Description

Use of cyclic carbonyl odoriferous compounds to inhibit and/or attenuate and/or mask the odor of UV filters, and compositions containing them

The present invention relates to the field of cosmetic products, and aims in particular to propose the non-therapeutic cosmetic use of carbonyl cyclic odoriferous compounds as a masking agent and/or as an agent inhibiting the odor of UV filters, as well as compositions comprising such compounds and one or more UV filters.

The cosmetic field to which the application of the composition, as well as the use, covered by the present invention may extend is in particular the field of makeup and/or care and/or hygiene of keratin materials, the field of sun protection, the field of hair care, or even the field of perfumes.

It is customary to introduce UVA filters and/or UVB filters, in particular organic UVA filters and/or organic UVB filters, into cosmetic compositions.

Such compounds can be dedicated to providing sun protection. They can also be useful as stabilizers, which have the role of maintaining the organoleptic properties of products stable to different aggressions, such as UVA and/or UVB and thermal shocks, in particular in perfume compositions.

Thus, a wide variety of cosmetic compositions can contain a combination of several organic and/or inorganic UVA and/or UVB filters, carried in oily phase and/or aqueous phase, and offered in various galenic forms.

However, UVA and/or UVB filters are not fully satisfactory, for example for fragile perfumes rich in natural substances.

Indeed, the presence of UVA and/or UVB filters in compositions can present cosmetic disadvantages, and in particular generate a release of a particularly unpleasant odor which constitutes a real inconvenience for users, which can limit their use in cosmetic compositions.

In view of the above, it is thus clear that there remains a need for consumers to have cosmetic and/or dermatological compositions comprising UVA and/or UVB filters, having a pleasant odor for users, while presenting advantageous cosmetic performances.

Thus, there remains a need for compounds to mask and/or inhibit and/or attenuate the unpleasant odor of UVA and/or UVB filters, particularly in cosmetic compositions.

There is also a need for compositions, particularly cosmetic ones, comprising UVA and/or UVB filters, which remain stable and homogeneous over time, particularly in terms of odor, and under the effects of light and temperature, regardless of the galenic of the composition.

The present invention particularly aims to provide compounds which are particularly effective in covering the unpleasant odor of UVA and/or UVB filters.

Thus, according to a first aspect, the present invention relates to the use of a compound of general formula (I):

formula (I) in which:
- n represents 0, 1 or 2;
- R ¹ represents a hydrogen atom or a hydrocarbon group comprising from 1 to 16 carbon atoms, cyclic or acyclic, saturated or unsaturated, conjugated or not, aromatic or not, linear or branched, optionally interrupted by one or more heteroatoms such as O, S, N; and

represents a divalent hydrocarbon group comprising from 2 to 16 carbon atoms, saturated or unsaturated, conjugated or not, linear or branched;

to inhibit and/or attenuate and/or mask the odor of UV filters.

The uses considered according to the invention are cosmetic and non-therapeutic.

The present invention also relates to a composition, in particular a cosmetic composition, comprising one or more UV filters and at least one compound of general formula (I):

formula (I) in which:
- n represents 0, 1 or 2;
- R ¹ represents a hydrogen atom or a hydrocarbon group comprising from 1 to 16 carbon atoms, cyclic or acyclic, saturated or unsaturated, conjugated or not, aromatic or not, linear or branched, optionally interrupted by one or more heteroatoms such as O, S, N; and

represents a divalent hydrocarbon group comprising from 2 to 16 carbon atoms, saturated or unsaturated, conjugated or not, linear or branched.

The invention also relates, according to another of its aspects, to a cosmetic process for perfuming and/or caring for and/or making up keratin materials, in particular the skin, comprising at least one step of applying to said keratin materials a composition according to the invention.

The cyclic carbonyl odoriferous compounds of formula (I), and in particular muscenone, are known and used in the cosmetic field, and in particular in the field of perfumes.

For example, application KR10-2019-0003160A describes compositions for improving the persistence of the effects of a perfume, which may contain muscenone.

However, to the knowledge of the inventors, the compounds of formula (I) have never been used in combination with UV filters.

However, against all expectations, and as is apparent from the examples below, the compounds of formula (I) have been characterized by the inventors as olfactory neutralizers of the odor of UV filters, and thus as being capable of attenuating and/or inhibiting and/or masking the unpleasant odor of UV filters.

Definitions

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

By " inhibit " we mean to totally or partially reduce the aspect in question, for example the unpleasant odor of UV filters.

By " attenuate " we mean reducing the intensity of the aspect in question, for example the unpleasant smell of UV filters.

By " masking " we mean completely or partially covering the aspect in question, for example the unpleasant smell of UV filters.

For the purposes of the present invention, the term " perfumed composition " or " perfuming composition " is understood to mean any composition that leaves a fragrance or odor after application to keratin materials. A fragrance is the result of a combination of different odorous substances, each providing a specific diffusing odor or " note " and evaporating at different times. More specifically, each fragrance has what is called a " top note " which is the odor that diffuses first when the fragrance is applied or when the container containing it is opened, a " heart or body note " which corresponds to the complete fragrance (emission for a few hours after the " top note ") and a " base note " which is the most persistent odor (emission for several hours after the " heart note "). The persistence of the base note corresponds to the remanence of the fragrance.

For the purposes of the present invention, the term “ perfuming substance ” is understood to mean any perfume, any odorous raw material or aroma capable of giving off a pleasant odor, in particular as defined in the remainder of the text. “ Perfuming ”, “ odorous ” or “ odoriferous ” substances are synonymous for the purposes of the present invention.

