Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

not specified
Qualifier:
according to guideline
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
not specified
GLP compliance:
no
Type of method:
method to determine freezing temperature
Melting / freezing pt.:
< -20 °C

The test item was still not frozen after twelve hours of storage in a freezer at - 20°C.


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.

Conclusions:
According to guideline OECD 102 and method EU A.1, no melting point of substance (+)-CAMPHOLENIC ALDEHYDE was observed from - 20°C.
Executive summary:

The purpose of the study was to determine the Melting/Freezing point of substance (+)-CAMPHOLENIC ALDEHYDE.


The determination of the melting point was performed in accordance with Regulation (EC) No 440/2008, method A.1 ''Melting/Freezing Temperature'' and OECD Guideline No 102 ''Melting Point/Melting Range''.


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, the study does not need to be conducted below a lower limit of -20°C. Therefore the determination was terminated.


The Melting/Freezing point of substance (+)-CAMPHOLENIC ALDEHYDE should be stated as < - 20°C.

Description of key information

Melting point of substance (+)-CAMPHOLENIC ALDEHYDE 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 the OECD 102 Guideline and the EU A.1 method, not under GLP, with some lack of details but with certificate of analysis included. Therefore, a reliability of 2 is assigned and the result of this key study is proposed as the end point value.
