Description of key information
The substance was in the range of water solubility not toxic under test conditions. The EC50 of 1,2-Benzenedicarboxylic acid, di-C6-10-alkyl esters was in excess of 2.8 mg/L.
Key value for chemical safety assessment
Additional information
The substance was in the range of water solubility not toxic under test conditions.The EC50 of 1,2-Benzenedicarboxylic acid, di-C6-10-alkyl esters was in excess of 2.8 mg/L. Additional information from a publication (Adams et al., 1995) support these findings. Also the toxicity of structurally related phthalates has been evaluated in several algae tests according to accepted guidelines.
The EC50, based on cell numbers, after 72 hours and 8 days was not affected in the range of the water solubility, the highest concentration tested being 3.3 mg/L.
The results are supported by results summarized in review articles for phthalates with alkyl chain length of C6 and above.
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.
