Description of key information

Amides, C16-C18 (even), N,N'-ethylenebis exhibited no toxicity within the range of water solubility (EC50>0.053 mg/L, limit of solubility)

Key value for chemical safety assessment

Additional information

The toxicity of Amides, C16-C18 (even), N,N'-ethylenebis to the freshwater algae Pseudokircheneriella subcapitata was investigated in one study from the Japanese Ministry of Environment (MOE, 2002). This study followed the OECD Guideline No. 201: Algae, Growth Inhibition Test (1984). The results from this test show that after 72 hours exposure to Amides, C16-C18 (even), N,N'-ethylenebis, no effects on growth rate of Pseudokircheneriella subcapitata were observed, up to the highest attainable concentration (0.053 mg/L, limit of solubility). Therefore, the 72h-EC50 was greater than 0.053 mg/L and no toxicity within the range of water solubility was reported.
