Conclusions:
The relative density value of the d-phenothrin pure active substance was found to be 1.06 g/mL as average of three measurements.
Executive summary:

The relative density of the test material "d-phenotrin pure active substance" has been tested according to the following guidelines CIPAC MT 3.2, EU A3, OECD 109).

Since it was not possible to use the pycnometers, due to the small test article amount available (20 g), a 10 mL volumetric flask was employed to obtain a representative density value at 20 °C. The relative density value of the d-phenotrin pure active substance was found to be 1.06 g/mL as average of three measurements.

Description of key information

The relative density value of the d-phenothrin pure active substance was found to be 1.06 g/mL as average of three measurements in a study according to OECD 109 guideline.

Key value for chemical safety assessment

Relative density at 20C:
1.06
