Description

Technical Field

[0001] The present invention is concerned with providing a novel fragrance-enhancing composition, in particular a cosmetic composition, for use in the field of fragrance enhancement of keratin materials and / or clothing, but also in the field of care and / or cosmetic treatment of keratin materials. Prior art

[0002] In general, the formulation of environmentally friendly cosmetic products is becoming a major challenge to meet new consumer expectations, in particular with regard to natural and / or eco-friendly products, that is to say products which are designed and developed with consideration for environmental impact.

[0003] It is more particularly desirable to make it possible to protect cosmetic preparations for the consumer, in particular while avoiding the use of compounds which may give rise to suspicion on the part of the consumer, for example those compounds which are suspected of being endocrine disruptors.

[0004] These environmental issues concern all cosmetic products, especially fragranced compositions.

[0005] It is known that fragrance is a combination of different odor-emitting substances that evaporate at different times. Each fragrance exhibits a so-called "top note" (which is the first odor diffused during the application of the fragrance or when the container containing the fragrance is opened), a "middle note or heart note" corresponding to the full fragrance (which is emitted several hours after the "top note"), and a "base note" which is the most persistent odor (which is emitted several hours after the "middle note"). The persistence of the base note corresponds to the retention time of the fragrance.

[0006] People have always tried to scent themselves and the objects around them or their environment, both to mask strong and / or unpleasant odors and to give a pleasant smell.

[0007] It is common practice to incorporate fragrances into a number of products or compositions, in particular cosmetic and dermatological compositions, such as eaux de parfums. ), eau de toilette, eau de parfum, aftershave or perfume (eaux de soin).

[0008] Flavors or aromatizing compositions must be stable, in particular olfactorily stable, and must have a pleasant smell, that is to say they must not deteriorate olfactorily over time. They must be resistant to various aggressive factors, such as light and temperature differences. In addition, there are great advantages in managing to stabilize the color of flavors or aromatizing compositions.

[0009] In order to ensure the stability of scented preparations, and in particular to prevent odour changes, it is known to incorporate antioxidant systems, such as BHT, therein.

[0010] However, BHT is a controversial compound as it is considered toxic to humans. In addition, it is suspected to be environmentally unfriendly and not biodegradable.

[0011] In fact, to the best of the inventors' knowledge, there is to date no substitute for BHT for use in flavoring aqueous / alcoholic products.

[0012] Finding alternative antioxidant systems to BHT has therefore been a major research line. Summary of the invention

[0013] There is thus still a need to find novel scented compositions, in particular aqueous / alcoholic compositions, which remain stable over time under the influence of light and temperature.

[0014] In particular, there remains a need for novel scented compositions, in particular aqueous / alcoholic compositions, which are olfactory stable over time and under the influence of light and temperature.

[0015] In particular, there remains a need to have available such scented cosmetic compositions the changes in their organoleptic properties, ie odour and / or colour, in particular at least colour, controlled over time.

[0016] There remains a particular need to have available scenting compositions which make it possible to maintain the olfactory effect over time without loss of intensity.

[0017] In particular, there is still a need for additives which make it possible to olfactorily stabilize most, indeed all, olfactory categories of fragrances.

[0018] There is also a need to improve the persistence of such perfumed compositions on keratin materials without degrading the perfume, particularly upon contact with other ingredients of the composition.

[0019] Furthermore, there is still a need to have available olfactory stable formulations which can comply with industrial constraints and which in particular can be easily manufactured.

[0020] Finally, there remains a need to have available flavoring compositions which are compatible with current consumer demands, particularly from an environmental point of view.

[0021] The present invention is particularly directed to meeting these needs. SUMMARY OF THE INVENTION

[0023] Thus, according to a first aspect of the present invention, the present invention relates to a scented composition, in particular a cosmetic composition, comprising:

[0024] a) at least one sulfur-containing antioxidant compound selected from the compounds of the following formula (I) and / or (II), and their optical and geometric isomers, salts and solvates, such as hydrates:

[0025] (I)R1-S-R2

[0026] (II)R1-SS-R2

[0027] Wherein formula (I) and (II):

[0028] R1 and R2, which are the same or different, represent a linear or branched (C1-C 24 ) alkyl group, linear or branched (C2-C 18 )alkenyl group, (C5-C 12 ) a cycloalkyl group, a phenylalkyl group having 7 to 15 carbon atoms or a phenyl group,

[0029] The alkyl groups and / or the alkenyl groups are optionally substituted by one or more groups selected from -OH, -OC(O)-R3, -C(O)-O-R3, -C(O)-R3, -OR'3 and -NH2 groups, in particular -OH, -OR'3 and -NH2 groups, and / or

[0157] c) Fragrance substances

[0158] As stated above, the composition according to the invention comprises at least one flavoring substance.

[0159] Fragrances are compositions containing, inter alia, starting materials described in S. Arctander, Perfume and Flavor Chemicals (Montclair, NJ, 1969), S. Arctander, Perfume and Flavor Materials of Natural Origin (Elizabeth, NJ, 1960), and Flavor and Fragrance Materials—1991, Allured Publishing Co., Wheaton, 111.

[0160] The scented composition according to the invention preferably comprises at least one scenting substance chosen from essential oils, essences and aromas of synthetic or natural origin, and mixtures thereof.

[0161] They may be natural products, such as essential oils, absolutes, extracts, resins, gels and / or synthetic products, such as terpenes or sesquiterpene hydrocarbons, alcohols, phenols, aldehydes, ketones, ethers, acids, esters, nitriles or peroxides, which may be saturated or unsaturated, aliphatic or cyclic.

