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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 287-316-4 | CAS number: 85480-37-1 Extractives and their physically modified derivatives such as tinctures, concretes, absolutes, essential oils, oleoresins, terpenes, terpene-free fractions, distillates, residues, etc., obtained from Melaleuca leucadendron, Myrtaceae.

Description of key information
Estimated global solubility of ca 672 mg oil/L (1 g/L loading rate)
Major components ranging between 710 and 3500 mg/L at ambient temperature (literature).
Key value for chemical safety assessment
Additional information
No study was conducted on the oil itself, but measurement performed on a 90% saturated solution provides an estimated global solubility, based on DOC, of ca 672 mg/L for a 1 g/L loading rate.
In a Weight of Evidence approach, literature provided data also for the two major components:
- cineole WS ca 3500 mg/L,
- alpha-terpineol WS ca 710 mg/L (at temperatures between 21 and 25°C).
As no CSA is required for the tonnage band of concern, no key value was retained (nor calculated weighted WS nor worst-case).
Moreover, as a UVCB with constituents of different solubility, the global solubility of the oil will depend on the loading rate (with varying ratio of constituents in the dissolved phase).
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.
