Description of key information
The test substance 1,2-Benzenedicarboxylic acid, di-C6-10-alkyl esters was not tested. In the range of water solubility the structural related substance 1,2-Benzenedicarboxylic acid, di-C8-10-alkyl esters was not toxic under test conditions.The 96 hour LC50 was in excess of 0.32 mg/L, the highest concentration investigated which was at or in excess of the water solubility of the substance.
Key value for chemical safety assessment
Additional information
The acute toxicity of various phthalate esters was assessed in a number of freshwater species over a 96 hour period. No toxicity was observed up to the highest concentration tested. The 96 hour LC50 of the structural related substance 1,2-Benzenedicarboxylic acid, di-C8-10-alkyl esters was in excess of 0.32 mg/L, the highest concentration investigated which was at or in excess of the water solubility of the substance. For the another structurally related substances the LC50 in rainbow trout was in excess of 1.4 mg/L, in fathead minnow was in excess of 1.3 mg/L and in bluegill was in excess of 0.73 mg/L. These values represent the highest concentrations examined which were at or in excess of the water solubility of the phthalates.
Acute toxicity to a marine species, sheepshead minnow, has also been determined with the structurally related substance Diundecyl phthalate. The 96 hour LC50 was in excess of 0.22 mg/L, the highest concentration investigated which was at or in excess of the water solubility of the substance.
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.
