Sodium Di(2-Ethylhexyl) Sulfosuccinate

  • Anionic surfactants
  • CAS 577-11-7
  • IUPAC: Sodium 1,4-bis(2-ethylhexoxy)-1,4-dioxobutane-2-sulfonate

Sodium Di(2-Ethylhexyl) Sulfosuccinate (CAS 577-11-7) appears in 1 of the 1,812 car-care products CarCareTruth tracks (as of June 2026). It is readily biodegradable.

Classified as Skin Sensitizer Cat 1A (H317) at ingredient level. At concentrations below 3% in consumer products, skin sensitization risk is low for most users, but repeated contact may sensitize susceptible individuals. Identified as a surfactant ingredient in several Meguiar's G-series SDS documents.

Sodium di(2-ethylhexyl) sulfosuccinate (also known as docusate sodium, CAS 577-11-7) is an anionic surfactant used as a wetting agent and emulsifier. It lowers surface tension, enabling uniform spreading of vinyl and rubber dressing formulations on hydrophobic surfaces.

At the sub-3% concentrations typical in consumer vinyl conditioners, the primary hazard is skin sensitization (H317 at GHS Cat 1A level), which is carried through to the product mixture classification. Aquatic toxicity has been documented; the compound is readily biodegradable under aerobic conditions.
