Additional information

Conclusion on classification

For classification purposes ecotoxicity, biodegradability and bioconcentration have to be considered.

Ecotoxicity:

Aquatic acute toxicity data of the registered substance are available for the three trophic levels and are summarised here below :

- 96h-LC50 for fish = 18.57 mg/L (time-weighed mean measured concentrations

- 48h-EC50 for invertebrates = 30 mg/L (nominal concentrations as measured concentrations in the range of 80 -120%)

- 72h-ErC50 for algae = 48 mg/L (geometric mean measured concentrations)

- 72h-NOErC for algae = 8.7 mg/L (geometric mean measured concentrations)

Biodegradability:

The substance is rapidly biodegradable in the environment as demonstrated with an OECD TG 301 C (Modified MITI Test (I). The biodegradation percentage was 96% after 14 days.

Bioconcentration:

Based on the LogKow = 2.86, the substance has a low potential for bioaccumulation.

Conclusion classification according to CLP regulation 1272/2008:

Based on the results of the acute toxicity data (lowest LC50 = 18.57 mg/L), the substance does not need acute classification.

Based on the results of the acute toxicity data (lowest LC50 = 18.57 mg/L) and the chronic data for algae (NOEC = 8.7 mg/L), the substance does not need chronic classification.
