Appearance / physical state / colour
Administrative data
- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see "Remarks"
- Remarks:
- The appearance of the test item is described in a reliable study report on the physical-chemical properties of the substance. Since no guideline was followed and no details on the methods are given, the description is considered as reliable with restrictions.
Cross-reference
- Reason / purpose for cross-reference:
- reference to same study
Reference
- Endpoint:
- density, other
- Remarks:
- density in g/cm³
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The test item will become a paste at ambient temperature, so the density cannot directly be determined at ambient temperature using the internal standard procedures (by means of Stabinger viscometer), or by extrapolating the densities obtained at higher temperatures where this raw material is a fluid. Therefore, an alternative method was needed to determine this density.
A procedure similar to the “pour and tap” method was used. The volume of a known weight of the test substance was measured by means of a graduated Babcock bottle. Before testing, the bottle was calibrated with demineralized water at known temperature in order to precisely determine the volume of the bottle (on the basis of water’s density and weight). The whole calibration and measurement procedure is reported in section “Any other information on materials and methods incl. tables” - GLP compliance:
- no
- Type of method:
- other: similar to pour and tap
- Key result
- Type:
- density
- Density:
- >= 0.926 - <= 0.928 other: relative density is dimensionless.
- Temp.:
- 20 °C
Calibration of the Babcock bottle (< 0 mL)
Weight of bottle plus water up to 0 mL: 157.0072 g
Weight of empty bottle: 57.3462 g
Weight of water: 157.0072 - 57.3462 = 99.6610 g
Measured temperature: 22 °C
Density of water at 22 °C = 0.9977 g/cm³
Volume of the Babcock bottle (up to < 0 mL): 99.6610 g / 0.9977 g/cm³ = 99.89 mL
Calibration Babcock bottle (0 - 10 mL)
Weight of bottle plus water up to 8.1 mL: 165.0803 g
Weight of bottle plus water up to 0 mL: 157.0072 g
Weight of water (0 to 8.1 mL): 8.0703 g
Measured temperature: 22 °C
Density of water at 22 °C = 0.9977 g/cm³
Calculated volume 0 (nominal 8.1 mL): 8.0703 g / 0.9977 g/cm3 = 8.09 mL
Conclusion: 1 mL on scale ≈ 1 mL
Determination of the test item density
Measured volume of test item in the Babcock bottle:
Volume at 55 °C: 6.95 mL
Volume at 20 °C: 3.50 - 3.70 mL
Weight of bottle plus test item: 153.2447 g
Weight of empty bottle: 57.3462 g
Weight of test item: 95.8985 g
Total volume of test item (at 20 °C):
- Min volume = 3.5 mL + 99.89 mL = 103.39 mL
- Max volume = 3.7 mL + 99.89 mL = 103.59 mL
Max density (at 20 °C) = 95.8985 g / 103.39 mL = 0.928 g/cm³
Min density (at 20 °C) = 95.8985 g / 103.59 mL = 0.926 g/cm³
Check of the Babcock bottle by means of Stabinger viscometer
Density at 40 °C of the test item (Stabinger report): 0.9053 g/cm³
Density at 100 °C of the test item (Stabinger report): 0.8677 g/cm³
Density at 55 °C (interpolation of Stabinger curve): 0.8959 g/cm³
Conclusion: Stabinger uses linear relation between temperature and density.
Weight of bottle plus test item: 153.2447 g
Weight of empty bottle 57.3462 g
Weight of test item: 95.8985 g
Volume (< 0 mL): 99.89 mL
Volume (0 - 10 mL scale): 6.95 mL (at 55 °C)
Total volume: 106.84 mL
Density at 55 °C = 95.8985 g / 106.84 mL = 0.8976 g/cm³
Conclusion: Density interpolation from Stabinger (0.896 g/cm³) ≈ Density alternative method (0.898 g/cm³)
Calculation of the relative density
The relative density of the substance at 20 °C compared to water at 4 °C was not reported but can be calculated according to “EU Test guideline A.3 for relative density Regulation (EC) No 440/2008” and “ECHA Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.7a: Endpoint specific guidance”.
The density of water at 4 °C (at which temperature, water has its maximum density) is 999.975 kg/m³ (0.999975 g/cm³).
The relative density of the test substance is obtained as follows:
D420 = density of test item at 20 °C / density of water at 4 °C
Max relative density = 0.928 g/cm³ / 0.999975 g/cm³ = 0.928
Min relative density = 0.926 g/cm³ / 0.999975 g/cm³ = 0.926
