Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
With high probability acute not harmful to fish, no toxic effects occur at the range of solubility.
Key value for chemical safety assessment
Additional information
For octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate two static studies in fish (bluegill and rainbow trout) are available. Both were performed according to the OECD guideline, except that the exposure solutions were prepared using a dispersant (>100 mg/l). Test concentrations were 0, 10, 18, 32, 58 and 100 mg/L. Measured concentrations were greatly in excess of the water solubility of octadecyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate. No treatment related mortality was observed. The 96-h LC50 for both species was >100 mg/L and thus above the water solubility (Ciba-Geigy, 1984 a and b).
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.
