  • This gel has several disadvantages. It is too sticky to be removed easily and the film obtained after drying is not cohesive enough to be peeled off in one piece so that it leaves many residues on the eyelid. It must therefore be removed with a cleansing lotion by performing several wipes that can be irritating to the eyelid whose skin is particularly fragile. Finally, at such a high solids content, the copolymer can pose toxicity problems.

Abstract

The present invention concerns an adhesive product for applying decoration or makeup accessories to the body, such as false eyelashes, for example. It concerns a glue comprising a combination of three polymers in dispersion: a styrene/acrylates copolymer, an acrylates/ethylhexyl acrylate copolymer and a polyvinyl alcohol. This glue allows the formation of a cohesive film that is not sticky to the touch and adhesive. A method for applying decoration accessories using this glue, and a kit allowing it to be implemented, are also proposed.

Description

Colle pour la pose d'accessoires de maquillage  Glue for applying makeup accessories
La présente invention concerne un produit adhésif destiné à la pose d'accessoires de maquillage sur le corps, notamment des faux cils. The present invention relates to an adhesive product for the installation of makeup accessories on the body, including false eyelashes.
ART ANTERIEUR PRIOR ART
Les premières colles utilisées pour fixer des petite accessoires de décoration sur le corps étaient à base de latex naturels. C'est le cas notamment de la colle décrite dans la demande WO 2012/087510.  The first glues used to fix small decorative accessories on the body were based on natural latex. This is particularly the case of the adhesive described in the application WO 2012/087510.
Ces colles présentent l'inconvénient de former un film de colle visible sur les paupières une fois sec et faiblement adhésif, si bien qu'il se décolle rapidement après la pose des faux cils. Par ailleurs, le film de colle est faiblement résistant à l'eau et sa rigidité crée des sensations de tiraillement inconfortables au cours de la journée.  These glues have the disadvantage of forming a film of glue visible on the eyelids once dry and weakly adhesive, so that it comes off quickly after the installation of false eyelashes. In addition, the glue film is weakly water resistant and its rigidity creates uncomfortable tightness during the day.
La recherche s'est donc tournée vers les copolymères acrylates en dispersion aqueuse, en particulier les copolymères éthylhexylacrylate/acrylates adhésifs. On trouve ainsi de nombreuses colles comprenant des copolymères de ce type. Elles en contiennent en très hautes proportion pour garantir un pouvoir adhésif suffisant : les teneurs usuelles sont de l'ordre de 40% voire 45% en masse de matière sèche.  The research therefore turned to acrylate copolymers in aqueous dispersion, in particular ethylhexylacrylate / adhesive acrylate copolymers. There are thus many glues comprising copolymers of this type. They contain very high levels to ensure sufficient adhesive power: the usual contents are of the order of 40% or 45% by weight of dry matter.
La demande US 2017/0027844 propose par exemple un gel aqueux adhésif comprenant un éthylhexylacrylate/acrylates à hauteur de 25% en masse d'extrait sec environ. Ce gel présente cependant plusieurs inconvénients. Il est trop collant pour être retiré facilement et le film obtenu après séchage n'est pas assez cohésif pour être décollé en une seule pièce si bien qu'il laisse de nombreux résidus sur la paupière. Il doit donc être retiré avec une lotion démaquillante en réalisant plusieurs essuyages qui peuvent être irritants pour la paupière dont la peau est particulièrement fragile. Enfin, à une teneur en matière sèche aussi élevée, le copolymère peut poser des problèmes de toxicité.  The application US 2017/0027844 proposes for example an aqueous adhesive gel comprising an ethylhexylacrylate / acrylates at a level of 25% by mass of solids approximately. This gel, however, has several disadvantages. It is too sticky to be removed easily and the film obtained after drying is not cohesive enough to be peeled off in one piece so that it leaves many residues on the eyelid. It must therefore be removed with a cleansing lotion by performing several wipes that can be irritating to the eyelid whose skin is particularly fragile. Finally, at such a high solids content, the copolymer can pose toxicity problems.
