EC number: 289-621-8 | CAS number: 89957-99-3 Extractives and their physically modified derivatives such as tinctures, concretes, absolutes, essential oils, oleoresins, terpenes, terpene-free fractions, distillates, residues, etc., obtained from Boswellia papyrifera, Burseraceae.
Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- November 15, 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- The study was conducted according to an internationally recognised method, and under GLP. The test substance is adequately characterised. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Version / remarks:
- 2012
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- GLP compliance programme (inspected on 20-21 June 2017 / signed on 4 September 2017)
- Type of method:
- oscillating densitimeter
- Key result
- Type:
- density
- Density:
- 0.893 g/cm³
- Temp.:
- 20 °C
- Key result
- Type:
- relative density
- Density:
- 0.89 other: unitless
- Remarks on result:
- other: The relative density of the test item at 20 °C (compared to water at 4 °C)
- Conclusions:
- The test substance is less dense than water.
The mean relative density of the test item was D20/4 = 0.89 ± 0,01 - Executive summary:
The density of the test substance was measured according to OECD 109 / EU A3 guideline, using oscillating density meter. After calibration, two determinations were performed and the mean value was retained.

Final results
The relative density of the test item at 20 °C (compared to water at 4 °C) according to the European Commission Regulation (EC) No. 440/2008 and in the OECD 109 was determined to be: D420= 0.89
Description of key information
The test substance is less dense than water.
The mean relative density of the test item was D20/4 = 0.89 ± 0,01
Key value for chemical safety assessment
- Relative density at 20C:
- 0.89
Additional information
A fully reliable experimental study, conducted according to OECD 109 /EU A3 guideline, using oscillating density meter, is available. It is considered as a key study, and the result is retained as key data.
