Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

For Blankophor TP 1480 (EC 934 -958 -4) no tests are available. Therefore studies conducted with the structural analogue CAS 16470 -24 -9 are used to cover the aquatic toxicity endpoints. For CAS 16470 -24 -9 short-term studies on freshwater species of three trophic levels (fish, invertebrates and algae) are available. In addition a chronic study for invertebrates (Daphnia magna) is conducted with CAS 16470 -24 -9. Effects on microorganisms were tested on activated domestic sludge.

All available studies followed current guidelines (OECD and EU-guidelines) and were conducted in accordance with GLP requirements.

The acute tests resulted in no effects up to the highest test concentrations and thus the LC/EC50-values were above 100 mg/L (in detail: LC­50(fish, 96 h) > 859 mg/L, EC50(daphnids, 48 h) > 113 mg/L and EC50(algae, 72 h) > 1000 mg/L). For microorganims an EC50(3 h) > 10000 mg/L was reported.

The chronic test on daphnids resulted in NOEC (21 d) based on reproduction of 10 mg/L. The LOEC (21 d) was determined to be 31.6 mg/L.

Concluding from the results obtained with the read-across substance CAS 16470 -24 -9 for Blankophor TP 1480 no adverse effects on aquatic organisms are expected.
