Description

Use of zingerone derivatives for inhibiting, attenuating and / or masking the odour of organic UV screening agents, and compositions containing same

[0001] The present invention relates to the field of cosmetic products, and is notably directed towards proposing the non-therapeutic cosmetic use of at least one compound of formula(I)as defined hereinbelow as a masking agent and / or as an inhibitor of the odour of organic UV-A and / or UV-B screening agent(s), and also compositions comprising one or more UV-A and / or UV-B screening agent(s).

[0002] The cosmetic field to which the application of the composition, and also the use, referred to by the present invention may extend is notably the field of makeup and / or care and / or hygiene of keratin materials, the field of sun protection, the field of hair, or also the field of fragrances.Prior art

[0003] It is customary to introduce UV-A and / or UV-B screening agents, in particular organic UV-A and / or UV-B screening agents, into cosmetic compositions.

[0004] Such compounds may be intended to provide sun protection. They may also be useful as stabilizers, which have the role of keeping the organoleptic properties of products stable under various stresses, such as UV-A and / or UV-B rays and thermal shocks, notably in fragrancing compositions.

[0005] Thus, a wide variety of cosmetic compositions may contain a combination of several organic and / or inorganic UV-A and / or UV-B screening agents, carried in an oil phase and / or an aqueous phase, and offered in various presentation forms.

[0006] However, UV-A and / or UV-B screening agents are not entirely satisfactory, for example for fragile fragrances rich in natural substances.

[0007] Specifically, the presence of UV-A and / or UV-B screening agents in compositions may have cosmetic drawbacks, and in particular may generate a particularly unpleasant odour which is a real nuisance for users, which may limit their use in cosmetic compositions.

[0008] EP 2 485 708 describes a sun protection composition comprising at least one 2-alkoxy-4-alkyl ketone phenol including ethylzingerone and at least one UV screening agent.

[0009] Therefore, to our knowledge, the compounds of formula(I)as defined above and below have never been used to attenuate the odour of UV screening agents, notably organic UV-A and / or UV-B screening agents.

[0010] However, against all expectations and as can be seen from the examples hereinbelow, the compound(s) of formula (I) have been characterized as odour neutralizers for the odour of UV screening agents, notably organic UV-A and / or UV-B screening agents, and thus as being capable of attenuating and / or inhibiting and / or masking the unpleasant odour of UV-A and / or UV-B screening agents.Disclosure of the invention

[0011] In the light of the foregoing, it is thus clear that there is a need for consumers to have cosmetic and / or dermatological compositions comprising organic UV-A and / or UV-B screening agents, which have an odour that is pleasant to users, while also having advantageous cosmetic performance qualities.

[0012] There is thus the need for compounds that mask and / or inhibit and / or attenuate the unpleasant odour of UV-A and / or UV-B screening agents, particularly in cosmetic compositions.

[0013] There is also a need for compositions, in particular cosmetic compositions, comprising one or more organic UV-A and / or UV-B screening agents, which remain stable and homogeneous over time, particularly in terms of odour, under the effects of light and temperature, regardless of the presentation form of the composition.Summary of the invention

[0014] The present invention relates to the field of cosmetic products, and is notably directed towards proposing the non-therapeutic cosmetic use of at least one compound of formula(I)as defined hereinbelow as a masking agent and / or as an inhibitor of the odour of organic UV-A and / or UV-B screening agent(s), and also compositions comprising one or more UV-A and / or UV-B screening agent(s).

[0311] The use and / or the composition according to the invention may also involve one or more inorganic (or mineral) UV screening agent(s). The pigments may or may not be coated.

[0312] The coated pigments are pigments which have undergone one or more surface treatments of chemical, electronic, mechanochemical and / or mechanical nature with compounds as described, for example, in Cosmetics & Toiletries, February 1990, Vol. 105, pages 53-64, such as amino acids, beeswax, fatty acids, fatty alcohols, anionic surfactants, lecithins, sodium, potassium, zinc, iron or aluminium salts of fatty acids, metal alkoxides (titanium or aluminium alkoxides), polyethylene, silicones, proteins (collagen, elastin), alkanolamines, silicon oxides, metal oxides or sodium hexametaphosphate.

[0313] As is known, silicones are organosilicon polymers or oligomers having a linear or cyclic, branched or crosslinked, structure, of variable molecular weight, which are obtained by polymerization and / or polycondensation of suitably functionalized silanes, and consist essentially of a repetition of main units in which the silicon atoms are linked together via oxygen atoms (siloxane bond), optionally substituted hydrocarbon radicals being directly bonded via a carbon atom to said silicon atoms.

[0314] The term “silicones” also encompasses the silanes required for their preparation, in particular alkylsilanes.

[0356] According to another particular embodiment, the use and / or the composition according to the invention comprises iii) one or more inorganic UV screening agents.

[0357] According to a particular embodiment, the amount iii) of the inorganic UV screening agent(s) may range from 0.01% to 30% by weight relative to the total weight of the composition. It ranges for example from 0.05% to 20% by weight, particularly from 0.1% to 10% by weight, relative to the total weight of the composition.

[0359] According to one embodiment of the invention, the composition also comprises one or more fragrancing substances.

[0360] In particular, a composition according to the invention may comprise at least 0.01% by weight of fragrancing substance(s), in particular at least 0.5% by weight, in particular not more than 1% by weight, relative to the total weight of the composition.

[0361] According to a particular embodiment of the invention, the composition according to the invention comprises less than 5% by weight, in particular less than 3% by weight, more particularly less than 1% by weight, even more particularly less than 0.5% by weight, or is even free from fragrancing substance(s), relative to the total weight of the composition.