In particular, a composition according to the invention may comprise at least 0.01% by weight of perfuming substance(s) distinct from the compounds of formula (I), in particular at least 0.5% by weight, in particular at most 1% by weight, relative to the total weight of the composition.

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 even is free of perfume substance(s) distinct from the compounds of formula (I), relative to the total weight of the composition.

Perfume substances are compositions containing, in particular, the raw materials described in S. Arctander, Perfume and Flavor Chemicals ( Montclair , NJ, 1969 ), in S. Arctander, Perfume and Flavor Materials of Natural Origin ( Elizabeth, NJ, 1960 ) and in “ Flavor and Fragrance Materials – 1991 ”, Allured Publishing Co. Wheaton, Ill.

A composition according to the invention may in particular comprise at least one perfuming substance chosen from essential oils, perfumes and aromas of synthetic or natural origin, and their mixtures.

These may be natural products, such as essential oils, absolutes, resinoids, resins, concretes, and/or synthetic products, such as terpenic or sesquiterpenic hydrocarbons, alcohols, phenols, aldehydes, ketones, ethers, acids, esters, nitriles, peroxides, saturated or unsaturated, aliphatic or cyclic.

According to the definition given in the international standard ISO 9235 and adopted by the European Pharmacopoeia Commission, 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 expression). The essential oil is most often separated from the aqueous phase by a physical process that does not cause a significant change in the composition.

The choice of the method of obtaining essential oils depends mainly on the raw material: its original state and its characteristics, its nature itself. The yield " essential oil/plant raw material " can be extremely variable depending on the plants: 15 ppm to more than 20%. This choice determines the characteristics of the essential oil, in particular viscosity, color, solubility, volatility, enrichment or impoverishment in certain constituents.

Steam distillation corresponds to the vaporization in the presence of water vapor of a substance that is poorly miscible with water. The raw material is placed in the presence of boiling water or water vapor in a still. The water vapor entrains the essential oil vapor which is condensed in the condenser to be recovered in liquid phase in a Florentine vase (or essencier) where the essential oil is separated from the water by decantation. The aqueous distillate that remains after steam distillation, once the separation of the essential oil has been carried out, is called " aromatic water " or " hydrosol " or " floral distilled water ".

Obtaining by dry distillation consists of obtaining the essential oil by distilling wood, bark or roots, without adding water or water vapor in a closed enclosure designed so that the liquid is recovered in its lower part. Cade oil is the best-known example of this method of obtaining.

The cold expression method only applies to citrus fruits (Citrus spp) by mechanical processes at room temperature. The principle of the method is as follows: the zests are shredded and the contents of the secretory pockets that have been broken are recovered by a physical process. The classic process consists of exerting an abrasive action on the entire surface of the fruit under a stream of water. After elimination of solid waste, the essential oil is separated from the aqueous phase by centrifugation. Most industrial installations actually allow the simultaneous or sequential recovery of fruit juices and essential oil.

Essential oils are generally volatile and liquid at room temperature, which differentiates them from so-called fixed oils. They are more or less colored and their density is generally lower than that of water. They have a high refractive index and most of them deflect polarized light. They are liposoluble and soluble in common organic solvents, entrainable in water vapor, very slightly soluble in water.

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 botanical families: Abietaceae or Pinaceae, for example conifers; Amaryllidaceae; Anacardiaceae; Anonaceae, for example ylang; Apiaceae, for example umbellifers, in particular dill, angenic, coriander, fennel, carrot or parsley; Araceae; Aristolochiaceae; Asteraceae, for example yarrow, mugwort, chamomile, and helichrysum; Betulaceae; Brassicaceae; Burseraceae, for example frankincense; Caryophyllaceae; Canellaceae; Caesalpiniaceae, for example copaifera (copahu); Chenopodaceae; Cistaceae, for example cistus; Cyperaceae; Dipterocarpaceae; Ericaceae e.g. wintergreen; Euphorbiaceae; Fabaceae; Geraniaceae e.g. geranium; Guttiferae; Hamamelidaceae; Hernandiaceae; Hypericaceae e.g. St. John's wort; Iridaceae; Juglandaceae; Lamiaceae e.g. thyme, oregano, bee balm, savory, basil, marjoram, mint, patchouli, lavender, sage, catnip, rosemary, hyssop, lemon balm, rosemary; Lauraceae e.g. ravensara, bay, rosewood, cinnamon, litsea; Liliaceae e.g. garlic; Magnoliaceae e.g. magnolia; Malvaceae; Meliaceae; Monimiaceae; Moraceae e.g. hemp, or hops; Myricaceae; Mysristicaceae, e.g. nutmeg; Myrtaceae, e.g. eucalyptus, tea tree, niaouli, cajeput, backousia, clove, myrtle; Oleaceae; Piperaceae, e.g. pepper; Pittosporaceae; Poaceae, e.g. lemongrass, lemongrass, vetiver; Polygonaceae; Ranunculaceae; Rosaceae, e.g. roses; Rubiaceae; Rutaceae, e.g. all citrus; Salicaceae; Santalaceae, e.g. sandalwood; Saxifragaceae; Schisandraceae; Styracaceae, e.g. benzoin; Thymelaceae, e.g. agarwood; Tilliaceae; Valerianaceae, e.g. valerian, spikenard; Verbenaceae, e.g. lantana, verbena; Violaceae; Zingiberaceae, e.g. galangal, turmeric, cardamom, ginger; Zygophyllaceae.
