Abstract
Description
Le maintien de la beauté, souplesse, santé de la peau humaine nécessite des soins. La recherche de l'lndustrie cosmétique et dermopharmaceutique s'efforce de trouver les remèdes nécessaires aux maux auxquels la peau est exposée quotidiennement: irradiation solaire, pollution chimique, stress, vieillissement génétique, déshydratation...Maintaining the beauty, suppleness, health of human skin requires care. Research in the cosmetic and dermopharmaceutical industry strives to find the remedies necessary for the ailments to which the skin is exposed daily: solar irradiation, chemical pollution, stress, genetic aging, dehydration ...
Un nombre toujours croissant de produits essaie de répondre aux besoins plus ou moins spécifiques des consommateurs.An ever-increasing number of products are trying to meet the more or less specific needs of consumers.
L'hydratation de l'épiderme et l'apport nutritif en vitamines et en micronutriments sont des domaines particuliérement étudiés par la recherche cosmétique.The hydration of the epidermis and the nutritive supply of vitamins and micronutrients are areas particularly studied by cosmetic research.
Néanmoins, il reste un vaste champ libre pour découvrir des nouvelles solutions avantageuses pour nourrir et hydrater la peau.However, there is still a wide field to discover new beneficial solutions to nourish and hydrate the skin.
L'objet de la présente invention est la découverte que l'extrait d'une microalgue appelée Haematococcus pluvialis possède des activités bénéfiques pour la peau, et que l'association avec un polysaccharide d'origine microbienne est particulièrement efficace dans des produits cosmétiques hydratants et nutritifs.The object of the present invention is the discovery that the extract of a microalga called Haematococcus pluvialis has beneficial activities for the skin, and that the association with a polysaccharide of microbial origin is particularly effective in moisturizing cosmetic products and nutritious.
La microalgue Haematococcus pluvialis ne pousse que dans des régions bien spécifiques du globe, en particulier dans des eaux douces, pures, non polluées, bien ensoleillées. Riche en oligo-éléments et en vitamines, en protéines et carbohydrates, elle posséde des vertus énergisantes, régénératrices et stimulantes par voie d'absorption orale. Nous avons découvert que les extraits de cette algue possèdent aussi des effets bénéfiques par voie topique.The microalga Haematococcus pluvialis only grows in very specific regions of the globe, in particular in fresh, pure, unpolluted, very sunny waters. Rich in trace elements and vitamins, proteins and carbohydrates, it has energizing, regenerative and stimulating properties through oral absorption. We have discovered that extracts from this alga also have beneficial effects topically.
Le problème de beaucoup de substances ou composants actifs utilisés en cosmétique réside néanmoins dans le fait que l'absorption au travers l'épiderme puisse être soit trop rapide, soit trop faible. Beaucoup de produits agissant soit en tant qu'aide à la pénétration, soit comme ralentissant l'effet flash d'une pénétration trop rapide, ont été découverts et proposés.The problem with many active substances or components used in cosmetics nevertheless lies in the fact that absorption through the epidermis can be either too rapid or too weak. Many products acting either as a penetration aid, or as slowing the flash effect of too rapid penetration, have been discovered and offered.
Le brevet FR 2688222 décrit l'obtention d'un oligo- ou polysaccharide de composition glucuronique à partir du micro-organisme Rhizobium meliloti et l'utilisation des propriétés gélifiantes de ces molécules dans différents domaines, y compris celui de la cosmétique.The patent FR 2688222 describes the obtaining of an oligo- or polysaccharide of glucuronic composition from the microorganism Rhizobium meliloti and the use of the gelling properties of these molecules in various fields, including that of cosmetics.
La formation de ces gels nécessite néanmoins la présence de cations mono- ou divalents, et les gels ainsi obtenus ne sont pas bien adaptés aux exigences galéniques cosmétiques: ils sont plutôt compacts, thermosensibles et cassants.The formation of these gels nevertheless requires the presence of mono- or divalent cations, and the gels thus obtained are not well suited to galenical cosmetic requirements: they are rather compact, heat-sensitive and brittle.
