Conclusions:
Under study conditions, the relative density of the test substance was determined to be 0.98138 at 20.4°C.
Executive summary:

A study was conducted to determine the density of the test substance using the hydrostatic balance method, according to OECD Guideline 109, in compliance with GLP. Under study conditions, the relative density of the test substance was determined to be 0.98138 at 20.4°C (Scymaris, 2017).

Description of key information

The relative density of the test substance was determined using the hydrostatic balance method, according to OECD Guideline 109 (Scymaris, 2017).
