Description of key information

No toxic effects to aquatic invertebrates up to the limit of water solubility (< 0.15 mg/L).

Key value for chemical safety assessment

Additional information

Experimental data on the short-term toxicity of Fatty acids, C16-18 and C18-unsatd., hexaesters with dipentaerythritol (CAS 68604-38-6) are not available. According to Regulation (EC) No 1907/2006, column 2, 9.1.1. short-term toxicity testing with aquatic invertebrates does not need to be conducted if a long-term aquatic toxicity study on invertebrates is available. The testing according to OECD211 revealed no chronic toxicity of the substance to Daphnia magna (Caduff, 2013). The substance caused no mortality of adult specimen or juvenils (NOEC (21d) ≥ 100 mg/L). Thus acute toxic effects of Fatty acids, C16-18 and C18-unsatd., hexaesters with dipentaerythritol (CAS 68604-38-6) to aquatic invertebrates are not expected up to the limit of water solubility (WS<0.15 mg/L). Therefore short-term toxicity testing on aquatic invertebrates is not proposed.
