Link to relevant study record(s)
- Endpoint:
- density, other
- Remarks:
- density of liquids and solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:

- Justification for type of information:
- A discussion and report on the read across strategy is given as an attachment in IUCLID Section 13.
- Reason / purpose for cross-reference:
- read-across: supporting information
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- pycnometer method
- Key result
- Type:
- density
- Density:
- ca. 1 160 kg/m³
- Temp.:
- 21.4 °C
- Conclusions:
- The density of the test item has been determined to be 1160 kg/m3 at 21.4 ± 0.5°C
- Executive summary:
The determination of the density was carried out using a gas comparison pycnometer, designed to be compatible with EU Method A.3, and OECD Guideline 109. Triplicate pressure readings were taken after pressurising the reference cell of known volume and then switching to the sample cell.
This is a GLP-compliant, guideline study, therefore the result is reliable without restrictions.
Reference
Although the test item is a liquid at room temperature, it was extremely viscous and therefore it was not possible to determine density using glass pycnometers which is the method of choice for liquids. Therefore the density of the test item was determined using a gas comparison pycnometer instead.
Description of key information
There is no data available for Resin acids and rosin acids, reaction products with formaldehyde, sodium salts. However, data available from a structural analogue Resin acids and rosin acids, reaction products with formaldehyde, potassium salts is used as read across.
The density for members of the category Rosin, hydrogenated rosin and their salts ranges from 1006 kg/m3 to 1160 kg/m3.
The density of Resin acids and rosin acids, reaction products with formaldehyde, potassium salts is 1160 kg/m3 at 21.4°C.
Key value for chemical safety assessment
Additional information
There is no data available for Resin acids and rosin acids, reaction products with formaldehyde, sodium salts. However, data available from a structural analogue Resin acids and rosin acids, reaction products with formaldehyde, potassium salts is used as read across.
A GLP-compliant study, conducted according to OECD Guideline 109 and EU Method A.3 (gas comparison pycnometer), was provided for Resin acids and Rosin acids, reaction products with formaldehyde, potassium salt (Harlan Laboratories Ltd., 2012a)
