Additional information
Conclusion on classification
According to reliable short term studies conducted on fish, invertebrates and algae the 1,6 -Divinylperfluorohexane is not acutely toxic to aquatic organisms.
However 1,6 -Divinylperfluorohexane is not ready biodegradable, it has a partition coefficient Log Kow > 4 and it is poorly soluble in water as the solubility in pure water was found just slightly above 1 mg/L and the maximum concentrations achieved in ecotoxicological testing were all below 1 mg/L.
Basing on these parameters it fulfills the criteria to be classified in Aquatic Chronic Category 4 according to CLP and GHS criteria.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
