- Short-term EC50 or LC50 for soil macroorganisms:
- 47.4 mg/kg soil dw
Additional information
No experimental data are available for the target substance MDEA-Esterquat C18 satd. However, an acute toxicity study to earthworms is available for the closely related source substance MDEA-Esterquat C16 -18 and C18 unsatd..
In a 14-day acute toxicity study, earthworms (Eisenia fetida) were exposed to MDEA-Esterquat C16-18 and C18 unsatd. at 0, 2.20, 4.74, 10.2, 22.0, 47.4 mg a.i./kg dry soil (artifical soil). The experiment was carried out according to OECD TG 207. The 14 day LC50 value was determined to be >47.4 mg a.i./kg soil dry weight (nominal). The 14 d EC50 was >47.4 mg a.i./kg dry soil. The 14 d NOEC and LOEC, based on appearance and behaviour was >47.4 mg a.i./kg dry soil. No compound related toxicity effects were noted.
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).
