Sodium Benzenesulfonate

  • Anionic surfactants
  • CAS 68081-81-2
  • IUPAC: Sodium (C10-16) benzenesulfonate

Mild skin and eye irritant at concentrate strength. At consumer product concentrations (≤10%), typically classified with H315 skin irritation and H319 eye irritation, though many formulations fall below classification thresholds. Not classified as a respiratory sensitizer or carcinogen. Prolonged or repeated skin contact with concentrated solutions can cause dermatitis.

Sodium (C10-16) benzenesulfonate is a linear alkylbenzene sulfonate (LAS) anionic surfactant used in a wide range of cleaning products. It is one of the most common surfactants in consumer and automotive cleaning formulations, providing soil emulsification, wetting, and foaming properties. **Why it matters in detailing products**: LAS surfactants are the primary cleaning agent in many carpet cleaners, all-purpose cleaners, and degreasers. They are effective soil lifters but can leave surfactant residue in carpet fibers if over-applied or insufficiently extracted — a key factor in the resoiling behavior that separates good carpet cleaners from poor ones. **SDS alert**: Check Section 3 for CAS 68081-81-2. At concentrations above 10%, expect H315 and H319 classifications. Below 5%, most formulations fall under classification thresholds. ## Regulatory status - Not CA Prop 65 listed - Listed on TSCA inventory; no specific use restrictions for consumer cleaning products in the US - EU CLP classification: H318 (serious eye damage) at concentrate; H315 (skin irritation), H319 (eye irritation) at typical use concentrations
