EXTRAIT DE BOURGEONS DE Castanea sativaEXTRACT OF BEANS OF Castanea sativa
L'invention concerne un extrait de bourgeons de Castanea sativa Elle a 5 également pour objet une composition cosmétique comprenant ledit extrait. Elle se rapporte enfin à un certain nombre d'utilisations cosmétiques, par application topique, de l'extrait et donc de la composition de l'invention. The invention relates to an extract of Castanea sativa buds. It also relates to a cosmetic composition comprising said extract. Finally, it relates to a certain number of cosmetic uses, by topical application, of the extract and therefore of the composition of the invention.
Originaire de l'Europe méridionale et du sud-ouest asiatique, Castanea sativa 10 est une espèce de la famille des Fagacées. Cet arbre, pouvant atteindre 30 m de haut, est très répandu et peuple de nombreuses forêts multiséculaires dans les régions à terrain sableux ou silico-argileux. Il existe plusieurs centaines de variétés provenant de cultures pour l'industrie du bois ou la production de châtaignes. Native to southern Europe and south-west Asia, Castanea sativa 10 is a species in the Fagaceae family. This tree, up to 30 m tall, is very widespread and populates many centuries-old forests in regions with sandy or clay-clay soil. There are several hundred varieties from cultures for the wood industry or the production of chestnuts.
A la connaissance du Demandeur, le châtaigner est utilisé sous différentes formes en cosmétique. Sous forme de farine, il est utilisé comme anti-âge (voir par exemple DE 4107122) ou comme composant de bain moussant (JP 9175993). La ronce du châtaignier a été décrite pour son effet protecteur (voir par exemple KR 00253843), mais également comme agent capillaire (JP 8217641). 20 Le document JP 10226633 décrit l'utilisation pour une activité blanchissante et anti-radicaux libres, d'écorces et de la peau de châtaignes. Enfin, la châtaigne est décrite dans le document JP 2000154121 dans une composition capillaire en présence d'autres extraits tels que notamment Cèdre du Japon. To the knowledge of the Applicant, chestnut is used in various forms in cosmetics. In the form of flour, it is used as an anti-aging agent (see for example DE 4107122) or as a foaming bath component (JP 9175993). The bramble of the chestnut has been described for its protective effect (see for example KR 00253843), but also as a hair agent (JP 8217641). The document JP 10226633 describes the use for whitening activity and anti-free radicals, of bark and the skin of chestnuts. Finally, the chestnut is described in document JP 2000154121 in a hair composition in the presence of other extracts such as in particular Japanese cedar.
Le Demandeur a constaté que d'autres parties de cet arbre en particulier les feuilles, le bois, l'écorce et notamment les bourgeons présentaient des propriétés intéressantes, en particulier dans le domaine cosmétique, par application topique. The Applicant has found that other parts of this tree, in particular the leaves, the wood, the bark and in particular the buds, have interesting properties, in particular in the cosmetic field, by topical application.
Dans la suite de la description, l'invention est plus particulièrement décrite en relation avec les bourgeons. Toutefois, les même conditions d'extraction et les 30 mêmes propriétés décrites par la suite, s'appliquent aux feuilles, bois et écorce. In the following description, the invention is more particularly described in relation to the buds. However, the same extraction conditions and the same properties described below apply to the leaves, wood and bark.
Autrement dit et selon un premier aspect, l'invention concerne un extrait de bourgeons de Castaniea sativa susceptible d'être obtenu par une première étape d'extraction solide/liquide, suivie d'une seconde étape de séparation solide/liquide, puis d'une troisième étape de récupération de la phase liquide. In other words and according to a first aspect, the invention relates to an extract of Castaniea sativa buds capable of being obtained by a first step of solid / liquid extraction, followed by a second step of solid / liquid separation, then of a third stage of recovery of the liquid phase.
Selon une première caractéristique, l'extraction solide/liquide peut être effectuée par différentes techniques bien connues de l'homme du métier, telles que macération, re-macération, digestion, macération dynamique, extraction en lit fluide, extraction assistée par micro-ondes, extraction assistée par ultra-sons, 10 extraction à contre courant, percolation, repercolation, lixiviation, extraction sous pression réduite, diacolation, extraction par fluide supercritique, extraction solideliquide sous reflux continu (soxhlet). Dans un mode de réalisation avantageux, l'extraction est effectuée par macération dynamique à chaud. According to a first characteristic, the solid / liquid extraction can be carried out by different techniques well known to those skilled in the art, such as maceration, re-maceration, digestion, dynamic maceration, extraction in a fluid bed, extraction assisted by microwaves. , ultrasonic assisted extraction, 10 countercurrent extraction, percolation, repercolation, leaching, extraction under reduced pressure, deacolation, extraction by supercritical fluid, solideliquid extraction under continuous reflux (soxhlet). In an advantageous embodiment, the extraction is carried out by dynamic hot maceration.
