Additional information
Conclusion on classification
Based on all the available ecotoxicological data for invertebrates, fish and algae, TBBPA should be classified and labelled as N; R50/53 in accordance with Directive 67/548/EEC and as Aquatic Acute Category 1 and Aquatic Chronic Category 1 in accordance with Regulation (EC) No. 1272/2008.
The key values used for chemical safety assessment were as follows:
- Short term toxicity to fish: LC50 = 1.1 mg/L (Oncorhynchus mykiss)
- Long term toxicity to fish: NOEC = 0.16 mg/L (Pimephales promelas)
- Short term toxicity to invertebrates: LC50 >1.8 mg/L (Daphnia magna)
- Long term toxicity to invertebrates: freshwater NOEC = 0.38 mg/L (Daphnia magna); marine water NOEC = 0.017 mg/L (Mytilus edulis)
- Toxicity to algae: NOEC = 5.6 mg/L (Pseudokirchneriella subcapitata)
- The substance is not readily biodegradable
- The log Kow is 5.9 at 25 °C
Furthermore, TBBPA is officially classified as N; R50/53 on Annex I of Directive 67/548/EEC and as Aquatic Acute Category 1 and Aquatic Chronic Category 1 on Annex VI of Regulation (EC) No. 1272/2008.
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.
