Key value for chemical safety assessment

Additional information

One study investigating the toxicity of Fatty acids, C18 unsaturated, trimers, 2-ethylhexyl esters (CAS No. 173832-46-7) to aquatic microorganisms is available. The GLP study was performed under static conditions according to ISO guideline 10712 investigating the cell multiplication inhibition of the substance to Pseudomonas putida (Mead, 1997). A single nominal loading rate of 10,000 mg/L (WAF) was tested (limit test). No inhibition of growth was observed over an exposure period of 16 h. Hence, the EC10 (16 h) is determined to be > 10,000 mg/L based on the nominal concentration.
