Description of key information
Appearance
The test item was observed to be a clear, colourless, liquid.
Melting/freezing point
The melting range of the test item was -16.2 to 9.1 °C (257.0 to 282.3K). A glass transition of the test item was observed at -55.0 °C (218.2K) (OECD 102. EU Method A.1 and OPPTS 830.7200).
Boiling point
Reaction and/or decomposition of the test item was observed during DSC experiments at temperatures of > 200 °C (> 473K) (OECD 103, EU Method A.2 and OPPTS 830.7220).
Relative density
The density of the test item was determined by the pycnometer method to be 0.919 g/cm3 (0.919 x 10E03 kg/m3) at 20 °C. Relative density was reported as 0.919.
Granulometry
Particle size influencing toxicological profile is irrelevant because the substance is a liquid at ambient temperature.
Vapour pressure
The vapour pressure of the test item was determined to be 3.1 x 10E-02 Pa at 20 °C (equivalent to 2.3 x 10E-04 mm Hg) and 5.7 x 10E-02 Pa at 25 °C (equivalent to 4.2 x 10E-04 mm Hg) (OECD 104, EU Method A.4 and OPPTS 830.7950).
Partition coefficient
Pow values at neutral pH were determined to be 2.1 x 10E+06 (peak 1; area 83 %) and 4.6 x 10E+6 (peak 2; area 17 %). The corresponding Log Pow values were reported as 6.3 (peak 1) and 6.7 (peak 2) (OECD 117, EU Method A.24 and OPPTS 830.7570).
Water solubility
Water solubility was determined by the slow-stirring flask method to be 0.420 mg/L at 20 °C and pH 7.5 (OECD 105, EU Method A.6 and OPPTS 830.7840).
Surface tension
The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 52.8 mN/m. According to this, the test item is considered to be surface active (OECD 115 and EU Method A.5).
Flash point
The flash point of the test item was determined by the closed cup equilibrium method to be 147°C (EU Method A.9 and ISO 2719).
Auto-ignition temperature
The test item is auto-ignitable with an auto-ignition temperature of 250 °C at 999 to 1004 hPa (EU Method A.15).
Flammability
The test item is a liquid and, in line with ECHA Guidance on Information Requirements and Chemical Safety Assessment Chapter R.7a: Endpoint specific guidance (Version 6.0; July 2017), relevant properties for classification of the substance as flammable are the determined flash point and boiling point. Further experimental investigation of flammability is therefore not required.
Flammability in contact with water
Expert opinion considers the test item to be not highly flammable in contact with water (EU Method A.12, UN Test N.5 and UN Appendix 6).
Pyrophoric propertie
The test item is considered to have no pyrophoric properties (EU Method A.23, UN Test N.3 and UN Appendix 6).
Explosive properties
The test item is considered to have no explosive properties (EU Method A.14, OPPTS 830.6316 and UN Appendix 6).
Oxidising properties
The test item is considered to have no oxidising properties EU Method A.21, UN Test O.2 and UN Appendix 6).
Additional information
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.
