Materials and methods

Test guideline
Qualifier:
no guideline followed
Principles of method if other than guideline:
The substance was stirred with double distilled water at a nominal concentration of 1.05 mg/L at 19.9 +/- 0.3°C for 96 hours (4 days). After stirring, the water solubility was visually interpreted.
GLP compliance:
yes
Type of method:
other: visual determination, as low as technically possible

Name:
Unnamed
Type:
Constituent
Details on test material:
- Name of test material (as cited in study report): L 131
- Appearance: Faint light-green powder

Results and discussion

Water solubility
Water solubility:
< 1 mg/L
Temp.:
20 °C
pH:
7.2
Details on results:
- After the stirring period, undissolved test substance was observed in the test sample. From this, it was concluded that the water solubility at 20°C was < 1 mg/L
- The pH of the aqueous sample was 7.2

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): other: considered to be insoluble
In a GLP-compliant study the water solubility of the substance at 20°C has visually been determined as < 1 mg/L. Based on this, the substance is considered to be insoluble in water.
