Description of key information
No studies with relevance to the terrestrial compartment are available for Fatty acid C18- unsat, dimer compd. with coco alkylamine. However, as concluded in chapter “aquatic toxicity” the intrinsic toxic properties of Fatty acids C18- unsat, dimers compd. with coco alkylamine are driven by the component coco alkylamine,it is expected that effects in the terrestrial compartment will also be driven by the toxic properties of coco alkylamine. Therefore, the evaluation of effects in the terrestrial compartment will be related to coco alkylamine.
Coco alkylamine:
In a valid chronic earthworm study a NOEC of 200 mg/kg soil was deviated.
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for soil macroorganisms:
- 200 mg/kg soil dw
Additional information
No studies with relevance to the terrestrial compartment are available for Fatty acid C18- unsat, dimer compd. with coco alkylamine. However, data are available for the two main components. Furthermore, as concluded in chapter “aquatic toxicity” the intrinsic toxic properties of Fatty acids C18- unsat, dimers compd. with coco alkylamineare driven by the component coco alkylamine,it is expected that effects in the terrestrial compartment will also be driven by the toxic properties of coco alkylamine. Therefore, the evaluation of effects in the terrestrial compartment will be related to coco alkylamine.
Fatty acids C18-unsat., dimers (C36)
Although Fatty acids C18-unsat., dimers (C36) have a high KOC and are not readily biodegradeable, they display no toxic properties as shown in acute toxicity test with fish, daphnia and algae with L(E)C50 values of > 1000 mg/l. The risk assessment based on the EPM method revealed for this component no indication for further testing.
This assumption is confirmed by a newly available chronic earthworm test according to OECD 222. After 56 d exposure the NOEC with regard to reproduction was >= 1000 mg/kg soil dw.
Coco alkylamine:
Although, coco alkylamine is the driving force with regard to ecotoxic properties, the substance is readily biodegradable. In accordance with Guidance on information and chemical safety assessment Chap. R.7c -Endpoint specific guidance, there is no need to perform further testing on terrestrial organisms if the substance is readily biodegradable and not directly applied to soil. Based on the uses of Fatty acid C18- unsat, dimer compd. with coco alkylamine there is no direct or indirect exposure of the terrestrial compartment for the component coco alkylamine.
However, in the EU risk assessment for primary alkylamine also for the terrestrial compartment a PNEC soil was deviated based on available information for the alkylamines. The EU risk assessments refers to a valid chronic earthworm study in which a NOEC of 200 mg/kg was derived. The PNEC is indicated to be 2 mg/kg d.w. based on an AF of 100.
