The density of Test Item was found to be 0.9951 g/cm3 at 20 ± 1°C. The Relative Density  (D²⁰₄) of the Test Item is 0.9951.

Conclusions:

The density of test Item was found to be 0.9951 g/cm3 at 20 ± 1°C. The Relative Density of the Test Item is 0.9951.

Executive summary:

The relative density of Vetimoss was tested using a density meter and according to OECD 109 guidance. The density of Test Item was found to be 0.9951 g/cm3 at 20 ± 1°C. The Relative Density  (D²⁰₄) of the Test Item is 0.9951.

Description of key information

The relative density of Vetimoss was tested using a density meter and according to OECD 109 guidance. The density of Test Item was found to be 0.9951 g/cm3 at 20 ± 1°C. The Relative Density  (D²⁰₄) of the Test Item is 0.9951.

This is further aupported by company data which specifies that the density of the test material 2-tert-butyl-1,4-dimethoxybenzenes is 0.994-0.996 g/mL at 20°C.
