Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The substance belongs to a group of Natural Complex Substances (NCS) : UVCB sub-type 3, where the source is biological and the process is refinement (See ECHA Guidance on Identification and naming of substances under REACH); such as: exudates, resinoids and concretes that are well-known to be very difficult to analytically assess. These complex UVCB substances contain a large number of constituents with different volatility and solubility (mostly low solubility); the composition can be widely unknown and their physical state ((mostly) solid(ish) and/or extremely viscous resins) leads to further difficulties for testing.


Considering the very complex nature of the test item (UVCB, viscous liquid, mainly composed of unknown constituents), physico-chemical properties of the registered substance were determined from experimental testing when possible. Some endpoints were waived, based on the experience in handling and use of the substance and on the chemical structure of the known constituents. We also considered waiving based on the technical issues due to the complex nature of such UVCB substance especially when the information obtained from testing was not relevant or of practical use and irrelevant for subsequent assessments.

The substance is brownish viscous liquid at ambient temperature. Melting point, boiling point, density, flash point, explosive properties, auto-ignition temperature and oxidasing properties studies are on going (deadline planned by the laboratory: May 2018).