Selon une autre caractéristique, l'extraction solide/liquide est effectuée à partir de bourgons sous forme fraîche, sèche, fraîche traités par hyperfréquence, ou fraîche traités par hyperfréquence puis séchés, les bourgeons pouvant se présenter en outre sous formne entière, concassée, broyée, ou cryobroyée. According to another characteristic, the solid / liquid extraction is carried out from burgers in fresh, dry, fresh form treated by microwave, or fresh treated by microwave then dried, the buds being able to appear moreover in whole form, crushed, ground. , or freeze-ground.
Par ailleurs, le solvant d'extraction correspondant à la phase liquide est un solvant organique utilisable dans une application cosmétique par voie topique. Le solvant d'extraction est choisi dans le groupe comprenant l'eau, les alcools (éthanol, méthanol, etc.), les glycols (tels que le propylène glycol, le butylène glycol, la glycérine...), seuls ou en mélange. 25 En pratique, le ratio bourgeon/ solvant, pendant l'étape d'extraction, est compris entre 1/99 et 80/20 (en poids). De même, L'extraction est effectuée à une température comprise entre 3 et 1000C, de préférence entre 20 et 60C, pendant quelques minutes à plusieurs jours, en fonction de la méthode d'extraction utilisée. 30 De manière à optimiser l'extraction des composés actifs tout en protégeant ces composés de l'oxydation par l'oxygène de l'air, l'étape d'extraction solide/liquide peut être réalisée sous agitation et sous atmosphère d'azote. Furthermore, the extraction solvent corresponding to the liquid phase is an organic solvent which can be used in a cosmetic application by the topical route. The extraction solvent is chosen from the group comprising water, alcohols (ethanol, methanol, etc.), glycols (such as propylene glycol, butylene glycol, glycerine, etc.), alone or as a mixture . In practice, the bud / solvent ratio, during the extraction step, is between 1/99 and 80/20 (by weight). Likewise, the extraction is carried out at a temperature between 3 and 1000C, preferably between 20 and 60C, for a few minutes to several days, depending on the extraction method used. In order to optimize the extraction of the active compounds while protecting these compounds from oxidation by oxygen in the air, the solid / liquid extraction step can be carried out with stirring and under a nitrogen atmosphere.
Selon l'invention, l'extraction solide/liquide est suivie d'une étape de séparation solide/liquide, l'objectif étant de récupérer la phase liquide contenant la matière active. Cette séparation peut être effectuée par toute technique connue de l'homme du métier, en particulier l'égouttage, le pressage, l'essorage, la centrifugation ou la filtration. According to the invention, the solid / liquid extraction is followed by a solid / liquid separation step, the objective being to recover the liquid phase containing the active material. This separation can be carried out by any technique known to those skilled in the art, in particular draining, pressing, spinning, centrifugation or filtration.
Dans un mode de réalisation avantageux, l'étape de séparation liquide/solide est suivie par au moins une étape de clarification. Cette étape de clarification peut être effectuée par filtration sur plaques, filtration mnembranaire, filtration 10 tangentielle, ou encore par centrifugation. In an advantageous embodiment, the liquid / solid separation step is followed by at least one clarification step. This clarification step can be carried out by plate filtration, membrane filtration, tangential filtration, or even by centrifugation.
Selon un autre mode de réalisation, l'étape de séparation liquide/solide est suivie d'une étape de concentration, laquelle permet d'obtenir une forme liquide concentrée. En pratique, l'étape de concentration est effectuée par évaporation 15 sous vide ou osmose inverse. Bien entendu, l'étape de concentration peut être effectuée directement après l'étape de séparation ou de clarification. According to another embodiment, the liquid / solid separation step is followed by a concentration step, which makes it possible to obtain a concentrated liquid form. In practice, the concentration step is carried out by evaporation under vacuum or reverse osmosis. Of course, the concentration step can be carried out directly after the separation or clarification step.
