Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- The study was initiated on 13 April 2017 and completed on the date the final report was signed by the Study Director.
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:
- Due to the viscous nature of the test item the relative density was determined by a gas comparison pycnometer method conforming to OECD Guideline 109.
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: Gas comparison pycnometer method conforming to OECD Guideline 109.
- Specific details on test material used for the study:
- Sponsor batch: E01133-065
Purity: 100 %
Arrival date: 6 March 2017
Re-test date: 31 July 2019
Storage conditions: Refrigerated (2 to 8°C) under nitrogen. The test substance was supplied in a translucent HDPE container and has been stored in this container. The test substance was stored in a fridge, in the dark when not in use. - Key result
- Type:
- relative density
- Density:
- 1.079 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The density of the test item was found to be 1.0789 g/cm3 (1078.9 kg/m3).
- Executive summary:
In a study, according to OECD 109, the density of neodecanoic acid, iron salt has been characterised. The density of the test item was found to be 1.0789 g/cm3 (1078.9 kg/m3); the mean of 1.0790, 1.0792, 1.0788, 1.0782 and 1.0792 g/cm3 with a standard deviation of 0.0004 g/cm3. For the AccuPyc 1330TC instrument used, the accuracy is to within 0.03% of the reading plus 0.03% of the nominal full-scale cell chamber volume (10 cm3).
Therefore, the relative density (D_4^20) is 1.0789.

- Key result
- Type:
- density
- Density:
- 0.91 g/cm³
- Temp.:
- 20 °C

Description of key information
In a study, according to OECD 109, the density of neodecanoic acid, iron salt has been characterised. The density of the test item was found to be 1.0789 g/cm3 (1078.9 kg/m3); the mean of 1.0790, 1.0792, 1.0788, 1.0782 and 1.0792 g/cm3 with a standard deviation of 0.0004 g/cm3. Therefore, the relative density (D_4^20) is 1.0789.
As a supporting approach, read-across has been made to neodecanoic acid (EC No. 248 -093 -9; CAS No. 26896 -20 -8). The determined value is 0.911 g/cm³ at 20°C.

Additional information
The density of the test item was found to be 1.0789 g/cm3 (1078.9 kg/m3); the mean of 1.0790, 1.0792, 1.0788, 1.0782 and 1.0792 g/cm3 with a standard deviation of 0.0004 g/cm3. For the AccuPyc 1330TC instrument used, the accuracy is to within 0.03% of the reading plus 0.03% of the nominal full-scale cell chamber volume (10 cm3).
