Additional information

Conclusion on classification

It is noted that that no adverse effects up to the limit of solubility have been observed in aquatic study, and therefore no true PNEC can be derived.

The calculated PNEC values are based on solubility which is higher than the actual water solubility value of the substance at least by two orders of magnitude.

No toxicity to aquatic organisms is expected, although the calculated PNEC values are very small.
