Conclusion on classification
Referring to the effect concentrations of Macrolex Orange R it has to be classified according to the following reasons:
- No effects were determined in acute tests (algae and fish) and a preliminary acute test preceding the long-term toxicity study with daphnids.
- The most sensitive chronic toxicity for Macrolex Orange R is to invertebrates. As a NOEC of 0.255 mg/L has been determined for daphnids after 21 d.
- Macrolex Orange R is not readily biodegradable.
Depending on this the substance has to be classified as Category Chronic 2, H411, according to Regulation (EC) No. 1272/2008 (CLP).
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).
