Definitions
- the invention relates to granules, perfume testers or perfumes, their manufacturing processes and their uses.
- testers are used.
- the known testers of the state of the art are small flasks generally made of glass, which contain a few milliliters of perfume in liquid form essentially comprising an alcoholic vehicle and odorous compounds. It is often very small models of bottles for sale with cap, dropper or spray device.
- a problem to be solved by the invention is to produce a granule, perfume tester or perfume which does not have the above-mentioned drawbacks of prior art testers, and which makes it possible in particular to performing tests on specific areas of the skin.
- the proposed solution of the invention to this problem posed first object a granule, characterized in that it comprises a friable peripheral portion incorporating odorous compounds, said friable peripheral portion being able to disintegrate in the form of a powder perfume when said granule is applied to the skin, and in that it has an average diameter greater than about 4 mm.
- it has the second object a method of manufacturing a granule as defined above, characterized in that it implements a granulation.
- Its third object is the use of a granule as defined above, characterized in that said granule is applied to the skin so as to disintegrate its friable peripheral portion.
- the granule according to the invention further comprises an inner portion forming a hard core, the constitution of this inner portion being different from that of the peripheral portion;
- the granule is substantially spherical with a mean diameter of between about 4 mm and about 30 mm, and preferably between about 8 mm and about 15 mm;
- the average diameter of the inner portion of the core granule is greater than about 2 mm and the thickness of the peripheral portion of said granule is greater than about 1 mm;
- the friable peripheral portion comprises odorous compounds, a binder and an inert vehicle formed of a powder;
- the binder comprises a wax;
- the inner part forming a core comprises between 2 and 50% by weight of the total weight of said part of gums;
- the granule does not comprise a hard core and is formed of a controlled friability mass to release a scented powder by disintegration under the effect of friction with the skin or the application of a sufficient pressure;
- the granule according to the invention, tester or perfume is in solid form.
- the application of the tester is performed on a specific skin area defined by its displacement directly on the skin. It is possible to test a plurality of perfumes and even to consider, with testers comprising different perfumes, perfume overlay tests.
- Figure 1 shows, in perspective, a granule, perfume tester or perfume according to the invention, consisting of a core having a peripheral portion and an inner portion forming a core
- Figure 2 illustrates the various steps of a method of manufacturing a granule, perfume tester or perfume according to the invention
- Figure 3 shows, in perspective, a method of using a granule, perfume tester or perfume according to the invention, when applied to the skin.
- FIG. 1 there is shown a granule, perfume tester or perfume according to the invention.
- This perfume tester or perfume comprises a substantially spherical granule with an average diameter greater than about 4 mm, and preferably between about 4 mm and about 30 mm, and even more preferably between about 8 mm and about 15 mm.
- the granule comprises, on the one hand, an inner or inner core portion 11 and, on the other hand, a peripheral portion 12 constituting a shell.
- the core 11 is substantially spherical in average diameter greater than about 2 mm, preferably between about 5 mm and about 10 mm.
- the core 11 optionally comprises several sub-layers made by successive coating of a core. However, its constitution is homogeneous from its heart to its periphery.
- the core 11 is stable, compact and has a certain hardness. This hardness is such that a user of the tester according to the invention, which would apply a reasonable pressure on the surface of the core 11 by holding it between his thumb and forefinger, could disaggregate it.
- the core 11 comprises between 2% and 50% and, preferably, between 5 and 20% by weight of gums, in particular plant and / or synthetic gums.
- gums which may be used for the manufacture of the core 11, mention may be made of Water-soluble gums such as gum arabic, carrageenans, alginates, pectins, karaya gum, xanthan gum, chitosan or its derivatives, hyaluronic acid, pullulan or agar polymers, dextran, celluloses and their derivatives such as methylcellulose or hydroxypropylcellulose, acrylic acid polymers crosslinked with an allyl ether, such as those known under the generic name of carbomers, essentially consisting of a carbomer or a mixture of carbomers such as polymers acrylic acid crosslinked with polyalkenyl ethers under the name Carbopol TM.
- the core further comprises 20% to 80% by weight of an inert crystallized substance such as talc or any other crystalline inert substance for cosmetic use. It finally comprises a residual amount of water, for example between about 1% and about 6% by weight of the total weight of the core, a residual amount of alcohol and odorous compounds.
- the shell 12 is in the form of a layer covering the entire core 11. Although this is not generally the case, it is likely to consist of a plurality of sub-layers.
- the thickness of the shell 12 is substantially constant along the surface of the core 11. In practice, it is greater than about 1 mm and, preferably, of the order of 2 mm.
- the hardness of the shell 12 is much less than that of the core 11 so that, unlike the core 11, the shell 12 is friable.
- This friability is such that, under the effect of a reasonable pressure that would be applied by a user holding a tester according to the invention between his thumb and forefinger, the shell 12 would disintegrate in the form of a fragrant powder of fines odorous particles of a few microns in average diameter.
- the fragrant, fragrant or scented powder may also be in the form of a thin layer, more or less homogeneous depending on the amount of binder contained in the peripheral layer 12 of the granule 10, left on the skin after application and / or friction by a user and disintegration of the shell 12.
- the chemical nature of the shell 12 is different from that of the core 11. Indeed, the shell 12 comprises a substantial amount of an insulating binder, substantially impermeable, and filming. Thanks to this binder, the evaporation of odorous compounds is limited.
- the binder present at more than 1% by weight of the total weight of the shell 12, consists in particular of natural waxes, of animal or vegetable origin, or artificial waxes.
- the shell 12 includes a substantial amount of scented compounds. Indeed, and as will be detailed in the following description, for the manufacture of the hull 12, a mixture comprising more than 40% and up to 70% by weight of liquid perfume whose alcoholic vehicle is subsequently largely evaporated.
