PROBLEM TO BE SOLVED: To eliminate a sulfate radical (SO 4 −− ) residual obstacle caused by a sulfate-based mineral solution, and to obtain a sulfate radical obtained by natural plant organic acid for leaching a mineral component of a natural granodiorite-based mineral. It is an object of the present invention to provide a plant skin juice composition containing no natural mineral ions. SOLUTION: The present invention is by immersing a fine granite diorite biotite, a natural granodiorite mineral, in pineapple peel juice, coconut palm juice juice, and citrus peel juice of a vegetable organic acid. In addition, a natural mineral ion-containing plant skin juice composition containing no sulfate radicals could be obtained. |
