Additional information
Most of the chemical is expected to be disposed of to landfill along with printed paper or released to recycling wastewaters when used paper is recycled. Given that it is insoluble in water, the chemical is expected to partition to sewage sludge rather than the supernatant water following paper recycling processes. During waste water treatment processes in STPs, the chemical is therefore expected to be efficiently removed from influent due to its low water solubility and soil adsorption values. Minimal chemical is expected to be released to surface waters.
The chemical is not readily biodegradable, but is inherently biodegradable, and hence would be removed from surface waters, soil, landfill, sediment or sludge via degradation by biotic and abiotic processes to form water, and oxides of carbon. The chemical is not expected to bioaccumulate due to its n-octanol/water partition coefficient and derived bioaccumulation values. The chemical is unlikely to be mobile based on its water solubility and adsorption coefficients in landfill and soil.
Derivation of PEC / PNEC is not considered to be relevant, as the substance demonstrates no toxicity at the limit of solubility to aquatic organisms in both acute and chronic studies. Given the diffuse nature of the potential for exposure, it is unlikely that the substance can ever be present at levels higher than its water solubility in a specific region; hence investigation of PEC/PNEC values for the aqueous environment is essentially redundant. Furthermore, the substance is not toxic to terrestrial organisms on the basis of the earthworm toxicity.
Based on the available data used in support of the registration, the substance is proposed to be non-toxic, non-bioaccumulative and inherently biodegradable. In the event of significant environmental exposure, the substance is proposed to partition mainly to soil / sediment compartments, where it is predicted not to be toxic on the basis of available data. The substance is inherently readily biodegradable hence this route of degradation will result in eventual removal of the substance from the environmental compartments. No risk is proposed.
Conclusion on classification
In accordance with Regulation 1272/2008, the substance does not meet the criteria for classification.
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).