- the shell 12 comprises an inert solid vehicle consisting of a finely crystallized substance. It is for example talc or other inert crystalline substances for cosmetic use. In practice, the crystallized substance chosen will be identical to that used for the constitution of the core 11. Finally, the shell 12 comprises a residual amount of alcohol.
- the granule does not comprise a hard core. It is then formed of a relatively homogeneous mass whose friability is controlled for the release of powder by disintegration in particular its periphery under the effect of friction with the skin or the application of sufficient pressure directly on the skin. Note however that the entire granule is likely to be friable so that an individual wishing for example perfume or perfume an object or a solution, degrades the granule in the form of a perfume powder.
- granulation is carried out in the presence of a powdery solid phase formed by the crystallized inert substance and of a liquid or pasty phase comprising the gum, perfume comprising an alcoholic vehicle and odorous compounds, water and alcohol.
- the components of the liquid or pasty phase can be added one after the other. Quantitatively, if, for example, 100 g of powdery solid phase is used for the granulation, then between 5 to 15 g of gum, 25 and 45 g of water, 25 to 45 g of alcohol and 10 g of water will be used. to 30 g of perfume.
- the granulation is carried out substantially at ambient temperature and in the presence of a hygrometry of less than 70%.
- the desired final dimensions of the core 11 are reached by successive coatings. These coatings are made by spraying the aforementioned liquid or pasty phase and then dusting the powdery solid phase. Crystallized (step 21, FIG. 2). Drying 22 is performed at the end of each coating step 21.
- the drying temperature is between about 40 ° C. and about 55 ° C. and preferably between about 45 ° C. and about 50 ° C.
- the drying time is greater than
- sieving is carried out 23.
- the meshes of the sieves are adapted to obtain cores 11 of desired size.
- the subsequent steps relate to the manufacture of the outer shell 12.
- this liquid or pasty phase comprising wax is firstly prepared, perfume in a conventional form comprising an alcoholic vehicle and odoriferous compounds, and alcohol.
- this liquid or aqueous phase comprises between 30 and 50% by weight of wax, between
- This liquid or pasty phase is then sprayed on the cores 11 (step 24, FIG. 2).
- This phase ensures, in particular, the adhesion of the shell 12 to the core 11.
- the whole is dusted with the inert crystalline powdery phase.
- a last drying is then carried out at temperatures between about 40 ° C. and about 55 ° C., and preferably between about 45 ° C. and about 50 ° C., for example of the order of 45 ° C. in order to obtain the perfume granules forming testers or the perfume according to the invention.
- testers or these perfumes are likely to be stored and kept for a relatively long time, for example of several months or so, without alteration of their odorous qualities.
- a user takes a granule 10 according to the invention between his thumb 30 and his index finger 31. then applies this tester granule to the surface of a cutaneous area 32 that he chooses, for example on the back of his hand. It applies a slight pressure on the tester and moves it along the chosen skin surface, for example in the direction of the arrow 33. The pressure and the friction generated by the tester moved in contact with the skin induces a degradation of the shell friable 12 likely to leave a smelly powdery trail 34. Only the hull 12 is degraded.
- the area of the powder trail which corresponds exactly to the odor zone, is precisely defined by the displacement of the tester on the surface of the skin. It is then enough for the user to feel this area to fully appreciate the fragrance and check the compatibility of it with his skin. The powder trail may subsequently be easily removed. However, if the user wishes to test another perfume, it is then enough for him to choose another tester prepared with this other perfume and to apply this tester in another cutaneous zone. It will be easy to differentiate areas, given the powdery traces left by the tests. The user can even, if he wishes, perform tests of association of perfumes or odors.
- the odor comes mainly from the odorous compounds associated with the inert vehicle of the damaged shell under the effect of the friction of the tester and the skin. It is therefore a solid tester delivering a perfume in a dry form and not liquid, as in the state of the art.
- this dry source of perfume contains substantially no alcohol. Thereby, people, who do not wish or can not be in contact with alcohol for medical, ethnic or religious reasons, will be able to test perfumes using a tester according to the invention, or even perfume by means of a perfume according to the invention.
- the user can keep the perfume tester. Fragranced in its mass, the compact core will release a pleasant scented sensation for many weeks.
- Example 1 Serena TM Perfume Testers The Technabio TM process is granulated from equal amounts of a powdery solid phase of talc and the following liquid phase, the percentages being given by weight of the total weight of the phase liquid:
- the granules thus obtained are dried in an oven for 1 hour, at temperatures between 45 and 50 ° C. Then screening is carried out with meshes of 5, 6 and 6.5 mm in diameter. Calibrated granules of 460 g average weight are then obtained. These granules constitute the nuclei of the testers according to the invention.
- a coating of the calibrated cores after sieving is carried out in the aforementioned granulator in three passes.
- the total weight of the cores before coating is 460 g and the total weight of the test granules, after coating and drying for 30 minutes, is 548.6 g.
- Granulation is carried out according to the process
- Liquid Prunelle TM Fragrance 20,00% The order of addition of the constituents of the liquid phase is as follows: water, gum arabic, alcohol then perfume Prunelle TM.
- Drying of the granules thus obtained is carried out in an oven for 1 hour, at temperatures of between 45 and 50 ° C. Then sieving is carried out with meshes of 5, 6 and 6.5 mm in diameter. Calibrated granules of 210 mg average weight are then obtained. These granules constitute the cores of testers I 1 according to invention.
- a coating of the calibrated cores after sieving is carried out in the aforementioned granulator in three passes.
- the total weight of the tester granules, after coating and drying for 30 minutes, is 548.6 g, when 400 g of pellet cores are used.
- testers or perfumes according to the invention can be carried out in a fluidized bed or by means of any other device or plant capable of producing granules.
