(2) the placing in the mouth and/or the placing in contact with the lips of at least one edible composition (B) comprising at least one edible fragrancing substance capable of producing a fragrance in the oral cavity and/or on the lips; the said edible fragrancing substance being chosen such that the composition (B) produces a fragrance having at least one note in common with at least one of those of the fragrance produced by composition (A) ; the order of the steps not being critical, and the application of compositions (A) and (B) can be simultaneous or at different times.

The invention also relates to a kit or device for fragrancing human keratin materials, containing at least two conditionings, characterized in that it comprises

- a first conditioning comprising composition (A) as defined previously;

- a second conditioning comprising composition (B) as defined previously.

Man has since time immemorial sought to fragrance himself and to fragrance the clothes he wears, the objects surrounding him or his environment, both to mask strong and/or unpleasant odours and to give a good odour .

It is known that a perfume is a combination of different odoriferous substances that evaporate at different periods. It is possible to classify a perfume according to its olfactory family, and to describe it as a function of the notes that appear during its use. These olfactory notes are differentiated into head notes (those associated with the first olfactory impression and which are the most volatile) , heart notes (which constitute the body of the perfume and remain for a few hours) and finally base notes (which persist for a long time after the perfume has vaporized and which may remain on clothing for months) . Certain perfumes may, however, have a different olfactory construction, namely they may have one or two of these notes .

It is common practice to incorporate perfume into a certain number of products or compositions, in particular cosmetic and dermatological compositions applied directly via the topical route onto keratin materials, in particular the skin. It is common practice to incorporate perfume into a certain number of products or compositions, in particular cosmetic and dermatological compositions applied directly via the topical route to keratin materials, in particular the skin. These products are generally in the form of eau de toilette, eau de parfum, aftershave lotion, eau de soin or eau fraiche.

There has also been a need for many years in the case of men and women to fragrance the mouth in order to make the breath and the lips pleasant.

Various oral hygiene products have been proposed, for instance toothpastes, oral mouthwash solutions or oral gels. These formulations are generally aimed at deodorizing the mouth, fragrancing it, eliminating microorganisms that are capable of generating unpleasant odours, or affording additional effects such as freshness and its substantivity, or various other effects .

Examples that may be mentioned include:

- patent application JP 2004010485 (Kao) , which proposes to improve the substantivity of a fragrance adapted to the oral cavity, by using a particular galenical composition;

- patent application JP 2001220335 (Kao) , which proposes to use a fragrance adapted to the oral cavity, combined with a sodium alkyl sulfate for obtaining a particular pH;

patent JP 9031487 (Kanebo) , describing a fragrance adapted to the oral cavity and also having a tranquillizing effect;

- patent JP 9104891 (Lion Corp.)_/ describing a fragrance adapted to the oral cavity, also having a refreshing effect (1-menthol cited);

- patent JP 63066115 (Lion Corp.), describing a composition aimed at combating tobacco odours, the composition comprising perfume ingredients, plant oils and zinc derivatives (chloride, citrate, acetate) ;

patent JP 2827500 (Lion Corp.), describing a fragrance composition adapted to the oral cavity, necessarily comprising four different families of aldehydes, for combating unpleasant odours;

patent application JP 2007099782 (Takasago) , which describes a fragrancing composition with antibacterial activities, suitable for specifically combating bacteria of the oral flora.

In the food sector, there are also products claiming purification of the breath, such as chewing gums, coated sweets or certain confectioneries. The active agents used in products of this type are the starting materials commonly used in this sector (flavourings) , such as aromatic essential oils, synthetic or natural compounds, such as menthol, eucalyptol, or other flavourings used in the food industry (cinnamon derivatives, etc.). Often, the flavourings used are directed towards reproducing an odour or taste of a natural compound (mint, fruits, etc . ) .

However, the range of fragrances proposed for the mouth by formulations of this type remains very limited. They are generally unsubtle and sparingly sophisticated for the consumer, as are standard perfumes applied directly to the skin, the body or keratin materials.

There is still a need to find novel fragrancing formulations for fragrancing the oral cavity and the lips, which can produce fragrances of the same type as those proposed in standard perfumery.

Products for improving or modifying the odour of the body after ingestion of particular edible fragrancing substances have appeared on the market in recent years. These products have the role either of limiting unpleasant body odour (deodorant type) or of subtly fragrancing the skin (fragrancing type) .

One of the first products that appeared on the market is a Brazilian product from 2004 (Fiber Sense) based on essence of coriander, which was presented as an anticholesterol medicament, but one of the side effects thereof was that of pleasantly fragrancing the skin from within.

Many products aimed at deodorizing the body also appear on the oral cosmetics market and contain chlorophyll derivatives such as chlorophylline . These products are sold for limiting unpleasant body odour. Such products are described especially in the documents JP 10245343 (Taisho Pharmaceutical Co.), WO 2004/10574 (Mitchell Kurk Lawrence, NY) and JP2002224203.

