Dodecylbenzenesulfonic acid

Dodecylbenzenesulfonic acid (CAS 27176-87-0 ), commonly known as DDBSA or laurylbenzenesulfonic acid, is a high-performance anionic surfactant and acid catalyst used across cleaning, agricultural, and industrial processing applications. It functions primarily as a surfactant precursor, emulsifier, and pH-active ingredient in formulated products. In household and industrial cleaning formulations, it is neutralized on-site to produce linear alkylbenzene sulfonate. This derivative serves as the active detergent component in liquid dish soaps, hard surface cleaners, and degreasers. Agricultural formulations use it as an emulsifier and dispersant in pesticide and herbicide concentrates. These applications improve active ingredient delivery and tank-mix stability. Textile and leather processors apply it as a wetting and penetration agent during dyeing, tanning, and finishing operations. In industrial contexts, it also acts as an acid catalyst in alkylation and esterification processes. The product is supplied as a viscous liquid, typically at 96–97% active content for industrial use. Technical grade is the predominant market form, with hard and soft acid variants available depending on the linear or branched alkyl chain composition. Drum and IBC packaging are standard for most orders. Bulk tanker supply is also available for high-volume buyers requiring consistent delivery. This chemical remains a foundational component for manufacturers seeking reliable performance in surfactant synthesis. Contact us for supply of Dodecylbenzenesulfonic acid Request Quote
