Conclusions:
The freezing point of d-Tetramethrin is -8.3 °C.
Executive summary:

The freezing point of d-tetramethrin (technical grade) has been determined according to test Method A.1 – Melting/Freezing Temperature of Council Regulation (EC) No. 440/2008, Published in O.J. L 142, 2008, according to the Differential Scanning Calorimetry (DSC) technique. The analysis is performed with the sample as is with this heating program:

·        -20 °C for 5 minutes, then

·        from -20 °C to +35 °C, 10 °C/min heating rate.

The freezing point of d-Tetramethrin is –8.3 °C.
