Description

Use of vanillin 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 to compositions comprising one or more UV-A and / or UV-B screening agents.

[0002] The cosmetic field to which the application of the composition, and also the use, targeted 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 common practice 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, conveyed 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.Disclosure of the invention

[0008] In the light of the foregoing, it is thus clear that there remains 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.

[0009] The need thus remains 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.

[0010] 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, notably in terms of odour, under the effects of light and temperature, regardless of the presentation form of the composition.Summary of the invention

[0011] One object of the present invention is most particularly to provide compounds that are most particularly effective in masking the unpleasant odour of UV-A and / or UV-B screening agents, notably organic UV-A and / or UV-B screening agents.

[0012] Thus, according to a first aspect, the present invention relates to the use of:

[0013] i) one or more compounds of formula(I)as defined below, and also the optical isomers thereof, the organic or mineral acid or base salts thereof, or a solvate thereof such as hydrates, for inhibiting and / or attenuating and / or masking the odour ii) of one or more organic UV-A and / or UV-B screening agents;

[0014]

[0015] in which formula(I):

[0016] R1represents a hydrogen atom or a (C1-C6)alkyl group, preferably a (C1-C4)alkyl group such as methyl or ethyl, more preferentially ethyl;

[0017] - R2represents i) a hydrogen atom or a group chosen from ii) (C1-C6)alkyl and iii) (C1-C6)alkoxy, preferably a hydrogen atom;

[0018] R3,R4andR5, which may be identical or different, preferably identical, represent a hydrogen atom or a group chosen from a) hydroxyl, b) amino, c) (C1-C4)alkyl, and d) (C1-C4)alkoxy; more preferentially,R3,R4andR5represent a hydrogen atom.

[0019] The uses under consideration according to the invention are cosmetic and non-therapeutic.

[0020] The present invention also relates to a composition, notably a cosmetic composition, comprising:

[0021] i) one or more compounds of formula(I)as defined previously, and

[0022] ii) one or more organic UV-A and / or UV-B screening agents, and

[0023] iii) optionally one or more inorganic UV-screening agents,

[0024] it being understood that:

[0025] - the total amount of compound(s) of formula(I)as defined previously is less than or equal to 1%, more preferentially less than or equal to 0.5% and more particularly less than or equal to 0.2% by weight relative to the total weight of the composition; and

[0026] - when the amount of compound(s)(I)is between 0.0001% and 0.0003%, then the composition cannot comprise 2-ethylhexyl para-methoxycinnamate (also called 2-ethylhexyl 4-methoxycinnamate, ethylhexyl methoxycinnamate or Parsol MCX 5466-77-3) in an amount of between 7% and 8% by weight relative to the total weight of the composition;

[0027] - and when the composition comprises ethanol, the amount is not greater than 50% by weight relative to the total weight of the composition.

[0028] Preferentially, the composition comprises one or more compounds of formula(I)as defined previously in an amount of between 0.001% and 0.5%, more particularly between 0.01% and 0.08% and better still between 0.02% and 0.05% such as 0.025% ± 0.002% by weight relative to the total weight of the composition.

[0029] According to one embodiment of the invention, the composition does not comprise any 2-ethylhexyl para-methoxycinnamate.

[0030] Japanese patent application JP 2022116132 describes fruit-flavoured drinks comprising esters, alcohols, aldehydes, acetals, ketones, phenols, ethers, lactones and other nitrogenous and / or sulfurous hydrocarbon-based compounds, of which ethylvanillin is mentioned.

[0031] A South Korean patent KR 10-0871911 describes antisun compositions comprising a vanilla extract and a chicory root extract for preventing skin erythema or treating atopic dermatitis.

[0032] Vanillin derivatives are known and used in cosmetics, particularly in the field of fragrances. Mention may be made of compositions and emulsions fragranced with ethylvanillin (see, for example, US 2016 / 015 613, EP 2 918 260 A1 and EP 2 782 546 A1). These compositions do not comprise any UV-screening agents.

[0033] Suncare emulsions are described which include particular zinc oxide powders mixed with fragrancing formulations comprising a complex mixture of ingredients known in perfumery, including vanillin and ethylvanillin (EP 2 497 457). These zinc oxide-based compositions are said to have a pleasant feel on application and to be transparent. Mention is also made of oil-in-water emulsions comprising more than 50% ethanol, sunscreens combined with other ingredients including a complex mixture of fragrances containing ethylvanillin, and BHT (EP 2 782 546).

[0034] However, as emerges from the examples hereinbelow, the compound(s) of formula(I)or(II)as defined hereinbelow 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, while maintaining the ability of the screening agents containing the composition to screen out UV rays.Definitions

[0035] In the context of the present invention, and unless otherwise indicated, the following definitions apply:

[0036] The term “(C1-C6)(alkyl)vanillin” means vanillin, i.e. 3-methoxy-4-hydroxybenzaldehyde and derivatives thereof including a (C2-C6)alkyl group in place of the methyl of the methoxy in position 3 of the 4-hydroxybenzaldehyde.

