Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The chronic toxicity of the substance to terrestrial plants was tested according to OECD Guideline 208 (Terrestrial Plants Test: Seedling Emergence and Seedling Growth Test). Five to seven different test item concentrations per species were tested against a solvent control (acetone) with each of the six plant species. No significant effect on seedling emergence or mortality was observed for any of the six test species. Effects were observed for shoot length and fresh weight. Shoot length and shoot fresh weight of B. napus seedlings was significantly reduced at concentrations of 15.6 and 62.5 mg/kg soil dw, respectively. Hence, B. napus was the most sensitive species with regard to shoot length and weight.
Key value for chemical safety assessment
- Long-term EC10, LC10 or NOEC for terrestrial plants:
- 7.8 mg/kg soil dw
Additional information
No toxicity to terrestrial plants for 6PPD is available. 7PPD is an analogue substance. Due to the analogous structure of 7PPD, this study is used in a read-across approach for 6PPD. A detailed justification for the read-across is given in a separate document attached to IUCLID chapter 13.
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.
