Description of key information
The LC50 (96 h) of FAT 41030/A was determined to be greater than 100 mg/L based on the nominal concentrations. The same is concluded for its structural analogue FAT 41045.
Key value for chemical safety assessment

Additional information
The acute toxicity of FAT 41030/A, a structural analogue of FAT 41045, to zebrafish was determined according to OECD test guideline No. 203 in compliance with GLP in a 96 hour semi-static test. Both substances are very similar in their chemical structure and, as demonstrated, in a number of physicochemical properties. Therefore, the use of this study for read-across is considered to be appropriate.
No mortality of fish was recorded in the control and the nominal test concentration of 100 mg/L FAT 41030/A during the 96 hour exposure period. No sublethal effects such as changes in swimming behaviour, respiratory function, pigmentation or loss of equilibrium were observed in the control or the treatment concentration of 100 mg/L during the 96 hour test period. Thus, the LC50 (96 h) of FAT 41030/A was determined to be greater than 100 mg/L based on the nominal concentrations.
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.