[0362] Fragrancing substances are compositions notably containing the starting materials described in S. Arctander, Perfume and Flavor Chemicals (Montclair, N.J., 1969), in S. Arctander, Perfume and Flavor Materials of Natural Origin (Elizabeth, N.J., 1960) and inFlavor and Fragrance Materials – 1991, Allured Publishing Co., Wheaton, III.

[0363] A composition according to the invention may notably comprise at least one fragrancing substance chosen from essential oils, perfumes and aromas of synthetic or natural origin, and mixtures thereof.

[0364] They may be natural products, such as essential oils, absolutes, resinoids, resins, concretes, and / or synthetic products, such as terpene or sesquiterpene hydrocarbons, alcohols, phenols, aldehydes, ketones, ethers, acids, esters, nitriles or peroxides, which may be saturated or unsaturated, and aliphatic or cyclic.

[0365] According to the definition given in the international standard ISO 9235 and adopted by the Commission of the European Pharmacopoeia, an essential oil is an odorous product, usually of complex composition, obtained from a botanically defined plant raw material by steam distillation, dry distillation, or a suitable mechanical process without heating (cold pressing). The essential oil is usually separated from the aqueous phase via a physical process that does not result in any significant change in the composition.

[0366] The choice of the method for obtaining essential oils depends mainly on the starting material: its original state and its characteristics, its intrinsic nature. The “essential oil / plant starting material” yield may be extremely variable depending on the plant: 15 ppm to more than 20%. This choice determines the characteristics of the essential oil, in particular viscosity, colour, solubility, volatility, and richness or poorness in certain constituents.

[0367] Steam distillation corresponds to vaporization, in the presence of steam, of a substance with low water miscibility. The raw material is placed in contact with boiling water or steam in an alambic. The steam entrains the essential oil vapour, which is condensed in the condenser so as to be recovered as a liquid phase in a Florentine vase (or essence jar), where the essential oil is separated from the water by settling. The aqueous distillate that remains after the steam distillation, once the separation of the essential oil has been performed, is known as the “aromatic water” or “hydrolate” or “distilled floral water”.

[0368] Production by dry distillation consists in obtaining the essential oil by distillation of woods, barks or roots, without addition of water or steam, in a closed chamber designed so that the liquid is recovered at the bottom. Cade oil is the best known example of a product obtained in this way.

[0369] The method of production by cold pressing applies only to citrus fruits (Citrus spp.) via mechanical processes at room temperature. The principle of the method is as follows: the zests are torn into pieces and the contents of the secretory sacs that have been broken are recovered by a physical process. The conventional process consists in exerting an abrasive action on the entire surface of the fruit under a stream of water. After removal of the solid waste, the essential oil is separated from the aqueous phase by centrifugation. The majority of industrial installations allow simultaneous or sequential recovery of the fruit juices and of the essential oil.

[0370] Essential oils are generally volatile and liquid at room temperature, which differentiates them from “fixed” oils. They are more or less coloured and their density is generally less than that of water. They have a high refractive index and most of them deflect polarized light. They are liposoluble and soluble in the usual organic solvents, distillable with steam, and very sparingly soluble in water.

[0371] Among the essential oils that may be used according to the invention, mention may be made of those obtained from plants belonging to the following botanical families: Abietaceae or Pinaceae, for example conifers; Amaryllidaceae; Anacardiaceae; Anonaceae, for example ylang ylang; Apiaceae, for example Umbelliferae, in particular dill, angelica, coriander, sea fennel, carrot or parsley; Araceae; Aristolochiaceae; Asteraceae, for example yarrow, artemisia, camomile, helichrysum; Betulaceae; Brassicaceae; Burseraceae, for example frankincense; Caryophyllaceae; Canellaceae; Cesalpiniaceae, for example copaifera (copaiba balsam); Chenopodaceae; Cistaceae, for example rock rose; Cyperaceae; Dipterocarpaceae; Ericaceae, for example gaultheria (wintergreen); Euphorbiaceae; Fabaceae; Geraniaceae, for example geranium; Guttiferae; Hamamelidaceae; Hernandiaceae; Hypericaceae, for example St John’s wort; Iridaceae; Juglandaceae; Lamiaceae, for example thyme, oregano, monarda, savory, basil, marjorams, mints, patchouli, lavenders, sages, catnip, rosemary, hyssop, balm, rosemary; Lauraceae, for example ravensara, sweet bay, rosewood, cinnamon, litsea; Liliaceae, for example garlic; Magnoliaceae, for example magnolia; Malvaceae; Meliaceae; Monimiaceae; Moraceae, for example hemp or hop; Myricaceae; Myristicaceae, for example nutmeg; Myrtaceae, for example eucalyptus, tea tree, paperbark tree, cajuput, backhousia, clove, myrtle; Oleaceae; Piperaceae, for example pepper; Pittosporaceae; Poaceae, for example citronella, lemongrass, vetiver; Polygonaceae; Renonculaceae; Rosaceae, for example roses; Rubiaceae; Rutaceae: all citrus plants; Salicaceae; Santalaceae, for example sandalwood; Saxifragaceae; Schisandraceae; Styracaceae, for example benzoin; Thymelaceae, for example agarwood; Tilliaceae; Valerianaceae, for example valerian, spikenard; Verbenaceae, for example lantana, verbena; Violaceae; Zingiberaceae, for example galangal, turmeric, cardamom, ginger; Zygophyllaceae.
