Description of key information

REACH Regulation (EC) No 1907/2006, Annex IX, Sect. 9.1, Col. 2, states as follows: 
“9.1.: Long-term toxicity testing shall be proposed by the registrant if the chemical safety assessment according to Annex I indicates the need to investigate further the effects on aquatic organisms. The choice of the appropriate tests(s) depends on the results of the chemical safety assessment."
A study assessing the long-term toxicity of the test item cyclohexylidenebis[tert-butyl] peroxide towards aquatic invertebrates (Daphnia sp.) according to OECD 211 guideline is currently not available. The studies assessing the short-term toxicity of the test item towards fish, aquatic invertebrates (Daphnia sp.) and alage clearly show no adverse effects up to the test item's water solubility. In order to support this finding, a study assessing the long-term toxicity towards aquatic invertebrates (Daphnia sp.) according to OECD 211 guideline will be conducted, since the risk assesment (see PNEC derivation in IUCLID section 6) indicates the nedd to investigate further the effects on aquatic organisms. The study assessing the long-term toxicity of the test item towards aquatic invertebrates (Daphnia sp.) will be ordered. As soon as the study report is available the dossier and the Chemical Safety Report (CSR) will be upadated accordingly.
