Linear Alkyl Sulfonate (LAS)

Readily biodegradable form of alkylbenzene sulfonate surfactant.

This is the workhorse of the detergent industry, with sodium dodecylbenzene sulfonate being the most important single type. It is distinguished from an earlier form of alkylbenzene sulfonate, termed ABS, but is a linear (straight chain) structure, which provides its good biodegradation properties.

All LAS surfactants are anionic and high sudsing, but their sudsing may be controlled by formulation.
