Additional information
Conclusion on classification
According to Article 13 of Regulation (EC) No 1907/2006 "General Requirements for Generation of Information on Intrinsic Properties of substances", information on intrinsic properties of substances may be generated by means other than tests e.g. from information from structurally related substances (grouping or read-across), provided that conditions set out in Annex XI are met. In Annex XI, "General rules for adaptation of this standard testing regime set out in Annexes VII to X”, it is stated that “substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or ‘category’ of substances. This avoids the need to test every substance for every endpoint”.
A read-across approach was applied to this substance and data was compiled from representative source substances to avoid unnecessary animal testing. The target substance will be classified and labelled on this basis.
Environmental fate and pathways
Water solubility
< 0.05 mg/L (20 °C, OECD 105); read-across
Partition coefficient
log Kow > 10 (25 °C, QSAR, EPI Suite v4.11, KOWWIN v1.68)
Degradation
Readily biodegradable: 86.0% in 28 d (OECD 301 F, O2 consumption); read-across
Bioaccumulation
Expert statement: bioaccumulation is assumed to be low.
Aquatic short-term toxicity
Fish
No effects up to the limit of water solubility (OECD 203, EU method C.1, D. rerio/C. carpio, 96 h); read-across
Aquatic invertebrates
No data available
Algae
No effects up to the limit of water solubility (OECD 201, D. subspicatus/S. capricornutum, 72 h); read-across
Aquatic long-term toxicity
Fish
No data available
Aquatic invertebrates
NOEC (21 d) < 7.0 µg/L (nominal, OECD 211, D. magna); read-across
Algae
No effects up to the limit of water solubility (OECD 201, D. subspicatus/S. capricornutum, 72 h); read-across
Conclusion on CLP
Data for aquatic toxicity is available for two trophic levels (fish and aquatic algae for acute toxicity; aquatic invertebrates and algae for chronic toxicity). The substance is readily biodegradable and no short-term effects towards aquatic freshwater organisms were observed up to the limit of the water solubility of the substance. Chronic effects were observed in aquatic invertebrates with a NOEC (21 d) of < 7 µg/L. Based on these results, the substance is classified and labelled as Chronic 1 for long-term environmental hazards according to the consolidated Regulation (EC) No 1272/2008 (dated: 01.03.2018) and further amendments (ATPs).
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).
