Conclusion on classification

No relevant toxic effect was shown in aquatic tests. The REACH substance has a high molecular weight (98.98% > 1000 Dalton). Under environmental conditions the substance will be oxidized to very big polymeric structures with a very high molecular weight. The bioavailability of the substance is negligible (low potential to cross biological membranes).

This means that according to the criteria used by the Dangerous Substance Directive (DSD) 67/648/EEC and the 2nd ATP of Classification Labelling and Packaging Regulation (CLP) 2011/286/EC Leuso sulfur Brown 37 has not to be classified as dangerous to the environment neither for short-term nor for long-term effects.
