Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Adsorption / desorption
The log of the adsorption coefficient (KOC) of Stoddard solvent was estimated to be log KOC = 3.1616 which is equal to a KOC value of 1451 using the KOCWIN v2.00 QSAR method. Estimate from MCI.

Henry's Law constant
The estimated Henrys Law Constant (25 deg C) measured by calculation from EPI SuiteTM v4.1, HENRYWIN v3.20 Program was 6.74E+000 atm-m3/mole (6.83E+005 Pa-m3/mole). This is Exposure Assessment Tools and Models made from EPA (Environmental Protection Agency).
Distribution modelling.
Stoddard solvent has no affinity to be in soil and sediment. The direct emissions to air and surface water are significant, therefore Stoddard solvent will be almost exclusively be found in air and surface water.
Mackay fugacity modelling (level 3) indicates that, taking into account degradation and using inflow parameters which are consistent with the known production tonnage of this substance in, fugacity coefficient indicates that environmental concentrations in water are predicted to be 2.63e-005(atm), in air (atm) 9.8e-011and soil 9.53e-008 (atm) and sediment to be 1.22e-005 (atm).
These are negligible low levels. This can be considered a worse case prediction as it assumes all product is emitted with no emission control systems used
Additional 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.
