Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

AquaticShort-term L(E)C50 results are available for each of the three trophic levels.

Fish:Short-term toxicity to Cyprinus carpiowas investigated in an OECD TG 203 limit test (Bouwman, 2004) at a nominal test concentration of 100mg/L. No mortality or other adverse effects could be observed at the end of the exposure period and therefore, a precise LC50 value could not be calculated and it is considered to be >0.015 mg/L (mean measured concentration).

Invertebrates:An OECD TG 202 acute toxicity test toDaphnia magna(Bouwman, 2004) was performed at a nominal test concentration of 100mg/L. After 48 hours, no immobilisation or other adverse effects were reported, and therefore a precise EC50 could not be determined and it is considered to be >0.019 mg/L (mean measured concentration).

Algae:An OECD TG 201 algal growth inhibition test (Bouwman, 2004) was performed at a nominal test concentration of 100mg/L. No significant effects regarding biomass or growth rate were observed after 72 hours exposure to the test substance. Therefore, a precise EC50 value could not be determined and it is considered to be > 0.01 mg/L (average exposure concentration). This is considered as the most sensitive species based on the lowest measured exposure concentration over all three trophic levels.

Toxicity to microorganisms:The toxicity to microorganisms was tested on sewage micro-organisms by measuring the respiration rate under defined conditions in accordance to OECD Guideline 209. Under the conditions of the test, no inhibition of respiration was observed in either replicate with an EC50 >100 mg/L. The test substance is therefore considered to be not toxic to waste water bacteria at concentrations exceeding the limit of solubility.
