Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- 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)
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- pycnometer method
- Type:
- relative density
- Remarks on result:
- not determinable because of methodological limitations
- Conclusions:
- Solvent Violet 13 could not be separated from the solvent because either the test item floated on top of the solvent and / or the test item clumped together. Therefore no relative density could be determined by the pycnometer method.
- Executive summary:
A study was conducted to assess the relative density of Solvent Violet 13 according to OECD guideline 109 'Density of Liquids and Solids' which is in all essential parts equal to EC A.3 'Relative density'. The solid sample was accurately weighed into a 20 mL pycnometer and by displacement of the solvent (demineralized water mixed with Tween 20 to lower the surface tension), its equivalent volume was determined.
Solvent Violet 13 could not be separated from the solvent cause either the test item floated on top of the solvent and / or the test item clumped together.
Therefore no relative density could be determined by the pycnometer method.
Reference
The test item could not be separated from the solvent cause either the test item floated on top of the solvent and / or the test item clumped together. Therefore no relative density could be determined by the pycnometer method.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
