Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Justification for read-across:
The High Molecular Weight Phthalate Ester (HMWPE) Category consists of phthalate esters with an alkyl carbon backbone with 7 carbon (C7) atoms or greater. The category is formed on the principle that substances of similar structure have similar toxicological properties. The data available on high molecular weight phthalates demonstrate that members of this category have similar biological activities and toxicological properties; verifying the use of read-across data as an appropriate approach to characterize endpoints. Both substances named DTDP are high molecular weight phthalate esters (C13), diisotridecyl phthalate (CAS number 27253-26-5, EC number 248-368-3) and 1,2-Benzenedicarboxylic acid, di-C11-14-branched alkyl esters, C13-rich (CAS number 68515-47-9, EC number 271-089-3). Both are isomeric mixtures of C13 branched alkyl esters, the starting material being different but both starting materials consisting of various isomers of multibranched C13 alcohols. Where data maybe lacking for DTDP, DINP (C9) and DIDP (C10), which are also high molecular weight phthalate esters, are used as read-across substances to provide toxicological information.
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.
