Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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.

Additional information

One study (2007, Archroma) was performed on analogue substance 4 for acute toxicity to Daphnia Magna following OECD 202, Immobilisation test.

A screening test with nominal concentrations of 100, 10 and 1 mg/1, respectively, was performed.

At all nominal test concentrations no significant effects ( <10 % immobilization) were observed after 24 and 48 h of exposure.

Therefore, the EC0, 48h and the EC50, 48h were found to be ≥ 100 mg/l.

Based on the read across considerations same results apply to target substance and the substance sccording to Directive 93/21/EEC (adaptation to Directive 67/548/EEC) is 'not toxic' to Daphnia magna after an exposure period of 48 hours.