Le besoin subsiste donc de disposer d'une colle cosmétique qui permet de faire adhérer fortement un élément de décor à la peau, et de le retirer ensuite par décollement mécanique en un seul geste sans laisser de résidus de colle sur la peau et sans provoquer des sensations douloureuses chez l'utilisateur aussi bien pendant la journée après la pose, que lors du décollement.  The need therefore remains to have a cosmetic glue which makes it possible to strongly adhere a decorative element to the skin, and then to remove it by mechanical detachment in a single movement without leaving glue residues on the skin and without causing any damage. Painful sensations in the user as well during the day after the pose, as during the detachment.

On entend par « composition sous la forme d'un gel aqueux », une composition contenant une forte proportion d'eau, et dont la consistance se rapproche de celle d'un gel au sens sensoriel du terme.  The composition is preferably in the form of an aqueous paste or gel. The term "composition in the form of an aqueous gel", a composition containing a high proportion of water, and whose consistency is similar to that of a gel in the sensory sense of the term.
Par ailleurs, la demande décrit une composition adhésive sous la forme d'une dispersion aqueuse comprenant la combinaison de trois polymères adhésifs dont un premier copolymère obtenu à partir du monomère éthylhexyl(méth)acrylate et d'au moins un autre monomère (méth)acrylate, et un deuxième copolymère obtenu à partir du monomère styrène et d'au moins un autre monomère (méth)acrylate, et un alcool polyvinylique, dans laquelle le premier copolymère représente entre 1% et 20% en masse, de préférence entre 2% et 10% en masse de la masse de la composition.

Le mélange de monomère peut également comprendre du styrène, et de l'acide (méth)acrylique. The application also discloses an aqueous adhesive gel comprising the combination of three polymers including i) a first copolymer obtained from a monomer mixture comprising an ethylhexyl (meth) acrylate monomer, and at least one other (meth) alkylate monomer.

This architecture may comprise at least one of the following characteristics: the water represents between 50 and 70% by weight of the mass of the composition; the first copolymer represents between 1% and 20% by weight, preferably between 2% and 10% by weight of the mass of the composition; the second copolymer represents between 5% and 25% by weight, preferably between 15% and 20% by weight of the mass of the composition; the ratio between the first copolymer and the second copolymer is between 0.1 and 0.8, preferably between 0.1 and 0.5; the first copolymer and the second copolymer are in the form of an aqueous dispersion in the composition; the second copolymer is chosen from copolymers obtained from a mixture comprising at least two monomers chosen from C1-C8 alkyl (meth) acrylate, for example methyl (meth) acrylate, ethyl (meth) acrylate, butyl (meth) acrylate or nsobutyl (meth) acrylate, ethylhexylacrylate. The monomer mixture may also include styrene, and (meth) acrylic acid.
Les caractéristiques et propriétés qui seront décrites ci-après s'appliquent aux trois types de composition qui viennent d'être présentées.  The characteristics and properties that will be described below apply to the three types of composition that have just been presented.
Le deuxième copolymère représente de préférence entre 1% et 25% en masse de la masse de la composition, le pourcentage étant exprimé en poids sec. La teneur en deuxième composition est de préférence inférieure à 25%, 20%, 15%, 10% ou 8%, et de préférence supérieure à 1%, 2%, 3% ou 4% en masse, de la masse de la composition, le pourcentage étant exprimé en poids sec.  The second copolymer preferably represents between 1% and 25% by weight of the mass of the composition, the percentage being expressed in dry weight. The content of the second composition is preferably less than 25%, 20%, 15%, 10% or 8%, and preferably greater than 1%, 2%, 3% or 4% by weight, of the mass of the composition. the percentage being expressed in dry weight.
