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).
According to the criteria used by the Regulation (EC) No 1272/2008 (CLP) as amended for seventeenth time in Regulation (EU) No 2021/849, Leuco Sulphur Brown 37 has not to be classified as dangerous to the environment neither for short-term nor for long-term effects.


Therefore, no hazard was identified and no PNEC derivation performed.