[0037] The compounds of formula(I)or(II), the organic or mineral base salts thereof, or the solvates thereof such as hydrates, may be of natural or synthetic origin, preferably of natural origin.

[0038] According to one embodiment of the invention, the compound(s) of formula(I), the organic or mineral base salts thereof, or the solvates thereof such as hydrates, are in the form of organic or mineral base salts, such as alkali metal salts (Na+, K+), alkaline-earth metal salts (Mg2+, Ca2+) and ammonium ions. They may be of natural or synthetic origin.

[0039] The term “to inhibit” means to reduce, totally or partially, the aspect under consideration, for example the unpleasant odour of UV-A and / or UV-B screening agents.

[0040] The term “to attenuate” means to reduce the intensity of the aspect under consideration, for example the unpleasant odour of UV-A and / or UV-B screening agents.

[0041] The term “to mask” means to cover the aspect under consideration totally or partially, for example the unpleasant odour of UV-A and / or UV-B screening agents.

[0042] For the purposes of the present invention, the term “fragranced composition” or “fragrancing composition” is intended to denote any composition which leaves a fragrance or odour on keratin materials after application. A fragrance is the result of a combination of different odorous substances which each provide a specific diffusing odour or “note” and which respectively evaporate at different periods. More specifically, each fragrance has what is known as a “top note”, which is the odour which diffuses first when the fragrance is applied or when the receptacle containing it is opened, a “middle or heart note”, which corresponds to the full fragrance (given off for a few hours after the “top note”) and a “base note”, which is the most persistent odour (given off for several hours after the “middle note”). The persistence of the base note corresponds to the durability of the fragrance.

[0043] For the purposes of the present invention, the term “fragrancing substance” is understood to denote any fragrance, odorous starting material or aroma which is capable of giving off a pleasant odour, in particular as defined in the continuation of the text. For the purposes of the present invention, “fragrancing”, “odorous” or “odoriferous” substances are synonymous.

[0045] The expressions “between ... and ...”, “comprises from … to ...”, “formed from … to ...” and “ranging from ... to ...” are equivalent and are intended to mean that the limits are included, unless otherwise indicated.

[0046] The expression “at least one” is equivalent to “one or more”.

[0047] In the description and the examples, unless otherwise indicated, the percentages are percentages by weight (i.e. percentages by mass). The percentages are thus expressed by weight relative to the total weight of the composition. The temperature is expressed in degrees Celsius, unless otherwise indicated, and the pressure is atmospheric pressure, unless otherwise indicated.

[0048] A composition according to the invention is generally suitable for application to keratin materials, notably to the skin and / or the lips, and thus generally comprises a physiologically acceptable medium, i.e. a medium that is compatible with the skin and / or the lips. It is preferably a cosmetically acceptable medium, i.e. a medium which has a pleasant colour, odour and feel and which does not cause any unacceptable discomfort, i.e. stinging, tautness or redness, liable to discourage the user from applying this composition.

[0049] For the purposes of the present invention, the term “optical isomer” is intended to denote enantiomers, which are configurational isomers which are mirror images of each other and which are not superposable. In particular, they may be conformational stereoisomers, i.e. compounds which differ in their rotation around a single bond, or configurational stereoisomers, in particular enantiomers or diastereoisomers.

[0050] For the purposes of the present invention, the term “solvate” is intended to denote the form of the compound when it is associated with a solvent. The solvates include conventional solvates formed during the process of preparation of the compound. Examples of solvates are those obtained in the presence of water or of a linear or branched alcohol, in particular ethanol or isopropanol.

[0051] For the purposes of the present invention, the term “hydrate” is intended to denote the form of the compound when it is associated with water.

[0052] The term “alkyl” means a linear or branched, saturated hydrocarbon-based group. A group (Cx-Cz)alkyl represents a linear or branched hydrocarbon-based chain comprising from x to z carbon atoms, in particular from C1-C12, more particularly C1-C10, preferably C1-C6, even more preferentially C1-C4, such as methyl, ethyl, propyl, i-propyl, n-butyl, i-butyl or t-butyl.

[0053] The term “alkoxy” means an “alkoxy” or alkyl-oxy or alkyl-O- group with alkyl as defined previously. A (Cx-Cz)alkoxy group represents a radical -O-(Cx-Cz)alkyl in which the (Cx-Cz)alkyl group is as defined previously.

[0054] For the purposes of the present invention, the term “UV-screening agent” is intended to denote any compound which screens out ultraviolet (UV) radiation in the wavelength range extending from 280 nm to 400 nm.

[0055] The term “UV-B screening agent” is understood to denote any compound which screens out (or absorbs) ultraviolet (UV) radiation in the wavelength range extending from 280 nm to 320 nm.

