About

A nonionic surfactant from ethoxylated mixed-chain alcohols, used to solubilize and emulsify cosmetic formulations.

C12-15 Pareth-5 and related variants are nonionic surfactants from the ethoxylation of mixed C12-C16 fatty alcohols, functioning as solubilizing and cleansing agents in water-based cosmetic formulations. These ingredients are permitted under EU Regulation 1223/2009 without specific restrictions, though 1,4-dioxane must be removed to trace levels. Typical use levels range from 0.1% to 5%.
