Domaine Technique Technical area
La présente invention concerne le domaine des matériaux textiles non tissés destinés à une utilisation cosmétique ou dermo-cosmétique. En particulier, la présente invention est relative à un matériau textile non tissé et sec imprégné d'une composition cosmétique ou dermo- cosmétique, son utilisation cosmétique ou dermo-cosmétique et un procédé de traitement cosmétique ou dermo-cosmétique cutané de la poitrine à l'aide de ce matériau textile. The present invention relates to the field of nonwoven textile materials intended for cosmetic or dermo-cosmetic use. In particular, the present invention relates to a nonwoven and dry textile material impregnated with a cosmetic or dermo-cosmetic composition, its cosmetic or dermo-cosmetic use and a process for cosmetic or dermo-cosmetic skin treatment from the chest to the skin. using this textile material.
Technique antérieure Prior art
Les matériaux textiles non tissés sont de plus en plus utilisés dans le domaine cosmétique par exemple sous forme de patchs ou de masques à appliquer sur le visage, les mains, les pieds et autres zones cutanées pour conférer à la peau différents effets cosmétiques tels qu'un effet hydratant, drainant, rafraîchissant, exfoliant, nettoyant etc. Nonwoven textile materials are increasingly used in the cosmetics field, for example in the form of patches or masks to be applied to the face, hands, feet and other skin areas to give the skin various cosmetic effects such as a moisturizing, draining, refreshing, exfoliating, cleansing effect, etc.
Cependant, ces matériaux doivent en général être utilisés sous forme mouillée que ce soit par application d'une composition cosmétique sur le matériau textile par l'utilisateur juste avant son utilisation ou bien grâce à une composition cosmétique liquide dans lequel le matériau textile baigne jusqu'à son utilisation. However, these materials must generally be used in wet form, whether by application of a cosmetic composition to the textile material by the user just before its use or else by virtue of a liquid cosmetic composition in which the textile material bathes up to to its use.
A titre d'exemple, on peut faire référence aux documents brevets W02015/152013 (Al) et KR20180137901 (A) qui décrivent un matériau textile non tissé destiné à une utilisation cosmétique pour la peau, dans lequel le matériau textile est mouillé lorsqu'il est imprégné d'une composition cosmétique et est destiné à être appliqué mouillé sur la peau. By way of example, reference may be made to patent documents WO2015 / 152013 (A1) and KR20180137901 (A) which describe a non-woven textile material intended for cosmetic use for the skin, in which the textile material is wet when it is used. is impregnated with a cosmetic composition and is intended to be applied wet to the skin.
Le document KR20180137901 (A) a notamment pour objectif de prévenir le séchage du matériau textile avant son utilisation. The aim of the document KR20180137901 (A) is in particular to prevent the drying of the textile material before its use.
Ces dispositifs étant mouillés ou devant être mouillés pour leur application, ces derniers ne sont pas faciles à utiliser pour le consommateur, ni agréables, ni adaptés à être portés sur de longues périodes et en particulier au contact des vêtements. These devices being wet or having to be wet for their application, the latter are not easy for the consumer to use, nor pleasant, nor suitable for being worn for long periods and in particular in contact with clothing.
Par ailleurs, étant donné l'évaporation plus ou moins rapide de la composition cosmétique, ces dispositifs sont destinés à un usage unique et bref conférant un effet cosmétique dit « flash », sur une période optimale pouvant aller de 10 à 30 minutes. Ces dispositifs nécessitent également un conditionnement dans une pochette étanche pour éviter l'évaporation de la composition cosmétique lorsque le matériau textile est fourni pré imprégné par ladite composition. Moreover, given the more or less rapid evaporation of the cosmetic composition, these devices are intended for a single and brief use conferring a so-called cosmetic effect. "Flash", over an optimal period ranging from 10 to 30 minutes. These devices also require packaging in a sealed pouch to prevent evaporation of the cosmetic composition when the textile material is supplied pre-impregnated with said composition.
