Linear Alkyl Benzene Sulfonic Acid (LABSA)

Linear Alkyl Benzene Sulfonic Acid (LABSA) — chemical formula C₆H₅CₙH₂ₙ₊₁ (n = 10–16) — is a highly active anionic surfactant and one of the most widely used raw materials in the detergent and cleaning product industry. It appears as a brown to dark amber viscous liquid with strong surface-active properties, making it a key ingredient in household, industrial, and institutional cleaners.

Derived from linear alkyl benzene (LAB) through sulfonation, LABSA combines excellent emulsifying, wetting, and foaming capabilities with strong detergency power even in hard water conditions. Its biodegradable nature makes it an environmentally friendly surfactant choice compared to older branched-chain alternatives.
