Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Endpoint summary
Administrative data
Description of key information
Physico-chemical properties of registered substance were determined from experimental testing,except water solubility, partition coefficient and vapour pressure that were derived from available data on constituents in a constituents approach. Some endpoints were waived, based on chemical structure of constituents or experience in handling and use of the substance.
The substance is a pale yellow to green organic liquid at ambient temperature,with low volatility. In water the constituent with highest solubility has a solubility of 1.11 mg test/L, therefore the test item has a low solubility. The test item is less dense than water, so likely float.
No surface-active properties is anticipated.
It has a log KoW between 4.3 and 6.8.
It is not classified as hazardous with regard to some physical hazards (explosivity, oxidising properties, self-heating, self reactive substance and organic peroxide) and it is classified as a flammable liquid based on Regulation (EC) 1272/2008 (CLP regulation).
