Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Some physico-chemical properties were available from experimental testing, or estimated by QSAR.

The substance is liquid at ambient temperature, with low volatility and low water solubility.

Based on CLP and GHS criteria:

- it has potential for bioaccumulation and aquatic chronic toxicity,

- it is NOT classified as a flammable liquid or an explosive,

- it has potential for Aspiration Hazard.
