- Conclusions:
- No freezing point or range could be detected.
The freezing point of nerol was stated as < - 20°C. - Executive summary:
The determination of the melting point was performed in accordance with Regulation (EC) No 440/2008, method A.1 “Melting/Freezing Temperature” (May 2008) and OECD Guideline No 102 “Melting Point/Melting Range” (July 1995).
In a preliminary study, the test item was still not frozen after twelve hours of storage in a freezer at - 20°C; according to Annex VII of REACH, no main study was performed. The freezing point or range of nerol was stated as < - 20°C.
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
After twelve hours of storage in a freezer at - 20°C the test item was still liquid.
According to Annex VII of REACH, the study does not need to be conducted below a lower limit of - 20°C. Therefore no main study was performed and the determination was terminated.
Description of key information
In a preliminary study, the test item was still not frozen after twelve hours of storage in a freezer at - 20°C.
Therefore, according to Annex VII of REACH,
no main study was performed.
The freezing point or range of nerol is < - 20°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -20 °C
Additional information
Key study conducted according to OECD 102 and EU A.1 guidelines. The result is scientifically acceptable but not obtained under GLP.
Therefore a reliability of 2 (reliable with restrictions) was assigned.
