Overall concentration: <1.0 x 10-4 g/l at 20.0 ± 0.5ºC
Discussion:
The relatively large, unknown peaks in the sample chromatograms at approximately 1.5, 3.1 and 4.2 minutes were not seen during method validation. Thus, these peaks have been considered to be due to water-soluble, UV-absorbing impurities in the test material.
Validation
The linearity of the detector response with respect to concentration was assessed over the nominal concentration range of 0 to 250 mg/l. This was satisfactory with a correlation coefficient of 1.000 being obtained.
Recovery of analysis of the sample procedure was assessed and proved adequate for the test.
Recovery data is shown in the following table:
Nominal Concentration (g/l) |
Recovery(%) |
Mean Recovery (%) |

76.3 to 89.8 |
81.5 |
1.0 x 10-3 |
85.4 to 93.6 |
88.5 |
No test material was detected in any of the sample solutions; therefore, a limit value for these solutions was taken as 1.0 x 10-4g/l, i.e. the lowest nominal concentration used during method validation.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
The water solubility of the test material has been determined to be less than 1.0 x 10-4 g/l of solution at 20.0 ± 0.5°C. - Executive summary:
- Water Solubility: Less than 1.0 x 10-4g/l of solution at 20.0 ± 0.5°C, using the flask method, Method A6 Water Solubility of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 105 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
