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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Toxicity to terrestrial plants
Administrative data
Link to relevant study record(s)
Description of key information
Data from a study conducted according to OECD Guideline 208 (Terrestrial Plants Test: Seedling Emergence and Seedling Growth Test) are available.
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for terrestrial plants:
- 84.6 mg/kg soil dw
Additional information
Adequate and reliable data on the short-term toxicity to terrestrial plants are available for C8-18 and C18 unsatd. AAPB (Coco AAPB):
Short-term toxicity
In a study (limit test) conducted according to OECD Guideline 208 (Terrestrial Plants Test: Seedling Emergence and Seedling Growth Test),Triticum aestivum,Brassica alba and Lepidium sativum were exposed to a nominal concentration of 100 mg Coco AAPB/kg soil. A 17 d-NOEC ≥100 mg dry residue/kg soil d.w. nominal (= 84.6 mg a.i./kg) was determined for all three plant species in respect to emergence and growth. Analytical monitoring was not performed.
Long-term toxicity
As recommended in R.7.11.3.1, data obtained from the OECD 208 Guideline study have been used as estimates of chronic toxicity as they cover a sensitive stage in the life-cycle of a plant. The determined NOEC of 84.6 mg/kg (a.i. nominal) was used for PNEC derivation. In addition according to REACH Regulation (Annex X, 9.4, column 2), a study on long-term toxicity on terrestrial organisms does not need to be conducted if no direct or indirect exposure of soil is to be expected. Based on the uses of the test substance, soil is not the target compartment and therefore exposure of soil is expected to be low and furthermore the test substance proved to be readily biodegradable. Therefore additional testing is considered not necessary.
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.
