Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

LC50 (14 d) > 3000 mg/kg soil dw

Key value for chemical safety assessment

Short-term EC50 or LC50 for soil macroorganisms:
3 000 mg/kg soil dw

Additional information

A test was performed on the substance under registration according to OECD 2017 with Eisenia foetida and LC50 > 3000 mg/Kg dry weight. The original report is not available.

A second test was performed on the analogous substance 3a-MSA according to OECD 2017 and LC50 > 3000 mg/Kg dry weight.

Justification for Read Across is given in Section 13 of IUCLID. Both substances are tetrasulphonated sodium salts. The substance's constituent is less polar, less reactive and makes the molecule slightly less soluble compared to the similar substance derivative. The latter can therefore considered as a representative conservative analogous for the soil toxicity because of the higher bioavailability and higher reactivity with organic substrates.

No concern for soil toxicity is then arisen by the presented acute studies on the substance under registration.
