Olefin Sulfonate
What is Olefin Sulfonate?
Olefin sulfonate refers to salts like sodium or ammonium C14-16 olefin sulfonate, created by sulfonating alpha-olefins from petroleum sources with 14 to 18 carbon atoms. This gives it a chemical structure suited as an anionic surfactant in cosmetics. It appears mainly in rinse-off items such as shampoos, body washes, hand soaps, and facial cleansers. By decreasing water's surface tension, it emulsifies oils, lifts away dirt and residues from skin and hair, and disperses them in rinse water. It also builds dense, persistent lather that feels luxurious during washing. Its resistance to hard water minerals prevents reduced performance, unlike some other cleansers. Formulators value its blend of power and relative gentleness among surfactants.
