The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
