Description of key information
No effects up to the limit of water solubility (< 0.05 mg/L, OECD 201).
Key value for chemical safety assessment
Additional information
One GLP Guideline study is available investigating the toxicity of 2-octyldodecyl isooctadecanoate (CAS 93803-87-3) to aquatic algae is available (Bogers, 1998). The study was performed according to OECD 201 with the freshwater algae Selenastrum capricornutum. Water Accommodated Fractions (WAF) of nominal 10 and 100 mg/L were prepared and tested under static conditions. A chemical analysis of the test substance concentrations in the test vessels was not possible since no applicable method could be established due to the very low water solubility to detect test concentrations. An inhibition of cell growth (31.2%) was observed after 72 h in the WAF test solution of 100 mg/L, whereas no inhibition was observed in the WAF test solution of 10 mg/L. It was reported that this effect is probably related to insoluble particles which might have adsorbed fractions of light needed for algal cell growth. However, the growth rate was not inhibited resulting in an EL50 (72 h) of > 100 mg/L and a NOELR (72 h) of ≥ 100 mg/L. Based on this result it can be concluded that no toxicological effects on aquatic algae are expected up to the limit of water solubility for 2-octyldodecyl isooctadecanoate.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
