Cosmetics are used to help the skin’s native function work normally with the aim of keeping and recovering healthy, beautiful skin and hair. Cosmetics have a variety of roles; their basic purposes include washing, wiping clean, and anti-dryness, anti-ultraviolet, antioxidation and stimulation functions. The purpose of bodily cleansing is to remove dirt on skin and hair and keep a body hygienic. Cosmetics can be classified in various ways, such as by their purpose and form, and body cleansing agents can be categorized by the body parts to which they are applied, such as cleansing agents for skin, the body, and hair. Skin cleansing agents, which are used to wash facial skin, remove metabolites produced by physiological actions of the skin, such as sebum, stratum corneum scales, oxidative degradation agents of sebum, sweat residue, dirt in the air, microorganisms, and makeup residue from the skin’s surface. Like skin cleansing agents, body cleansing agents are used to wash a large region of the body. Hair cleansing agents remove dirt on the scalp and hair and keep them clean. Although the kinds of dirt on the scalp and hair are similar to those on the skin, residues of hair care agents are also dirt to be removed. What is needed in common for these cleansing agents includes detergency, low stimulative effect on the skin, and foaming property, and these attributes mainly depend on the properties of surfactants. The evolution of cleansing agents is due largely to the evolution of surfactants. Looking back on the historical background of cleansing agents and the basis of cleansing, this article describes the kinds and ingredients of cleansing agents and the effects of cleansing agents by classifying the agents by the body parts they wash and focusing on surfactants.
