Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The water solubility of Arctical was determined to be < 0.0151mg/L @ 20 ± 0.5 °C using OECD TG 105 using the flask method. For deriving a discrete value a QSAR value is used from WSKOW using log Kow 5.4 and results in 1.3 mg/l.
Key value for chemical safety assessment
- Water solubility:
- 1.3 mg/L
- at the temperature of:
- 20 °C
Additional information
The experimental water solubility has been determined as a < value. Running WSKOW, using log Kow of 5.4 as input, a water solubility of 1.3 mg/l is calculated. The water solubility in the ecotoxicity tests show a maximum of 0.13 mg/l, though the variability was high depending on the stirring time and centrifugation (0.06 -2.5 mg/l). For the risk assessment the value of 1.3 mg/l is used which seems to be fairly indicative of the values found. A good explanation for the variability in the results is not available.
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.
