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.

Description of key information
Flash point: 5°C (EU Method A.9)
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 5 °C
Additional information
Several flash point studies conducted in accordance to an appropriate test guideline and in line with GLP are available for different samples of the test substance. Flash point values of 5°C, 26°C and 37°C have been determined for the samples tested. It is also possible to obtain a flash point value lower than 5°C in some samples of the substance. Turpentine Oil from Pulping Processes (TOPP) is a UVCB substance and the variations in the results could be due to the nature or composition of the samples tested.
TOPP is therefore classified as flammable/highly flammable liquid, however, it is not expected that the substance will be pyrophoric or release flammable gas in contact with water.
A flash point of 5 -37°C and boiling point of 154 -170°C indicate that TOPP should be classified as a flammable/highly flammable liquid in accordance with Regulation (EC) No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