Ainsi, ces dispositifs ne permettent pas d'obtenir un effet cosmétique ou dermo-cosmétique prolongé, ni un effet cosmétique ou dermo-cosmétique en profondeur notamment sur la peau puisqu'ils sont destinés à une utilisation brève. Thus, these devices do not make it possible to obtain a prolonged cosmetic or dermo-cosmetic effect, nor an in-depth cosmetic or dermo-cosmetic effect, in particular on the skin since they are intended for brief use.
La présente invention a donc pour objectif de fournir un matériau textile destiné à être utilisé dans le domaine cosmétique ou dermo-cosmétique, qui soit facile, rapide à mettre en œuvre, permettant d'obtenir un effet cosmétique ou dermo-cosmétique topique en particulier cutané, immédiat, prolongé et en profondeur. The objective of the present invention is therefore to provide a textile material intended for use in cosmetics or dermo-cosmetics, which is easy and quick to use, making it possible to obtain a topical cosmetic or dermo-cosmetic effect, in particular on the skin. , immediate, prolonged and in depth.
Un autre objectif de la présente invention est de fournir un matériau textile destiné à être utilisé dans le domaine cosmétique ou de la dermo-cosmétique qui soit simple et économique à réaliser, respectueux de l'environnement, facilement adaptable aux consommateurs, et aux différentes utilisations cosmétiques ou dermo-cosmétiques envisagées, que ce soit en termes de forme, de taille du matériau textile ou encore de composition cosmétique ou dermo-cosmétique comprise dans ledit matériau. Another objective of the present invention is to provide a textile material intended for use in cosmetics or dermo-cosmetics which is simple and economical to produce, respectful of the environment, easily adaptable to consumers, and to different uses. cosmetics or dermo-cosmetics envisaged, whether in terms of shape, size of the textile material or else of cosmetic or dermo-cosmetic composition included in said material.
Un autre objectif de la présente invention est de fournir un matériau textile destiné à être utilisé dans le domaine cosmétique ou dermo-cosmétique qui soit agréable et adapté à être porté sur une période prolongée, présentant un toucher sec, doux et soyeux, facile à appliquer et à enlever, présentant une bonne tenue, une bonne consistance. Another objective of the present invention is to provide a textile material intended for use in cosmetics or dermo-cosmetics which is pleasant and suitable for being worn over a prolonged period, having a dry, soft and silky feel, easy to apply. and to remove, having a good hold, a good consistency.
Un autre objectif de la présente invention est de fournir un matériau textile destiné à être utilisé dans le domaine cosmétique ou de la dermo-cosmétique qui soit réalisé à partir de matières naturelles, qui soit écologique et totalement biodégradable Another objective of the present invention is to provide a textile material intended for use in cosmetics or dermo-cosmetics which is made from natural materials, which is ecological and completely biodegradable.

The fibers of a non-woven textile material can be bonded by friction and / or cohesion and / or adhesion, to the exclusion of paper and products obtained by weaving, knitting, tufting, stitching, incorporating binding threads or filaments or felted by wet pressing whether or not they are needled.
Le matériau textile non tissé selon la présente invention est destiné à une utilisation cosmétique ou dermo-cosmétique topique. Par voie topique on fait référence à une application sur la peau, les muqueuses, les phanères tels que les ongles, les poils et les cheveux. Le matériau textile selon la présente invention est de préférence destiné à une utilisation sur la peau, par exemple de la poitrine, du cou, du thorax, le dos, du visage, des mains, des pieds, les bras, les jambes de préférence la poitrine. The nonwoven textile material according to the present invention is intended for topical cosmetic or dermo-cosmetic use. Topically, reference is made to an application to the skin, mucous membranes, integuments such as nails, body hair and hair. The textile material according to the present invention is preferably intended for use on the skin, for example the chest, neck, thorax, back, face, hands, feet, arms, legs preferably the skin. chest.
Le matériau textile non tissé selon la présente invention est sec, ce qui signifie que ledit matériau imprégné d'une composition cosmétique ou dermo-cosmétique n'est ni mouillé, ni humide, en particulier au toucher. The nonwoven textile material according to the present invention is dry, which means that said material impregnated with a cosmetic or dermo-cosmetic composition is neither wet nor damp, in particular to the touch.
