About this ingredient
Ceteth-20 is a nonionic surfactant, an ethoxylated cetyl alcohol with a chain of twenty ethylene-oxide units. INCI: Ceteth-20. In a formula it works as an emulsifier and solubilizer: it binds oil and water, helps dissolve poorly soluble components, and stabilizes the cream. It is a functional component, not a skincare active. It is used in creams, emulsions, and cleansers. Pregnancy safety. Systemic absorption through intact skin is low and there is no evidence of harm. It can be used during pregnancy and lactation. Tolerance. Irritation and allergen potential are low. As with ethoxylated raw materials, the standard caveat about 1,4-dioxane removal in manufacturing applies.
