What is alpha-olefin sulfonate?

Alpha-olefin sulfonate is a type of anionic surfactant that is widely used in the production of household and personal care products. It is made by the sulfonation of alpha-olefins, which are olefins or alkenes with a double bond at the primary carbon atom. The resulting compound is typically a mixture of linear and branched-chain alkene sulfonates.

Alpha-olefin sulfonate is known for its excellent foaming and cleaning properties, making it a popular ingredient in shampoos, liquid soaps, laundry detergents, and other cleaning products. It is also used in oilfield chemicals, agricultural formulations, and industrial applications.

The production of alpha-olefin sulfonate is typically carried out by sulfonation of alpha-olefins using sulfur trioxide or oleum. The resulting product is a mixture of sulfonates, which are then neutralized with either sodium hydroxide or amines to produce the final product.

Overall, alpha-olefin sulfonate is a versatile, effective, and widely-used surfactant that plays an important role in many different industries.
