Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

The boiling point was determined according to the Siwoloboff method.
The boiling point of terpinolene multiconstituent is 184°C +/- 5°C at 985 hPa .

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
184 °C

Additional information

Key study conducted according to OECD Guideline No.103 and EU Method A.2. The Siwoloboff method recommended for pure substances and mixtures in the OECD guideline does not allow to determine a boiling point range. It allows to approximate the boiling point of the main constituents with the lowest boiling point. This is considered as acceptable for the purpose of REACH registration. The result is thus scientifically acceptable but not obtained under GLP. A reliability of 2 (reliable with restrictions) is assigned to the study and the obtained value is used as key value for the chemical safety assessment.
