Additional information
Conclusion on classification
4,4’-(1-phenylethane-1,1-diyl)bis(heptyloxybenzene) is not classified as a toxic substance (T) based on available reliable data for toxicity of4,4’-(1-phenylethane-1,1-diyl)bis(heptyloxybenzene) to fish, invertebrates and algae. The water solubility of 4,4’-(1-phenylethane-1,1-diyl)bis(heptyloxybenzene) was experimentally determined to be ≤ 4.4 x 10-7g/L and it was not possible to reach concentration levels in the available fish, invertebrate and algae studies that might be toxic to aquatic organisms. Consequently, and the L(E)C50 values for the available fish, invertebrate and algae studies were all greater than the limit of solubility in the test media. Therefore, 4,4’-(1-phenylethane-1,1-diyl)bis(heptyloxybenzene) is classified as Potentially T as laid down in Annex XIII of Regulation (EC) No. 1907/2006 since toxicity cannot be ruled out based on acute data only, but realistically the substance should be considered non-toxic to aquatic organisms.
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.
