Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Physical & Chemical properties

Endpoint summary

Administrative data

Description of key information

Physico-chemical properties were determined from experimental testing, except Auto-Ignition Temperature that was derived from a structural analogue. Some endpoints were waived, based on chemical structure.

The substance is a liquid at ambient temperature, with low volatility.

In water, it is slightly soluble, less dense, with no surface-active properties anticipated (i.e. excess will floate).

It has potential for bioaccumulation.

It is NOT classified as dangerous with regard to physical hazards, based on CLP criteria.
