boiling point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
26 Jan-10 Feb 2012
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
OECD Guideline 103 (Boiling point/boiling range)
Principles of method if other than guideline:
In-house test procedure VTA(S)31X93002.02: "Boiling temperature determination(Tb) of solid and liquid substances by means of DSC"
GLP compliance:
Type of method:
differential scanning calorimetry
Boiling pt.:
ca. 187 °C
Atm. press.:
1 036 hPa
Decomp. temp.:
ca. 187 °C
Remarks on result:
other: possibly decomposition during boiling

A defined value for the boiling point of test item Alcohols, C10 -12, Ethoxylated (EO < 2.5) could not be determined based on the effects observed in the DSC experiments. The DSC curve, i.e. the peak shape and peak magnitute, indicates boiling and/or thermal decomposition starting at ca. 187 °C (at 1036 hPa).

190 °C (from first measurement)

185 °C (from second measurement)

187 °C (from third measurement)

192 °C (from fourth measurement)

182 °C (from fifth measurement)

Description of key information

boiling and/or thermal decomposition starting at ca. 187 °C at 1036 hPa (OECD 103, DSC)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
187 °C

Additional information

The boiling point of the substance was determined with differential scanning calorimetry according to OECD Guideline 103. The DSC curve shows various effects attributed to boiling and/or thermal decomposition starting at ca. 187 °C (at 1036 hPa).
