Table 1. Results of relative density of the test substance.

 Replicates

 Relative density 20/4
 1 0.9838 
 2 0.9821 
 3 0.9815 

The mean relative density (20/4) of the test substance was determined by average of three replicates: 0.9820 ± 0.0001.

Conclusions:
The mean relative density (20/4) of the test substance was determined by average of three replicates: 0.9820 ± 0.0001.
Executive summary:

The relative density of the test substance was carried out according to OECD 109 Guideline, no data on GLP. The determination of the relative density was performed by Pycnometer method according to ISO 758.

For the determination a calibrated glass Pycnometer Gay-Lussac type conforming to the dimension given in ISO 3507 was used to determine product density (following ISO 758). Nominal capacity: 25.073 cm3. Three replicates were performed.

The temperature was 20ºC. The Pycnometer was introduced in a water bath at 20ºC. The mean relative density (20/4) of the product was determined by average of three replicates: 0.9820 ± 0.0001.

Description of key information

Key study: OECD Guideline 109. The relative density (20/4) of the test substance was determinated to be 0.9820 ± 0.0001.

Key value for chemical safety assessment

Relative density at 20C:
0.982
