors celle-ci peut réabsorber dans une certaine mesure le produit déjà déposé sur la peau.The application element, when it is externally capillary, does not absorb product deeply, so that when it is pressed on the skin it is not likely to reabsorb substantially the product previously deposited thereon. At contrary when the application element is constituted by a foam with open cells, then this can reabsorb in a certain measures the product already deposited on the skin.

L'invention a encore pour objet un procédé pour former in situ et au format souhaité à la surface de la peau un film pelable, caractérisé par le fait qu'il comporte les étapes consistant à :

  • appliquer sur la peau au moyen d'un élément d'application, de préférence à capillarité externe, une couche d'épaisseur sensiblement constante d'une composition filmogène provenant d'un récipient muni d'un organe d'essorage, l'élément d'application et l'organe d'essorage étant choisis de telle sorte que l'élément d'application laisse à la surface de la peau un film pelable présentant une masse par unité de surface comprise entre 1 et 15 mg/cm2, la composition filmogène comprenant de préférence au moins une substance active destinée au traitement pharmaceutique et/ou cosmétique de la peau,
  • laisser sécher la composition filmogène déposée sur la peau par l'élément d'application.
The invention also relates to a process for forming in situ and in the desired format on the surface of the skin a peelable film, characterized in that it comprises the steps consisting in:
  • applying to the skin by means of an application element, preferably with external capillarity, a layer of substantially constant thickness of a film-forming composition originating from a container fitted with a wiping member, the element d application and the wiping member being chosen such that the application element leaves a peelable film on the surface of the skin having a mass per unit area of between 1 and 15 mg / cm 2, the film-forming composition preferably comprising at least one active substance intended for pharmaceutical and / or cosmetic treatment of the skin,
  • allow the film-forming composition deposited on the skin by the application element to dry.

L'invention a encore pour objet un procédé de traitement cosmétique, caractérisé par le fait qu'il comprend les étapes consistant à :

  • appliquer sur la peau au moyen d'un élément d'application, de préférence à capillarité externe, une couche d'épaisseur sensiblement constante d'une composition filmogène provenant d'un récipient muni d'un organe d'essorage, l'élément d'application et l'organe d'essorage étant choisis de telle sorte que l'élément d'application laisse à la surface de la peau un film pelable présentant une masse par unité de surface comprise entre 1 et 15 mg/cm2, la composition filmogène comportant en outre une ou plusieurs substances actives ayant une action cosmétique sur la peau,
  • laisser en place la composition filmogène déposée sur la peau par l'élément d'application pendant la durée utile du traitement,
  • enlever le film.
The subject of the invention is also a cosmetic treatment method, characterized in that it comprises the steps consisting in:
  • applying to the skin by means of an application element, preferably with external capillarity, a layer of substantially constant thickness of a film-forming composition originating from a container fitted with a wiping member, the element d application and the wiping member being chosen such that the application element leaves a peelable film on the surface of the skin having a mass per unit area of between 1 and 15 mg / cm 2, the film-forming composition further comprising one or more active substances having a cosmetic action on the skin,
  • leave in place the film-forming composition deposited on the skin by the application element for the useful duration of the treatment,
  • remove the film.

L'invention a encore pour objet l'utilisation d'au moins une substance active ayant un effet curatif sur la peau dans la fabrication d'une composition filmogène destinée à être appliquée sur la peau pour former un film pelable, cette composition filmogène constituant après séchage à la surface de la peau un film présentant une masse par unité de surface comprise entre 1 et 15 mg/cm2.Another subject of the invention is the use of at least one active substance having a curative effect on the skin in the manufacture of a film-forming composition intended to be applied to the skin to form a peelable film, this film-forming composition constituting after drying on the surface of the skin a film having a mass per unit area of between 1 and 15 mg / cm2.

L'invention a encore pour objet un patch comportant une composition filmogène ayant polymérisé et au moins une substance active destinée au traitement cosmétique et/ou pharmaceutique de la peau, présentant une épaisseur sensiblement constante et une masse par unité de surface comprise en 1 et 15 mg/cm2. The invention also relates to a patch comprising a film-forming composition having polymerized and at least one substance active for cosmetic and / or pharmaceutical treatment of skin, having a substantially constant thickness and a mass per surface area between 1 and 15 mg / cm2.

