Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
June 22th 2021
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
A fully reliable non GLP study was conducted according to an internationally recognised method. No deviation affected the quality of the study. The substance is adequately identified. Therefore full validation applies.

Relative density mean value = 0.917 at 20°C.

Conclusions:
The relative densitity (D20/20) was determined to be 0.917 (average value) at 20°C.
Executive summary:

The relative density (D20/20) of the test item at 20°C was measured according to the recognized OECD 109 / EU Method A.3 using the oscillating densimeter.


The measurements were performed in duplicate at 20°C and the results were automatically corrected with regard to the viscosity of the test item.


The relative densitity (D20/20) was determined to be 0.917 (average value) at 20°C.

Description of key information

The relative densitity (D20/20) was determined to be 0.917 (average value) at 20°C.

Key value for chemical safety assessment

Relative density at 20C:
0.917

Additional information

A fully reliable experimental study, conducted according to the recognized OECD 109 / EU A.3 methods is available.
It is considered as a key study, and the result is retained as key data.
