Abstract

A method for masking or modifying the olfactory or gustatory sensation generated in a user by a base product (7) includes releasing an aromatic or fragrant composition over time in a sequenced manner in relation to the release of the base product (7), the aromatic or fragrant composition being housed in at least one rupturable container (5). A device used to implement the method is also disclosed.

Description

The invention relates to the field of perfumes, scents and fragrances, and more particularly a new delivery of an aromatic or fragrant composition designed to perfume or scent a base product, initially contained in a package.
There is a certain number of situations in which a base product cannot be perfumed before its final packaging; for example, because the base product is incompatible with the aromatic or fragrant composition, or because the mixture of the base product and the aromatic or fragrant composition adversely affects the stability of the base product; or else because the aromatic or fragrant composition is unstable; or else because it is not desired that the whole of the packaged base product is perfumed or scented, for reasons that may be medical, cosmetic or quite simply for reasons of taste.
For example, in cosmetics, the smell of ammonia involved in the composition of hair colorants is a disagreeable smell that requires being masked. Hair colorants usually consist of two preparations that are designed to be mixed extemporaneously just before use. The first preparation contains alkaline agents, such as ammonia or aminated alkaline agents, which allow the hair to swell, which helps with the penetration of the pigment; the second preparation contains oxidizing agents, for example hydrogen peroxide. Particularly because of the extreme volatility of ammonia, the masking of this unpleasant smell is difficult and is the subject of much research (see for example EP1346720). Another difficulty arises from the fact that the perfumes likely to mask this smell of ammonia are not always compatible with the alkalinity of the ammonia-containing composition in question, and this incompatibility makes the masking of the smell of the ammonia yet more difficult. Patent JP2004067598 proposes that the odorizing agent that is capable of masking the smell of ammonia and that is unstable in ammonia be incorporated into the hydrogen peroxide composition to be mixed extemporaneously with the ammonia-containing composition.
In agribusiness, it is often desired to scent a product in order to create or increase a pleasant aroma or to add an aroma of freshness to a product. For example, EP 1 056 660 describes a drink receptacle cap which contains a segment molded in a synthetic material impregnated with a perfume, which diffuses the perfume so that the person perceives an aroma when he drinks.
In general, the prior art recommends, to mask a smell, creating a homogeneous mixture between the composition with the unpleasant smell and the masking agent. The inventors have now shown that, surprisingly, the masking of a smell and in particular of a very volatile smell, is more effective by deceiving, particularly by saturating, the gustatory or olfactory receptors of the user with the aid of a masking agent available through its inhomogeneous mixture with the base product, rather than with the aid of the same agent mixed homogeneously with the base product.
The object of the invention is particularly to mask or modify the olfactory or gustatory sensation generated by a base product in a user.
An objective of the invention is also to make it possible to perfume or scent a desired quantity of a base product contained in a package, without perfuming the rest of the product contained in the package. Another objective of the invention is to make it possible to perfume or scent successively small quantities of a base product extracted from a package with different aromas or perfumes or fragrances.
Another objective of the invention is to make it possible to perfume and/or scent a base product with a perfume or a scent that is generally considered to be incompatible with said base product or that is unstable in the base product, or that makes the base product unstable.
A particular objective of the invention is to cover or mask the smell of ammonia of a hair formulation, preferably of a permanent hair formulation, by using a perfume that is unstable or incompatible with one and/or the other of the two bases comprising said hair composition.
Within the meaning of the present invention, “unstable” means that the homogeneous mixture of said perfume or scent with the base product results in a significant modification of the organoleptic characteristics of said mixture.
Within the meaning of the present invention, “incompatible” means that the aromatic or fragrant composition cannot coexist with the base product for chemical reasons, for example because the coexistence induces structural modifications of the aromatic or fragrant composition or of the base product, for physical reasons, for example because the coexistence induces an undesirable change of solubility or a rheological modification of the base product, and/or for organoleptic reasons, in particular because of the possible formation of damaging products that are olfactorily or gustatorily undesirable.
“Package” within the meaning of the present invention means a receptacle in which the base product can be stored, and from which it can be extracted, expressed, taken out or poured, for its use, particularly by means of a delivery end-piece. Advantageously, the package is a bottle, in particular a flexible bottle that can be pressed in the hand to extract the product, a syringe, a tube, an aerosol or a pump. Advantageously, the package may be of the “airless” type or else a device of the type marketed under the brand SEMKIT™, or a package of the Mixpac™ System 25 type marketed by Mixpac or any package that those skilled in the art can adapt.
“Base product” within the meaning of the present invention means in particular a formulation to be perfumed or scented or whose smell must be masked, said formulation being able to be in fluid form, particularly cream, milk, lotion, gel, unguent, ointment, emulsion, gas, solid dispersion, liquid dispersion.
The invention therefore relates to a method for masking or modifying the olfactory or gustatory sensation generated in a user by a base product, characterized in that an aromatic or fragrant composition is released in a manner sequenced over time relative to the release of the base product, said aromatic or fragrant composition being contained in at least one breakable reservoir capable of releasing said composition at the desired moment(s). Advantageously, this reservoir comprises a breakable casing and a core comprising or consisting of said aromatic or fragrant composition; therefore, the casing encapsulates the volatile aromatic or fragrant composition and releases said composition when it is broken. Advantageously, this reservoir is a capsule, preferably as defined below.
According to a particular embodiment of the invention, the aromatic or fragrant composition forming the core and encapsulated in the casing is unstable and/or incompatible with the base product.
The release of the base product is a process that is capable of being spread over time. According to a preferred embodiment of the invention, a determined quantity of the base product is released. This determined quantity may be hereinafter indicated by the word “dose”.
“Release of the base product” means the extraction of the base product, or of a dose of base product, from its package.