La découverte objet de la présente invention est le fait que l'utilisation cosmétique des extraits d'Haematococcus pluvialis améliore l'état superficiel de la peau et que l'utilisation des oligo- et polymères d'acide glucuronique à une concentration suffisamment faible qui évite la gélification, permet de former un film de seulement quelques couches moléculaires sur la peau: en associant l'extrait de microalgues d'Haematococcus plu via lis aux polysaccharides glucuroniques au sein d'une composition cosmétique on obtient des meilleurs résultats d'hydratation et de régénération cellulaire de la peau qu'avec l'extrait d'Haematococcus pluvialis seul.The discovery object of the present invention is the fact that the cosmetic use of extracts of Haematococcus pluvialis improves the surface state of the skin and that the use of oligo- and polymers of glucuronic acid at a sufficiently low concentration which avoids gelation, makes it possible to form a film of only a few molecular layers on the skin: by combining Haematococcus microalgae extract plus via lily with glucuronic polysaccharides within a cosmetic composition, better hydration and cell regeneration of the skin than with Haematococcus pluvialis extract alone.
Quelques exemples non limitatifs vont illustrer l'invention.Some nonlimiting examples will illustrate the invention.
Exemple n" 1: Obtention du mélange de polysaccharide et d'extrait d'algue:
La souche Rhizobium meliloti choisie, en particulier Rhizobium meliloti NCIMB 40472 est cultivée sur un milieu contenant du saccharose, de l'extrait de levure et des sels phosphoriques de potassium, de magnésium et de sodium pendant 48 heures, à 30"C et à pH 7.Example No. 1: Obtaining the mixture of polysaccharide and algae extract:
The selected Rhizobium meliloti strain, in particular Rhizobium meliloti NCIMB 40472, is cultivated on a medium containing sucrose, yeast extract and phosphoric salts of potassium, magnesium and sodium for 48 hours, at 30 ° C. and at pH 7.
Après élimination des micro-organismes par filtration tangentielle, on conserve le filtrat par des substances antimicrobiennes appropriées.After elimination of the microorganisms by tangential filtration, the filtrate is preserved by suitable antimicrobial substances.
Par ailleurs, on prépare un extrait d'Haematococcus pluvialis en macérant les microalgues lyophilisées ou atomisées dans un excipient aqueux ou hydroglycolique, suivie d'une filtration, clarification, décoloration, éventuellement conservation.Furthermore, a Haematococcus pluvialis extract is prepared by macerating the lyophilized or atomized microalgae in an aqueous or hydroglycolic excipient, followed by filtration, clarification, discoloration, possibly preservation.
L'avantage des extraits de cette microalgue réside dans un ratio favorable d'activité biologique sur matière sèche (et couleur associée), ce qui est souvent problématique en phytothérapie cosmétique. Les extraits sont stables, sans forte odeur et facilement utilisés dans tous type de produit cosmétique.The advantage of the extracts of this microalga lies in a favorable ratio of biological activity on dry matter (and associated color), which is often problematic in cosmetic phytotherapy. The extracts are stable, odorless and easily used in all types of cosmetic products.
Les solvants d'extraction pour la préparation des extraits objets du présent brevet peuvent être choisis parmi l'eau, le propylène glycol, le butylène glycol, la glycérine, le polyéthylène glycol, les éthers méthyliques ou éthyliques des diglycols, les polyols cycliques, les diglycols éthoxylés ou propoxylés ou tout mélange de ces solvants.The extraction solvents for the preparation of the extracts which are the subject of this patent can be chosen from water, propylene glycol, butylene glycol, glycerin, polyethylene glycol, methyl or ethyl ethers of diglycols, cyclic polyols, ethoxylated or propoxylated diglycols or any mixture of these solvents.
Les extraits peuvent être obtenus par macération de la plante dans le solvant d'extraction, pendant une durée plus ou moins longue. A la place de la macération simple, on peut employer des techniques à contre courant, la décoction, la lixiviation, l'extraction à l'aide d'ultrasons, de micro-ondes.The extracts can be obtained by maceration of the plant in the extraction solvent, for a more or less long period. Instead of simple maceration, countercurrent techniques can be used, decoction, leaching, extraction using ultrasound, microwaves.
