Description of key information

Additional information

Physical State: The substance MAHP is a clear colourless liquid at room temperature which is slightly viscous.

Pour Point: The pour point of the test material has been determined to be 280 ± 3 K.

Boiling Temperature: The test material has been determined to decompose from approximately 389 ± 0.5 K at 101.31 kPa. As the test material decomposed, no value for boiling temperature could be determined. A calculated value of boiling temperature gave a result of greater than 633 K at 101.325 kPa.

Relative Density: The relative density of the test material has been determined to be 1.20 at 20.0 ± 0.5°C.

Particle Size Ditribution (Granulometry) (Waived): In accordance with Column 2 adaptation (Annex VII, section 7.14) of REACH Regulation 1272/2008, the study does not need to be conducted if the substance is marketed or used in anon-solid or granular form. The submission substance is a liquid and therefore this study is deemed inappropriate.

Vapour Pressure: The vapour pressure of the test material has been determined to be 4.1 x 10-3 Pa at 25°C, using method A4.

Partition Coefficient: Partition Coefficient was determined to be 45.6 (log10 Pow 1.66). As the value for partition coefficient is < 4, this means the substance is unlikely to accumulate in the environment.

Water Solubility: Water Solubility was determined to be 9.67 g/l of solution at 20.0 ± 0.5°C.

Surface Tension: The surface tension of a 1.05 g/l solution of test material has been determined to be 60.7 mN/m at 22.4 ± 0.5°C. The test material is considered not to be a surface-active material.

Flash Point: The flash point of the test material has been detennined to be 159 ± 2°C.

Auto Flammability: The test material has been determined to have an auto-ignition temperature of 384 ± 5°C.

Flammability: The study is normally conduted for solids. As the submission substance is a liquid a flash point is preferred instead. See section 4.11 (Flash point).

Explosiveness: Based on the chemical structure ofthe test material the result for the explosive properties has been predicted negative.

Oxidising Properties: Based on the chemical structure the result for the oxidising properties has been predicted negative.
