Ceteth-20
Ceteth-20Barrier
A nonionic surfactant used to emulsify oil and water and to solubilize oily ingredients.
What it does
Ceteth-20 is cetyl alcohol reacted with ethylene oxide, which makes it part water-loving and part oil-loving. It blends oil and water into a stable emulsion and can dissolve small amounts of oily ingredients into a water base, so it is used as an emulsifier and solubilizer. It is a formulation ingredient rather than a skin active.
