PURPOSE: To obtain a bath agent containing an ionic enzyme as an active component and extremely good for health, by putting crushed green tuff in an inner bag made of double-layered cotton cloth and covering the bag with a mesh nylon cloth.

CONSTITUTION: Green tuff 3 crushed to granules is put into the inner bag made of double-layered cotton cloth 2, the cotton cloth bag 2 is covered with a mesh nylon cloth, and the circumference edge of the hylon cloth is stitched by feather- stitch to obtain the objective ionic enzymatic bath agent. The escape of element coarser than 1,000 mesh can be prevented by the use of double-layered cotton cloth as the inner bag and, furthermore, the agent is soluble in water with little generation of precipitate without cousing the clouding of water and has improved absorbability. The human filth, fur and decayed smell can be adsorbed by the hydrogen ion exchange activity of the green tuff. The durability of the action is prolonged by the cotton cloth and the nylon net is effective to prevent the breakage of the cotton cloth during use. An ionic enzymatic bath can be prepared simply by immersing the bag in bath water and the effect of a bag (containing 200g of green tuff) lasts for about 100 days.