[0056] The term “UV-A screening agent” is understood to denote any compound which screens out (or absorbs) ultraviolet (UV) radiation in the wavelength range extending from 320 nm to 400 nm. A distinction may be made between short UV-A screening agents (which absorb rays at a wavelength of between 320 and 340 nm) and long UV-A screening agents (which absorb rays at a wavelength of between 340 and 400 nm).

[0059] The term “hydrophilic UV screening agent” means any organic or inorganic cosmetic or dermatological compound which screens out UV radiation, which is liable to be fully dissolved in molecular form in a liquid aqueous phase or else which can be solubilized in colloidal form (for example in micellar form) in a liquid aqueous phase.

[0060] The term “hydrophobic UV-screening agent” means any cosmetic or dermatological screening agent that can be fully dissolved in molecular form in a liquid fatty phase or that can be dissolved in colloidal form (for example in micellar form) in a liquid fatty phase.

[0061] For the purposes of the invention, the term “fatty phase” means a phase comprising at least one oil and all of the liposoluble and lipophilic ingredients or fatty substances required according to the invention.

[0062] The term “oil” means a water-immiscible non-aqueous compound that is liquid at room temperature (20°C) and at atmospheric pressure (760 mmHg).

[0063] For the purposes of the present invention, the term “hydrocarbon-based oil” means an oil mainly containing hydrogen and carbon atoms.

[0064] The term “silicone oil” means an oil comprising at least one silicon atom and notably at least one Si-O group.

[0065] The term “fluoro oil” means an oil comprising at least one fluorine atom.

[0066] For the purposes of the invention, the term “volatile oil” means any oil that is capable of evaporating on contact with the skin in less than one hour, at room temperature and atmospheric pressure. The volatile oil is a volatile cosmetic compound, which is liquid at room temperature, notably having a non-zero vapour pressure, at room temperature and atmospheric pressure, notably having a vapour pressure ranging from 0.13 Pa to 40 000 Pa (10-3to 300 mmHg), in particular ranging from 1.3 Pa to 13 000 Pa (0.01 to 100 mmHg) and more particularly ranging from 1.3 Pa to 1300 Pa (0.01 to 10 mmHg). The term “non-volatile” refers to an oil whose vapour pressure at room temperature and atmospheric pressure is non-zero and is less than 10-3mmHg (0.13 Pa).

[0067] In the present invention, the term “water-soluble solvent” denotes a compound that is liquid at room temperature and water-miscible (miscibility with water of greater than 50% by weight at 25°C and atmospheric pressure).

[0071] The term “filler” should be understood as meaning colourless or white solid particles of any shape which are provided in an insoluble form and dispersed in the medium of the composition. These fillers, of mineral or organic nature, give body or rigidity to the composition and / or softness and uniformity to the application. They are different from dyestuffs.

[0072] Other characteristic, variants and advantages of the invention will become more clearly apparent on reading the description and examples that follow, which are given as non-limiting illustrations of the invention.Detailed description

[0309] 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.

[0310] 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.

[0311] As is known, silicones are organosilicon polymers or oligomers of linear or cyclic, branched or crosslinked structure, of variable molecular weight, 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-based radicals being directly attached via a carbon atom to said silicon atoms.

[0312] The term “silicones” also encompasses the silanes required for their preparation, in particular alkylsilanes.

[0357] A composition according to the invention may comprise one or more fragrancing substances distinct from the compound(s) of formula (I).

[0358] In particular, a composition according to the invention may comprise at least 0.01% by weight of fragrancing substance(s) different from the compound(s) of formula (I), in particular at least 0.5% by weight, in particular not more than 1% by weight, relative to the total weight of the composition.

[0359] 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) distinct from the compounds of formula (I), relative to the total weight of the composition.

[0360] 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.

[0361] 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.

[0362] 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.

[0363] 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, generally of complex composition, obtained from a botanically defined plant raw material, either by steam distillation, or by dry distillation, or by an appropriate 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.

[0364] 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 conditions the characteristics of the essential oil, in particular viscosity, colour, solubility, volatility, and richness or poorness in certain constituents.

[0365] 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 “floral distilled water”.

[0366] 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.

[0367] 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.

[0368] Essential oils are generally volatile and liquid at room temperature, which distinguishes them from “set” 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.

[0369] 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.

[0550] The composition according to the invention (formula 4) has a significantly reduced smell cuing more pleasant odor, contrary to the comparative composition (CF). Indeed, ethyl vanillin has a profile with a less 'chemical' scent and significantly higher score on “just right intensity” on skin on users.

[0551] This phenomenon is observed after the composition has been stored even several months after at room temperature.

[0552] “Idem” implies that the quantity of the compounds in Comparative Formula (CF) is exactly the same as Formula 4 for each ingredient. Thus, it appears from the table 5 above that the distinctive characteristic, namely the presence of ethyl vanillin, even at a very low concentration, significantly improves the overall scent of the composition, including UV filters, even in high quantities.
