Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Transport and distribution
Koc: The determined Koc value of 417 (log Koc 2.62) (HPLC, OECD TG 121) indicates that the substance will have a low potential to adsorb to sediment/soil (< 500).
Henry's law constant: To assess the volatilisation potential of the substance a Henry's law constant was calculated which showed a value of 2.44 Pa.m3/mol at 25°C. This value is used in distribution modelling and shows that volatilisation only plays a minor role in the environmental behaviour of Cyclacet.
Based on Level III distribution modelling using EPISUITE(assuming equal and continuous releases to air, water and soil) using the CAS number 54830-99-8 and the measured physico-chemical parameters as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (75%) and water (24%) with small amounts to sediment and air (both <1%).
The SimpleTreat model, which is incorporated in EUSES, simulates the distribution of the substance in a Sewage Treatment Plant based on vapour pressure, water solubility, log Kow and (non) ready biodegradability. The model predicts that 93% of the substance will partition to water, 5% to sewage sludge and 2% to air at 12°C.
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.
