Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
Doubt was raised in 1995 in the original notification of the substance about the determined water solubility and comparison was made in the risk assessment with calculated water solubility (116,7 mg/l). The registrant made a new calculation in Epi Suite program KowWin 1.01 of Water solubility and this resulted in a value of 0.002632 mg/l at 25°C. This is even lower than the experimental determined water solubility. Therefore the conclusion is that this experimental value of water solubility is accurate.
