Looking at the formation process of weathered coral fine grains, first, weathered coral gravel deposited on the seabed is mined to remove impurities. Then, after passing through the steps of classification of coral-only particles, washing with fresh water, and drying, unfired fine particles are sterilized at 100 to 250 ° C. On the other hand, in the case of fired fine particles, firing is performed at 250 to 500 ° C., and finally, both are finely pulverized. The diameter of the coral fine particles used in the present invention is 5.5 to 16 μm and is sterilized at 110 ° C. Even if it is finely ground, weathered coral maintains a pore structure, which is a structural feature of weathered coral, when observed with an electron microscope. This pore structure functions to adsorb moisture including odor generated from body temperature and perspiration.

る。When the water adsorbed on the pore structure receives external energy, that is, the pressure from the foot and the frictional force between the particles generated from the pressure, the water acts on the calcium carbonate in the coral fine particles. As a result, radical negative ions are generated, the oxidized water is alkalized, and odor components and lipids are decomposed by the surface activity of the negative ions, thereby removing odors.

Before walking, put it in your shoes and sprinkle it.
It is the result of comparing the odor and the humidity of the sweating state immediately after walking m. Twenty male and female college students participated as subjects to increase their reliability. As a result, it was found that only the fine coral grains were put in the shoes and almost no smell was felt.
