Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 solubility of the butylene oligomers  is estimated to range from 0.135 - 9.2 mg/l

Key value for chemical safety assessment

Additional information

In the absence of measured data for the solubility of the butylene oligomers, solubility was estimated using WSKOWWIN in EPISuite 4 (2009) which estimates the water solubility (WSol) of an organic compound using the compounds log octanol-water partition coefficient (Kow).  WSKOWWIN requires only a chemical structure to estimate Wsol. The calculated water solubility of the members of the category ranged from 10.135 to 9.2 mg/l

An additional study for the solubility of 97280 -83 -6 was available but the exact solubility of 97280 -83 -6, was not determined due to the limit of detection of the analytical method. However the upper limit of solubility was measured in a guideline proprietary study (Evonik Oxeno 2009) as 2.4 mg/L at 20°C. This solubility supports the estimated solubility of the members of the category.
