- Q：Why do some soap products contain tetrasodium etidronate? A： etrasodium etidronate is an ingredient contained in solid soap products of Matsuyama as a sequestering agent. Soap contains water, which is one of the raw materials, as well as metallic ions (not metals themselves but metallic ions) introduced by the equipment used for making soap. Metallic ions gradually degrade the color or smell of soap over the course of time. The ingredient added to prevent this degradation is tetrasodium etidronate.
