Description of key information

No effects up to the limit of water solubility (< 0.05 mg/L, OECD 211).

Key value for chemical safety assessment

Additional information

One study is available investigating the chronic toxicity of dodecyl oleate (CAS 36078-10-1) to aquatic invertebrates (Brunswik-Titze, 2013). The study was performed according to OECD 211 under GLP conditions with the water flea Daphnia magna. Five nominal concentrations up to 100 mg/L were tested in a semi-static exposure system as Water Accommodated Fractions (WAF). No effects on the reproduction of D. magna were observed after 21 d. One dead animal was recorded at 50 mg/L but it was reported that it was no substance specific effect (accident during medium change). Therefore, a NOELR (21 d) of ≥ 100 mg/L (nominal) was derived. The chemical analysis resulted in concentrations below the analytical detection limit of 0.005 mg/L reflecting the very low water solubility of the test item. Based on the result it can be concluded that dodecyl oleate will not exhibit chronic effects on aquatic invertebrates up to the limit of water solubility.