L'adhésif de l'invention présente l'originalité de concilier une forte adhérence à la peau prolongeant ainsi la tenue des accessoires de maquillage dans le temps, et un décollement plus facile après leur utilisation, sans provoquer de nnconfort chez l'utilisateur. L'adhésif a également l'avantage de former un film très cohésif, transparent, inodore, non collant et souple à la fois après séchage de l'eau qu'il contient. Le temps de séchage du produit sur les paupières peut être très court, et sa consistance permet d'optimiser la quantité de produit déposée. The adhesive of the invention has the originality of reconciling a strong adhesion to the skin thus prolonging the resistance of makeup accessories over time, and easier peeling after use, without causing discomfort to the user. The adhesive also has the advantage of forming a very cohesive film, transparent, odorless, non-sticky and flexible both after drying of the water it contains. The drying time of the product on the eyelids can be very short, and its consistency can optimize the amount of product deposited.
L'absence de sensation de collant et la souplesse du film laissé sur la peau après séchage procure un grand confort à l'utilisateur. Au surplus, les accessoires de maquillage comme les faux-cils qui ont été collés sur la peau peuvent être retirés par simple décollement mécanique, sans avoir recours à un essuyage répété à l'aide de lotions démaquillantes qui s'avèrent nécessaires dans l'art antérieur. Ceci est d'autant plus appréciable que les compositions cosmétiques utilisées pour le maquillage de la peau comprenant de grandes proportions de polymères laissent généralement de grandes quantités de résidus qui adhèrent fortement à la peau.  The absence of stickiness and flexibility of the film left on the skin after drying provides great comfort to the user. In addition, makeup accessories such as false eyelashes that have been stuck to the skin can be removed simply by mechanical detachment, without resorting to repeated wiping with makeup remover lotions that are necessary in the art prior. This is all the more appreciable since cosmetic compositions used for the make-up of the skin comprising large proportions of polymers generally leave large quantities of residues which adhere strongly to the skin.
L'adhésif présente une très bonne tenue à l'eau, par exemple l'eau de baignade, la transpiration ou les larmes. Il peut être décollé après avoir appliqué par pression un coton imbibé d'une huile. The adhesive has a very good resistance to water, for example bathing water, perspiration or tears. It can be peeled off after you apply by pressure a cotton soaked with an oil.
La composition adhésive de l'invention peut présenter l'avantage d'être transparente une fois sèche. Elle est donc de préférence dépourvue de pigments tels que le noir de carbone, qui part ailleurs peuvent générer des problèmes de stabilité et nécessiter l'usage de composés additionnels pour les disperser dans la composition, composés additionnels qui risqueraient également de compromettre les propriétés avantageuses du film sec de la composition adhésive de l'invention.  The adhesive composition of the invention may have the advantage of being transparent once dry. It is therefore preferably devoid of pigments such as carbon black, which elsewhere can cause stability problems and require the use of additional compounds to disperse them in the composition, additional compounds which would also risk compromising the advantageous properties of the product. dry film of the adhesive composition of the invention.
Les performances de stabilité de la composition adhésive de l'invention au cours du temps, et les propriétés mécaniques des films obtenus après étalement et séchage de cette composition sont d'autant plus inattendues que les problèmes de stabilité rencontrés dans le domaine de la formulation cosmétique sont accrus en présence d'un grand nombre d'ingrédients, et de fortes proportions de polymères. The stability performance of the adhesive composition of the invention over time, and the mechanical properties of the films obtained after spreading and drying of this composition are all the more unexpected as the stability problems encountered in the field of cosmetic formulation are increased in the presence of a large number of ingredients, and high proportions of polymers.

Selon un mode de réalisation, le premier copolymère est obtenu à partir d'éthylhexylacrylate et d'un mélange de plusieurs monomères (méth)acrylates, par exemple le mélange de butyl acrylate et de méthyl méthacrylate, ou le mélange d'éthyl acrylate et de méthyl méthacrylate. The first copolymer is, for example, obtained from a mixture of from 30% to 70%, preferably from 40% to 60%, of ethylhexylacrylate, and from 30% to 70%, preferably from 40% to 60%, of the said at least one monomer (meth) acrylate.

