Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From September 23,2008 to September 29,2008
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP with certificate.The study is clear and complete in any parts. The substance is well identified, the method is suitable for the substance.
Qualifier:
according to guideline
Guideline:

Key result
Type:
relative density
Density:
ca. 0.89 g/cm³
Temp.:
20 °C

Temperature (°C) Density:(g/mL)
18 0.9986
19 0.9984
20 0.9982
21 0.9980
22 0.9978
23 0.9975
24 0.9973
25 0.9970

The relative density was calculated according to the following equation: D4=ps/pw

ps is the density of test item at room temperature

pw is the density of water at 4°C=0.9999

 determinations weight fatty acids (g) calculated density (g/cm^3
1 46.2342 0.8879
2 46.2255 0.8881
Mean 46.2298 0.8880
Conclusions:
The mean relative density of the test item is D(20°C/4°C)=0.8881 g/cm3
Executive summary:

The density of Fatty Acids C16 -C18 and C18 -unstd., Me esters has been measured according to Council Regulation (EC) No. 440/2008, Method A.3, by

Pycnometer method
