Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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, or calculated from QSAR. Some endpoints were waived, based on the chemical structure of the two major constituents or experience.

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

In water, the major of the two constituents is 40-50x more soluble than the second one; no surface-active properties are anticipated.

It has low potential for bioaccumulation.

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