Description of key information
Additional information
Terpinolene multiconstituent is a yellow liquid at ambient temperature. It is classified as Flammable Liquid Category 3 according to Regulation No. 1272/2008 (CLP) and as Flammable R10 according to Directive 67/548/EEC (DSD). Terpinolene multiconstituent does not contain chemical groups associated with explosivity or oxidising properties.
The main physical and chemical properties of this substance are given below.

| Water solubility* | 1015.6 mg/L at 20°C |
| Flash point | 53°C at atmospheric pressure (closed cup) |
| Auto-ignition temperature | 250°C at 986 hPa |
| Viscosity | 1.89 mPa.s at 20°C (shear rate = 583 s-1) and 1.25 mPa.s at 40°C (shear rate = 583 s-1) |
* The water solubility of terpinolene multiconstituent was calculated as the sum of the mean measured concentration of each of the main constituents of the substance (terpinolene, 1,8-cineole, 1,4-cineole) and of the main impurities (dl-limonene) for a loading rate of 34.3 g/L.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
