Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Mean value of density [g/cm3]

1.3417

1) calculated from the masses

2) known from calibration

3) calculated from the mass of the test item and volume of the pycnometer

The relative density D420 is: 1.3417 g/cm3: 0.99997 g/cm3 = 1.3417

(0.99997 g/cm3as density of water at 4°C)

Conclusions:
A relative density value of 1.3417 at 20°C was determined for the substance using a relevant test method. The result is considered reliable.

Description of key information

Relative density: 1.3417 at 20°C (OECD 109)

Key value for chemical safety assessment

Relative density at 20C:
1.342

Additional information

A measured relative density value of 1.3417 at 20°C was determined for the registration substance using pycnometer method in accordance with OECD Test Guideline 109 and in compliance with GLP. The result is considered to be reliable and selected as key study.

 

In a secondary source to which reliability could not be assigned, a density value of 1.334 g/cm3 at 20°C was reported for the substance.
