Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018-05-04 - 2018-11-13
- Reliability:

- Key result
- Type:
- density
- Density:
- 0.817 g/cm³
- Temp.:
- 20 °C
- Type:
- relative density
- Density:
- 0.816 other: no unit for rel. density
- Remarks on result:
- other: density of test item at 20 °C to water at 4 °C
- Conclusions:
- Relative density of the test substance at 20 °C to water at 4 °C (0.999975 g/cm3) is 0.8165.
- Executive summary:
The density of the test item was calculated as 0.8165 ± 0.0001 g/cm3 at 20 ± 0.2 °C according to EU method A.3 and OECD guideline 109 and under GLP conditions.
This value represents the mean of two independent determinations ± the standard deviation. Standard deviation shows a very good correlation of the two determinations.
Correspondence of the values is very good. Therefore, the study is considered valid.
Relative density of the test substance at 20 °C to water at 4 °C (0,999975 g/cm3) is 0.8165.
Reference
Pre-test for viscosity
The test item was flowable and it was possible to inject the test item with a one way syringe.
First determination: A density of the test item of 0.8165 g/cm3 was measured at a temperature of 20 °C.
Second determination: A density of the test item of 0.8165 g/cm3 was measured at a temperature of 20 °C.
mean value: 0.8165 g/cm3at a temperature of 20 °C.
Relative density of the test substance at 20 °C to water at 4 °C (0,999975 g/cm3) is 0.8165.
Description of key information
The density of the test item was calculated as 0.8165 ± 0.0001 g/cm3at 20 ± 0.2 °C according to EU method A.3 and OECD guideline 109 and under GLP conditions.
This value represents the mean of two independent determinations ± the standard deviation. Standard deviation shows very good correlation of the two determinations.
Correspondence of the values is very good. Therefore, the study is considered valid.
Relative density of the test substance at 20 °C to water at 4 °C (0,999975 g/cm3) is 0.8165.
The density of hexanal was described also in several handbooks. Described properties are nearly the same: density of hexanal is 0.8335 g/cm3 at 20 °C. Relative density of the substance at 20 °C to water at 4 °C is 0.8335. This is in line with the experimentally derived value.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.817
Additional information
CRC Handbook:
Density of hexanal at 20 °C is 0.8335 g/cm3. Relative density of the substance at 20 °C to water at 4 °C is 0.8335.
Sax Dang. Prop.:
Density of hexanal is 0.808 - 0.812. Relative density of the substance to water at 4 °C is 0.808-0.812. No temperature was stated.
