Definitions
- the present invention relates to the cosmetic use of a combination of immortelle extracts, namely an essential oil of immortelle and a subcritical water extract of immortelle spent grains, to reduce the visibility of skin pores and/or or tighten skin pores.
- Pores are small openings on the surface of the skin, whose physiological role is to allow the excretion of sweat and sebum.
- the sebaceous glands are located in the dermis, which is a connective tissue composed of an extracellular matrix (ECM) containing fibrous proteins (collagen, elastin), glycosaminoglycans and proteoglycans, and cells such as fibroblasts.
- ECM extracellular matrix
- fibrous proteins collagen, elastin
- glycosaminoglycans and proteoglycans and cells such as fibroblasts.
- the excretory duct of the sebaceous glands reaches the surface of the epidermis.
- the dermis and epidermis are separated from each other by a basement membrane which constitutes the dermo-epidermal junction.
- the latter is a complex structure of which type IV collagen is a majority constituent.
- type I collagen which is the majority constituent of the ECM, leads to a degradation of the latter which plays its supporting role less well, which leads to a deformation of the excretory ducts and therefore to a pore dilation. Furthermore, the decrease with age in the level of collagen IV leads to an alteration of the basement membrane which tends to flatten, and induces an enlargement of the pores which become more visible.
- the dilation of pores can also have causes other than skin aging and in particular have the origin of unsuitable hygiene, climatic or ethnic factors or excess sebum.
- the pores are more dilated on the face and in particular in the T zone (forehead, nose, chin), particularly in the nose area, and can be accentuated. by an increase in the width of the conical portion around the pore and/or a state of parakeratosis of the stratum comeum at the level of this conical portion, itself sometimes linked to excessive secretion of sebum and unsaturated fatty acids.
- camouflage techniques have already been proposed, such as for example the use of makeup compositions which may contain inorganic powders or polymers.
- these compositions tend to clog pores, thus generating other imperfections such as blackheads.
- astringent lotions to the skin which may contain aluminum salts, hydroalcoholic solutions, combinations of retinoids and hydroxy carboxylic acids, or even parakeratosis inhibitors such as glycine derivatives.
- these substances are known to be irritating to the skin.
- compositions based on ingredients of natural origin effective for this purpose have already proposed compositions based on ingredients of natural origin effective for this purpose.
- document FR3003167 describes a cosmetic composition containing three different extracts of immortelle, including an essential oil and an aqueous extract, as well as myrtle essential oil. This composition is notably judged by a panel of users to be effective in reducing the appearance of pores.
- document CN 109010520 discloses an anti-acne composition having an astringent effect and containing numerous ingredients, including an essential oil of immortelle which is used to reduce scars due to its cell regeneration capacity.
- the object of the invention is precisely the cosmetic use of a combination of an essential oil of immortelle of the species Helichrysum italicum and an extract of spent grains of immortelle of the species Helichrysum italicum obtained by extraction of spent grains. with subcritical water, to reduce the visibility of skin pores and/or tighten skin pores.
- a cosmetic process for reducing the visibility of skin pores and/or tightening skin pores comprising topical application to the skin.
- a cosmetic composition containing the combination of an essential oil of immortelle of the species Helichrysum italicum and an extract of spent grains of immortelle of the species Helichrysum italicum obtained by extraction of spent grains with subcritical water.
- the present invention uses an immortelle essential oil and an extract of immortelle spent grains, both from the species Helichrysum italicum.
- essential oil is meant in this description the product of hydrodistillation or steam distillation of volatile organic compounds present in any part of the immortelle or the whole plant, and more particularly in its aerial parts such as its flowers or flowering tops (i.e. the flowers and a few centimeters of stems).
- the odorous molecules contained in the plant are released and mechanically entrained with the water vapor which is either formed by boiling the water to which the plant is added (conventional hydrodistillation), or formed by boiling the water contained in the plant (hydrodistillation by microwave, possibly under vacuum), or supplied by a boiler and circulated through the plant (entrainment with water vapor).
- the distillate is then decanted to separate the essential oil used according to the invention from the hydrosol (or floral water).
- the solid residue which constitutes the spent grains can be recovered and treated to prepare the immortelle spent grains extract also used in the present invention.
- the Helichrysum italicum essential oil of Corsican origin preferentially used according to the invention contains, as main constituent, neryl acetate, which generally represents at least 30% by weight of the total constituents of the essential oil, as measured by gas chromatography coupled with mass spectrometry analysis (GC-MS).
- Immortelle essential oil is combined, in this composition, with an extract of immortelle spent grains.
- diregs we mean the solid residue remaining after hydrodistillation or steam distillation of any part of the immortelle, preferably its flowering tops, and separation of the essential oil and the hydrosol produced.
- This extract of immortelle spent grains is characterized by the fact that it contains flavonol glycosides whose B ring is dihydroxylated.
- Flavonoids constitute a class of polyphenols containing the skeleton below.
- Flavonols constitute a category of flavonoids which precisely has the following structure:
- flavonols on the B ring such as baicalein
- mono-hydroxylated flavonols on the B ring such as kaempferol
- di-hydroxylated flavonols on the B ring such as quercetin and quercetagetin.
- the Applicant has demonstrated, by gas chromatography coupled with mass spectrometry, that the extract of immortelle spent grains according to the invention is characterized by the presence of flavonol heterosides whose B ring is dihydroxylated, which does not do not appear in other aqueous extracts, obtained in particular by using water at room pressure and temperature as the only extraction solvent.
- flavonol glycosides generally comprise at least one glycoside, in particular an O-hexoside, of quercetagenin, at least one quercetin glycoside, in particular a quercetin-O-hexoside-O-rhamnoside, or mixtures thereof.

- the volatile compounds of the spent grain extract according to the invention also contain less than 2%, generally less than 1%, of nerol.
- the immortelle spent grains extract can be obtained following a process comprising the subcritical water extraction of immortelle spent grains.
- This process is advantageously implemented in dynamic mode, by percolation of water in the subcritical state through the spent grains placed in an autoclave, generally of the tubular type.
- the spent grains can be found in dry or fresh form and may or may not be crushed. Dried and crushed spent grains are advantageously used.
- the flow rate Q can for example be between 1 and 4 ml/ml, preferably between 2 and 3 ml/min.
- the temperature and pressure of the water are chosen so as to maintain the water in the subcritical state, more particularly to maintain the water in the liquid state at a temperature above 100°C. It is thus possible to use an extraction temperature of between 120 and 175°C, preferably between 150 and 175°C, for example 150°C, and a pressure of 10 to 60 bars, preferably of 20 to 60 bars, for example around 30 bars. In any case, the water is kept below the critical point, corresponding to the temperature / pressure couple of 374°C / 220 bars. Beyond that, the water actually reaches the supercritical state. This process can for example be carried out for a total duration of 25 to 100 minutes.
