Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Adsorption: An experimentally determined Koc value of 1300 L/kg indicates that the substance has moderate potential to adsorb to sediment/soil.
Henry constant: To assess the volatilisation potential of the substance a Henry's law constant was calculated which showed a value of 103 Pa. m3/mol (at 12 °C). Based on this value Verdox will partition from water to air.
Based on Level III distribution modellingusing EPISUITE (assuming equal and continuous releases to air, water and soil) using the CAS number 88-41-5 and the measured physico-chemical parameters, water solubility and log Kow as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (82%) and water (16%) with small amounts to sediment (0.4%) and air (2.1%).
The SimpleTreat model, which is incorporated in EUSES, simulates the distribution of substances in a Sewage Treatment Plant. The results of this model for Verdox show that the substance will not be degraded and that 56.9% of the substance will partition to air, 31.6% will partition to water and 11.5% to sewage sludge.
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.
