Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Koc: The determined Koc value of 14300 (log Koc 4.16) (OECD TG 121) indicates that the substance will have a high potential to adsorb to sediment/soil.
Henry's law constant: To assess the volatilisation potential of the substance a Henry's law constant was determined which showed a value of 11.4 Pa. m3/mol at 20°C (5.47 m3/mol at 12°C). Distribution modelling showed that volatilisation only plays a minor role in the environmental behaviour of HHCB.
Based on Level III distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 1222-05-5 and the measured Log Kow as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (73%), with smaller amounts to sediment (16.2%) and water (10.8%) and a negligible amount to air (0.15%).
The SimpleTreat model, which is incorporated in EUSES, simulated the distribution of the substance in a Sewage Treatment Plant based on vapour pressure, water solubility, log Kow and biodegradability. The model predicts that 0% of the substance will biodegrade, 36.9% will partition to water, 60.1% to sewage sludge and 2.99% to air.
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.
