Definitions
- the present invention relates to a cosmetic composition or
- dermatological comprising a plant extract, to a device comprising this cosmetic or dermatological composition, as well as to a non-therapeutic cosmetic care process, comprising the application to the skin or the mucous membranes of the cosmetic composition and to a use of the plant extract as a cosmetic active.
- cosmetics and dermatology more particularly skin cosmetics.
- the skin is a vital organ in its own right which consists of three tissues
- multistratified (Malpighian) and keratinized epithelium is composed of different cells associated with numerous barrier and protective functions.
- the majority cells are the keratinocytes which divide in the basal layer and begin their differentiation up to the horny layer (outermost layer) then are eliminated by desquamation, in 21 to 28 days, on average.
- the epidermis also contains melanocytes, cells responsible for the pigmentation of the skin. The latter present dendrites, branching allowing the transport of melanin to the surrounding keratinocytes.
- a melanocyte is in contact with about forty keratinocytes on average, which forms a pigment unit.
- the major role of the epidermis is to provide the skin, and therefore the human body, with a first line of protection against external attacks, such as physical, chemical, water and bacteriological attacks.
- This protection is provided in particular by the most differentiated layers and the horny layer known for its hydrophobic properties, its compact and waterproof appearance.
- Good keratinocyte differentiation and therefore good desquamation are essential for a smooth, homogeneous and regular surface.
- external stresses and age slow down this process which can then become longer and more irregular.
- As the desquamation becomes irregular and / or anarchic defects in the smoothness and homogeneity of the surface of the skin set in.
- pigment spots can appear due to the disorganization of melanin, which involves irregularities in the color and complexion of the face.
- fibroblasts and matrix proteins giving the skin its known qualities of compressibility and elasticity. Changes in its texture and composition are largely responsible for the changes in the skin that occur during aging. The relief of the stratum corneum is, moreover, directly conditioned by the quality and density of the underlying dermis.
- structures such as an important circulatory and nutritive network, made up of blood vessels and lymphatic capillaries, as well as the epidermal appendages: hair, body hair, nails, pilosebaceous glands and sweat glands, which originate in the deep dermis.
- the hypodermis located in depth and consisting mainly of fatty lobules (adipocytes), provides a primary support function, mechanical and thermal protection and also plays a role of storing energy reserves that can be quickly mobilized for all needs. biological, such as cell renewal, body defense or muscle contraction.
- adipocytes fatty lobules
- biological such as cell renewal, body defense or muscle contraction.
- Expectations in terms of cosmetics are moving more and more towards natural, effective and eco-designed products. Cosmetic responses to the problem of skin aging are frequently oriented towards alpha-hydroxy acids (glycolic, malic, citric and tartaric acid) which present an immediate action due to the exfoliating effect. But they can lead to
- the object of the present invention is precisely to meet these needs and drawbacks of the prior art.
- the inventors are the very first to use a vegetable gold extract
- the inventors have in particular demonstrated an effect of this extract on the differentiation of epidermal keratinocytes, the inhibition of melanin synthesis, the stimulation of the transfer of melanin from the melanocytes to the surrounding keratinocytes, but also a effect on angiogenesis.
- this extract makes it possible to improve and protect the appearance of the skin, in particular by providing an effect of smoothing and / or softness and / or of shine enhancement, moisturizing effect and nourishing effect.
- this extract also makes it possible to standardize the complexion and to limit the pigmented spots of the skin, in particular by inhibiting the synthesis of melanin, the homogenization of the transfer of melanin into the keratinocytes, in order to obtain a better distribution of the coloration.
- a first object of the invention relates to a composition
- cosmetic or dermatological comprising at least one plant gold extract (Syngonanthus nitens Ruhland) and at least one cosmetically and / or dermatologically acceptable vehicle.
- plant gold extract Syngonanthus nitens Ruhland
- Syngonanthus nitens Ruhland also called Eriocaulon nitens Bong., Golden grass in English, Capim dourado in Portuguese, commonly called “vegetable gold” in French or also golden grass, is a herbaceous endemic to Brazil. It grows in the humid regions (marshes) of Jalapâo in the east of the state of Tocantins.