In one embodiment, the second copolymer is obtained by a monomer mixture free of a (meth) acrylic acid monomer. The second copolymer can be obtained from a monomer mixture comprising exclusively C1-C8 alkyl (meth) acrylate monomers, preferably C1 to C6.
Les particules du deuxième copolymère représentent par exemple entre 5% et 25% en masse, de préférence encore entre 15% et 20% en masse de la masse de la composition, et peuvent avoir une taille comprise entre 100 et 200 nanomètres.

Les caractéristiques énoncées précédemment à l'égard du copolymère styrène/acrylates peuvent s'appliquer le cas échéant au copolymère acrylates. Selon un mode de réalisation, le ratio massique entre le premier copolymère et le deuxième copolymère est compris entre 0.05 et 2.0, de préférence entre 0.1 et 1.0, de préférence entre 0.1 et 0.8, de préférence encore entre 0.1 et 0.5. Alternatively, it is possible to use as the second copolymer an acrylate copolymer which is not derived from the copolymerization of styrene, and which has a glass transition temperature of between -10 ° C. and 60 ° C., preferably between -5 ° C. and 40 ° C, and more preferably between 0 ° C and 30 ° C. The acrylate copolymer can be obtained from at least two alkyl (meth) acrylate monomers which are preferably chosen from (C 1 to C 8) alkyl (meth) acrylates, for example a butyl acrylate monomer, the ethylhexyl acrylate, ethyl acrylate, methyl methacrylate or methyl acrylate. The characteristics stated above with respect to the styrene / acrylate copolymer can be applied, if appropriate, to the acrylate copolymer. According to one embodiment, the mass ratio between the first copolymer and the second copolymer is between 0.05 and 2.0, preferably between 0.1 and 1.0, preferably between 0.1 and 0.8, more preferably between 0.1 and 0.5.
Le premier copolymère et le deuxième copolymère peuvent comprendre des fonctions carboxyliques ou carboxylates. Dans un mode de réalisation, ni le premier ni le deuxième copolymère n'en comprennent simultanément, ou, dans un autre mode de réalisation, le premier et le deuxième copolymère en comprennent simultanément. Il est avantageux qu'une dispersion comprenant des particules du premier copolymère et des particules du deuxième copolymère ne comprenne pas de tension actif ionique ou non ionique parfois nécessaire pour les stabiliser. The first copolymer and the second copolymer may comprise carboxylic or carboxylate functions. In one embodiment, neither the first nor the second copolymer includes them simultaneously, or, in another embodiment, the first and second copolymers simultaneously. include simultaneously. It is advantageous for a dispersion comprising particles of the first copolymer and particles of the second copolymer to comprise no ionic or nonionic active voltage sometimes necessary to stabilize them.
La viscosité de la dispersion du premier copolymère et la viscosité de la dispersion du deuxième copolymère que l'on peut utiliser pour préparer la composition de l'invention est de préférence mesurée à 25°C en prenant 200 ml de la dispersion à 55% d'extrait sec, avec un appareil VISCOMETER TVB-10M (TOKI SANGYO∞., LTD.) en prenant l'aiguille M2 (cord No. 21) tournant à la vitesse de 60 rpm.  The viscosity of the dispersion of the first copolymer and the viscosity of the dispersion of the second copolymer which can be used to prepare the composition of the invention is preferably measured at 25 ° C by taking 200 ml of the 55% dispersion. dry extract, with a VISCOMETER TVB-10M (TOKI SANGYO®, LTD.), taking the M2 needle (cord No. 21) rotating at a speed of 60 rpm.