D'autres caractéristiques et avantages de la présente invention ressortiront à la lecture de la description détaillée qui va suivre, d'un exemple de réalisation non limitatif de l'invention, et à l'examen du dessin annexé sur lequel :

  • la figure 1 est une vue schématique en coupe d'un dispositif conforme à l'invention, permettant l'application d'une composition filmogène sur la peau,
  • la figure 2 illustre l'application de la composition filmogène sur la peau au moyen de l'applicateur du dispositif de la figure 1.
Other characteristics and advantages of the present invention will emerge on reading the detailed description which follows, of a non-limiting exemplary embodiment of the invention, and on examining the appended drawing in which:
  • FIG. 1 is a schematic sectional view of a device according to the invention, allowing the application of a film-forming composition to the skin,
  • FIG. 2 illustrates the application of the film-forming composition to the skin by means of the applicator of the device in FIG. 1.

Le dispositif de conditionnement et d'application 1 représenté sur la figure 1 présente un faible encombrement lui permettant d'être facilement transporté dans une poche ou un sac. Il comporte un récipient 2 formant réservoir et un applicateur 3 comportant une tige 4, avantageusement flexible, munie à une extrémité d'un élément d'application 5 et à l'autre extrémité d'un organe de préhension 6.The packaging and application device 1 shown in Figure 1 has a small footprint allowing it to be easily carried in a pocket or bag. It has a container 2 forming a reservoir and an applicator 3 comprising a rod 4, advantageously flexible, provided at one end with an element 5 and at the other end of a gripping member 6.

Le récipient 2 est formé par l'assemblage d'un corps 8 ouvert en partie supérieure et d'une pièce d'extrémité épaulée 9 sur laquelle est réalisé le col 7 du récipient.The container 2 is formed by the assembly of an open body 8 in the upper part and a shoulder end piece 9 on which the neck 7 of the container is made.

Un organe d'essorage 11, constitué d'un bloc de mousse à cellules ouvertes, pourvu en son centre d'un évidement axial pour le passage de la tige 4 et de l'élément d'application 5 de l'applicateur 3 est fixé sur la face intérieure de la pièce d'étanchéité 9. L'organe d'essorage 11 est fixé par soudage par exemple. Un jeu annulaire 10 est ménagé entre la surface radialement extérieure de l'organe d'essorage 11 et la surface radialement intérieure du corps 8, de manière à permettre une expansion radiale de la mousse lorsqu'elle est traversée par l'élément d'application.A wiper member 11, consisting of a block of foam open cells, provided in its center with an axial recess for the passage of the rod 4 and of the application element 5 of the applicator 3 is fixed on the inside of the part sealing 9. The wiper member 11 is fixed by welding by example. An annular clearance 10 is formed between the surface radially outside of the wiper member 11 and the surface radially inside the body 8, so as to allow a radial expansion of the foam when the application element passes through it.

L'organe de préhension 6 comporte un filetage intérieur 12 qui vient en prise sur un filetage extérieur du col 7 pour assurer la fermeture étanche du récipient 2, la tige 4 traversant alors l'organe d'essorage 11 et l'élément d'application 5 se situant à proximité du fond du corps 8.The gripping member 6 has an internal thread 12 which engages on an external thread of the neck 7 to ensure the tight closure of the container 2, the rod 4 then passing through the member wringing 11 and the application element 5 located near the body bottom 8.

Le col 7 n'est pas fileté à son extrémité supérieure, de manière à éviter, en cas de formation d'un dépôt sur le col 7, que ce dépôt ne gêne le vissage ultérieur de l'élément de préhension 6. The neck 7 is not threaded at its upper end, so as to avoid, if a deposit is formed on the neck 7, that this deposit does not interfere with the subsequent screwing of the gripping element 6.

Le récipient 2 est rempli d'une composition filmogène incolore F, comportant un ou plusieurs polymères et un ou plusieurs solvants.The container 2 is filled with a film-forming composition colorless F, comprising one or more polymers and one or more solvents.

