Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusion on classification
Classification related key information
Biodegradation in water: Not readily biodegradable: -1% biodegradation at 28 days (OECD 301 D); inherently biodegradable: 86.9% biodegradation at 28 days based on BOD, and >99.9% biodegradation at 28 days based on residue analysis (OECD 302 C)
Log Kow: - 2.5 (OECD 107)
Acute toxicity:
- to Fish: LC50 (96 h) > 100 mg/L for Oncorhynchus mykiss, and Gobiocypris rarus (nominal, OECD 203)
- to aquatic invertebrates: EC50 (48h) > 100 mg/L for Daphnia magna (nominal, OECD 202)
- to Algae: ECr50 (72h) > 121.6 mg/L for Pseudokirchneriella subcapitata (nominal, OECD 201)
Chronic toxicity:
- to Fish: NOEC (28 d) ≥ 100 mg/L for Gobiocypris rarus (nominal, OECD 215)
- to aquatic invertebrates: NOEC (21d) ≥ 10 mg/L for Daphnia magna (nominal, OECD 211)
- to Algae: NOErC (72h) ≥ 121.6 mg/L for Pseudokirchneriella subcapitata (nominal, OECD 201)
Classification justification according to CLP
Based on the data above, the substance is considered not rapidly biodegradable but inherently biodegradable. No acute toxicity effects were detected up to 100 mg/L of Fosetyl-Sodium. Valid chronic toxicity data are available for fish, algae and daphnia – the lowest NOEC is 10 mg/L for Daphnia magna. Therefore, the substance does not need to be classified and labelled as environmental hazard according to the consolidated version of Regulation (EC) No 1272/2008 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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
