Sodium Dodecylbenzenesulfonate
Sodium Dodecylbenzenesulfonate (CAS: 25155-30-0) is a classic anionic surfactant featuring a C12 alkyl chain attached to a benzenesulfonate head group, combining strong detergency with excellent water solubility. This white to pale-yellow powder or flake is a cornerstone of household and industrial cleaning, providing powerful grease cutting, wetting, and foaming performance in laundry powders, dishwashing liquids, and all-purpose cleaners. Its branched or linear alkyl variants balance cost and biodegradability considerations across formulations. Industrial applications include emulsion polymerization as a primary emulsifier, textile scouring, and as a wetting agent in agricultural spray formulations. The compound’s stability in alkaline conditions and compatibility with builders and bleaches support its use in heavy-duty detergent systems. With decades of proven performance and economical production, sodium dodecylbenzenesulfonate remains a fundamental surfactant in global cleaning product manufacturing.
– Laundry Detergents: Used as a primary active surfactant in washing powders and liquids providing strong soil removal and grease emulsification.
– Dishwashing and Hard-Surface Cleaners: Serves in manual dishwashing liquids and degreasers for effective cleaning and lasting suds.
– Emulsion Polymerization: Applied as a primary emulsifier in latex production for paints, adhesives, and carpet backing.
– Textile and Agriculture: Employed as a scouring agent in textile processing and as a wetting agent in pesticide spray formulations.
