- Adequacy of study:
- key study
- Study period:
- 01 September 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- 440/2008 of 30 May 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- 1995
- Deviations:
- no
- GLP compliance:

- Remarks:
- Inspection date : 15-16 November 2017 ; Certificate date : 15 May 2018
- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- >= 218.22 - <= 219.83 °C
- Atm. press.:
- 1 001.4 mBar
- Decomposition:
- no
- Remarks on result:
- other: Initial boiling point
- The test item is a mixture a boiling range can be expected.
- The onset of the boiling peak is stated as the initial boiling point of the test item.
- As the initial boiling points differ by more than 0.5 K below 327 °C, an initial boiling range is stated for the test item Essential oil of Citrus sinensis (Rutaceae) peel, terpene-free.
- Conclusions:
- The initial boiling point of the test item was stated between 218.22°C and 219.83°C (491.37K - 492.98K)
- Executive summary:
The boiling point of test item was determined in a GLP study according to OECD 103 guideline/ EU. method A2 using the DSC (differential scanning calorimetry) method.
Under these circumstances, the initial boiling point of the test item was stated between 218.22°C and 219.83°C (491.37K - 492.98K)
These values are the results from three independent determinations.

The validity criteria apply only if the test was determined using DSC.
Finally, the boiling of the substance was determined under these circumstances as the endothermic event as:
The boiling of the substance processes in a range between 166.03°C and 272.91°C (439.18K - 546.06K) with a lowest peak maximum of 228.30°C (501.45K).
A range of the onset between 218.22°C and 219.83°C (491.37K - 492.98K) is stated for the initial boiling point of the test item at an atmospheric pressure between 1001,2 and 1001,4 mbar.
These values are the results from three independent determinations.
Description of key information
The initial boiling point is stated between 218.22°C and 219.83°C at an atmospheric pressure between 1001,2 and 1001,4 mbar.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 218.22 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study.
