Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Vapour Pressure, Water Solubility and Auto-Ignition Temperature that were derived from an analogue substance. Some endpoints were waived, based on chemical structure.

The substance is a fluid liquid at ambient temperature, less dense than water and with low volatility.

It is slightly soluble in water, with no surface-active properties, and no dissociation anticipated.

It has potential for bioaccumulation and aquatic chronic toxicity, based on CLP criteria.

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