Pour certaines applications cosmétiques il peut s'avérer utile de préparer un extrait sec à partir de l'extrait liquide. Ced peut être réalisé par les techniques classiques de précipitation, de séchage, d'évaporation, d'atomisation ou de lyophilisation. For certain cosmetic applications it may prove useful to prepare a dry extract from the liquid extract. Ced can be achieved by conventional techniques of precipitation, drying, evaporation, atomization or lyophilization.
La composition finale destinée à être utilisée dans un produit cosmétique ou dermopharmaceutique consiste en un mélange du filtrat contenant le polysaccharide et l'extrait d'algues, en une proportion d'environ 10:1.The final composition intended for use in a cosmetic or dermopharmaceutical product consists of a mixture of the filtrate containing the polysaccharide and the algae extract, in a proportion of approximately 10: 1.
Cet exemple n'est pas limitatif; les proportions de mélange du filtrat bactérien avec l'extrait d'Haematococcus pluvialis peuvent varier de 1:1 à 1000:1, les conditions de culture de Rhizobium meliloti peuvent varier dans les limites raisonnables et compatibles avec le métabolisme de Rhizobium meliloti (pH 4-8, température 2040 C, composition en sucre: glucose, fructose, saccharose, milieu de culture synthétique ou contenant des peptones, des additifs vitaminés, etc.).This example is not limitative; the mixing proportions of the bacterial filtrate with the Haematococcus pluvialis extract can vary from 1: 1 to 1000: 1, the culture conditions of Rhizobium meliloti can vary within reasonable limits and compatible with the metabolism of Rhizobium meliloti (pH 4 -8, temperature 2040 C, sugar composition: glucose, fructose, sucrose, synthetic culture medium or one containing peptones, vitamin additives, etc.).
Exemple n" 2: Efficacité cosmétique
Un gel cosmétique a été formulé contenant 3% du mélange de polysaccharide et d'extrait d'Haematococcus pluvialis. Ce gel a été appliqué quotidiennement par un panel de 10 volontaires possédant la peau sèche et rugueuse au niveau de la jambe. Sur l'autre jambe, un gel placebo a été appliqué.Example No. 2: Cosmetic efficacy
A cosmetic gel has been formulated containing 3% of the mixture of polysaccharide and Haematococcus pluvialis extract. This gel was applied daily by a panel of 10 volunteers with dry and rough skin on the leg. On the other leg, a placebo gel was applied.
Une étude d'hydratation au Cornéomètre (mesure de l'impédance de surface) a été menée en parallèle avec une étude des couches cornéocytaires par microscopie électronique à balayage (MEB).A hydration study with the Cornéometer (measurement of the surface impedance) was carried out in parallel with a study of the corneocyte layers by scanning electron microscopy (SEM).
Après 3 semaines d'application, la surface de la peau traitée au mélange polysaccharidelextrait d'algue est nettement plus hydratée et moins rugueuse que la peau traitée au placebo: les valeurs d'hydratation lues au cornéomètre ont augmenté de +15%, les images en MEB montrent un lissage et une meilleure adhésion cellulaire.After 3 weeks of application, the surface of the skin treated with the polysaccharide mixture of seaweed extract is clearly more hydrated and less rough than the skin treated with placebo: the hydration values read by the corneometer increased by + 15%, the images in SEM show smoothing and better cell adhesion.
Une deuxième étude a été effectuée pour comparer l'effet du polysaccharide seul et l'extrait d'Haematococcus pluvialis seul. Alors qu'aucune amélioration significative ne pouvait être constatée aux concentrations d'utilisation identique,
L'extrait d'Haematococcus pluvialis seul améliore l'état de la peau quand on l'utilise à une concentration 5-10 fois plus élevée. Son prix et sa couleur ainsi que l'odeur limitent cependant l'intérêt de cette solution.A second study was carried out to compare the effect of the polysaccharide alone and the extract of Haematococcus pluvialis alone. While no significant improvement could be seen at the concentrations of identical use,
The extract of Haematococcus pluvialis alone improves the condition of the skin when used at a concentration 5-10 times higher. Its price and its color as well as the odor however limit the interest of this solution.
