Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 232-350-7 | CAS number: 8006-64-2 Any of the volatile predominately terpenic fractions or distillates resulting from the solvent extraction of, gum collection from, or pulping of softwoods. Composed primarily of the C10H16 terpene hydrocarbons: α-pinene, β-pinene, limonene, 3-carene, camphene. May contain other acyclic, monocyclic, or bicyclic terpenes, oxygenated terpenes, and anethole. Exact composition varies with refining methods and the age, location, and species of the softwood source.

temperature: 19°C
Atmospheric pressure: 99.44 to 99.52 kPa
Description of key information
Auto flammability: 270°C at 99.44 - 99.52 kPa (EU Method A.15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:

Additional information
A reliable auto-ignition temperature value of 270°C at 99.44 - 99.52 kPa has been determined for the test substance in accordance with an appropriate test method and in compliance with GLP. The result is considered to be reliable. Auto-ignition is not expected to present a hazard for the test substance.
