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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 283-291-9 | CAS number: 84604-14-8 Extractives and their physically modified derivatives such as tinctures, concretes, absolutes, essential oils, oleoresins, terpenes, terpene-free fractions, distillates, residues, etc., obtained from Rosmarinus officinalis, Labiatae.

Description of key information
Based on the prediction using AOPWIN v1.93 (EpiSuite 4.11), the OH radicals photodegradation rate of the substance is 1.458584E-10 cm³ molecule-1 s-1, and the related DT50 can then be estimated 0.88 hours (AOPWIN v1.93), or 2.64 hours (EUSES v2.1.2). All in being outside the EUSES boundaries (0.99-1.0E+40 d), this DT50 is a more realistic fate of fragrance substance in air, and thus will be used for the environmental CSA.
Key value for chemical safety assessment
- Half-life in air:
- 2.64 h
- Degradation rate constant with OH radicals:
- 0 cm³ molecule-1 s-1
Additional information
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.
