Endpoint summary

Description of key information

Appearance

The substance is an odourless dark brown viscous liquid.

Melting / Freezing point

The pour point of the test substance, as determined by ASTM D97-09, is -6 °C.

Boiling point

The substance is a liquid which undergoes decomposition before boiling.

Density

The density of the test substance, determined by procedures given in ASTM D4052-09, is 0.9925 g/mL at 15.6 °C.

Granulometry

Determination of particle size distribution is not relevant because the substance is a viscous liquid.

Vapour pressure

The vapour pressure of the test item determined in accordance with EU Method A.4 and OECD Guideline 104 was 3.5 x 10E-04 Pa at 25 °C and 0.05 Pa at 70 °C.

Partition coefficient

The partition coefficient of the test item has been determined to be > 2.51E+09, Log Pow > 9.4. By extrapolation of the calibration curve using the mean retention time of 85.174 minutes, the log Pow is > 11.7 (OECD 117 and EU Method A.8).

Water solubility

The water solubility of the substance is less than 4.93 mg/L at 20 °C (OECD 105 and EU Method A.6).

Surface tension

Surface activity could not be determined (OECD 115 and EU Method A.5).

Flash point

The flash point of the substance is > 240 deg. C at 760 mmHg (equivalent to 101325 Pa) using the closed cup method (ISO 2719:2002). The liquid substance is not flammable.

Autoignition temperature

The autoignition temperature is 381 °C at atmospheric pressure (ASTM E659).

Aerosols

Consideration of the test item as an aerosol is not required because the substance is not supplied in aerosol dispensers.

Flammable gases (including chemically unstable gases)

Consideration of the test item as a flammable gas is not required because the substance is a liquid).

Flammable solids

A flash point determination has been performed to fulfil the requirement for information on flammability of the substance. The flash point of the substance was determined to be > 240 °C at 760 mm Hg (equivalent to 101325 Pa). Based on experience in use, the substance is not pyrophoric and does not emit flammable gases in contact with water.

Pyrophoric liquids

The study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied.

Pyrophoric solids

Consideration of the test item as a pyrophoric solid is not required because the substance is a liquid.

Self-heating substances

The study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied.

Substances which in contact with water emit flammable gases

The study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture.

Explosive properties

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.

Desensitised explosives

Consideration of the test item as a desensitised explosive is not required because the substance is not explosive and is not placed on the market wetted with water or alcohols or diluted with other substances to suppress explosive properties.

Oxidising gases

Consideration of the test item as an oxidising gas is not required because the substance is a liquid.

Oxidising liquids

Experimental investigation of the substance as an oxidising liquid is not required because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied.

Oxidising solids

Consideration of the test item as an oxidising solid is not required because the substance is a liquid.

Stability in organic solvents and identity of relevant degradation products

The test substance was determined to be stable in arachis oil for 14 days (procedures associated with OECD 408).

Thermal decomposition

Thermal decomposition and overall weight loss onset occurs at 324 ˚C, excluding minimal solvent content (Thermogravimetric analysis).

Dissociation constant

The study is considered inappropriate because the substance has been determined to be no more than slightly soluble in water.

Viscosity

Viscosity of the test substance was determined to be 1846 mm2/s at 40 °C (ASTM D445-10).

Aspiration hazard

The test item is liquid at 40 °C. However, it is not a hydrocarbon with a kinematic viscosity of ≤ 20.5 mm2/s and consideration of the substance as an aspiration hazard is not required.

Self-reactive substances

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive or self-reactive properties and hence, the classification procedure does not need to be applied.

Organic peroxides

The study does not need to be conducted because the substance does not fall under the definition of organic peroxides according to GHS and the relevant UN Manual of tests and criteria.

Corrosive to metals

The substance is a viscous liquid. However, testing for corrosion to metals is not a standard REACH endpoint, and experience in handling and use demonstrates that the substance does not materially damage or destroy metals. Further investigation is therefore considered unnecessary.

Gases under pressure

Consideration of the test item as a gas under pressure is not required because the substance is a liquid.
