Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
EU Method A.6 (Water Solubility)
Deviations:
yes
Principles of method if other than guideline:
The water solubility of the test material was investigated in accordance with the standardised guideline EU Method A.6. However it was not possible to determine a value for water solubility due to the nature of the test material. As a result, a determination of the miscibility of the test material with water was carried out by visual assessment using a flask method based on the guideline.
GLP compliance:
yes (incl. QA statement)
Type of method:
flask method

Test material

Constituent 1
Test material form:
other: liquid (not specified)
Details on test material:
Description: dark brown liquid
Storage conditions: room temperature, in the dark

Results and discussion

Details on results:
Miscible with water in all proportions at 20.0 ± 0.5 °C

Overall result: Miscible with water in all proportions at 20.0 ± 0.5 °C

The standard EU Method A.6 procedure was not valid for this test material due to its miscibility with water.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): miscible
The test material has been determined to be miscible with water in all proportions at 20.0 ± 0.5 °C
Executive summary:

The water solubility of the test material was investigated in accordance with the standardised guideline EU Method A.6. However it was not possible to determine a value for water solubility due to the nature of the test material. As a result, a determination of the miscibility of the test material with water was carried out by visual assessment using a flask method based on the guideline.

Solutions of the test material in double-distilled water at concentrations of 5.01, 50.0 and 95.0 % w/w were prepared and equilibrated and assessed visually.

The test material has been determined to be miscible with water in all proportions at 20.0 ± 0.5 °C.
