Additional information
Acute toxicity tests are available for the three throphic levels algae, invertebrates and fish. An acute toxicity test with Alburnus alburnus in brackish water showed a LC50 of >10000 mg/L. No toxicity has been observed in the tests on daphnia and algae. The toxicity of the test substance on Daphnia magna has been tested according to OECD TG202 and the coreesponding EC50 (48 h) is > 220 mg/L. Further publications revealed also high LC50 for Nitocra spinipes in brackish water. In the toxicity test with algae according to OECD TG 201, an ErC50 (72 h) of > 316 mg/L has been determined. The NOErC has been determined to be ≥ 316 mg/L and after 72 h exposure. In conclusion, the test substance 1,2,6 -hexanetriol is considered to be not toxic on aquatic organisms.
Conclusion on classification
The effect levels of the test substance on aquatic organisms are above the threshold level of 100 mg/L and the test substance has been shown to be readily biodegradable. Therefore, the test substance does not need to be classified according to CLP regulation or UN-GHS regulation.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
