Conclusion on classification

Classification related key information

- Biodegradation: Readily biodegradable according to OECD criteria (79% after 28d, OECD 310)

- Bioaccumulation potential: Log Pow: 5.64 to 5.77 (at 23.4 °C) for the two isomers of the substance (EU Method A.8)


- Aquatic acute toxicity:

Fish: no data available

Aquatic invertebrates: EC50 (48 h) Daphnia magna = 127 µg/L (geometric mean measured concentration, OECD 202)

Algae: ErC50 (72 h) Pseudokirchneriella subcapitata >0.449 mg/L (based on time weighted average, OECD 201)

- Aquatic chronic toxicity:

Fish: no data available

Algae: ErC10 (72 h) Pseudokirchneriella subcapitata = 0.354 mg/L (based on time weighted average, OECD 201)

Aquatic invertebrates: no data available

Classification justification according to CLP

Based on the data above, the substance is considered to be rapidly degradable in the environment but has a potential for bioaccumulation (log Pow > 5). Based on the acute data from aquatic invertebrates (EC50 (48 h) = 127 µg/L) the substance has to be classified as “Aquatic Acute 1” (H400) and "Aquatic Chronic 1" (H410) according to the Regulation (EC) No 1272/2008 (CLP consolidated version dated 01.01.2017) and the Regulation (EU) No 1297/2014 (7th ATP).

M-factor (acute toxicity): 1
