The environmental classification of Bis-(N,N-dimethylaminoethoxyethyl)-methylamine (LE30) is currently not harmonized according to the CLP Regulation (EC) 1272/2008. Based on available acute aquatic toxicity data, the lowest valid effect concentration for freshwater aquatic organisms is 18 mg/L (ErC50 for algae). Based on the available acute data, the substance should not be classified for acute toxicity following Annex I, table 4.1.0 (a) of the CLP regulation (there are no acute values ≤ 1 mg/L). In the algal growth inhibition study, the NOErC for algae was 2.9 mg/L. No other long-term values are available, therefore the substance's classification for chronic toxicity should be determined based on the acute toxicity values, following Annex I, table 4.1.0 b (iii) of the CLP Regulation. Taking into account the acute toxicity data as well as the fact that the substance is not rapidly degradable and its log Kow is < 4, the substance should be classified as Aquatic Chronic 3 under the CLP Regulation.
