Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Experimental dates: 22 March 2019 to 23 May 2019
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Remarks:
The study was conducted according to an internationally recognised method, and under GLP. No deviation affected the quality of the study. The substance is adequately identified, but some data on composition is missing. Therefore validation applies with restrictions.
Qualifier:
according to guideline
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Version / remarks:
2012
Deviations:
no
Qualifier:
according to guideline
Guideline:
EU Method A.3 (Relative Density)
Version / remarks:
Commission Regulation (EC) No 440/2008
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Remarks:
issued 01/08/2019
Type of method:
pycnometer method
Dynamic viscosity of test material:
The usual procedure for liquids is suitable for those with dynamic viscosity less than 500 Pa.s. The viscosity value of the test item was not available, but it was visually considered suitable for measurement.

The duplicate determinations fell within the estimated accuracy of the method (± 0.05 units).

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

The relative density of the test substance was determined under GLP according to OECD 109/EU A3 guidelines, using the pycnometer method.

Duplicate deteminations were performed, density was compared to water at 4°C, and the mean value was retained.

The relative density D204 of the test substance was determined to be 0.93.

Description of key information

The substance is less dense than water.

Key value for chemical safety assessment

Relative density at 20C:
0.93

Additional information

A reliable experimental study, conducted according to a recognized OECD/EU method and under GLP, is available.

Despite minor restrictions due to incomplete test item identification, it is considered as key study, and the result is retained as key data.
