Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

ASSOCIATION D'AGENTS ACTIFS EXTRAITS D'ALGUES ET LES COMPOSITIONS COSMETIQUES COMPRENANT CETTE ASSOCIATION.  ASSOCIATION OF ACTIVE AGENTS EXTRACTED FROM ALGAE AND COSMETIC COMPOSITIONS COMPRISING THE ASSOCIATION.

L'invention concerne le domaine du soin de la peau et s'intéresse tout particulièrement à l'utilisation d'agents actifs extraits d'algues pour la préparation de ces compositions cosmétiques ou dermatologiques.  The invention relates to the field of skin care and is particularly interested in the use of active agents extracted from algae for the preparation of these cosmetic or dermatological compositions.

On a décrit dans l'art antérieur l'utilisation d'extraits de macrocystis en cosmétique (KELPADELIE extrait sec de la société SECMA). Il a également été proposé par exemple dans les brevets français No. 9105963 ou 9114120 d'utiliser des extraits de tétraselmis ou une suspension de tétraselmis.  It has been described in the prior art the use of macrocystis extracts in cosmetics (KELPADELIE dry extract from the company SECMA). It has also been proposed for example in French Pat. Nos. 9105963 or 9114120 to use tetraselmis extracts or a suspension of tetraselmis.

La demanderesse a maintenant mis au point une nouvelle association d'extraits d'algues, remarquable pour le soin visage ou du corps, et particulièrement efficace pour l'amélioration du relief et du micro-relief cutanés, et notamment utile pour diminuer la profondeur des rides.  The applicant has now developed a new combination of extracts of algae, remarkable for the facial or body care, and particularly effective for the improvement of the relief and micro-relief cutaneous, and particularly useful for reducing the depth of the skin. wrinkles.

Cette association comprend ou est constituée : - d'un extrait d'une algue pluricellulaire géante : macrocystis pyrifera (L) C. Agardh lessoniacées, et - d'un extrait d'une algue unicellulaire tétraselmis suecica chlorodendracées (synonymes platymonas, aulacochlamys prasinocladus et pyramichlamys).  This association comprises or consists of: - an extract of a giant multi-cellular algae: macrocystis pyrifera (L) C. Agardh lessoniaceae, and - an extract of a unicellular alga tetraselmis suecica chlorodendracées (synonyms platymonas, aulacochlamys prasinocladus and pyramichlamys).

L'extrait de macrocystis est obtenu par extraction à l'aide d'un milieu solvant constitué de 2-méthyl propane- 1,3-diol et d'eau de mer partiellement dessalée.  The macrocystis extract is obtained by extraction using a solvent medium consisting of 2-methylpropane-1,3-diol and partially desalinated seawater.

Avantageusement, le 2 methylpropane-1,3-diol représente entre 1 et 60 % en poids du solvant.  Advantageously, the 2-methylpropane-1,3-diol represents between 1 and 60% by weight of the solvent.

On préfère utiliser une eau de mer partiellement dessalée dont la salinité résiduelle est comprise entre 2 et 50g/l, avec un rapport entre le sodium et le magnésium  It is preferred to use partially desalinated seawater whose residual salinity is between 2 and 50 g / l, with a ratio between sodium and magnesium

<Desc/Clms Page number 2><Desc / Clms Page number 2>

compris entre 1 et 6 et un rapport entre le sodium et le calcium compris entre 2 et 12.  between 1 and 6 and a ratio between sodium and calcium of between 2 and 12.

De préférence, l'extraction est réalisée : - soit à partir d'algue macrocystis sèche à raison de 1 à 0,1 part pour 1 part de milieu d'extraction, - soit à partir d'algue macrocystis fraîche à raison de 1 à 5 parts pour 1 part de milieu d'extraction.  Preferably, the extraction is carried out: either from dried macrocystis seaweed at a rate of 1 to 0.1 parts per 1 part of extraction medium, or from fresh macrocystis algae at a rate of 1 to 5 parts for 1 part extraction medium.

L'extrait de tétraselmis est avantageusement préparé à partir d'une culture pure de la souche algale dans de l'eau de mer de salinité standard de l'ordre de 35g/1, telle que trouvée dans l'Océan Atlantique.  The tetraselmis extract is advantageously prepared from a pure culture of the algal strain in standard salinity seawater of the order of 35 g / l, as found in the Atlantic Ocean.

La culture est concentrée par centrifugation de telle sorte que la pâte d'algue obtenue permette un éclatement aisé des cellules par une technique appropriée telle que les ultrasons, un choc hyperbar, un broyage mécanique à l'aide de micro-billes.  The culture is concentrated by centrifugation so that the obtained alga paste allows an easy bursting of the cells by a suitable technique such as ultrasound, hyperbaric shock, mechanical grinding using microbeads.

La concentration cellulaire est comprise entre 40 millions et 2 milliards de cellule/gramme.  The cell concentration is between 40 million and 2 billion cells / gram.