Comme polymères utilisables, on peut citer l'alcool polyvinylique, un latex soluble, l'EVA, le polyuréthane ou une résine acrylique, et comme solvants on peut citer par exemple l'eau ou l'alcool, le ou les solvants étant choisis en fonction du ou des polymères utilisés.As polymers which can be used, mention may be made of alcohol polyvinyl, soluble latex, EVA, polyurethane or resin acrylic, and as solvents there may be mentioned for example water or alcohol, the solvent (s) being chosen according to the polymers used.

Dans l'exemple de réalisation décrit, l'élément d'application 5 présente une forme allongée, symétrique de révolution.In the example of embodiment described, the element Application 5 has an elongated shape, symmetrical in revolution.

Il est constitué d'un support non poreux rapporté sur la tige 4 ou venu de formation avec elle, recouvert de poils fins et souples, en nylon par exemple, dont la longueur est comprise entre 0,2 et 1,5 mm, de préférence de l'ordre de 1mm, ces poils ayant été déposés par voie électrostatique sur ledit support.It consists of a non-porous support attached to the rod 4 or come from formation with it, covered with fine hairs and flexible, in nylon for example, the length of which is between 0.2 and 1.5 mm, preferably of the order of 1 mm, these hairs having been deposited electrostatically on said support.

Pour utiliser le dispositif 1, l'utilisateur dévisse l'organe de préhension 6 et extrait l'élément d'application 5 de l'intérieur du récipient 2 au travers de l'organe d'essorage 11.To use the device 1, the user unscrews the organ grip 6 and extracts the applicator element 5 from inside the container 2 through the wiper member 11.

L'élément d'application 5 et l'organe d'essorage 11 sont agencés de telle sorte qu'il subsiste à la surface de l'élément d'application 5, après son extraction du récipient 2, une faible épaisseur de composition filmogène F, non polymérisée, laquelle peut être appliquée au format souhaité par l'utilisateur sur la peau au niveau de la région du visage ou du corps à traiter, comme illustré sur la figure 2.The applicator element 5 and the wiper member 11 are arranged so that it remains on the surface of the element application 5, after its extraction from the container 2, a low thickness of film-forming composition F, not polymerized, which can be applied in the format desired by the user on the skin at level of the area of the face or body to be treated, as illustrated in figure 2.

L'épaisseur de produit laissée sur la peau est fonction de la longueur des poils de l'élément d'application 5.The thickness of product left on the skin depends on the length of the hairs of the applicator element 5.

Dans l'exemple décrit, la composition filmogène F polymérise au fur et à mesure de l'évaporation du ou des solvants qu'elle contient.In the example described, the film-forming composition F polymerizes as the solvent (s) evaporates contains.

On comprend que, grâce à l'invention, il est aisé pour l'utilisateur de réaliser un film dont la taille correspond exactement à la zone à traiter.We understand that, thanks to the invention, it is easy to the user to make a film whose size exactly matches to the area to be treated.

Il peut s'agir de recouvrir un bouton ou un point noir par exemple. It can be to cover a button or a black dot by example.

Il convient en outre de remarquer que la flexibilité de la tige 4 dans l'exemple décrit permet une application en douceur, donc sans irriter la zone traitée.It should also be noted that the flexibility of the rod 4 in the example described allows a smooth application, therefore without irritating the treated area.

Une fois que la composition filmogène est polymérisée, c'est-à-dire que le film est sec l'utilisateur peut, le cas échéant, le recouvrir d'un produit de maquillage pour le rendre pratiquement indécelable.Once the film-forming composition is polymerized, that is to say that the film is dry the user can, if necessary, cover it with a makeup product to make it practically undetectable.

Le film est retiré en le décollant de la peau, ou dans le cas où le ou les polymères utilisés sont des polymères hydrosolubles dont le solvant est aqueux et dont la polymérisation est réversible, par lavage à l'eau.The film is removed by peeling it from the skin, or in the case where the polymer or polymers used are water-soluble polymers of which the solvent is aqueous and the polymerization of which is reversible, by wash with water.

Lorsqu'il est retiré, le film peut désincruster les impuretés.When removed, the film can scale out impurities.

D'une manière générale, la composition filmogène F déposée sur la peau constitue, après séchage, un film qui présente par unité de surface une masse comprise entre 1 et 15 mg/cm2, et de préférence entre 1 et 10 mg/cm2 et de préférence entre 1,5 et 5 mg/cm2.In general, the film-forming composition F deposited on the skin constitutes, after drying, a film which has per unit of surface a mass between 1 and 15 mg / cm2, and preferably between 1 and 10 mg / cm2 and preferably between 1.5 and 5 mg / cm2.

