Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 of the substance were determined from experimental testing, except Partition Coefficient that was derived from an analogue substance. Some endpoints were waived, based on the chemical structure of constituents.

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

In water, it is slightly soluble, and no surface-active properties are anticipated.

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

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