Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

Conclusion on classification

The results from the aquatic toxicity studies are as follows:

Short-term toxicity to fish: Key study: OECD guideline 203 and EU guideline C.1. The 96-Hour LC50 based on nominal test concentrations was 18 mg ai/l with 95% confidence limits of 14 - 24 mg ai/l. The No Observed Effect Concentration was 14 mg ai/l.

Short-term toxicity to aquatic invertebrates: Key study: OECD guideline 202 and EU guideline C.2. The acute toxicity of the test material to the freshwater invertebrate Daphnia magna has been investigated and gave a 48-hour EC50 value of 16 mg ai/l with 95% confidence limits of 12-19 mg ai/l. The No Observed Effect Concentration at 48 hours was 4.3 mg ai/l.

Toxicity to aquatic algae and cyanobacteria: Key study: OECD Guideline 201 and EU Guideline C.3. GLP study. The 72 -h EC50 based on growth rate was 3.4 mg ai/l with 95% confidence limits of 2.7 -4.3 mg ai/l. The No Observed Effect Concentration was 1.1 mg ai/l.

Based on the results from the aquatic toxicity (lowest value between 1 and 10 mg/l) and since the substance is readily biodegradable and has a log Pow below 4, the substance is not classified according to Directive 67/548/EEC and CLP Regulation 1272/2008.