Le temps de séchage de la composition filmogène F sur la peau est compris entre 1 et 5 minutes, de préférence entre 2 et 4 minutes.The drying time of the film-forming composition F on the skin is between 1 and 5 minutes, preferably between 2 and 4 minutes.

La composition filmogène F peut comporter une ou plusieurs substances actives connues ayant un effet cosmétique ou curatif sur la peau, tels que des tanins, cires,anti-tâches, anti-rides, anti-oxydants, anti-radicaux libres, hydratants, dépigmentants, liporégulateurs, amincissants, anti-acnéiques, anti-psoriatiques, anti-séborrhéiques, antihistaminiques, anti-vieillissement, anti-inflammatoires, rafraíchissants, protecteurs vasculaires, anti-bactériens, anti-fongiques, anti-perspirants, conditionneurs de la peau, immunomodulateurs, agents nourrissants et insensibilisants.The film-forming composition F can comprise one or more known active substances having a cosmetic or curative effect on the skin, such as tannins, waxes, anti-stains, anti-wrinkles, antioxidants, anti-free radicals, hydrating, depigmenting, liporegulators, slimming, anti-acne, anti-psoriatic, anti-seborrhoeic, antihistamine, anti-aging, anti-inflammatory, refreshing, vascular protectors, anti-bacterial, anti-fungal, anti-perspirants, conditioners the skin, immunomodulators, nourishing and insensitizing agents.

Le film de composition filmogène déposé sur la peau tend à sécher plus rapidement en surface qu'au contact de la peau.The film of film-forming composition deposited on the skin tends to dry faster on the surface than in contact with the skin.

La composition filmogène F peut ainsi rester au contact de la peau sans polymériser immédiatement pour permettre aux substances actives contenues à l'intérieur de diffuser dans la peau.The film-forming composition F can thus remain in contact with the skin without immediately curing to allow substances active ingredients inside diffuse into the skin.

L'évaporation des substances actives, lorsque celles-ci sont volatiles, est en outre ralentie dans une certaine mesure par le fait que le film commence par sécher en surface.Evaporation of the active substances, when these are volatile, is further slowed to some extent by the fact let the film dry on the surface first.

A titre d'exemple, on a réalisé une composition filmogène F ayant la formulation suivante (% en masse) :

  • 75 % d'eau,
  • 5 % d'éthanol,
  • 5 % d'une substance active hydrosoluble telle que la caféine,
  • 10% de polymère pseudo latex polyuréthane,
  • 5 % d'un conservateur.
By way of example, a film-forming composition F was produced having the following formulation (% by mass):
  • 75% water,
  • 5% ethanol,
  • 5% of a water-soluble active substance such as caffeine,
  • 10% of pseudo-latex polyurethane polymer,
  • 5% of a preservative.

Cette composition est destinée à être appliquée sur le visage pour traiter les poches sous les yeux.This composition is intended to be applied to the face to treat bags under the eyes.

On a réalisé une autre composition filmogène ayant la formulation suivante (% en masse) :

  • 70% d'eau,
  • 15% d'alcool polyvinylique
  • 10% d'une substance active hydrosoluble telle qu'un extrait végétal,
  • 5% de substances actives liposolubles tel que de l'acide salicylique.

Cette composition est destinée à être appliquée sur des zones d'érythème et peut être gardée une journée.This composition is intended to be applied to areas erythema and can be kept for a day.

Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation qui vient d'être décrit.Of course, the invention is not limited to the example of realization which has just been described.

On peut notamment utiliser des applicateurs différents de celui qui est représenté sur les figures, par exemple des applicateurs dont la tige est coudée, ou dont l'élément d'application présente une forme particulière, non symétrique de révolution, adaptée au traitement d'une région spécifique du visage.One can in particular use applicators different from the one shown in the figures, for example applicators the stem of which is bent, or the application element of which has a particular shape, not symmetrical in revolution, suitable for treatment of a specific region of the face.

L'applicateur peut comporter une ou plusieurs fentes et/ou alvéoles retenant le produit par capillarité.The applicator may have one or more slots and / or alveoli retaining the product by capillary action.
