Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information
Adsorption/Desorption
Based on a calculated log Koc of 7.08 (MCI method) or 8.00 (log Kow method) for the component diisotridecyl adipate is expected to have a high potential for accumulation in soil and sediment (MWC, 2010). Log Koc of the component diisotridecyl sebacate was calculated to 8.055 (MCI method). Optionally, log Koc was estimated to 9.002 using log Kow. Therefore also for this component is a high potential for accumulation in soil and sediment. The McCall classification scheme classifies the substances as immobile in soil (Koc>5000).
Henry's Law constant
The Henry's law constant (HLC) of the component diisotridecyl adipate at 25°C was estimated by calculation methods (program US EPA EPI Suite v4.00) (MWC 2010).
Bond contribution method: HLC (25°C) = 8.89 Pa*m3/mol
Group contribution method: HLC (25°C) = 6.83 Pa*m3/mol
Diisotridecyl adipate will volatilize from water.
Distribution modelling
Estimates obtained from Level III fugacity distribution modelling using US EPA EPI Suite v4.00, indicate that emissions of the component diisotridecyl adipate will distribute mostly in soil (84.9%) and to a lesser extend in water (14.8%). The fractions in air (0.28%) and in sediment (0.02%) are minimal. The estimated persistence time is 1310 hr (ca. 55 days) (MWC 2010).
Other distribution data
Volatilization from Water
Using the calculated Henry's Law Constant (HLC) of 8.89 Pa*m³/mol at 25 °C, the component diisotridecyl adipate volatilization half-lifes from a model river and a model lake were estimated to 4.3 and 236 hours (ca. 0.2 and 10 days), respectively (MWC 2010).
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).