Postérieurement à l'étape de séparation solide/liquide et dans un autre mode de réalisation, l'extrait obtenu est fractionné, enrichi ou purifié par différentes 20 techniques telles que la filtration membranaire, l'extraction liquide/liquide ou la chromatographie préparative. After the solid / liquid separation step and in another embodiment, the extract obtained is fractionated, enriched or purified by various techniques such as membrane filtration, liquid / liquid extraction or preparative chromatography.
Enfin, en vue d'un conditionnement stérile ou non stérile, les étapes de clarification et/ou de concentration peuvent être suivies d'une étape de filtration 25 stérilisante à 0.22[tm. Finally, for sterile or non-sterile packaging, the clarification and / or concentration steps can be followed by a sterilizing filtration step at 0.22 [tm.
Comme déjà dit, à l'issue de l'étape de séparation, on récupère un extrait sous forme liquide. Pour obtenir un extrait liquide stable dans le temps en terme de contamination bactérienne, de stabilité physico- chimique et de couleur et dans le 30 cas d'un conditionnement non stérile, on incorpore à la phase liquide, le cas échéant avant l'étape de filtration stérilisante, au moins un agent conservateur (ex. As already said, at the end of the separation step, an extract is recovered in liquid form. To obtain a liquid extract which is stable over time in terms of bacterial contamination, physicochemical and color stability and in the case of non-sterile packaging, the liquid phase is incorporated, if necessary before the sterilizing filtration, at least one preservative (ex.
Phénonip ...) dans une concentration comprise entre 1 et lOg/l et un agent antioxydant (ex. acides organiques: ascorbique, citrique...) dans une concentration comprise entre 0.5 et 10 g/l par rapport au volume total de la phase liquide. Phenonip ...) in a concentration between 1 and 10g / l and an antioxidant (e.g. organic acids: ascorbic, citric ...) in a concentration between 0.5 and 10 g / l relative to the total volume of the liquid phase.
Pour obtenir un extrait sous fonne sèche, l'extrait obtenu à l'issue de l'étape 5 de séparation liquide/solide, le cas échéant de clarification et/ou de concentration est séché, avec ou sans agent de conservation et avec ou sans agent texturant (tel que l'amidon, les maltodextrines, les sirops de glucose...), par lyophilisation, atomisation ou évaporation sous vide. To obtain an extract in dry form, the extract obtained at the end of step 5 of liquid / solid separation, where appropriate of clarification and / or concentration is dried, with or without preservative and with or without texturing agent (such as starch, maltodextrins, glucose syrups, etc.), by lyophilization, atomization or evaporation under vacuum.
Selon une autre caractéristique, lorsque l'extrait se présente sous forme liquide, il a une teneur en matière sèche comprise entre 1 et 100 g/kg. Lorsqu'il se présente sous fouine sèche, il a une teneur en matière sèche comprise entre 10 et 1000 g/kg. According to another characteristic, when the extract is in liquid form, it has a dry matter content of between 1 and 100 g / kg. When it comes in a dry marten, it has a dry matter content of between 10 and 1000 g / kg.
L'extrait peut être utilisé dans le domaine cosmétique, en particulier lorsqu'il est appliqué par voie topique. Ainsi, le Demandeur a constaté que l'extrait de l'invention: - stimulait la synthèse des composants essentiels de la matrice extiacellulaire par les cellules du derme, telles que l'élastine, le collagène 20 et l'acide hyaluronique, - avait une activité cytoprotectrice vis à vis de la peau. The extract can be used in the cosmetic field, in particular when applied topically. Thus, the Applicant has found that the extract of the invention: - stimulates the synthesis of essential components of the extiacellular matrix by the dermis cells, such as elastin, collagen 20 and hyaluronic acid, - had a cytoprotective activity with respect to the skin.
En d'autres termes et selon un autre aspect de l'invention, l'extrait précédemment décrit peut être utilisé dans ces applications. 25 Dans un autre aspect, l'invention concerne une composition cosmétique comprenant un extrait de feuilles, d'écorce de bois ou de bourgeons de Castanea sativa, en particulier un extrait de bourgeons obtenu par le procédé ciavant décrit. In other words and according to another aspect of the invention, the extract described above can be used in these applications. In another aspect, the invention relates to a cosmetic composition comprising an extract of leaves, wood bark or buds of Castanea sativa, in particular an extract of buds obtained by the process described above.
En pratique, l'extrait représente entre 0,1 % et 10 % en poids de la composition, préférentiellement entre 0,3 % et 3 %. In practice, the extract represents between 0.1% and 10% by weight of the composition, preferably between 0.3% and 3%.
