Description of key information

The test item is a white solid having no melting point before decomposition starts at > 400 °C. A relative density of 2.108 at 20 °C was determined for the non-flammable solid that has a self-ignition temperature of 374 °C at atmospheric pressure.

The following water solubilities of the test item´s constituents at 20 °C and a pH of 4.9 were determined:

- Strontium 4,5-dichlorophthalate: 442.0 mg/L

- Strontium 3,4-dichlorophthalate: 5641.5 mg/L

- Strontium 3,6-dichlorophthalate + Strontium 4-chlorophthalate: 1163.5 mg/L

- Strontium 3,4,5-trichlorophthalate + Strontium 3,4,6-trichlorophthalate: 430.2 mg/L

Further, the following log Pow values were reported for the test item´s constituents:

- Strontium 4,5-dichlorophthalate = 1.9

- Strontium 3,4-dichlorophthalate = 1.1

- Strontium 3,6-dichlorophthalate and Strontium 4-dichlorophthalate = 0.9

- Strontium 3,4,6-trichlorophthalate and Strontium 3,4,5-trichlorophthalate = 2.0

Finally, the mean values of the particle size distribution of the test item out of three determinations are presented below:

- Mean of the particle size D10: 1.86 ± 0.03 µm

- Mean of the particle size D16: 2.68 ± 0.04 µm  

- Mean of the particle size D50: 8.81 ± 0.29 µm

- Mean of the particle size D84: 219.46 ± 7.33 µm

- Mean of the particle size D90: 304.33 ± 4.69 µm
