PROBLEM TO BE SOLVED: To solve the problem of a mixed oil conventionally used in an aroma therapy in which: according to a therapeutic purpose, usually several types of essential oils are blended to maximize the therapeutic effect by a complex/synergetic effect of each type of aroma, however, volatilization rates range from high to low depending on the type, therefore, with the mixed oil, due to the difference in the volatilization rate, the aroma changes significantly in a short time from an early stage of a therapy, lowering the effect of the therapy.SOLUTION: Essential oil is confined and adsorbed in particles of a porous inorganic oxide whose main component is silica having continuous pores in nanoscale in a high volume ratio. Thus, long-lasting effect of generation of aroma is improved. Furthermore, according to the volatilization rate, a particle size of the porous inorganic oxide is adjusted to improve the long-lasting effect and stability of strength of aroma to be generated for the various mixed essential oils. |