De préférence, le matériau textile selon la présente invention est considéré comme sec lorsqu'il présente un taux d'humidité compris entre 0,1 et 15 %, de préférence entre 0.5 % et 10 %, de préférence encore de pas plus de 5 % en poids par rapport au poids total du matériau. Selon un aspect encore préféré, le matériau textile non tissé sec selon la présente invention présente un taux d'humidité inférieur à 5 % en poids par rapport au poids total du matériau.Preferably, the textile material according to the present invention is considered to be dry when it has a moisture content of between 0.1 and 15%, preferably between 0.5% and 10%, more preferably not more than 5%. by weight relative to the total weight of the material. According to a still preferred aspect, the dry nonwoven textile material according to the present invention has a moisture content of less than 5% by weight relative to the total weight of the material.
Le caractère « sec » du matériau textile peut être déterminé au toucher ou bien par toutes méthodes de mesure d'humidité connues de l'art antérieur telles que l'utilisation d'un humidimètre numérique ou digital pour textiles (par exemple TMT-425 ou TEM-1 commercialisés par Checkline Europe. The "dry" character of the textile material can be determined by touch or by any moisture measurement methods known from the prior art such as the use of a digital or digital moisture meter for textiles (for example TMT-425 or TEM-1 marketed by Checkline Europe.
De préférence, le matériau textile selon la présente invention est considéré comme sec lorsqu'il présente un taux d'humidité compris entre 0,1 et 15 %, de préférence entre 0.5 % et 10 %, de préférence encore de pas plus de 5 %, déterminé par humidimètre. Preferably, the textile material according to the present invention is considered to be dry when it has a moisture content of between 0.1 and 15%, preferably between 0.5% and 10%, more preferably not more than 5%. , determined by moisture meter.

According to a still preferred aspect, the dry nonwoven textile material according to the present invention has a moisture content of less than 5% determined by a moisture meter.
Le fait de disposer d'un matériau textile non tissé sec permet avantageusement de disposer d'un matériau textile prêt à l'emploi, ne nécessitant pas d'être baigné dans la composition cosmétique ou dermo-cosmétique avant application par le consommateur et ne nécessitant pas un conditionnement particulier. Enfin, cela permet également de disposer d'un matériau textile agréable à porter et adapté à être porté sur de longues périodes. The fact of having a dry nonwoven textile material advantageously makes it possible to have a ready-to-use textile material, not requiring to be bathed in the cosmetic or dermo-cosmetic composition before application by the consumer and not requiring not a particular conditioning. Finally, this also makes it possible to have a textile material that is pleasant to wear and suitable for being worn over long periods.
Le caractère sec du matériau textile selon la présente invention est obtenu grâce à une étape de séchage du matériau après son imprégnation avec la composition cosmétique ou dermo-cosmétique, ou alternativement par une étape de séchage des fibres textiles après leur imprégnation avec la composition. The dryness of the textile material according to the present invention is obtained by virtue of a step of drying the material after its impregnation with the cosmetic or dermo-cosmetic composition, or alternatively by a step of drying the textile fibers after their impregnation with the composition.
Par « micro encapsulé » on fait référence au fait que le composé cosmétique ou dermo- cosmétique actif est emprisonné dans des microcapsules à parois polymériques par une des méthodes d'encapsulation connues de l'Homme du métier. On peut notamment faire référence aux techniques d'encapsulation par polycondensation, polymérisation, spray- drying, spray-cooling, lit d'air fluidisé, extrusion, précipitation, diffusion de solvant, coacervation (simple ou complexe). The term “microencapsulated” refers to the fact that the active cosmetic or dermo-cosmetic compound is trapped in microcapsules with polymeric walls by one of the encapsulation methods known to those skilled in the art. Reference may in particular be made to the techniques of encapsulation by polycondensation, polymerization, spray-drying, spray-cooling, fluidized air bed, extrusion, precipitation, diffusion of solvent, coacervation (simple or complex).