Products this time claiming "fragrancing" of human keratin materials via the ingestion of edible products containing edible fragrancing substances capable of diffusing from within the body an odour onto human keratin materials, in particular the skin, have also been observed on the Asiatic oral cosmetics market. These products are sold in the form of confectionery, drinks, chewing gums or gel capsules. They are especially described in Chinese patent CN 1217889 (Liu) disclosing products based on mint, vanillin, geraniol and vitamins for the purpose of fragrancing human bodily fluids. The patent application WO 2006/129 876 from Kanebo Foods Ltd also discloses ingestible cosmetic products, preferably sweets or chewing gums, comprising at least one polar compound and/or terpene that fragrances the body after ingestion with edible fragrancing molecules such as geraniol, linalool and citronellol. The company Kanebo has been selling since 2006 chewing gums under the trade name Fuwarinka for the purpose of fragrancing the skin from within (based on geraniol, essence of rose and lemon) . The company Wakasa sells gel capsules under the brand name "Sofia" based on essence of rose.

There is still a need to find a process for fragrancing the mouth in accordance with a fragrance applied topically directly to keratin materials or to clothing.

The Applicant has discovered, surprisingly, that this objective can be achieved with a fragrancing process that includes the following steps:

(2) the placing in the mouth and/or the placing in contact with the lips of at least one edible composition (B) comprising at least one edible fragrancing substance that can produce a fragrance in the oral cavity and/or on the lips; the said edible fragrancing substance being chosen such that composition (B) produces a fragrance having at least one note in common with at least one of those of the fragrance of composition (A) ; the order of the steps not being critical.

This discovery forms the basis of the invention.

The invention relates to a fragrancing process that includes the following steps:

(1) the direct application to human keratin materials or to clothing of a fragrancing composition (A) comprising, in a cosmetically acceptable medium, at least one fragrancing substance; the same composition producing a fragrance with a head note and/or a heart note and/or a base note;

(2) the placing in the mouth and/or the placing in contact with the lips of at least one edible composition (B) comprising at least one edible fragrancing substance that can produce a fragrance in the oral cavity and/or on the lips; the said edible fragrancing substance being chosen such that composition (B) produces a fragrance having at least one note in common with at least one of those of the fragrance of composition (A) ; the order of the steps not being critical and the application of compositions (A) and (B) can be simultaneous or at different times.

The invention also relates to a fragrancing kit or device with at least two conditionings, characterized in that it comprises

- a first conditioning comprising composition (A) as defined previously;

- a second conditioning comprising composition (B) as defined previously.

The term "human keratin materials" means the skin (of the face, body or the lips) , the scalp, the hair, the eyelashes, the eyebrows, the nails or mucous membranes .

The term "fragrancing substance" means any fragrance or aroma capable of giving off a pleasant odour .

The term "edible composition" means any non-toxic composition suitable for application in the oral cavity and on the lips.

The term "edible substance" means any non-toxic substance suitable for application in the oral cavity and on the lips.

The term "cosmetically acceptable medium" means a non-toxic medium that may be applied directly to the skin (face, body and lips) , the scalp, the hair, the eyelashes, the eyebrows, the nails and mucous membranes .

The term "different times" means time intervals between the application of composition (A) and the application of composition (B) . The user may thus successively apply composition (A) and composition (B) , the order being irrelevant, after a few seconds or after several hours in the same day, especially within an interval ranging from 30 seconds to 12 hours.

The fragrancing composition (A) according to the invention may be in aqueous or anhydrous form, or in liquid, pasty or solid form.

The fragrancing composition (A) according to the invention may constitute a composition for fragrancing, caring for or treating keratin materials, and is especially in the form of a fragrance, an eau de parfum or eau de toilette, an eau fraiche, an aftershave lotion, an eau de soin or a silicone-based or hydrosilicone-based care oil. It may also be in the form of a fragranced two-phase lotion (for example hydrophilic phase/hydrocarbon-based oil phase and/or silicone oil phase) . It may also be in the form of a gel, balm or concrete.

It may also be in the form of a fragranced milk or cream (oil-in-water emulsion, water-in-oil emulsion or multiple emulsion of the water-in-oil-in-water or oil- in-water-in-oil type) .

It may also be in the form of a powder such as fragranced talcs.

The fragrances as used in composition (A) are compositions especially containing the starting materials described in S. Arctander, Perfume and Flavor Chemicals (edition 2003) and in "Flavor and Fragrance Materials - 1991", Allured Publishing Co. Wheaton, 111.

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

According to the definition given in international standard ISO 9235 and adopted by the Commission of the European Pharmacopoeia, an essential oil is an odoriferous product generally of complex composition, obtained from a botanically defined plant raw material, either by steam entrainment, or by dry distillation, or via 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 .

Modes for obtaining essential oils

The choice of technique depends mainly on the starting material: its original state and its characteristics, its actual 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, richness or poorness in certain constituents .

Steam entrainment

Steam entrainment corresponds to vaporization in the presence of steam of a sparingly water-miscible substance. The starting 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 and 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 entrainment, once the separation of the essential oil has been performed, is known as the "aromatic water" or "hydrolate" or "distilled floral water".

Dry distillation

The essential oil is obtained 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.

Cold pressing

This production method 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 standard 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.

Physicochemical characteristics 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, entrainable with steam, and very sparingly soluble in water.
