Reference
Endpoint:
boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
07 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 heated in a 250 ml round bottomed flask using an electric heating mantle in a fume cupboard at atmospheric pressure. The temperature at which boiling commenced was measured with a thermometer calibrated in degrees centigrade.
GLP compliance:
no
Type of method:
other: Observation of commencement of boiling.
Key result
Boiling pt.:
178 °C
Atm. press.:
1 atm
Remarks on result:
other: Initial boiling temperature of UVCB
Conclusions:
Anthemis nobilis, ext., (Chamomile oil) a complex UVCB, had an initial boiling point of 178 deg C
Executive summary:

The initial boiling point of Anthemis nobilis, ext., (Chamomile oil) was determined to be 178 deg C. As Chamomile oil is a complex mixture, the boiling point will increase as more oil is boiled off.

Description of key information

Anthemis nobilis, ext., (Chamomile oil) a complex UVCB, had an initial boiling point of 178 deg C (Pitman, 2018b).

Key value for chemical safety assessment
