Description of key information
Appearance
The test material was observed to be a dark brown paste.
Melting/freezing point
The melting point of the test item was determined to be over the range 26 to 53 °C (299 to 326 K) using differential scanning calorimetry (OECD 102 and EU Method A.1).
Boiling point
The test item was determined by differential scanning calorimetry to decompose from approximately 183 °C (456 K) at 98 kPa (OECD 103 and EU Method A.2).
Relative density
The density of the test item was determined using a gas comparison pycnometer to be 932 kg/m3 at 20.5 ± 1.0 °C and the relative density was reported as 0.932 (OECD 109 and EU Method A.3).
Granulometry
Granulometry was not investigated because the test item is a paste with determined melting temperature of 26 to 53 °C (299 to 326 K). Particle size influencing toxicological profile is irrelevant because the substance is on the border between the solid and liquid state at ambient temperature. Furthermore, the determined vapour pressure of 1.91 Pa at 25 °C (298 K) indicates that exposure of humans to the test item via the inhalation route is of low concern under general operating conditions at ambient temperature.
Vapour pressure
The vapour pressure of the test item was determined by the balance method to be 1.91 Pa at 25 °C (298 K), 13.0 Pa at 82 °C (355 K) and 18.8 Pa at 88 °C (361 K) (OECD 104 and EU Method A.4).
Partition coefficient
The partition coefficient of the test item was determined by the HPLC method to be > 1.0 x 10E10 with Log10 Pow > 10.0 (OECD 117 and EU Method A.8).
Water solubility
The water solubility of the test item was determined using the flask method and a nominal loading rate of 0.1 g/L to be 4.34 x 10E-03 gTOC/L at 20.0 ± 0.5 °C (OECD 105 and EU Method A.6).
Surface tension
The surface tension of solutions prepared at nominally 90 % saturation of test item in water was determined by the ring method to be 58.8 ± 0.5 mN/m at 20.0 ± 0.5 °C. The substance was considered to be surface active (OECD 115 and EU Method A.5).
Flash point
The flash point of the test item was determined to be 78 ± 2 °C using the closed cup equilibrium method (EU Method A.9).
Autoflammability / self-ignition temperature
The test item was determined to have an autoignition temperature of 362 ± 5 °C at 100.6 to 102.3 kPa (EU Method A.15).
Flammability
The test item was determined to be not highly flammable as it failed to ignite in the preliminary screening test (EU Method A.10).
Explosive properties
The result for explosive properties was predicted negative based on the chemical structure of the test item (EU Method A.14).
Oxidising properties
The result for oxidising properties was predicted negative based on the chemical structure of the test item (EU Method A.17).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.
