Shower gel or shower cream, also known as bodywash, is the general term for liquid soap, which is used for cleaning the body. In the United States, it is usually marketed as body wash. Most commercial shower gels are scented and do not contain any saponified oil, instead being products of petroleum. Shower gel/bodywash is an emulsion of water and detergent base with added fragrance used as a skin cleansing agent in the shower or bath. It has advantages over soap because it is less irritating to the skin, lathers better in hard water areas and does not leave a mineral residue on the skin or in the bathtub after usage.
