Alpha Olefin Sulfonate
What is Alpha Olefin Sulfonate?
Alpha Olefin Sulfonate is a synthetic anionic surfactant made by sulfonating alpha olefins, which are straight-chain hydrocarbons typically sourced from petroleum feedstocks. It commonly features C14-C16 carbon chain lengths and exists as sodium, ammonium, or other salts. In cosmetics, it serves as a key ingredient in rinse-off cleansing products such as shampoos, body washes, facial cleansers, and toothpastes. Its primary function involves reducing water's surface tension to emulsify oils, lift away dirt, sebum, and impurities from skin and hair surfaces, while generating substantial lather for a satisfying cleansing experience. This surfactant offers good solubility and stability across various pH levels, making it versatile for formulation in personal care items.
