FAT 40000 is a yellow powder at 20 °C.

The test substance FAT 40000 when tested according to OECD Guideline 102 for melting point and OECD Guideline 103 for boiling point determination did not melt or boil until 350 °C.

Average relative density of FAT 40000 TE at 20 °C was found to be 1.6841 g/cm³.

The median particle size of FAT 40000 was 161.306 µm.

The partition co-efficient n-octanol/water of FAT 40000 at 20 °C was determined to be Pow = 1.99E-6, Log Pow = -5.70.

The water solubility of FAT 40000 at 20 °C was determined to (without correction for the purity): = 366 g/l.

The surface tension of FAT 40000 was determined to be 67.199 mN/m at 20 °C.

The auto-ignition temperature of FAT 40000 cannot be determined, as no auto-ignition occurred up to 550 °C.

No ignition was observed throughout the course of a flammability study with FAT 40000, 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.
