Sodium Caprylyl Sulfonate

Sodium Caprylyl Sulfonate (sodium octane-1-sulfonate, CAS 5324-84-5) is an anionic sulfonate surfactant used as a foaming agent and soil dispersant in alkaline cleaning and personal care formulations. It is a C8 alkyl sulfonate — shorter chain than the C12-16 lauryl/cetyl sulfonates common in shampoos. Readily biodegradable under aerobic conditions (OECD 301 criteria). Aquatic toxicity is present at ingredient level but the short chain length limits bioaccumulation potential (low log Kow). No Prop 65 listing, no PFAS, no asthmagen classification. GHS classification at ingredient level: mild eye and skin irritant (H319/H315 possible at concentrate), but product-level classification depends on concentration and formulation context.
