Linear alkylbenzene sulfonates appear as small, deliquescent, needle-like crystals or large, flaky crystals. They are soluble in water and alcohols; slightly soluble in benzene; and insoluble in diethyl ether and carbon disulfide. They can react with active metals (including iron and aluminum) and many less reactive metals, dissolving the metals and releasing hydrogen gas and/or toxic gases. Like other acids, these substances can initiate polymerization reactions of certain organic compounds. They react with cyanide salts and compounds to release gaseous hydrogen cyanide. They are used in the manufacture of other chemicals. They react with air and water to produce phenol, resorcinol, and other organic compounds, and are used as catalysts.

Applications
Alkylbenzene sulfonic acid is mainly used as a surfactant in cleaning products and detergents, and also serves as an emulsifier in pesticide formulations. It is a key active component in synthetic detergent products and a fundamental raw material for manufacturing synthetic laundry powders and a variety of synthetic liquid detergents.
