Sodium Laureth Sulfate
Excipient (pharmacologically inactive substance)
What is it?
Sodium laureth sulfate is a surfactant and detergent found in many cosmetic and personal care products, such as soaps, shampoos and toothpaste. Sodium laureth sulfate is not to be confused with sodium lauryl sulfate. There is concern that sodium laureth sulphate may be contaminated with potentially toxic manufacturing impurities such as 1,4-dioxane. The state of California has banned 1,4-dioxane as a potential carcinogen.
