The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

No toxic effects to fish up to the limit of water solubility (< 0.05 mg/L).

Key value for chemical safety assessment

Additional information

Short-term toxicity of fatty acids, C16-18 and C18-unsaturated, esters with pentaerythritol (CAS 85711-45-1)to freshwater fish was investigated according to OECD 203 under static conditions using Danio rerio (Muckle, 2013). Nominal concentration of 100 mg/L was applied. A water accommodated fraction (WAF) was prepared by adding the required amount of test substance to water with subsequent stirring. The lower phase was used as test medium. DOC analysis of the test substance concentrations indicated that the substance is not soluble in the test medium and the evaluation is hence based on nominal concentrations. No mortalities occurred after the test duration of 96 hours resulting in an LL50 of > 100 mg/L (nominal). Therefore it can be concluded thatfatty acids, C16-18 and C18-unsaturated, esters with pentaerythritol (CAS 85711-45-1)will not exhibit short-term effects to fish up to the limit of water solubility. As it can be seen in the data matrix of the category justification in section 13 and the overall endpoint summary, IUCLID 6.1 all reliable data in the category support the hazard assessment of each category member by showing a consistent pattern of resultswithin the polyol esters category, i.e. no toxic effects to aquatic invertebrates were observed up to the limit of water solubility.
