Description

METHOD FOR INGESTION SCRAPING OF AT LEAST TWO EDIBLE SCENIC SUBSTANCES HAVING DIFFERENT MAXIMUM DIFFUSION TIMES; The invention relates to a process for the perfuming of human keratin materials which consists in simultaneously or separately ingesting: a) at least one first edible perfuming substance (1) capable, after ingestion, to produce, from the interior of the body to the human keratin materials, a perfume whose diffusion reaches its maximum at a time less than 4 hours 30 with b) at least a second edible perfuming substance (2) capable of producing, from inside the body to on human keratin materials, a perfume whose diffusion reaches its maximum at a time greater than or equal to 4 hours 30 minutes.

We know that a perfume is the combination of different odorous substances that evaporate at different times. It is possible to classify a fragrance according to its olfactory family, and to describe it according to the notes that appear during its use. These olfactory notes are differentiated into top notes (those linked to the first olfactory impression and are the most volatile), heart notes (those which constitute the heart of the perfume and remain for several hours), and finally base notes ( those that persist long after the perfume has been vaporized and may remain on a garment for months). Some perfumes, however, may have a different olfactory construction, namely having only one or two of these notes.

The human being has always sought to perfume and perfume the objects that surround him or the places in which he is, and this, both to mask strong odors and / or unpleasant than to give good odour.

It is common to incorporate perfume in a number of products or compositions, in particular cosmetic and dermatological such as fresh water, eau de toilette, perfume waters, elixirs or perfume extracts, aftershave lotions, care waters. However, the persistence and the intensity of the perfume in these formulations remain however limited in time. They decrease substantially in less than 6 hours.

For some years now, products improving or modifying the smell of the body have been appearing on the market after ingestion of particular edible perfuming substances. These products have the role either to limit bad body odors (deodorant axis) or to perfume the skin subtly (perfume axis).

45 One of the first products to appear on the market is a 2004 Brazilian product (FIBER SENSE) based on coriander oil, positioned as an anti-cholesterol medicine but one of the side effects would be to pleasantly perfume the skin of the interior. .

Many products positioned in the deodorization axis of the body also appear on the oral cosmetics market and contain chlorophyll derivatives such as chlorophyllin. These products are sold to limit bad odors. Such products are described in particular in JP10245343 (Taisho Pharmaceutical Co.), WO 200410574 (Mitchell Kurk Lawrence, NY) and JP2002224203.

In the Asian market of oral cosmetics, products have also been observed claiming this time a "perfume" of human ketatin materials by ingestion of edible products containing edible perfuming substances capable of diffusing from the inside of the body an odor on the skin. human keratin materials especially the skin. These products are sold in the form of confectionery, drinks, chewing gums, or capsules. They are described in particular in Chinese Patent CN 1217889 (LIU) disclosing products containing mint, vanillin, geraniol, and vitamins for the purpose of perfuming the fluids of the human body.

Also known from application WO 2006129876 of Kanebo Foods Ltd are ingestible cosmetic products, preferably candies or chewing gums comprising at least one polar compound and / or terpene perfuming the body after ingestion with edible fragrance molecules such as geraniol, linalool and citronellol. Since 2006, KANEBO has been selling chewing gums under the trade name FUWARINKA for the purpose of perfuming the skin inside (made from geraniol, rose and lemon essence). The company WAKASA sells capsules under the brand "SOFIA" based on rose essence.

During its many researches, the Applicant has found that the intensity and persistence of the odor diffused from the inside of the body on human keratin materials by these edible perfume formulations were not satisfactory after a period of minus 6 hours.

Edible perfume molecules able to diffuse from the inside of the body a perfume on the human keratin materials after ingestion do not all have the same olfactory effect in intensity and withstand time. Some have weak olfactory diffusion initially after ingestion, which reaches its maximum after 3 hours and then decreases. For other molecules, the olfactory diffusion can reach its maximum beyond 4 hours 30 or more and then decrease.

There remains therefore the need to search for new perfumes intended to be applied orally which, after ingestion, to diffuse from the inside of the body a perfume on human keratin materials, in particular the skin whose intensity remains homogeneous, effective and constant from 1 hour 30 to 6 hours at least.

The Applicant has surprisingly discovered that this objective can be achieved by a process for perfuming keratin materials which consists of ingesting, simultaneously or separately: a) at least one first edible perfuming substance (1) suitable, after ingestion or in the mouth, to produce, from inside the body on human keratin materials, a perfume whose diffusion reaches its maximum at a time less than 4 hours 30 and b) at least one second edible perfuming substance (2) suitable, after ingestion or mouthing, to produce, from the inside of the body to the human keratin materials, a fragrance whose diffusion reaches its maximum at a time greater than or equal to 4 hours 30 minutes.

According to the definition given in the international standard ISO 9235 and adopted by the European Pharmacopoeia Commission, an essential oil is a fragrant product generally of complex composition, obtained from a botanically defined plant raw material, either by training in the water vapor, either by dry distillation or by a suitable mechanical process without heating (cold expression). The essential oil is most often separated from the aqueous phase by a physical process which does not result in a significant change in the composition. 25 Modes of obtaining essential oils

The choice of the technique depends mainly on the raw material: its original state and its characteristics, its nature proper. The yield "essential oil / vegetable raw material" can be extremely variable according to the plants: 15 ppm to more than 20%. This choice conditions the characteristics of the essential oil, in particular viscosity, color, solubility, volatility, enrichment or depletion in certain constituents.

Training with water vapor

Steam training corresponds to the vaporization in the presence of water vapor of a substance that is not very miscible with water. The raw material is brought into the presence of boiling water or water vapor in a still. The water vapor causes the essential oil vapor which is condensed in the refrigerant to be recovered in liquid phase in a florentine (or essencier) vase where the essential oil is separated from the water by decantation. The aqueous distillate which remains in steam distillation after the separation of the essential oil is called "aromatic water or" hydrosol "or" floral distilled water ".

Dry distillation The essential oil is obtained by distillation of wood, barks or roots, without the addition of water or water vapor in a closed chamber designed for the liquid to be recovered in its lower part. Cade oil is the best-known example of this method of production.

Cold expression

This method of production only applies to citrus fruits (Citrus spp.) By mechanical processes at ambient temperature. The principle of the method is as follows: the zests are dilacerated and the contents of the secretory sacs that have been ruptured are recovered by a physical process. The conventional method consists in exerting under a stream of water an abrasive action on the entire surface of the fruit. After removal of solid waste, the essential oil is separated from the aqueous phase by centrifugation. Most industrial plants actually allow the simultaneous or sequential recovery of fruit juice and essential oil.

Physico-chemical characters.

Essential oils are usually 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 deflect polarized light. They are liposoluble and soluble in the usual organic solvents, entrainable with water vapor, very little soluble in water. Among the essential oils that may be used according to the invention, mention may be made of those obtained from the plants belonging to the families. following botanicals:
