Description of key information
Additional information
No data on toxicity to terrestrial organisms are available except a phytotoxicity study according to OECD 208 [Ciba-Geigy 1991] determining effects on emergence and growth. Effects (dried leaves) were observed at 100mg/kg on turnip (Brassicaceae). However, some experimental details are missing in the report (e.g. number of seeds per pot is not mentioned, number of replicates etc). The particles < 20 μm were not determined and the soil was not sieved. Furthermore, the calculations of EC50 concentrations is not assignable for the reviewer. Therefore, the study was disregarded.
No further studies on toxicity to terrestrial organisms are proposed as the soil compartment is not regarded as relevant compartment for Octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate.
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.
