Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

No acute environmental toxicity is recorded at levels up to 100 mg/L which is in excess of the solubility limit (1 mg/L). Long term studies for algae and Daphnia are available, both showing NOEL > 100 mg/L. As no fixed E(L)C50 value can be set, a PNEC aqua cannot be derived.

No ecotoxicological data for soil- and sediment-dwelling organisms are available. In absence of a PNEC aqua and since the log Kow could not be determined exactly, the PNEC sediment and soil cannot be derived by equilibrium partition method calculation.

For soil a long-term toxicity study (Annex IX) is proposed.

Conclusion on classification

The lowest short-term toxicity value between Daphnia, algae and fish are the WAF results with Daphnia and algae, both resulting in an EL50 > 100 mg/L and NOEL > 100 mg/L.Thus according to Directive 67/548/EEC and according to Regulation 1272/2008/EC (CLP), SLO does not need to be classified for acute toxicity to aquatic organisms. SLO is a poorly soluble substance (water solubility <1 mg/L) for which no acute toxicity is found at levels up to the water solubility. SLO is not readily biodegradable and has a log Kow >4. A 21d reproduction toxicity test with Daphnia and SLO resulted in a NOELR of 100 mg/L, indicating that long-term effects are not to be expected. Based on these results SLO is not classified for environmental hazards.
