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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Colourless, low viscous fluid, reported also as paste/waxy, colourless and odourless (organoleptic inspection)
Key value for chemical safety assessment
- Physical state at 20°C and 1013 hPa:
- liquid
Additional information
According to the melting point data, the substance is molten at 18 -19 °C, thus different descriptions can be used for the physical state at 20 °C and normal pressure: either "viscous fluid" or "paste/waxy" without specification of the aggregate state in terms of solid vs liquid. The viscosity measurement resulting in 30.9 mPa s (OECD 114, rotational viscometer) is an argument that the substance behaviour at ambient conditions is characteristic for a liquid.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
