Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Ecotoxicological information

Short-term toxicity to aquatic invertebrates

Administrative data

short-term toxicity to aquatic invertebrates
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is unlikely to cross biological membranes, hence indicating that aquatic toxicity is unlikely to occur
Justification for type of information:
According to REACH Regulation Annex XI, a registrant may adapt the standard testing regime laid down in REACH Anneces VII-X in accordance with the general rules set out in Section 1 of this Annex. Following para 2 of Annex XI, testing for a specific endpoint may be omitted, if it is technically not possible to conduct the study as a consequence of specific properties of the specific substance. This implies experimental testing of highly reactive or unstable substances and/or if handling and mixing of the substance may cause danger of fire or explosion. Tetracene is a substance exhibiting very high reactivity and explosive properties. According to criteria of EU Commission Regulation (EU) No.286/2011 (CLP), tetracene has to be classified as an unstable explosive (H200). Due to these properties of the test item and in accordance with REACH Annex XI, it is not possible to conduct an experimental study on the endpoint 'toxicity to aquatic invertebrates'.
