What Is Oleth-10?

Oleth-10 is a form of non-irritating fatty alcohol that functions as a texture enhancer and cleansing agent. It is widely used as an emulsifier in water + oil cosmetics.

In general, oleth ingredients clean skin by helping water mix with oil and dirt so they can be whisked away. Oleth-10 can also be used in shampoos.

In 2012, the Cosmetic Ingredient Review Expert Panel concluded that Oleth-10 is safe as when formulated to be nonirritating (their report looked at products containing amounts of 14% and lower).
