Description of key information

Relative density: 1.24 at 20 °C

Key value for chemical safety assessment

Relative density at 20C:
1.24

Additional information

A relative density value of 1.24 at 20 °C was determined during tests according to EU Method A.3. Bulk density values of 0.67 g/mL (poured) and 0.69 g/mL (tapped) were determined using a Dry Substance Jolting Volumeter according to CIPAC MT186 “Bulk Density” CIPAC Handbook Volume K, Analysis of Technical and Formulated Pesticides. The difference between the relative density and the bulk density values could be attributed to different degrees of compaction.
