Relative density D20/4:

Experiment 1: 1.049

Experiment 2: 1.033

Mean: 1.04

Conclusions:

The relative density D20/4 of the substance was determined to be 1.04.

Executive summary:

The density of the substance was determined at 20°C using a gas comparison pycnometer in a GLP study according to EC A.3, OECD 109 and OPPTS 830.7300. The relative density D20/4 was determined in duplicate obtaining a mean value of 1.04.

Description of key information

Relative density D20/4: 1.04 (EC A.3, OECD 109, OPPTS 830.7300: gas comparison pycnometer).

Key value for chemical safety assessment

Relative density at 20C:
