Type of information:
experimental study
Adequacy of study:
key study
Study period:
From July 29 to September 6, 2005
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
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 considered to be adequately characterised with its purity. Therefore full validation applies.

Conclusions:
The test substance is slightly more dense than water.
Executive summary:

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

Two tests were performed concurrently, and the relative density was calculated vs water at 4°C.

The relative density (D20/4) of test substance has been determined to be 1.07 at 20 °C.

Description of key information

The substance is slightly more dense than water.

Key value for chemical safety assessment

Relative density at 20C:
1.07

Additional information

A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Therefore, it is considered as a key study. The result is retained as key data.
