Description of key information
All main components of the registered substance are included in the composition of a similar substance, which was tested in accordance to the OECD Test Guideline 105 and to GLP principles. The water solubility of the registered substance was below the LOQ of <0.0055 µg/L at 20°C.
Key value for chemical safety assessment
- Water solubility:
- 0.005 µg/L
- at the temperature of:
- 20 °C
Additional information
The key study identified was not performed with the test substance but with a chemically similar test substance including the test substance as a fraction of its main components. Among these components, the test substance was identified as the fraction for which the water solubility was determined below the LOQ of <0.0055 µg/L at 20°C.
The supporting study conducted on the test substance gave only an estimation based on visible saturation of 1 mg in 5 L of distilled water, as the test substance is highly insoluble.
Moreover, the WSKOWIN predictions from EPISUITE v4.11 (US EPA) software confirm these results . All the three constituants of the registered UVCB are insoluble and their predicted solubilities are relevant when regarding the key water solubility value < 0.0055 µg/L.
