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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 282-029-0 | CAS number: 84082-82-6 Extractives and their physically modified derivatives such as tinctures, concretes, absolutes, essential oils, oleoresins, terpenes, terpene-free fractions, distillates, residues, etc., obtained from Salix alba, Salicaceae.
Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is a solid which decomposes before boiling

Description of key information
Decomposition before melting
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 160 °C
Additional information
To determine the melting and boiling point of the submission substance, differential scanning calorimetry in open crucibles was applied (aluminium with a hole; open glass crucible). At finalisation, both measurements showed an expanded foamy mass.
Results / conclusions
Under consideration of the results from the thermal stability (see report PS20180395-10; DSC in closed crucibles), the DSC measurements and the capillary method, it is concluded that the test item decomposed before melting or boiling could occur. Therefore, it was concluded that the test item had no melting point and no boiling point at atmospheric conditions.
From experiments with open crucibles, the onset temperature of decomposition is difficult to estimate due to the unusual peak shape but is around 160 °C. Accordingly, the theoretical boiling boint is above 160 °C, and 160°C is given as the key value for chemical safety assessment.
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.
