Additional information

The approach given on the ECHA Guidance R.10 could not be followed, as the test substance was insoluble in water, and the test results consistently demonstrated that no acute toxic effects was observed at the highest achievable test concentrations, which varied from 0.05 to 0.1 mg/L.

The test concentration in the STP test was most probably a nominal concentration (details were not available).

Conclusion on classification

The lowest determined NOEC on algae >= 0.08 mg/L, the solubility limit of the substance, indicate that the substance possesses no acute toxicity at levels up to water solubility.
