Conclusions:
The mean relative density of the test item is: D = 1.0024 at 24.4 °C.
Executive summary:

The objective of this study was to determine the Density of the test item 10-UNDECENOIC ACID applying the procedure described in the OECD Guideline 109 (study sithout deviations and under GLP). The pycnometer method was used. The mean relative density of the test item is: D = 1.0024 at 24.4 °C.

Description of key information
