All tests demonstrated that the acute EC50 and LC50 values are > 100 mg B-TEGME/L and hence, no classification and labelling is needed.
In accordance with column 2 of REACH Annex IX (section 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".
Chronic tests for further refinement of the risk assessment are not required since the risk is already appropriately characterized by the above for following reasons: B-TEGME (1) will not be directly applied to the aquatic environment, (2) is readily biodegradable, (3) hydrolyses quickly and (4) has a low potential for bioaccumulation, i. e., the log Pow is << 3 . Therefore, it is very unlikely that B-TEGME will be transported to the aquatic environment via STP. Furthermore, it can be assumed that the potential hazard from B-TEGME is low since B-TEGME is not toxic to aquatic organisms (freshwater). Based on these characteristics, B-TEGME is not expected to cause adverse effects on aquatic organisms and hence long-term testing is not needed.
