Results and discussion
Water solubility
- Water solubility:
- 1.31 g/L
- Temp.:
- 21 °C
- pH:
- 11.4
Any other information on results incl. tables
The water solubility estimated in the preliminary test was 1.46 g/l.
The regression coefficients of the linearity determination from the spectrophotometric method are the following:
-slope: 5.02 x 10^-2
-intercept: 3.50 x 10^-2
-correlation coefficient: 0.9995, n=4
The analytical method used for the determination of the water solubility was determined to be linear between 10.2 mg/l and 28.0 mg/l.

*Duplicate samples
The maximum deviation between the 48 and 72 hours measurements was determined to be <15%. The test was considered valid according to the OECD and EEC guidelines.
The 24, 48 and 72 hours measurements were in agreement, therefore the water solubility of ADDOTTO GM 102E/BAF as the mean value of all measurements.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): soluble (1000-10000 mg/L)
The water solubility of the substance at 20.8-21.0°C was determined to be 1.31 g/l, using the flask method.