La micro encapsulation permet de libérer le composé cosmétique ou dermo-cosmétique actif lors de l'éclatement des microcapsules dans lesquelles il se trouve par frottement mécanique ou en présence de certaines conditions de température, d'humidité, de pH ou autres, induisant leur délitement, éclatement ou par diffusion lente. La micro encapsulation du composé cosmétique ou dermo-cosmétique actif compris dans la composition sert de véhicule au composé actif, permet de fixer le composé actif sur le matériau textile, permet une libération prolongée du composé actif et permet in fine d'obtenir un effet cosmétique ou dermo-cosmétique amélioré. Microencapsulation makes it possible to release the active cosmetic or dermo-cosmetic compound during the bursting of the microcapsules in which it is found by mechanical friction or in the presence of certain temperature, humidity, pH or other conditions, inducing their disintegration. , bursting or by slow diffusion. The microencapsulation of the active cosmetic or dermo-cosmetic compound included in the composition serves as a vehicle for the active compound, makes it possible to fix the active compound on the textile material, allows a prolonged release of the active compound and ultimately makes it possible to obtain an improved cosmetic or dermo-cosmetic effect.
Les microcapsules dans lesquelles se trouve le composé cosmétique ou dermo-cosmétique actif sont constituées d'un polymère choisi parmi les résines aminoplastes c'est-à-dire résultant de la polycondensation d'un aldéhyde avec une amine ou un amide, ou les polysiloxanes, la gélatine ou l'alginate. De préférence encore, lesdites microcapsules sont constituées d'un polymère de type urée-formol ou de type mélamine-formol. The microcapsules in which the active cosmetic or dermo-cosmetic compound is found consist of a polymer chosen from aminoplast resins, that is to say resulting from the polycondensation of an aldehyde with an amine or an amide, or polysiloxanes , gelatin or alginate. More preferably, said microcapsules consist of a polymer of urea-formalin type or of melamine-formalin type.
De préférence, les microcapsules selon l'invention sont fabriquées par polymérisation in situ des polymères constituant la paroi des microcapsules avec le composé cosmétique ou dermo-cosmétique actif. Preferably, the microcapsules according to the invention are manufactured by in situ polymerization of the polymers constituting the wall of the microcapsules with the active cosmetic or dermo-cosmetic compound.
Les microcapsules comprenant le composé cosmétique ou dermo-cosmétique actif peuvent avantageusement être revêtues d'une pellicule de liants polymères tels que le polyuréthane, le polysiloxane, les polyacrylates, les latex pour leur conférer une meilleure résistance à l'éclatement mais aussi favoriser leur accroche au matériau textile non tissé selon la présente invention. The microcapsules comprising the active cosmetic or dermo-cosmetic compound can advantageously be coated with a film of polymer binders such as polyurethane, polysiloxane, polyacrylates, latexes to give them better resistance to bursting but also to promote their adhesion. to the non-woven textile material according to the present invention.
Selon la présente invention, la dimension des microcapsules dans lesquelles se trouve le composé cosmétique ou dermo-cosmétique actif peut aller du nanomètre au micromètre, de façon préférée les microcapsules présentent une dimension comprise entre 100 nm et 200 pm, de façon encore préférée entre 150 nm et 100 pm et de façon particulièrement préférée entre 1 pm et 100 pm. L'Homme du métier veillera à choisir la dimension des microcapsules en fonction de la vitesse de libération du composé cosmétique ou dermo-cosmétique actif souhaitée. En effet, les microcapsules de dimension élevée, par exemple supérieure à 150 pm auront tendance à s'éclater plus rapidement que celles de plus faible taille. According to the present invention, the size of the microcapsules in which the active cosmetic or dermo-cosmetic compound is found can range from nanometer to micrometer, preferably the microcapsules have a size between 100 nm and 200 μm, more preferably between 150. nm and 100 μm and particularly preferably between 1 μm and 100 μm. Those skilled in the art will take care to choose the size of the microcapsules as a function of the release rate of the desired active cosmetic or dermo-cosmetic compound. This is because microcapsules of large size, for example greater than 150 μm, will tend to burst more quickly than those of smaller size.
