Bath salts are water-soluble, pulverised minerals that are added to water to be used for bathing. They are said to improve cleaning, enhance the enjoyment of bathing, and serve as a vehicle for cosmetic agents.

Bath salts have been developed which mimic the properties of natural mineral baths or hot springs. Fragrances and colors are often added to bath salts; the fragrances are used to increase users’ enjoyment of the bathing experience.
