Key value for chemical safety assessment
Additional information
In accordance to Regulation (EC) No. 1907/2006 Annex XI, 1.5 a read across to a structurally related substance Fatty acids, C16-18 and C18-unsatd., hexaesters with dipentaerythritol (CAS 68604-38-6) was conducted to fulfill the data requirements according to Annex VII-IX of Fatty acids, tall oil, esters with dipentaerythritol (CAS 70913-98-3) regarding short term toxicity to fish. This read-across is justified in detail within the analogue justification in IUCLID Section 13. The fatty acid chain lengths of C16, C18 and C18 unsatd. of the read-across substance is identical to those of the target substance. In addition, the read-across substance contains the same alcohol component, i.e. dipentaerythritol, and is a hexa-ester.
A GLP study following OECD guideline 203 is available for the read-across substance Fatty acids, C16-18 and C18-unsatd., hexaesters with dipentaerythritol (CAS 68604-38-6) (Caduff, 2013). The test was conducted as a limit test with zebra fish (Danio rerio) as test organism. The study was set up in a static test system. The fish were exposed to the water accommodated fraction (WAF) of the test substance. At test termination after 96 hours a LL50 > 100 mg/L (NOEC ≥ 100 mg/L) based on nominal test substance loading rate was determined.
Based on these results from a structurally related read-across substance (in accordance to Regulation (EC) No 1907/2006 Annex XI, 1.5) which is characterized by a similar ecotoxicological profile, it can be concluded that Fatty acids, tall oil, esters with dipentaerythritol (CAS 70913-98-3) will not exhibit effects to fish 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).