La composition peut être constituée d'eau, du premier copolymère, du deuxième copolymère, de l'alcool polyvinylique, et de conservateurs.  The composition may consist of water, the first copolymer, the second copolymer, polyvinyl alcohol, and preservatives.
La composition peut éventuellement comprendre un troisième polymère choisi parmi les copolymères acrylates, qui permet encore d'améliorer la cohésion du film de composition une fois l'eau évaporée.  The composition may optionally comprise a third polymer chosen from acrylate copolymers, which makes it possible to improve the cohesion of the composition film once the water has evaporated.
L'alcool polyvinylique représente de préférence entre 5% et 15% en masse, de préférence entre 8% et 12% en masse de la masse de la composition. Les inventeurs ont pu constater de façon étonnante que l'utilisation d'hydroxyéthylcellulose ne permet pas d'obtenir un film de composition, une fois l'eau évaporée, qui soit cohésif et puisse être retiré facilement de la surface du corps sur laquelle il a été collé, en un seul morceau, sans laisser des résidus sur la peau. The polyvinyl alcohol is preferably between 5% and 15% by weight, preferably between 8% and 12% by weight of the mass of the composition. The inventors have surprisingly found that the use of hydroxyethylcellulose does not make it possible to obtain a film of composition, once the water has evaporated, which is cohesive and can be easily removed from the surface of the body on which it has stuck in one piece, leaving no residue on the skin.
L'alcool polyvinylique utilisé dans le cadre de l'invention remplit le rôle de gélifiant de l'eau, mais permet surtout d'obtenir un film de composition pelable sans devoir essuyer la colle séchée avec une lotion démaquillante. L'hydroxyéthylcellulose en permet pas d'obtenir ce résultat.  The polyvinyl alcohol used in the context of the invention fulfills the role of gelling of water, but above all makes it possible to obtain a film of peelable composition without having to wipe the dried glue with a cleansing lotion. Hydroxyethylcellulose can not achieve this result.
Dans un mode de mise en œuvre, l'alcool polyvinylique est obtenu par hydrolyse du polyacétate de vinyle et comprend à la fois des motifs alcool vinylique et acétate de vinyle. On préfère que l'alcool polyvinylique soit partiellement hydrolysé ; son taux d'hydrolyse mesuré par RMN C13 peut être notamment inférieure à 95%, de préférence compris entre 85% et 90%, de préférence encore entre 87 et 89%.

L'invention concerne également un procédé d'utilisation d'un accessoire de maquillage qui comprend les étapes consistant à The invention also relates to a method of using a makeup accessory which comprises the steps of
- fournir à un utilisateur un accessoire de maquillage tel que par exemple des faux cils,  providing a user with a makeup accessory such as, for example, false eyelashes,
- déposer sur l'accessoire de maquillage, à l'aide d'un applicateur, la composition adhésive conforme à ce qui vient d'être décrit, de manière à obtenir un accessoire de maquillage encollé sur une de ses surfaces par un film de composition, depositing on the makeup accessory, using an applicator, the adhesive composition as described above, so as to obtain a makeup accessory glued on one of its surfaces by a composition film,
- mettre en contact la surface de l'accessoire de maquillage encollé et la partie du corps de l'utilisateur que l'on souhaite décorer,  putting the surface of the glued makeup accessory into contact with the part of the body of the user that is to be decorated,
- appuyer légèrement sur l'accessoire jusqu'à séchage du film de composition, qui peut devenir transparent.  - lightly press the accessory until the composition film has dried, which may become transparent.
Ce procédé peut comprendre une étape de retrait de l'accessoire consécutive à l'étape de mise en contact, laquelle étape de retrait consiste à décoller l'accessoire de maquillage encollé en un seul geste.  This method may include a step of removing the accessory after the contacting step, which removal step is to take off the glue makeup accessory in a single gesture.
