What Ceteareth-30 is & what it does

Ceteareth-30 is an ethoxylated fatty alcohol (cetearyl alcohol reacted with about 30 units of ethylene oxide), which makes it a nonionic surfactant. In formulas it works as an emulsifier and solubilizer, helping blend oil and water phases and dissolve oily ingredients into water-based products. It is not a UV filter and appears in a small number of products.
