Description of key information
The 56d-NOEC (reproduction, mortality and body weight) is ≥ 993.2 mg/kg dry weight in a OECD guideline 222 test with Eisenia fetida under GLP (reliability 1) in a read-across study from N-[(9Z)-octadec-9-en-1-yl]propane-1,3-diaminium di[(9Z)-octadec-9-enoate] (CAS no. 34140-91-5).
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for soil macroorganisms:
- 993.2 mg/kg soil dw
Additional information
The terrestrial toxicity is read across from a study with N-[(9Z)-octadec-9-en-1-yl]propane-1,3-diaminium di[(9Z)-octadec-9-enoate] (CAS no. 34140-91-5). Effects of N-[(9Z)-octadec-9-en-1-yl]propane-1,3-diaminium di[(9Z)-octadec-9-enoate] on mortality, biomass and the reproductive potential of the earthworm species Eisenia fetida (Savigny) were determined according to the Guidelines DIN ISO 11268-2 (1998), OECD 222 (2004) and BBA (1994). The study was conducted under static conditions over 8 weeks with five different application rates of 62.5 – 125 - 250 - 500 - 1000 mg test item/kg soil dry weight, which were mixed into natural soil. Overall, the NOEC ofN-[(9Z)-octadec-9-en-1-yl]propane-1,3-diaminium di[(9Z)-octadec-9-enoate] concerning mortality, biomass and reproduction of earthworms was determined to be ≥ 993.2 mg/kg soil dry weight (based on active ingredient).
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