Le procédé peut comprendre une étape de retrait par décollement de l'accessoire enduit d'un film de la composition adhésive séchée ; le décollement étant réalisé en tirant sur l'accessoire. Le décollement de l'accessoire par traction présente l'avantage de retirer en un seul geste l'accessoire et la totalité du film de composition adhésive, sans qu'il reste des résidus de cette composition sur le corps, et sans douleur pour l'utilisateur. Le décollement mécanique peut être précédé d'une étape consistant à préparer un coton imprégné d'une lotion démaquillante et à placer le coton sur la partie de la peau recouverte de l'accessoire en appuyant légèrement pendant un instant sans essuyage.  The method may include a step of peel-off of the film-coated accessory from the dried adhesive composition; the detachment being achieved by pulling on the accessory. The detachment of the accessory by traction has the advantage of removing in a single gesture the accessory and the entire adhesive composition film, without residues of this composition remaining on the body, and without pain for the user. The mechanical detachment may be preceded by a step of preparing a cotton impregnated with a cleansing lotion and placing the cotton on the part of the skin covered with the accessory by pressing lightly for a moment without wiping.
L'invention concerne également un procédé d'utilisation de faux-cils qui comprend les étapes consistant à The invention also relates to a method of using false eyelashes which comprises the steps of
- fournir des faux cils à un utilisateur,  - provide false eyelashes to a user,
- déposer à l'aide d'un applicateur la composition adhésive décrite précédemment, sur la base des faux cils,  depositing with the aid of an applicator the adhesive composition described above, on the basis of false eyelashes,
- mettre en contact la base des faux cils et la base des cils et appuyer légèrement jusqu'à séchage de la composition.  putting the base of the false eyelashes in contact with the base of the eyelashes and lightly pressing until the composition is dried.
Les faux cils peuvent être sous la forme de franges ou des bottes. Les bottes de faux cils peuvent comprendre un ou plusieurs faux cils.  False eyelashes can be in the form of fringes or boots. The false eyelash boots may include one or more false eyelashes.
La mise en contact est réalisée de manière à faire adhérer les faux cils et la partie de la paupière située à la base des cils. Dans le cas d'une frange de faux cils complète, on pose la base de la frange en partant de préférence d'une des extrémités de la paupière pour terminer à l'autre extrémité. Le temps de séchage de la colle peut être inférieur à 1 minute, par exemple 30 secondes, voire même compris entre 10 et 20 secondes selon la quantité de produit appliquée.  The contacting is carried out so as to adhere the false eyelashes and the portion of the eyelid located at the base of the eyelashes. In the case of a complete fake eyelash fringe, the base of the fringe is placed starting preferably from one end of the eyelid to finish at the other end. The drying time of the adhesive may be less than 1 minute, for example 30 seconds, or even between 10 and 20 seconds depending on the amount of product applied.
Le procédé d'utilisation des faux-cils conforme à l'invention pourra comprendre une étape de retrait des faux-cils consécutive à l'étape de mise en contact, laquelle étape de retrait consiste à décoller la base des faux cils enduite de la composition adhésive séchée. Lorsque l'on retire des franges de faux cils complètes, on part de préférence de l'une des extrémités du faux-cils puis on tire progressivement à l'aide d'un moyen de préhension tel qu'une pince ou le doigt le long de la base des cils de manière à détacher complètement l'ensemble. The method of using the false eyelashes according to the invention may comprise a step of removing false eyelashes consecutive to the contacting step, which withdrawal step consists of taking off the false eyelashes coated base of the dried adhesive composition. When complete false eyelash fringes are removed, one preferably leaves one of the ends of the false eyelash and then is drawn gradually using a gripping means such as a clip or the finger along the base of the eyelashes so as to completely detach the whole.
