Conclusions:
Under study conditions, the relative density of the test substance was determined to be 0.86.
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 of GLP. Under study conditions, the relative density of the test substance was determined to be 0.86 (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).
