Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to better understand the foregoing, drawings are provided wherein, schematically and solely by way of non-limiting example, a practical case of embodiment is represented.

[0021] FIG. 1 is a graph showing the weight loss percentage over time of a composition according to the present invention and a comparison composition.

DESCRIPTION OF A PREFERRED EMBODIMENT

[0022] The composition for diffusing volatile substances according to the present invention comprises wax and solid material, for example, solid particles.

[0023] Said solid material is preferably ethylene-vinyl acetate (EVA) and has a capacity to absorb more volatile substances than wax, such as for example, twice the volatile substances absorption capacity than that of wax, considering the same volume.

[0024] In the composition according to the present invention, the volatile substances may be contained in the wax and in the solid material, or only in the solid material, as desired. In the event that the wax and solid material include volatile substances, they can be different from each other to provide different features.

[0025] An example of the composition according to the present invention and a comparative example of a conventional composition are described below.

[0026] In this example, the composition was a 11 g block of wax, with 5% of volatile substances, that is, 0.55 g.

[0027] It was evaluated how much solid material (EVA) would be needed to double the amount of volatile substances in the same volume as the original block. After an initial estimate and considering that said solid material is capable of absorbing 20% of volatile substances, a mixture is obtained as a result (considering that both materials had a similar density) where approximately 65% by weight was wax impregnated with volatile substances and 35% by weight was EVA impregnated with volatile substances, obtaining twice the amount of volatile substances for the same occupied volume.

[0028] A comparison composition was also made with only wax impregnated with volatile substances and a mixture with the percentages mentioned above. A heated device was used and the two products were compared. After 24 hours, the results are shown in the graph of FIG. 1 and in the attached table.

TABLE-US-00001 Composition Comparison according to composition the invention Initial Weight (grams) 11.1 10.8 Evaporated volatile substances (grams) 0.65 1.13 T (° C.) 83 83

[0029] Based on said graph and said table, the following conclusions can be drawn: [0030] The amount of evaporated volatile substances is much greater for the same evaporation time and, therefore, user perception is also greater. [0031] After 5 hours, the amount of evaporated volatile substances in the wax alone is practically level, while in the example according to the present invention, the evaporated amount continues to increase beyond 8 hours, the solid material helping to slow evaporation. [0032] As seen in the final evaporation, not only are there more volatile substances at the beginning, but the composition according to the invention is capable of evaporating the volatile substances an additional 74% after 24 hours.

[0033] Despite the fact that reference has been made to a specific embodiment of the invention, it is evident for a person skilled in the art that the described composition is susceptible to numerous variations and modifications, and that all the aforementioned details may be replaced by other, technically equivalent ones, without falling outside the scope of protection defined by the attached claims.
