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

No inhibition of the biodegradation process was recorded in the toxicity control at a concentration of 100 mg/L in a standard biodegradation study according to OECD 301F (GLP). Thus, in accordance with the Guidance on Information Requirements and Chemical Safety Assessment Chapter R.7b; Endpoint specific guidance (ECHA, 2017) a NOEC (14 d) of ≥ 100 mg/L was derived.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
100 mg/L

Additional information

The toxicity of the test substance to microorganisms was determined in a ready biodegradability study conducted according to OECD Guideline 301F (1994). A nominal concentration of 100 mg/L test substance plus 100 mg/L aniline (positive control) was incubated with activated sludge for 28 days under aerobic conditions, alongside an inoculum blank and a positive control. Oxygen consumption was measured electrolytically daily. The test substance is not toxic to microorganisms. This study is considered to be reliable without restriction (Klimisch 1).
