Description of key information

Readily biodegradable according to OECD criteria: 100% after 28 days based on CO2 evolution (OECD 301 B).

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

One GLP study assessing biodegradation of the C12-isoAS Na (CAS 94200-74-5), performed according to OECD guideline 301 B is available (Brunswik-Titze 2003). Activated, non-adapted domestic sludge was used as inoculum. The substance was tested in a concentration of 8.12 mg/L (as organic carbon) and CO2 evolution was measured. In result, 100% of biodegradation was observed after 28-day test period, passing 10-day window. It can be concluded that the substance is readily biodegradable.