Postérieurement à l'étape de retrait, les paupières peuvent éventuellement être essuyées à l'aide d'un support imprégné d'une lotion. Cette étape de nettoyage est cependant facultative dans le cadre de l'invention, car la colle est solidaire des faux cils et se décolle sous la forme d'un film pelable, souple et cohésif, qui laisse très peu voire aucun résidu sur la peau.  After the removal step, the eyelids may be wiped with a lotion impregnated support. This cleaning step is however optional in the context of the invention, because the glue is integral with the false eyelashes and comes off in the form of a peelable, flexible and cohesive film, which leaves very little or no residue on the skin.
Selon une variante de ce procédé, l'utilisateur retire les faux cils de leur emballage, vérifie l'ajustement dans le cas d'une frange complète, en alignant la frange du faux cil avec la ligne de ses cils pour vérifier si elle convient, coupe éventuellement les faux cils pour qu'ils s'adaptent à la forme des yeux à maquiller, applique une fine ligne de colle le long de la base des faux cils, attend pour que la colle prenne (en général 20 à 30 secondes suffisent), pose les faux cils le long de la ligne de base des cils naturels en partant de préférence d'une des extrémités dans le cas d'une frange complète, appuie délicatement sur les faux cils jusqu'à ce que la colle soit sèche. Pour améliorer le rendu du maquillage, l'utilisateur pourra s'il le juge nécessaire appliquer un trait d'eyeliner sur la paupière le long de la base des cils naturels. Les faux cils peuvent être appliqués au ras des cils naturels ou légèrement décalés par rapport à celle-ci. According to a variant of this method, the user removes the false eyelashes from their packaging, checks the adjustment in the case of a complete bangles, by aligning the false eyelash fringe with the line of his eyelashes to check if it is suitable, possibly cut the false eyelashes so that they adapt to the shape of the eyes to make up, apply a thin line of glue along the base of the false eyelashes, wait for the glue to take (in general 20 to 30 seconds are enough) placing the false eyelashes along the baseline of the natural eyelashes, preferably starting from one end in the case of a complete fringe, gently presses on the false eyelashes until the glue is dry. To improve the rendering of the makeup, the user can, if he deems it necessary, apply a line of eyeliner on the eyelid along the base of the natural eyelashes. The false eyelashes can be applied flush with natural eyelashes or slightly offset from it.
Une fois, les faux cils retirés, il est possible d'essuyer leur base avec un coton imprégné d'une lotion démaquillante à base d'huile, de manière à pouvoir les réutiliser.  Once the false eyelashes removed, it is possible to wipe their base with a cotton impregnated with an oil-based makeup remover lotion, so that they can be reused.

Le moyen d'application est par exemple un pinceau rendu solidaire du moyen de fermeture du récipient par une tige, ou un tube muni d'une canule comprenant une ouverture de laquelle peut couler la composition, soit librement soit par pression par l'utilisateur du récipient. One of these sets may be an assembly for the installation of false eyelashes comprising a pair of false eyelashes and the adhesive composition described above packaged in a container provided with a closure means. The assembly may be provided with a means for applying this composition, as well as a means for gripping the false eyelashes, such as a clamp enabling the false eyelashes to be taken so as to position the base of the false eyelashes. then glue on the eyelid. The means for applying the glue may be integral with the container or separated therefrom. The application means is for example a brush secured to the closure means of the container by a rod, or a tube provided with a cannula comprising an opening which can flow the composition, either freely or by pressure by the user of the container.
L'ensemble peut contenir une ou plusieurs paires de franges de faux cils de longueur différentes, ou des bottes de faux cils de différentes densité, longueur et/ou orientation. Il peut également comprendre d'autres accessoires de maquillage des cils et des paupières tels qu'une brosse à cils, un eye-liner ou un mascara, lesquels produits permettront de finaliser la mise en beauté des cils.

CC27 (rotating at 200 rpm) or 4 blades: ST22 - 4V (rotating at 100 rpm), to check the one that was suitable for the measurement, and choosing a measuring time of 3 minutes.