La méthode d'encapsulation du composé cosmétique ou dermo-cosmétique actif dans les microcapsules, le type de polymère constituant les microcapsules dans lequel se trouve le composé cosmétique ou dermo-cosmétique actif ainsi que la dimension de ces microcapsules pourront être ajustés selon l'utilisation cosmétique ou dermo-cosmétique visée, le ou les composé(s) cosmétique(s) ou dermo-cosmétique(s) actif(s) utilisés, la vitesse de libération du ou des composé(s) cosmétique(s) ou dermo-cosmétique(s) actif(s) souhaitée, la résistance mécanique souhaitée et / ou les contraintes de fabrication. The method of encapsulating the active cosmetic or dermo-cosmetic compound in the microcapsules, the type of polymer constituting the microcapsules in which the active cosmetic or dermo-cosmetic compound is found, as well as the size of these microcapsules can be adjusted according to the use. target cosmetic or dermo-cosmetic, the active cosmetic or dermo-cosmetic compound (s) used, the release rate of the cosmetic or dermo-cosmetic compound (s) desired active agent (s), desired mechanical strength and / or manufacturing constraints.

Preferably, the textile material according to the present invention is impregnated with the cosmetic or dermo-cosmetic composition by soaking or by spraying.
De façon avantageuse, l'imprégnation du matériau textile selon l'invention permet d'y incorporer une concentration pondérale de composé actif suffisante pour l'utilisation cosmétique ou dermo-cosmétique visée. Advantageously, the impregnation of the textile material according to the invention makes it possible to incorporate therein a concentration by weight of active compound sufficient for the cosmetic or dermo-cosmetic use targeted.
De préférence, le matériau textile selon l'invention est obtenu par hydro-enchevêtrement croisé de fibres de textiles discontinues, en particulier de fibres de coton. Preferably, the textile material according to the invention is obtained by crossed hydroentanglement of staple textile fibers, in particular cotton fibers.
Selon un mode de réalisation particulier, le matériau textile selon la présente invention est obtenu par une étape d'enchevêtrement croisé des fibres textiles discontinues par jet d'eau suivie d'une étape d'imprégnation par trempage ou pulvérisation du matériau textile non tissé avec une composition cosmétique ou dermo-cosmétique telle que définie précédemment suivie d'une étape de séchage par exemple à une température comprise entre 60 et 150 °C, pendant 30 secondes à 2 minutes, de préférence à 150°C pendant 60 secondes. De préférence, le matériau textile selon l'invention est fabriqué par enchevêtrement croisé des fibres textiles discontinues par jet d'eau ce qui permet de former une feuille de matériau textile non tissé uniquement à l'aide de la puissance hydraulique sans avoir recours à un composé chimique, ce qui rend ce matériau hautement tolérable au niveau topique et en particulier cutané mais également doux et soyeux au toucher. According to a particular embodiment, the textile material according to the present invention is obtained by a step of crossed entanglement of the discontinuous textile fibers by water jet followed by a step of impregnation by dipping or spraying the nonwoven textile material with a cosmetic or dermo-cosmetic composition as defined above followed by a drying step, for example at a temperature between 60 and 150 ° C, for 30 seconds to 2 minutes, preferably at 150 ° C for 60 seconds. Preferably, the textile material according to the invention is produced by cross-entangling the discontinuous textile fibers by water jet, which makes it possible to form a sheet of non-woven textile material only using hydraulic power without having to resort to a chemical compound, which makes this material highly tolerable topically and in particular on the skin, but also soft and silky to the touch.
Le matériau textile peut comprendre une couche de support en matériau tissé, non tissé ou sous forme de gel, de préférence non tissé, visant à faciliter sa manipulation, à former une barrière occlusive, à favoriser sa solidité, à favoriser sa solidité, à favoriser sa flexibilité, à faciliter son enlèvement et / ou de favoriser son maintien sur la surface sur laquelle il est appliqué.
