    PREPARATION OF EXPANDED PERLITE AND ITS USE IN PRODUCTS FOR
    SMOKING IN WATER PIPES
    SECTOR OF THE TECHNIQUE
    The present invention relates to the preparation and use of expanded perlite as an absorbent and support material for the evaporation of flavored liquids when heated in a water pipe, thus constituting the mixture of expanded perlite and liquid, a new product for Smoking in water pipes.
    BACKGROUND OF THE INVENTION
    Perlite is a natural mineral of volcanic origin that contains sodium, potassium and aluminosilicate, classified under CAS number 93763-70-3, and that at high temperatures is transformed by expansion giving rise to the mineral called expanded perlite. The resulting expanded perlite is a low density mineral (between 50 and 125 kg / m3), porous, with remarkable absorption capacity, insoluble in water and solvents, inert, and which is classified as non-toxic, which is why it is authorized For use in horticulture and other applications.
    The applications of expanded perlite are in general very widespread, being one of the main ones its use as a component of building materials, as is the case of its use in mixtures of light cements with high performance (as cited in US2016289121 (A1), entitled “HIGH STRENGTH CONCRETE COMPOSITION AND METHOD”). The use of expanded perlite has also been described for the preparation of acrylic coatings with fire retardant properties, in particular for the protection of bamboo constructions (CN105694621 (A), “Fireproof coating for household bamboo products”). In application KR101637322 (B1), "COMPOSITION CONTAINING APPLE POMACE EXTRACT AS EFFECTIVE COMPONENT", the use of perlite is proposed in a filtration process of ethanolic extracts of natural waste, based on the porosity of the expanded perlite and its inert character . Also, in the application US2016303001 (A1) “POWDERY COSMETIC COMPOSITION” by Tsubata Kazuyoshi, the inclusion of

    perlite sprayed in proportions between 5 and 70% by weight in powdery products for cosmetic use. The diversity of applications of expanded perlite is high, for example the invention CN105669291 (A) "Nutrient medium for raising seedling of Cestrum purpureum and preparation method thereof", describes its use in nutrient media for the growth of Cestrum purpureum, which include in Its composition includes various plant and mineral components apart from the expanded perlite, and which result in an adequate system of transplantation and growth of the buds, all taking advantage of the non-toxic and environmentally compatible nature of the expanded perlite. Another application of expanded perlite is based on its incorporation into the treatment of paper pulp in the process of manufacturing paper varieties that show special rigidity, stability and resistance, as described in US2016194829 (A1) "PAPER PULPING PROCESS AND COMPOSITION ”.
    Among all the applications described for expanded perlite, none has been found that refers to its use associated with water pipes, hookah or shisha, nor has any reference been found where it is used as a support for evaporation by heating of liquids To smoke in water pipes.
    Although there are various materials mixed with liquids described for use in water pipes, none of them consists in the use of expanded perlite in the terms described in the present invention. Thus, in the patent DE 198 54 009 C2 the use of aluminum oxide, silica gel, cellulose, lignin granules, zeolites, aluminas and combinations thereof is proposed. In WO 2009/010176 A2 and DE 10 2007 043 776 A1, the use of dolomite, montmorillonite, or diatomaceous earth is proposed. The use of clinoptilolite (a variety of zeolite) is mentioned in DE 20 2010 004 671 U1. The zeolite is also postulated for use in water pipes in US2014305456 (A1) "AEROSOL-FORMING MATERIAL FOR A HOOKAH". Finally, in US2014069446 (A1) "TOBACCO FREE HOOKAH SMOKING SYSTEM" the use of porous spheres based on synthetic materials or recycled glass is described.
    The authors of the present invention have surprisingly observed that the expanded perlite authorized for agricultural use can be treated and adapted passes its use to smoke liquid preparations in water pipes, for this it is necessary to clean and select the expanded perlite so that the material It is suitable for this use.

    EXPLANATION OF THE INVENTION
    The object of the present invention comprises the use of expanded perlite as an inert mineral support for evaporation by heating of liquids in water pipes (also known internationally as hookha, shisha or hookah). The heating of the prepared product based on a mixture of flavored liquid and expanded perlite (conveniently treated and selected) in a water pipe produces a rapid evaporation effect, which after passing through the water pipe results in a remarkable generation of smoke formed mainly by water vapor and aromas, obtaining the effect of smoking.
    The treatment of expanded perlite for agricultural use is also part of the object of the invention, making it a solid support suitable for use in water pipes. The expanded perlite for agricultural use is subjected to a process of washing and selection of particle size, which leads to the obtaining of clean and dry expanded perlite, of size between 3 and 6 mm in diameter of particle, and devoid of typical powdery remains of the starting material, and which would interfere with the use provided for in the present invention.
    Also part of the object of the invention is the use of expanded perlite, conveniently treated and selected, mixed with liquids composed of some of the following components: glycerin, propylene glycol, polyethylene glycol 400 and aromas, resulting in a mixture that can be smoked by heating in a water pipe.
    PREFERRED EMBODIMENT OF THE INVENTION
    The expanded perlite for agricultural use is a solid material composed of particles ranging from powder material to grains 6-7 mm in diameter. Under these conditions the material is not suitable for use in a water pipe since the dispersion of particle size and high dust content advise against its use due to the danger of inhaling light particles both in handling and in the intended use in the present invention. In order to use the expanded perlite it is therefore necessary to select light and porous particles of large size within the range of the material, that is between 3 and 6 mm in diameter, neglecting the heavy particles, the smaller ones and eliminating the powdery fraction contained in the original material.

    Part of the object of the invention is a process for conditioning the expanded perlite by means of which an amount of expanded perlite is taken and sieved through a sieve of 3 or 4 mm in diameter to remove small particles, in some adequate conditions of air extraction and protection due to the significant powder content that is easily suspended in the air and may be counterproductive for inhalation. Once the size is selected, the material is treated with water by immersion in a bath, with gentle agitation, then the material is cast through a 3 or 4 mm diameter mesh and washed with water ensuring that there are no remaining Small or powdered particles, drained and dried by a stream of air first and then in an oven or dryer at the appropriate temperature (between 50 ° C and 105 ° C).
    Also part of the object of the invention is the mixing of the expanded perlite (washed, selected and dried) with liquids composed of some of the following components: on the one hand glycerin and on the other propylene glycol or polyethylene glycol-400, in proportions between 1: 10 and 10: 1, and adding to the mixture one or several aromas in final percentage between 0.05 and 10%, resulting in a mixture that can be smoked by heating in a water pipe.
    In a preferred embodiment, between 8 and 10 grams of expanded perlite (washed, selected and dried) are mixed with 32-36 grams of water pipe liquid, the mixture is prepared directly in a canister or jar of 100 to 125 ml of volume, adding both components properly weighed or dosed, covering and sealing the container and subjecting the assembly to slight stirring by inversion.
