Description of key information

Dilauroyl peroxide is classified as a peroxide Type D. Self-Accelerating Decomposition Temperature (SADT) of the substance is 50°C.

Dilauroyl peroxide consitsts of white flakes with a faint odour, so it is not an aerosol or a gas.

The relative density of di-lauroyl peroxide is 1.04.

The particle size distribution (PSD) of dilauroyl peroxide is: < 100 µm 1.4 %, < 10 µm 0.21% and < 5 µm 0.09%. The shape of the fines is non-fibrous.

The vapour pressure of dilauroyl peroxide at 20°C is 1.6 x 10-4 Pa.

The partition coefficient Log Pow of dilauroyl peroxide is > 6.5.

The water solubility of dilauroyl peroxide is less than 0.1 mg/l at 20°C and a pH of ca. 7. 

Flammability is an intrinsic hazard of organic peroxides.

Dilauroyl peroxide has no explosive and oxidizing properties.

Thermal stability of Dilauroyl peroxide expressed as the time to reach a conversion of 1% at 20°C is:

5.7 days for Dilauroyl peroxide dissolved in heptane

2.9 days for Dilauroyl peroxide dissolved in chlororform

1.6 days for Dilauroyl peroxide dissolved in acetone

 The study on corrosion towards metal is technically not feasible.
