Definitions

• the present invention relates to an aerosol bomb containing microcapsules.
• the active product is essentially composed of a perfuming base in alcoholic solution or other solvent.
• the spraying of this active principle under the action of the propellant gas allows, to perfume the atmosphere, to distribute at will micro-droplets of perfume / alcohol mixture, in all places of residence or work, but also the automobile or any other means of public or private transport.
• Aerosols of air fresheners or room fragrances are generally low in perfume base. They are primarily intended for the deodorization of the air and the perfume which is added, acts simply as approval of use, without really being the first performance expected from the product.
• the device according to the present invention eliminates all these drawbacks. Indeed, it allows
• a spray container containing, on the one hand, one or more perfume bases composed of high quality essential oils in solution in alcohol at a concentration close to ten percent by weight, possibly associated to one or more active ingredients such as deodorant, disinfectant, relaxant or the like, these fragrance bases and active ingredients being totally or partially trapped in microcapsules and, on the other hand, a liquefied propellant of the hydrofluoroalkane type.
• fragrance concentration c r is, the mixture of the essential oils, aromatic raw materials, must be sufficiently large for the active substance vaporized in the atmosphere into fine droplets is deposited in sufficient quantity on the fabrics, curtains, seats , carpets, etc., but also on smooth and cold surfaces due to temperature difference. To obtain real effectiveness, the proportion of these perfuming bases must be of the order of 10% by weight of the solution.
• the active ingredients complementary to the perfume, as well as the perfume (perfuming base) itself will be enhanced by their imprisonment in microcapsules, for all or part of them.
• Micro-enca sulâtion is a technique which allows liquid or solid substances to be trapped in sealed microcapsules. Protected by their capsules, the active ingredients can be incorporated into the liquid phase of the aerosol, in order to isolate them from other aggressive products, which makes it possible to stabilize complex formulas.
• the microcapsules will be used to trap a substantial portion of the perfume base. Imprisoned, this perfuming base part will be released over time with a delay effect (hitherto very difficult to obtain), either by the regulated degradation over time of the envelope of the microcapsule, or by mechanical crushing, for example by walking on a carpet on which the encapsulated perfume has been previously vaporized.
• the container containing the aerosol can be glass, metal or any other material.
• the liquefied propellant selected, a hydro fluoro alkane type HFA22 which is currently one of the best suited to ecological needs, provides the desired non-wetting vaporization without the addition of solvent.
• the perfume bases will always be exclusively dissolved in perfume alcohol for around 85% by volume of the active product, in order to obtain a final product as noble as body perfumes, with all their usual qualities. It can therefore be used without damage towards fragile surfaces such as curtains, upholstery, furniture, etc. without more consequence than body scent on the skin or clothing.
• the perfume dispensed in micro-droplets will be deposited in places of accommodation, offices, vehicles, etc. to install a quality atmosphere, and moreover micro-encapsulation of some of these active ingredients and perfumes will release them with a delayed effect, therefore with a prolonged action.
