Description of key information

Additional information



The test item was observed to be a pale amber liquid during performance of GLP guideline studies.


Melting/freezing point


The pour point of the test item was determined to be 0 ± 3 °C (273 ± 3 K) (OECD 102 and EU Method A.1).


Boiling point


The test item partially volatilised from approximately 278 °C (551 K) at 101 kPa. Approximately 25 % of the test material did not volatilise up to 400 °C (OECD 103 and EU Method A.2).


Relative density


Density was determined to be 922kg/m3 at 20.0 ± 0.5°C with a relative density of 0.922 (OECD 109 and EU Method A.3).



The test item is a liquid and determination of particle size distribution is not relevant.


Vapour pressure


The vapour pressure of the test item has been determined to be 1.3E-02 Pa at 25 °C (directly measured) and 0.95 Pa at 75 °C (directly measured), using the vapour pressure balance method (OECD 104 and EU Method A.4).

Partition coefficient


Experimental determination of partition coefficient was not possible because the test item is a complex, surface active, UVCB where the components exist as ion pairs. Log Kow for the environmentally relevant constituent of the test item was therefore predicted using EPISUITE (KOWWIN v1.68). The Log Kow calculated was 5.14.


Water solubility


Water solubility of the test item at 20.0 ± 0.5 °C was determined to be 0.00934 g/L equivalent test item based on phosphorus concentration and 0.0135 g/L equivalent test item based on total organic carbon (OECD 105 and EU Method A.9).


Surface tension


The surface tension of test item prepared at 90 % saturation in water was determined to be 50.0 mN/m at 21.0 ±°C. The test item was considered to be surface active (OECD 115 and EU Method A.5).

Flash point


The flash point of the test item has been determined to be 128 ± 2 °C (EU Method A.9).


Autoflammability / self-ignition temperature


The test item has been determined to have an auto-ignition temperature of 308 ± 5 °C (EU Method A.15).




A flash point determination has been performed to fulfil the requirement for information on flammability of the substance. The flash point of the substance is 128 ± 2 °C at 101 kPa. Based on experience in use, the substance is not pyrophoric and does not emit flammable gases in contact with water.

Explosive properties


Based on the chemical structure of the test item the result for the explosive properties has been predicted negative (EU Method A.14).


Oxidising properties


Based on the chemical structure of the test item the result for the oxidizing properties has been predicted negative (EU Method A.21).
