The boiling point was determined to be 257 °C at 1013.25 hPa.

 

Density

The relative density of the test item was determined to be 1.032 at 20 °C with respect to water at 4 °C.

 

Particle size distribution (Granulometry)

This physical chemical property is not applicable to the test item as the substance is a liquid at room temperature.

 

Vapour pressure

The vapour pressure of the test item was calculated by extrapolation of the measured vapour pressure curve for the temperatures 20, 25 and 50 °C, according to Regulation EC No. 440/2008 Method A.4. Vapour Pressure. Vapour pressure of the test item was determined to be 0.08, 0.12, 0.74 hPa at temperatures of 20, 25, 50 °C, respectively.

 

Partition coefficient

The partition coefficient log Pow of the test substance was determined to be log Pow = 2.4 at 35 °C.

 

Water solubility

The water solubility of the test item was determined to be 742 mg/L at 20 ± 0.2 °C.

 

Surface tension

The surface tension of an aqueous solution of the test item was determined to be 53.6 mN/m.

 

Flash point

The flash point was determined to be 102.0 °C at 1013.25 hPa.

 

Auto flammability

The auto-ignition temperature of the test item was determined to be 450 °C ± 10 °C at 1013.25 hPa.

 

Flammable solid

The test item is a liquid a room temperature. Thus an allocation in this hazard class is not applicable.

 

Flammable liquid

The test on the flammability (Regulation (EC) No 440/2008 method A.10) was not performed as the test item is a liquid. For liquids the primary value for ease of ignition is the flash point conducted using Method A9 ‘Flash Point Method’ of Council Regulation (EC) No 440/2008. The result of the Flash Point test is used to allocate a liquid substance into the appropriate flammability class. The flash point was determined to be 102.0 °C at 1013.25 hPa (please refer to IUCLID section 4.11).

With a measured flash point > 60 °C, the test item does not have to be classified as flammable liquid according to GHS or CLP Regulation EC 1272/2008 Annex 1.

 

Flammable gases

The test item is a liquid a room temperature. Thus an allocation in this hazard class is not applicable.

 

Pyrophoric solid

The test item is a liquid a room temperature. Thus an allocation in this hazard class is not applicable.

 

Pyrophoric liquid

In accordance with section 2.9.4 Annex I of Regulation (EC) No 1272/2008 and ECHA guidance on the application of CLP Criteria section 2.10.4.2 the classification procedure for pyrophoric liquids need not to be applied when experience in manufacturing or handling shows that the substance or mixture does not ignite spontaneously when coming into contact with air at normal temperatures. Based on the experience in handling and use the substance is not known to ignite spontaneously when coming into contact with air at normal temperatures. Thus, no study was conducted and consequently the substance has not to be considered for classification as pyrophoric liquid.

 

Substances which, in contact with water, emit flammable gases

In accordance with column 2 of REACH Annex VI and with Regulation (EC) No 1272/2008 Annex I section 2.12.4.1 the classification procedure for this hazard class need not be applied if:

a) The chemical structure of the substance or mixture does not contain metals or metalloids; or

b) Experience in handling and use shows that the substance or mixture does not react with water, e.g. the substance is manufactured with water or washed with water; or

c) The substance or mixture is known to be soluble in water to form a stable mixture.

The substance did not contain metals or metalloids. Therefore the substance has not to be considered for classification as substances which, in contact with water, emit flammable gases.

 

Self-heating substances and mixtures

In accordance with ECHA guidance on the Application of the CLP Criteria section 2.11.4.2 and ECHA guidance on IR/CSA chapter R.7a section R7.1.10.7 the test does not to be conducted as in general liquids are not classified as self-heating since the phenomena applies only to solids. Furthermore the test method is not applicable to liquids according to guidance on the Application of the CLP Criteria section 2.11.4.2. Thus no classification procedure for self-heating substances and mixtures was required and consequently and the substance has not to be considered for classification as self-heating substances and mixtures.

 

Flammable Aerosols

Section 2.4.2 of Guidance on the application on the CLP Criteria state as follows:

“Aerosols, this means aerosol dispensers, are any non-refillable receptacles made of metal, glass or plastics and containing a gas compressed, liquefied or dissolved under pressure, with or without a liquid, paste or powder, and fitted with a release device allowing the contents to be ejected as solid or liquid particles in suspension in a gas, as a foam, paste or powder or in a liquid state or in a gaseous state. Thus, as the substance does not meet the definition for aerosol, the test for aerosols was waived. Consequently the substance has not to be considered for classification for this hazard class.

 

Explosiveness

Based on the chemical structure it was concluded that the substance has no to be considered for classification for explosiveness.

 

Oxidising properties

Based on the chemical structure it was concluded that the substance has no to be considered for classification for oxidising properties.

 

Stability in organic solvents and identity of relevant degradation products

The stability in organic solvents of the test item was not considered as critical.

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 peroxide

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

In accordance with Regulation (EC) 1907/2006 Annex XI the UN test C.1 does not need to be conducted as the pH value of the substance is greater than 4 and less than 10 and there is no halogen in the molecule.

 

Gases under pressure

The study does not need to be conducted because the substance is a liquid under ambient conditions.