According to a third embodiment of the method according to the invention, at least one aromatic or fragrant composition contained in at least one reservoir is released by breaking said reservoir at any moment during the release of a desired quantity of the base product.
According to a fourth embodiment of the method according to the invention, a first aromatic or fragrant composition contained in at least one reservoir is released by breaking said reservoir at any moment during the release of the base product, and at least one second aromatic or fragrant composition, identical to or different from the first, contained in at least one other reservoir is released by breaking said reservoir after the end of the release of the desired quantity of base product.
According to a fifth embodiment of the method according to the invention, at least one aromatic or fragrant composition is released after the end of the release of the base product.
Within the meaning of the present invention, “before the release of the base product” relates to a time lag preceding the start of the release of the base product, going from 0.1 to 15 seconds, preferably 0.5 to 5 seconds, very preferably from 0.8 to 2 seconds.
Within the meaning of the present invention, “during the release of the base product” relates to the time lag necessary for the release of some or all of a dose of the base product.
Within the meaning of the present invention, “after the end of the release of the base product” relates to a time lag following the end of the release of the base product, going from 0.1 to 15 seconds, preferably 0.5 to 5 seconds, very preferably from 0.8 to 2 seconds.

The invention will be better understood on reading the following detailed examples, which illustrates in a nonlimiting manner a particular embodiment of the invention and is read with respect to FIG. 1.

FIG. 1 represents a profile view of a device 1 according to the invention and of a package 2 of the base product.
The device 1 according to the invention, which may have any shape and is not limited to the graphic representation of FIG. 1, comprises reservoirs 5. In the embodiment of FIG. 1, these reservoirs are capsules consisting of a casing 6 and a core consisting of the aromatic or fragrant composition.
A base product 7 is situated in the package 2. This package 2 comprises an extraction orifice 3, or end-piece, capable of delivering the base product for the purpose of its use. The device 1 comprises an end 4 that can be adapted to the extraction orifice 3, The user may manually adapt the device 1 to the end-piece 3. According to a particular embodiment of the invention, not shown, the device 1 is attached to the end-piece 3 prior to the use of the base product.
When carrying out the manipulations necessary to deliver the base product, the user expresses the base product 7 from the package 2 via the end-piece 3 on which the device 1 is placed. The product expressed through the end-piece 3 comes into contact with the capsules 5. The capsules break under the mechanical action of the base product 7 that is propelled by the user into contact with the capsules 5 with sufficient pressure to break them, or under the chemical effect of solubilization of the casing by the base product, or under the effect of a breaking means present in the device, or under the effect of the mechanical pressure of the user on the device. Some or all of the capsules 5 may break. The capsules 5 may break simultaneously or successively. When they break, they release the aromatic or fragrant composition that they contain, which can mix with the base product 7. In a particular embodiment of the invention, not shown, the device 1 comprises a means of mixing the base product and the aromatic or fragrant composition, said means of mixing comprising mixture elements. Depending on the number and size of the mixture elements, a more or less homogeneous mix is obtained, which allows those skilled in the art to obtain the desired effect of coverage or perfuming.

EXAMPLE 1

A simple bayonet static mixer of the MA STATOMIX type made of polypropylene marketed by MIXPAC Systems, furnished with mixture elements, is used. The mixture elements are cut so as to be able to cause the breakable capsules marketed by MANE to enter in the desired quantity, namely the sufficient quantity to obtain a dose of perfume identical to that which would be used in a commercial intimate mixture product. The identification of this dose is within the competence of those skilled in the art.
The hair coloring product is prepared in a flexible plastic bottle with a sectile cap of the type marketed by l'Oréal for its Excellence Crème™ products of l'Oréal Paris™, or by Henkel for Schwartzkopf Vision Color Relief™, or else by Clairol for Perfect Blondes™, by Eugéne Perma for Eugéne Color™ or Keranove™, and by Mandom for Gatsby™. The hair coloring product is obtained by mixing the ammonia-containing base on the one hand and the oxidizing portion on the other hand, then stirring the mixture. The sectile cap is cropped, and the bottle then becomes a package of the base product of which the hair coloring mixture is made. Before delivery, the static mixer furnished with the capsules is adapted to the end-piece thus opened.
The mixture of base product is expressed from the flexible plastic bottle or boiling vessel by pressure on the walls of said bottle. The mixture comes into contact in the mixer with the capsules. Under the pressure of the product, the capsules break successively when the product passes. The base product and the liquid perfume released by the capsule are sheared by the mixture elements and then expressed.

EXAMPLE 2

A static mixer of the MA STATOMIX type made of polypropylene marketed by MIXPAC Systems, furnished with capsules containing an aromatic or fragrant composition, is adapted to the end-piece of a MIXPAC Systems S25 pistol furnished with 50 ml two-compartment cartridges. Each portion of the formulation is present in its compartment; it is sufficient to connect the device (twist-lock) and to install the cartridge in the pistol furnished with the button corresponding to the chosen cartridge. The pressure on the trigger of the pistol actuates the pistons which inject the two portions of the formulation into the device of the invention. The advantage provided by the use of the pistol is to be able to use products with a very viscous base.
