The relative density and the bulk density are 960 and 600 g/l resp.
The difference in bulk and relative density
differ considerable and is due to the production process of the Tonalid
(AHTN). Since AHTN melts around 54oC, the relative density
can be determined by melting the AHTN prior to the determination.
Strictly speaking, the relative density should be between 600 and 960
g/l, but it should be closer to the molten density than to the bulk
density. Hence the 960 g/l has been taken forward in the registration as
the relative density.
The relative density is less than one
and the water-solubility of AHTN very low. Consequently, the substance
is likely to float, which is relevant information for the risk
