Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 500-446-0 | CAS number: 160901-09-7 1 - 2.5 moles ethoxylated
Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 29 March 2012
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Principles of method if other than guideline:
- The test is conducted to determine the temperature or temperature range of the phase transition from a solid to a liquid. The test also determines if the sample undergoes exothermic decomposition.
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Boiling pt.:
- 260 °C
- Atm. press.:
- 102.9 kPa
- Remarks on result:
- other: followed by decomposition
Reference
The test was conducted in an ‘open’ (pierced lid) aluminium crucible. The sample was observed to boil at 260 °C followed by decomposition. The contents of the crucible at the end of the test were not visible but a mass loss of 6 mg was observed. The test results indicate that the material boils at 260 °C before it decomposes. Atmospheric pressure is not reported - assumed normal pressure, ca. 1013 hPa.
Description of key information
260 °C at 102.9 kPa (boiling with decomposition) (EU Method A.2)
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 260 °C
Additional information
The boiling point of the substance was determined according to EU Method A.2 using differential scanning calorimetry. The sample was observed to boil at 260 °C followed by decomposition.
