FAT 40061 is a yellow powder, solid at 20 °C

The test substance FAT 40061 when tested according to OECD test guideline 102 for melting point and OECD test guideline 103 for boiling point determination did not melt or boil until 350 °C. But around 280°C the test substance begin thermic decomposition.

Average relative density of FAT 40061/F TE at 20 °C was found to be1.3126 g/cm³.

The particle size data of FAT 40061/F were as follows:

Percentage of test item with an inhalable particle size <100 µm (Sieve Method): 95.9 %

Percentage of test item with a thoracic particle size <10.0 µm (Cascade Impactor): 0.27 %

Percentage of test item with a respirable particle size <5.5 µm (Cascade Impactor): 0.17%

The partition co-efficient n-octanol/water of FAT 40061 at 20 °C was determined to: Pow = 0.0000183, Log Pow = -4.74.

The water solubility of FAT 40061/F at 20 °C was determined to (without correction for the purity): =197 g/l

The surface tension of FAT 40061/F was determined to be 44.848 mN/m at 20 °C.

The auto-ignition temperature of FAT 40061/F is - No auto-ignition up to 550 ° C.

No ignition was observed throughout the course of FAT 40061/F, hence it is considered as not highly flammable.

The analysis of the chemical structure reveals no alerts for explosive properties. The calculated chemical oxygen balance is above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release below the critical value of 500 J/g. Therefore the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing are required.

In accordance with Column 2 of REACH Annex VII, this study does not need to be conducted as this substance is incapable of reacting exothermically with combustible materials on the basis of its chemical structure.