L'extrait de tétraselmis est le broyat cellulaire entier ou la partie débarrassée des débris membranaires insolubles par filtration et/ou centrifugation.  The tetraselmis extract is the whole cell homogenate or the part freed from insoluble membrane debris by filtration and / or centrifugation.

Ainsi, l'extrait d'algue tétraselmis est de préférence obtenu par dispersion dans de l'eau de mer standard à une salinité de 35 g/1, de cellules éclatées a une concentration comprise entre 1 et 400 millions de cellules par ml. Selon une forme de réalisation particulière, les débris membranaires des algues sont éliminés.  Thus, the tetraselmis algae extract is preferably obtained by dispersion in standard seawater at a salinity of 35 g / l, cells exploded at a concentration of between 1 and 400 million cells per ml. According to a particular embodiment, the membrane debris of the algae are eliminated.

Dans l'association selon l'invention, la proportion de l'extrait de macrocystis par rapport à l'extrait de tétraselmis est comprise entre 1/10 et 10/1 et de préférence entre 40/60 et 60/40.  In the combination according to the invention, the proportion of the macrocystis extract relative to the tetraselmis extract is between 1/10 and 10/1 and preferably between 40/60 and 60/40.

L'invention a également pour objet des compositions cosmétiques ou éventuellement dermatologiques, comprenant une association telle que définie précédemment.  The invention also relates to cosmetic or possibly dermatological compositions, comprising an association as defined above.

Ces compositions cosmétiques comprennent entre 1 et 100 % en poids de l'association des extraits définis précédemment. Elles peuvent donc comprendre d'autres substances actives ou non généralement utilisées en cosmétique.  These cosmetic compositions comprise between 1 and 100% by weight of the combination of the extracts defined above. They can therefore include other active substances or not generally used in cosmetics.

Les compositions cosmétiques selon l'invention sont particulièrement efficaces pour l'amélioration du relief et du micro-relief cutanés et sont donc utiles pour diminuer la profondeur des rides.  The cosmetic compositions according to the invention are particularly effective for the improvement of the cutaneous relief and micro-relief and are therefore useful for reducing the depth of wrinkles.

En effet, comme le montre les résultats ci-dessous, la Demanderesse a mis en évidence une efficacité antirides de l'association de ces extraits qui est très supérieure à l'efficacité antirides de l'un ou de l'autre extrait seul : - Efficacité antirides d'un extrait de macrocystis pyrifera (2- methylpropane-1,3-diol 20 %, eau de mer dessalée à 17g/l, 1 kg d'algue sèche pour 10kg d'extrait) : 15,8 % de réduction du volume des rides et 82 % des volontaires montrant un effet favorable (test réalisé sur 11 femmes après 4 semaines d'utilisation).  Indeed, as shown by the results below, the Applicant has demonstrated an anti-wrinkle effectiveness of the combination of these extracts which is much greater than the anti-wrinkle effectiveness of one or the other extract alone: Anti-wrinkle efficacy of an extract of macrocystis pyrifera (2-methylpropane-1,3-diol 20%, seawater desalted at 17g / l, 1 kg of dry algae for 10kg of extract): 15,8% reduction the volume of wrinkles and 82% of volunteers showing a favorable effect (test performed on 11 women after 4 weeks of use).

- L'efficacité antirides d'un extrait de tétraselmis suecica (eau de mer salée à 35 g/1, contenu cellulaire de l'équivalent de 16 millions de cellules/ml) n'a pu être mis en évidence (pas d'effet).  - The anti-wrinkle efficacy of a tetraselmis suecica extract (salt water 35 g / l, cell contents equivalent to 16 million cells / ml) could not be demonstrated (no effect ).

- Efficacité antirides du mélange 1/1 d'un extrait de macrocystis pyrifera et d'un extrait de tétraselmis suecica : 31,1 % de réduction du volume des rides et 100 % des volontaires montrant un effet favorable (test réalisée sur 11 femmes après 4 semaines d'utilisation).  - Anti-wrinkle efficacy of the 1/1 mixture of an extract of macrocystis pyrifera and a tetraselmis suecica extract: 31.1% reduction in the volume of wrinkles and 100% of volunteers showing a favorable effect (test carried out on 11 women after 4 weeks of use).

Ainsi, l'invention se rapporte aussi à un procédé cosmétique pour le soin du visage et du corps et notamment pour l'amélioration du relief et du micro-relief cutanés et tout particulièrement pour diminuer la profondeur des rides, consistant à appliquer sur la peau une composition comme décrite précédemment.  Thus, the invention also relates to a cosmetic process for the care of the face and body and in particular for the improvement of the skin relief and micro-relief and particularly to reduce the depth of wrinkles, consisting in applying to the skin a composition as described above.

Une composition cosmétique selon l'invention peut se présenter sous diverses formes cosmétiques appropriées, comme de façon non limitative une émulsion (crème, lait), une lotion, un gel, un masque, etc.  A cosmetic composition according to the invention may be in various appropriate cosmetic forms, such as but not limited to an emulsion (cream, milk), a lotion, a gel, a mask, etc.
