Conclusions:

MTDID 28640 has a pour density of 0.48 g/cm3, and a tap density of 0.58 g/cm3, both at 23.3 °C, determined according to OECD TG 109.

Executive summary:

The pour density of MTDID 28640 is 0.48 g/cm3, its tap density is 0.58 g/cm3, both at 23.3 °C. This study was conducted according to OECD TG 109 and was GLP compliant, therefore the results are considered reliable without restrictions and suitable for Risk Assessment, Classification and Labelling.

Conclusions:

MTDID 28640 has a density of 1.12 g/cm3 at 20°C, determined according to the DIN 53217 standard.

Executive summary:

MTDID 28640 has a density of 1.12 g/cm3 at 20°C, determined according to the DIN 53217 standard. This result was reported on the MSDS, and other than the name of the standard, no further information was provided. This standard allows for density determination via several methods such as bulk density, tap density, and the immersed body method, which is preferred. Since the specific method is unknown, the reliability of the data is not assignable.

Description of key information

MTDID 28640 has a pour density of 0.48 g/cm3, and a tap density of 0.58 g/cm3, both at 23.3 °C, determined according to OECD TG 109.

Additional information

In the key study, the pour density of MTDID 28640 was measured to be 0.48 g/cm3, and its tap density was measured to be 0.58 g/cm3, both at 23.3 °C. This study was conducted according to OECD TG 109 and was GLP compliant, therefore the results are considered reliable without restrictions and suitable for Risk Assessment, Classification and Labelling.

A density of 1.12 g/cm3 at 20°C, was also reported on a Safety Data Sheet which cited the DIN 53217 standard. This standard allows for density determination via several methods such as bulk density, tap density, and the immersed body method, which is preferred. However the type of density determination was not reported on the Safety Data Sheet, and since the study report was not available for review, the reliability of the data is not assignable.