Préalablement à la mesure, on a placé la composition de l'invention dans un pot de 120 ml (Kola Rond VT3 120 Blanc Pharm) dans une étuve à 25°C pendant 12 heures minimum. Une fois le mobile plongé dans le pot, le niveau de composition doit atteindre le col du pot.  Prior to measurement, the composition of the invention was placed in a 120 ml jar (Kola Rond VT3 120 White Pharm) in an oven at 25 ° C for a minimum of 12 hours. Once the mobile plunged into the pot, the level of composition must reach the neck of the pot.
On vérifie que le mobile est bien choisi en mesurant le pourcentage de déviation des mesures qui sont effectuées toutes les 6 secondes. La valeur de la viscosité de la composition est égale, selon ce protocole, à la moyenne des quinze dernières mesures effectuées par l'appareil pendant le temps de mesure indiqué ci-dessus.  We verify that the mobile is well chosen by measuring the percentage of deviation of the measurements that are made every 6 seconds. The value of the viscosity of the composition is equal, according to this protocol, to the average of the last fifteen measurements made by the apparatus during the measurement time indicated above.
La valeur trouvée était de 2 135 mPa.s.  The value found was 2,135 mPa.s.
Stabilité de la colle Stability of the glue
La stabilité de la viscosité de la colle a été évaluée en plaçant la composition en étuve, à une température de 4°C, 45°C ou 50°C pendant une durée variant de 24 heures à 3 mois. La composition de l'exemple était stable dans toutes ces conditions.  The stability of the viscosity of the glue was evaluated by placing the composition in an oven at a temperature of 4 ° C., 45 ° C. or 50 ° C. for a period ranging from 24 hours to 3 months. The composition of the example was stable under all these conditions.
La stabilité de la couleur de la composition de l'exemple a été évaluée par un Sun Test. Aucun jaunissement de la composition n'a été observé.  The color stability of the composition of the example was evaluated by a Sun Test. No yellowing of the composition was observed.
Pose de faux cils False eyelashes
Les performances de la colle ont été évaluées sur plusieurs personnes en suivant le protocole suivant.  Glue performance was evaluated on several people using the following protocol.
La composition a été déposée à l'aide d'un flacon doté d'une canule sur la base de deux franges complètes de faux cils. La colle est visible au moment de l'application. Son dépôt sur les paupières est transparent et non collant une fois sec.  The composition was deposited using a vial with a cannula on the basis of two full fringes of false eyelashes. The glue is visible at the time of application. Its deposit on the eyelids is transparent and not sticky when dry.
Chaque faux cils a été déposée sur la base des cils d'une personne, et maintenu par une légère pression des doigts pendant 30 secondes jusqu'à séchage de la composition.  Each false eyelash was placed on the base of the eyelashes of a person, and held by gentle finger pressure for 30 seconds until the composition was dried.
Les faux cils sont restés en place sans se décoller pendant au moins 2 jours, généralement entre 3 jours et 5 jours. Ils ont été retirés en plaçant un coton imbibé de lotion démaquillante contenant une huile sur chaque paupière fermée et en le laissant en place sans aucun essuyage pendant quelques instants. Les faux cils ont été ensuite décollés avec une pince en partant d'une de leur extrémité puis en tirant progressivement jusqu'à décollement complet. Ce geste n'a provoqué aucune sensation douloureuse chez l'utilisateur. Les faux cils ont été décollés avec la composition adhésive recouvrant leur frange en un seul geste. Il n'y avait aucun résidu de colle sur la paupière après décollement de l'ensemble. The false eyelashes remained in place without detaching for at least 2 days, usually between 3 days and 5 days. They were removed by placing a cotton pad soaked with cleansing lotion containing an oil on each closed eyelid and leaving it in place without any wiping for a few moments. The false eyelashes were then peeled off with one forceps from one of their ends and then gradually pulling until complete detachment. This movement caused no painful sensation in the user. The false eyelashes were peeled off with the adhesive composition covering their bangs in a single gesture. There was no glue residue on the eyelid after detachment of the whole.
