Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Preliminary solubility estimated based on column elution method < 1 µg/L at pH: 7.0 - 7.1, 20°C. Calculated solubility (software WSKOWIN®, v.1.4) 8.6 x 10E05 mg/L at 25°C. The results are based on the main component (oligomer n=2).
Key value for chemical safety assessment
Additional information
The preliminary experiment on water solubility of Poly-1,4-Diisopropylbenzene was below the detection limit of the column elution method used. Thus, no experimental main test was performed and the water solubility was estimated by a Atom/Fragment Contribution Method using the software WSKOWIN® version v1.4 (Syracuse Research Corporation, New York, USA).
The software WSKOWIN® calculated a water solubility of the main component (dimer) of 8.6 x 10E-05 mg/L at 25°C. This is in good agreement with the preliminary estimate on water solubility of < 1 µg/L based on the column elution method at 20°C, pH 7.1. The test item is considered to be not water soluble.
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.
