Endpoint summary

Description of key information

Appearance

The test material is a waxy solid coloured off-white at room temperature.

Melting point

The test substance has a melting range of 53 - 58 °C at atmospheric pressure (OECD 102 and EU Method A.1).

Boiling point

The test material does not boil at temperatures up to and including 400 °C at 100.9 kPa (OECD 103 and EU Method A.2).

Density

The density of the test material is 975 kg/m3 at 22.5 °C (OECD 109 and EU Method A.3).

Granulometry

The substance is a hydrophobic waxy solid. It is imported into the EU diluted in a solvent. It is not sold or marketed in a solid or granular form.

Vapour pressure

The vapour pressure of the test item has been determined to be 9.0E-03 Pa at 25°C (OECD 104 and EU Method A.4).

Octanol/water Partition Coefficient

The log Pow value of the test material is 6.24 to > 9.4 (OECD 117 and EU Method A.8).

Water Solubility

The water solubility of the test substance is less than or equal to 0.17 mg/L at 20°C (pH 4.4) (OECD 105 and EU Method A.6).

Surface tension

The study does not need to be conducted because water solubility is below 1mg/L at 20 °C.

Flash point

The flash point of the test material is 179 °C (EU Method A.9).

Autoflammability

The test material has an auto-ignition temperature of 350 ± 5 °C when tested as a liquid (EU Method A.15). The test material does not have a relative self-ignition temperature below its melting temperature when tested as a solid (EU Method A.16).

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 solid.

 

Flammable solids

The test item is determined to be not highly flammable as it failed to ignite in the preliminary screening test (EU Method A.10).

 

Pyrophoric liquids

The study does not need to be conducted because the substance is a solid.

 

Pyrophoric solids

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.

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 has a known solubility in water and forms a stable mixture.

Explosive properties

Based on the chemical structure of the test item the result for the explosive properties has been predicted negative.

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 requiredbecause the substance is a solid.

 

Oxidising liquids

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

Oxidising solids

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

Stability in organic solvents and identification of degradation products

The test substance is stable as a solution in peanut oil for 10 days.

Dissociation constant

The dissociation constants in water test is not applicable to complex mixtures. The test item had very low solubility in water. There were no dissociation constants within the environmentally relevant pH range and the limitations of the test methods.

Viscosity

Investigation of test item viscosity is not required because the substance is a solid.

Aspiration hazard

The test item is expected to be partially liquid at 40 °C. However, the substance not understood to be a hydrocarbon with a kinematic viscosity of ≤ 20.5 mm2/s and experimental investigation of aspiration hazard is not a standard REACH requirement.

 

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 low melting point solid that could theoretically become liquid during transport. 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 solid.
