About Laureth-21

Laureth-21 is the polyethylene glycol ether of lauryl alcohol, with n averaging 21.[1] The number 21 at the end of the name refers to the average number of added ethylene oxide units. It changes the balance between the water-loving and oil-loving portions, resulting in differences in cleansing power, emulsifying ability, and feel. In cosmetics, it is used to help sebum and impurities wash away with water and to lower surface tension so ingredients wet, mix, and spread evenly.[2]
