Here's a concise explanation of Dodecylbenzenesulphonic acid (DDBSA/DBSA):
Dodecylbenzenesulphonic acid (C₁₈H₃₀O₃S) is a dark, viscous, strong organic acid and key anionic surfactant. Its structure combines a hydrophobic 12-carbon chain (dodecyl) attached to a benzene ring with a hydrophilic sulfonic acid group (-SO₃H).
Key Properties:
Strong acid (corrosive)
Excellent surfactant (lowers surface tension)
Hygroscopic
Primary Uses:
Main use: Raw material for Linear Alkylbenzene Sulfonate (LABS/LAS), the dominant surfactant in liquid detergents, soaps, and cleaners.
Industrial cleaner emulsifier.
Acid catalyst in chemical synthesis.
Handle with care due to corrosiveness. Its detergent derivatives require proper wastewater treatment.
