Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 03 December 2003 to 06 January 2004
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Study in accordance with the Method A3 of Commission Directive 92/69/EEC. Purity and isomers composition specified.
according to guideline
EU Method A.3 (Relative Density)
Version / remarks:
Directive 92/69/EEC
according to guideline
OECD Guideline 109 (Density of Liquids and Solids)
Version / remarks:
27July 1995
GLP compliance:
yes (incl. QA statement)
Swiss GLP compliance programme (inspected on September 09 and 30, 2002/ signed on December 2002)
Type of method:
oscillating densitimeter
Specific details on test material used for the study:
- Physical state: liquid
- Storage condition of test material: refrigerator (0-10°C) under nitrogen
Dynamic viscosity of test material:
Applicability of the method is limited to liquids having a maximum dynamic viscosity of 5 Pa.s.
Viscosity of the test material is not specified, but the substance is described as slightly viscous (please refer to endpoint 4.1), therefore the method is assumed to be suitable.
Key result
relative density
0.921 other: corresponds to D20/4; relative density has no dimension
20 °C

Individual measurements: (1) 0.921, (2) 0.921, (3) 0.921.

The substance is much less dense than water.
Executive summary:

The relative density of the test substance was measured under GLP according to OECD 109 / EU A3 guideline, oscillating densitimeter method.

The measurements were made in triplicate at 20°C.

A mean relative density of 0.921 at 20°C was determined for the test material.

Description of key information

The substance is much less dense than water.

Key value for chemical safety assessment
