Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

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

NOEC (56d) >= 1000 mg/kg dw (Eisenia fetida, OECD 222); read-across

Key value for chemical safety assessment

Additional information

Since no studies investigating the toxicity to soil macroorganisms of Fatty acids, C6-18, 2,2-dimethyl-1,3-propanediyl esters (CAS No. 91031-27-5) are available, in accordance to Regulation (EC) No. 1907/2006 Annex XI, 1.5 a read across to the structurally similar category member 2,2-dimethyl-1,3-propanediyl dioleate (CAS No. 42222-50-4) is conducted. Further justification is given within the endpoint summary in IUCLID chapter 6.3 and within the category justification in IUCLID section 13.

The key study conducted with 2,2-dimethyl-1,3-propanediyl dioleate (CAS No. 42222-50-4) was performed according to OECD Guideline 222 and GLP (Amsel, 2013). The test organism Eisenia fetida was exposed to the nominal test concentrations of 62.5, 125, 250, 500 and 1000 mg/kg soil dw for 56 days. No significant effects on reproduction were observed, and the NOEC was reported to be ≥ 1000 mg/kg dw.
