Description of key information
The performance of a test for long-term toxicity testing on invertebrates (preferred species Daphnia) was considered not scientifically justified.
REACH Regulation (EC) No 1907/2006, Annex IX, Sect. 9.1.5, 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 test(s) depends on the results of the chemical safety assessment."
In accordance with column 2 of REACH Annex IX, long-term toxicity testing on invertebrates (preferred species Daphnia) was not conducted since the test substance has a low water solubility and it is hydrolytically unstable and ready biodegradable. Due to the unstable nature of the test substance, it can be assumed that upon contact with water and organic matter, the test item undergoes rapid degradation resulting in the formation of respective degradation products. Therefore, aquatic toxicity is unlikely to occrur. Thus, the CSR does not show a need for an additional long-term aquatic test.

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.
