- < -80 °C
- Atm. press.:
- 1 atm
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- No melting point or range could be detected.
The melting point or range of the test item MYRCENE is < -80 °C (193.15 K). - Executive summary:
As test item MYRCENE was still not frozen after six days of storage in a deep freezer at -80°C, no melting point or range could be detected.
Therefore the melting point or range of test item MYRCENE (123-35-3) should be stated as < -80°C (193.15 K).
No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid.
Reference
The test item was filled into glass vessels and stored at –80 and –20°C.

After six days of storage in the deep freezer, the test item was still liquid. Therefore no main study was performed and the detremination was finished.
Description of key information
As the test item was still not frozen after six days of storage in a deep freezer at -80°C, no melting point or range could be detected.
Therefore the melting point or range of test item MYRCENE (123-35-3) should be stated as < -80°C (193.15 K).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -80 °C
Additional information
Key study conducted according to the OECD 102 and EU A.1 guidelines, under GLP without deviation and with certificate of analysis included. Therefore the result of the key study is proposed as end point value. It is confirmed by an available Handbook data.
