Appearance/Physical state/Colour

The test item is a light beige solid as reported in the test item section, and associated certificate of analysis, in a GLP-compliant experimental study (2018).

 

Melting point/freezing point

The melting point of the test item was determined to be ≥ 300 ⁰C by the capillary method (2018). The study was conducted according to OECD 102 guideline.

 

Boiling point

The boiling point was waived as in accordance with column 2 of REACH Annex VII, the boiling point study does not need to be conducted as this substance is a solid which melts above 300°C. 

 

Density

Particle size distribution

This endpoint was waived as in accordance with column 2 of REACH Annex VII, the granulometry study does not need to be conducted as the substance is marketed or used in a non-solid or granular form.

 

Vapour pressure

The vapour pressure was waived as in accordance with column 2 of REACH Annex VII, the vapour pressure study does not need to be conducted as this substance is a solid which melts above 300°C. 

 

Partition coefficient

The log Pow value was determined to be 3.21 (2018). The partition coefficients were determined by HPLC method according to OECD TG 117.

 

Water solubility

The water solubility of the test item was determined to be 707.602 mg/L based on azelaic acid and 53.862 mg/L based on lithium at 18.9±2.1°C (2019). Water solubility was tested according to OECD TG 105.

 

Surface tension

The surface tension of the test item is 52.9 mN/m. The study was performed according to the OECD 115 guideline using the ring method (2018).

 

Flash point

The flash point was waived as in accordance with ECHA (2014) guidance on information requirements and chemical safety assessment, chapter R7a: endpoint specific guidance, the flashpoint study does not need to be conducted as this substance is considered to be a solid at room temperature.

 

Auto flammability

The auto-ignition temperature of the test item was determined to be 206°C (2018). This study is GLP and follows a standard test guideline (EU method A16) and is reliable without restrictions.

 

Flammability

The test item is considered to not be highly flammable based on the study following method A.10 -Flammability (Solids) (2018). 

Explosiveness

This endpoint was waived as in accordance with column 2 of REACH Annex VII, the explosive properties study does not need to be conducted as there are no chemical groups associated with explosive properties present in the molecule.

 

Oxidising properties

This endpoint was waived as in accordance with column 2 of REACH Annex VII, the oxidising properties study does not need to be conducted 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.
