Conclusions:
Under the study conditions, the relative density of test substance was determined to be 0.998.
Executive summary:

A study was conducted to determine the relative density of the test substance, C10-12 and C18-unsatd. DEA, using hydrostatic balance method, according to the OECD Guideline 109, in compliance with GLP. Under the study conditions, the relative density of test substance was determined to be 0.998 at 20.44 °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).

Key value for chemical safety assessment

Relative density at 20C:
0.998
