sodium dodecylbenzenesulfonates are a member of the linear alkylbenzenesulfonates, meaning that the dodecyl group (C12H25) is unbranched. This dodecyl chain is attached at the 4-position of the benzenesulfonate group. Linear dodecyl-4-benzenesulfonate anions can exist in six isomers (ignoring optical isomers), depending on the carbon of the dodecyl group that is attached to the benzene ring. The isomer shown below left is 4-(5-dodecyl)benzenesulfonate (4 indicating the position of the benzene ring, 5 indicating the position on the dodecane chain). Branched isomers, e.g. those derived from tetramerized propylene, are also known (below right) but are not as widely used because they biodegrade too slowly.

Widely used in detergent industry,forming agglomerated detergent production,oil exploitation,
chemical fertilizer additives,cement industrial cleaning agent and air-entraining agent, textile and dyeing agent,printing and filter agent in silk.

It can be used directly to formulate detergents for household and industry use. Because of its hygroscopicity, please use it immediately after the bag is open.

1). High-efficiency emulsifying agent for the polymerization of pressure sensitive adhersive

2). As raw material for high-grade cleaning agent, eradicator and detergents. 
3). As anti-static additive for textile oils. 
4). As excellent anti-static agent for polyester base materials.
