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 invertebrates up to the limit of water solubility (< 0.05 mg/L).
Key value for chemical safety assessment
Additional information
Two studies investigating the short-term toxicity to aquatic invertebratesfatty acids, C16-18 and C18-unsatd., tetraesters with pentaerythritol (CAS 68604-44-4)are available (Wierich, 1998; Junghans, 2010).
Short term toxicity to aquatic invertebrated was investigated a the key study performed under static conditions and GLP according to EU Method C.2 usingDaphnia magnaas test organism (Wierich, 1998). The WAF was prepared by adding the appropriate amount of test substance with subsequent stirring and filtering. A nominal test concentration of 100 mg/L was tested, corresponding to < 10 mg/L (detection limit). No immobilization was observed in the treatment and the control throughout the test period of 48 h. Hence, the 48 h-EL50 is determined to be > 100 mg/L based on the nominal test concentration. This result is confirmed by a supporting study, conducted according to OECD 202 (Junghans, 2010). Also in this limit test an EL50 > 100 mg/L based on nominal values could be determined.
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 short-term effects to aquatic invertebrates 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 summary, all reliable data in the category support the hazard assessment of each category member by showing a consistent pattern of results, i.e.no toxic effects to aquatic invertebrates or other aquatic organisms were observed up to the limit of water solubility.
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).
