Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- toxicity to bees: chronic oral
- Data waiving:
- exposure considerations
- Justification for data waiving:
- the study does not need to be conducted because direct and indirect exposure of the soil compartment is unlikely
- Justification for type of information:
- The substance is not supposed to be directly applied to soil. Based on the PC properties of the substance (extremely low solubility in water and octanol), a low adsorption potential is indicated. Therefore, binding to sewage sludge is unlikely and as a consequence a transfer to the soil compartment is not expected. Therefore it can be assumed that there is no direct and indirect exposure to the environment. Furthermore, due to their physico-chemical properties and very low (bio)solubility the Diazopyrazolone Pigments are considered to be not bioavailable. This is supported by the absence of toxicity in long term experiments with earthworms and sediment worms.
- Endpoint:
- toxicity to bees: acute oral
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- a short-term study does not need to be conducted because an appropriate long-term toxicity study on terrestrial organisms is available
- Justification for type of information:
- there is a long-term study available (OECD 222)

Description of key information
Direct and indirect exposure of the soil compartment is unlikely. In addition, there is no indication for any toxicity of the test substance, neither in tests on earthworms (Eisenia fetida) and sediment worms nor in tests on aquatic organisms of all trophic levels (acute and chronic). Furthermore, the outcome of the CSA indicates that the available terrestrial toxicity tests are appropriate to cover the information requirements. Therefore no further terrestric studies are necessary.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
