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 aquatic algae up to the limit of water solubility (< 0.05 mg/L).

Key value for chemical safety assessment

Additional information

One study investigating the toxicity to aquatic algae and cyanobacteria offatty acids, C16-18 and C18-unsatd., tetraesters with pentaerythritol (CAS 68604-44-4) isavailable (Junghans, 2010). The limit study was performed according to OECD 201. The green algae Desmodesmus subspicatus was exposed to a nominal concentration of 100 mg/L. The test solution was prepared by adding the appropriate amount of test substance with subsequent stirring followed by filtration. No effect on growth rate and biomass of Desmodesmus subspicatus up to the limit of water solubility was observed resulting in an EL50 > 100 mg/L (nominal) and a NOELR of ≥ 1000 mg/L (nominal). Based on these results, it can be concluded thatfatty acids, C16-18 and C18-unsatd., tetraesters with pentaerythritol (CAS 68604-44-4)will not exhibit effects to aquatic algae 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 results, no toxic effects were observed to aquatic algae or other aquatic organisms up to the limit of water solubility.
