Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Long-term toxicity to aquatic algae: No effects at saturation based on experimental data and supported by QSAR estimates.
Key value for chemical safety assessment
Additional information
The data used to characaterize the algal toxicity of di-isodecyl phthalate ester (DIDP; CAS #68515-49-1) ester are consistent with the data for several high molecular weight phthalate diesters summarized by Staples et al. (1997). These data show that high molecular weight phthalate diesters do not produce toxicity to algae at or below their maximum attainable water solubliity. The algal dataset includes results for one species, Selenastrum capricornutum (new name: Pseudokirchnerella subcapitata). This is further supported by QSAR estimations for esters, where due to the hydrophobicity of the molecules leads to no effects at saturation.
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.
