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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 282-012-8 | CAS number: 84082-67-7 Extractives and their physically modified derivatives such as tinctures, concretes, absolutes, essential oils, oleoresins, terpenes, terpene-free fractions, distillates, residues, etc., obtained from Myrtus communis, Myrtaceae.

Description of key information
Major components ranging between 2.74 and 4.83 (literature and QSAR).
Potential concern for classification in aquatic chronic toxicity hazard class (log Kow > 4).
Key value for chemical safety assessment
Additional information
No study was conducted on the oil itself.
In a Weight of Evidence approach, literature provided data for three of the four major components:
- cineole log Kow ca 2.74,
- alpha-pinene log Kow ca 4.83,
- limonene log Kow ca 4.57.
For myrtenyl acetate, no literature data was available, so the dataset was completed with a valid QSAR estimation: log Kow ca 3.75.
As no CSA is required for the tonnage band of concern, no key value was retained (nor calculated weighted value nor worst-case). However, for Classification purpose, the worst case is considered (log Kow > 4).
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.
