Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
short-term toxicity to aquatic invertebrates
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because a long-term aquatic toxicity study on invertebrates is available
Endpoint:
short-term toxicity to aquatic invertebrates
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is highly insoluble in water, hence indicating that aquatic toxicity is unlikely to occur

Description of key information

The registration substance is practically insoluble and has a negligible vapour pressure. As an insoluble solid the potential to cross biological membranes is negligible.


In addition a long-term chronic study with daphnia magna performed with Pigment Orange 34 is available showing no toxicity well above the solubility limit of the substance.

Key value for chemical safety assessment
