Reference
Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2010-01-11 to 2010-01-20
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 test substance composition is adequately characterised with its purity. Therefore full validation applies.
Qualifier:
according to guideline
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)

Key result
Type:
relative density
Density:
0.933 other: relative density is dimensionless
Temp.:
20 °C

Determination 1: 0.933 at 20°C

Determination 2: 0.933 at 20°C

Determination 3: 0.933 at 20°C

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

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

Three determinations were performed; results were consistent, so the average value was retained.

The relative density of the test substance is 0.933 at 20°C.

Description of key information

The substance is less dense than water.

Key value for chemical safety assessment

Relative density at 20C:
0.933

Additional information

A fully reliable 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.
