Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Partitioning of substances into the different environmental compartments depends mainly on their physico-chemical properties. Since the water solubility of the main constituents of Reaction mass of bis(2-propylheptyl) hexanedioate and O6-[2,2-bis[[6-oxo-6-(2-propylheptoxy)hexanoyl]oxymethyl]butyl] O1-(2-propylheptyl) hexanedioate are very low and the log Pow values high, the constituents are expected to mainly distribute to sediment and soil. However, as the multiconstituent substance is readily biodegradable according to the OECD criteria, the substance will not be persistent in the environment. The constituents are not expected to evaporate into the atmosphere due to the low vapor pressure. Abiotic hydrolysis is not relevant, since the substance is readily biodegradable and thus expected to be eliminated through biodegradation in natural waters. Based on the rapid environmental biodegradation and metabolism via enzymatic hydrolysis, relevant uptake and bioaccumulation in aquatic organisms is not expected. Enzymatic breakdown will initially lead to the free dicarboxylic acid and the free alcohol. From literature it is well known, that these hydrolysis products will be metabolised and excreted in fish effectively (for detailed information please see chapter 5.3 of technical dossiers). This is supported by low calculated BCF values calculated for the constituents and its transient metabolites (BCF << 2000 L/kg ww; BCFBAF v3.01; Arnot-Gobas, including biotransformation, upper trophic).
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.
