Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Daphnia magna was exposed under static conditions for 48 hours to one concentration of HDI oligomers, iminooxadiazindione. Analysis of the immobilisation rates showed an EL0 of ≥100 mg/L.
The results are expressed in terms of effective loadings (EL) at 24h and 48h. Considering the heterogeneous composition of the test item, Water Accommodated Fractions WAF's) were tested. The results of the DOC determinations reflect a rough impression only of exposure
conditions over time. No informations are available on a potential correlation between effective loadings and measured DOC values. Up to the waten solubility of the test item under exposure conditions no toxic effects were determined.

Key value for chemical safety assessment

Fresh water invertebrates

Fresh water invertebrates
Effect concentration:
100 mg/L

Additional information

The key value should read ≥ 100 mg/L as no EC50 could be determined at the limit test concentration of 100 mg/L.