[0162] According to the definition given by the international standard ISO 9235 and adopted by the European Pharmacopoeia Commission, essential oils are odoriferous products, usually of complex composition, obtained from botanically defined plant starting materials by steam distillation, or by dry distillation, or by appropriate mechanical processes without heating (cold pressing). Essential oils are usually separated from the aqueous phase by physical methods which do not result in any significant change in composition.

[0163] The choice of the method used to obtain the essential oil depends mainly on the starting material: its original state and its characteristics, its natural nature. The yield of "essential oil / plant starting material" is extremely variable, depending on the plant: 15 ppm to more than 20%. This choice determines the characteristics of the essential oil, in particular viscosity, color, solubility, volatility, and the richness or poverty of certain components.

[0164] Steam distillation corresponds to the evaporation of substances sparingly soluble in water in the presence of steam. The starting material is brought into contact with boiling water or steam in a distiller. The steam entrains the essential oil vapors, which are condensed in a condenser in order to be recovered as a liquid phase in a round-bottom flask (or perfume pot), in which the essential oils are separated from the water by sedimentation. The terms "aromatic water" or "hydrosol" or "distilled floral water" are used to describe the aqueous distillate remaining after steam distillation, once the essential oils have been separated.

[0165] Production by dry distillation consists in obtaining the essential oil by distilling the wood, bark or roots without adding water or steam in a closed chamber designed to recover the liquid at its bottom. Juniper oil is the best known example of this production method.

[0166] The cold pressing production method is applied exclusively to citrus fruits (Citrus) by mechanical processing at ambient temperature. The principle of this method is as follows: the peel is shredded and the contents of the secretory cavities that have been ruptured are recovered by physical methods. The traditional method consists in applying a grinding action over the entire surface of the fruit under a stream of water. After the solid waste has been removed, the essential oil is separated from the aqueous phase by centrifugation. In fact, most industrial plants allow the simultaneous or sequential recovery of juice and essential oil.

[0167] Essential oils are generally volatile and liquid at ambient temperature, which distinguishes them from "solidified" oils. They are more or less pigmented, and their density is generally lower than that of water. They have a high refractive index, and most turn polarized light. They are soluble in fats, and in standard organic solvents, can be steam distilled, and exhibit very low solubility in water.

[0168] Among the essential oils that can be used according to the invention, mention may be made of those obtained from plants belonging to the following plant families: Abietaceae or Pinaceae, for example conifers; Amaryllidaceae; Anacardiaceae; Annonaceae, for example Ylang-ylang; Apiaceae, for example umbellifers, in particular dill, angelica, coriander, sea fennel, carrot or parsley; Araceae; Aristolochiaceae; Asteraceae, for example Achillea, Artemisia, Chamomile, Helichrysum; Betulaceae; Cruciferae; Oleaceae, e.g. frankincense; Caryophyllaceae; Cinnamomum officinale, e.g. Copaiba; Chenopodiaceae; Helianthus annuus, e.g. Cistus; Cyperaceae; Dipterocarpon; Ericaceae, e.g. Gaultheria; Euphorbiaceae; Fabaceae; Geraniaceae, e.g. Pelargonium; Garciniaceae; Hamamelis; Nelumbo; Hypericaceae, e.g. St. John's wort; Iridaceae; Juglandaceae; Lamiaceae, e.g. Thyme, Oregano, Horse mint, Celery, Basil, Origanum vulgare, Mint, Patchouli incense, lavender, sage, camphor grass, rosemary, hyssop or balsam; Lauraceae, such as laurel, bay, dalbergia, cinnamon, litsea; Liliaceae, such as garlic; Magnoliaceae, such as magnolia; Malvaceae; Meliaceae; Cup-coleaceae; Moraceae, such as hemp seed or hemp; Myricaceae; Myristicaceae, such as nutmeg; Myrtaceae, such as eucalyptus, tea tree, Melaleuca alternifolia, Melaleuca alternifolia, Backhousia, clove, myrtle; Oleaceae; Piperaceae, such as pepper ; Pittosporum family; Poaceae, such as citronella, lemongrass, rockgrass; Polygonaceae; Ranunculaceae; Rosaceae, such as rose; Rubiaceae; Rutaceae, such as the entire citrus family; Salicaceae; Santalaceae, such as sandalwood; Saxifragaceae; Schisandraceae; Styracaceae, such as benzoin; Thymelaeaceae, such as agarwood; Tiliaceae; Patriniaceae, such as valerian, spikenard; Verbenaceae, such as lantana, verbena; Violaceae; Zingiberaceae, such as galangal, turmeric, cardamom, ginger; Tribulus family.

[0383] Within the meaning of the present invention, the term "pigments" is understood to mean solid particles that are white or colored and inorganic or organic.

[0384] The term "unpigmented" means that the pigment does not absorb in the visible spectrum and appears white or colorless to the naked eye.

[0385] The coated pigment is a pigment which has been subjected to one or more surface treatments of a chemical, electrical, mechanochemical and / or mechanical nature with compounds such as those described, for example, in Cosmetics & Toiletries, February 1990, Vol. 105, pp. 53-64, such as amino acids, beeswax, fatty acids, fatty alcohols, anionic surfactants, lecithin, sodium, potassium, zinc, iron or aluminum salts of fatty acids, metal alkoxides (titanium or aluminum alkoxides), polyethylene, silicones, proteins (collagen, elastin), alkanolamines, silicon oxide, metal oxides or sodium hexametaphosphate.

[0386] As is known, silicones are silicone 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 consisting essentially of recurring main units in which silicon atoms are linked together by oxygen atoms (siloxane bonds) and to which optionally substituted hydrocarbon radicals are directly attached via carbon atoms.
