Description of key information

No toxic effects to fish up to the limit of water solubility.

Key value for chemical safety assessment

Additional information

One experimental study investigating the short-term toxicity of ethylene distearate (CAS 627-83-8) to freshwater fish is available (Wetton, 1996). As it can be seen in the data matrix of the category justification in section 13 and the overall summary, all reliable data in the category support the hazard assessment of each category member by showing a consistent pattern of results.

The limit test was performed according to the OECD Guideline 203 under GLP conditions with the rainbow trout (Oncorhynchus mykiss). A semi-static test design was chosen. No effects were observed after 96 h resulting in a LC50 of > 0.3 mg/L (nominal). 0.3 mg/L was the highest concentration which was soluble in the solubiliser tetrahydrofuran without precipitation. No mortality was observed in the control and solvent control.
