Description of key information

NOEC (3 h) of ≥ 1000 mg/L for activated sludge microorganisms (OECD 209).

Key value for chemical safety assessment

Additional information

One study is available investigating the effects of dodecyl oleate (CAS 36078-10-1) to activated sludge microorganisms (Brunswik-Titze, 2012). The study was performed according to OECD 209 using activated sludge from a predominantly domestic sewage treatment plant. A limit test with a nominal concentration of 1000 mg/L was performed for 3 h. The respiration rate of activated sludge microorganisms was not inhibited resulting in a NOEC (3 h) of ≥ 1000 mg/L. Thus, it can be concluded that no toxicological effects of dodecyl oleate on microorganisms are expected.
