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


Based on a calculated log Koc of 7.08 (MCI method) or 8.00 (log Kow method) diisotridecyl adipate is expected to have a high potential for accumulation in soil and sediment (MWC, 2010).The McCall classification scheme classifies the substances as immobile in soil (Koc>5000).

Henrys Law constant

The Henry's law constant (HLC) of 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) = 88.9 Pa*m3/mol

Group contribution method: HLC (25°C) = 68.3 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 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 88.9 Pa*m³/mol at 25 °C, 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).
