Description of key information

Additional information

Three experimental OECD guideline studies (GLP) are available, which assessed the aquatic toxicity of the substance on two different trophic levels with Diisodecyl azelate (CAS 28472-97-1). One acute study was available with fish (Institut für gewerbliche Wasserwirtschaft und Luftreinhaltung e.V., 1993; Leuciscus idus; LC50 (96 h) >10000 mg/L) and one chronic study with Daphnia magna (Charles River, 2016; NOELR (21 d) 4.0 mg/L) and one study testing the toxicity to microorganisms (Institut für gewerbliche Wasserwirtschaft und Luftreinhaltung e.V.; EC10 (16 h) > 10000 mg/L). In order to fulfill the standard information requirements set out in Annex VII - X, in accordance with Annex XI, 1.5, of Regulation (EC) No 1907/2006, read-across from structurally related substances was conducted for the missing endpoint of acute toxicity to algae (Pseudokirchneriella subcapitata; EC50 (72 h) >0.0845 mg/L; NOEC (72 h) ≥ 0.0845 mg/L).
