Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
14 August 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Qualifier:
no guideline followed
Principles of method if other than guideline:
100g of Chamomile oil was slowly cooled in a 250 ml round bottomed flask using a cardice jacket in a vacuum flask within a fume cupboard. Cardice is solid Carbon dioxide at a temperature of minus 78 deg C. The liquid in the flask had a temperature probe capable of recording temperatures down to minus 40 deg C.
GLP compliance:
no
Type of method:
method to determine freezing temperature
Key result
Melting / freezing pt.:
< -35 °C
Atm. press.:
1 atm
Conclusions:
Anthemis nobilis, ext., (Chamomile oil) did not freeze when cooled to -35 deg C
Executive summary:

The melting/freezing point of Anthemis nobilis, ext., (Chamomile oil) was determined to be below -35 deg C.

Description of key information

The melting/freezing point of Anthemis nobilis, ext., (Chamomile oil) was determined to be below -35 deg C (Pitman, 2018a).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-35 °C