- the Jalopâo is part of the Cerrado, a precious Brazilian ecosystem in which we find more than 11,000 plant species and 3 biotypes.
- Syngonanthus nitens is a perennial polycarpic herb with leaves arranged in a spiral in a basal rosette of 4cm in diameter.
- the plant can produce 1 to 10 stems annually, each stem having a flower head at the top. Flowering begins in July and seeds are produced from September to October. Each flower head contains approximately 60 +/- 14 seeds measuring 0.7 to 1.0mm long and 0.2 to 0.35mm wide. The seeds are dispersed naturally by wind or human hand, allowing their reproduction.
- the stem is covered with a basal sheath. Between September and October, the stems take on a golden color and easily detach from the basal rosette. The stem measures between 30 and 70cm long and 5mm wide, depending on the variety.
- Vegetable gold grows near waterways, especially marshes. In this region, the flowering stalk is harvested for local crafts, especially to make jewelry or bags. The harvest of vegetable gold takes place exclusively from September 20 to November 20 and flowering stems after harvest must be tapped to disseminate the seeds in nature.
- the methanolic extract of the stems also exhibits antioxidant and antimicrobial efficacy (Felipe Hilârio: “Estudo quimico e avaliacao da atividade antioxidante e antimicrobiana dos escapos of Syngonanthus nitens (Bong.) Ruhland. (Eriocaulacea)”. 2012 ([2])) .
- At least one plant gold extract can be an extract of all or part of the aerial parts of the plant. It can in particular be chosen from an extract of flowering tops, a stem extract, an extract of a stem sheath, or a mixture thereof.
- the extract can be an extract from the stems and sheaths of the plant.
- the rods and sheaths can, for example, be made from co-products of local crafts.
- the plant gold extract used in the invention can be an alcoholic, aqueous or hydro-alcoholic extract of the parts of plants defined above.
- the composition can comprise all or part of the compounds
- hydrophilic and water-soluble which are present in the plant, in particular in the stems and sheaths of the plant, and which are extracted therefrom by means of a solvent chosen from water, or an alcohol or a mixture of several alcohols, or a mixture of water and at least one alcohol.
- the extract can be a hydro-alcoholic, in particular hydroethanolic, extract of stems, in particular comprising the residues of golden stems and the residues of the sheaths of the stems.
- the extraction solvent used to prepare the extract used in the context of the present invention can be chosen from solvents known to those skilled in the art, such as for example ethanol, propylene glycol, butylene glycol , dipropylene glycol, methylpropanediol, propane-1, 3-diol, glycerin, water or a mixture of these solvents. It may, for example, be an extract obtained from stems, in particular extracted with a hydroethanolic mixture.
- the vegetable gold extract can be obtained by extraction hydroalcoholic, preferably in a water / ethanol mixture having a water / alcohol mass ratio of between 90/10 and 10/90, for example of the order of 70/30.
- the vegetable gold extract can be obtained by any process known to those skilled in the art.
- the vegetable gold extract can be obtained by grinding (or not) one or more parts of the plant, preferably dried and cut beforehand, then by bringing the ground material into contact with a solvent as defined above, preferably a water / alcohol mixture having a water / alcohol ratio between 90/10 and 10/90, for example a water / alcohol mixture having a weight ratio of 70/30.
- the extraction can be carried out by mixing the ground material and the solvent and by subjecting this mixture to stirring so as to optimize the exchanges between the ground material and the extraction solvent.
- the extraction can be carried out at a temperature of 20 to 100 ° C.
- the extraction can be carried out for a period of the order of 1/2 to 4 hours.
- the amount of plant used relative to the solvent can be for example from 0.5 to 20% by weight relative to the total weight of plants and solvent, for example 1.0 to 15.0%, 2.0 to 15, 0%, or 3.0 to 12.0% or 4.0 to 6.0%, for example about 5.0%.
- the extract used in the present invention can optionally be purified prior to its use in the composition. This purification can for example be carried out by liquid-liquid extraction, by precipitation or by preparative chromatography.
- the extract used in the present invention can be diluted in a solvent known to those skilled in the art, such as, for example, propylene glycol, butylene glycol, dipropylene glycol, methylpropanediol, propane-1, 3-diol, glycerin, water or a mixture of these solvents.
