Conclusion on classification

In order to determine the classification for hazardous properties related to the aquatic environment, the criteria of the Regulation (EC) No 1272/2008 (CLP) version 2016 in Annex I were accurately followed.

Short-term (acute) aquatic hazard:

For classification, acute toxicity data are available for fish, aquatic invertebrates (Daphnia) and algae:

Fish: LC50 (96h) > 0.643 mg/L

Daphnia: EC0 (48h) = 2.8 mg/L

Algae: EC50 (72h, growth rate) = 0.386 mg/L

The criteria in Table 4.1.0 (a) of Annex I of the CLP Regulation were applied.

The lowest LC50 or EC50 value was observed for Algae, which is hence the most sensitive species. According to Table 4.1.0 (a) the substance should be classified for acute aquatic hazard, as the lowest LC50 value, EC50 (72h, growth rate) for Algae is 0.386 mg/L, which is below the cut-off for classification of 1 mg/L. The substance should be classified as Acute (short-term) aquatic toxic 1.

Long-term (chronic) aquatic hazard:

For chronic classification, there are only chronic data available for one trophic level, algae. As described in Figure 4.1.1 in the CLP regulation (EC No 1272/2008, version 2016), the most stringent outcome of classification according to Table 4.1.0 (b) (i) or (ii) and (iii) should be used.

Table 4.1.0 (b) (ii):

The substance is readily biodegradable, hence Table 4.1.0 (b) (ii) applies.

The EC10 (72h, growth rate) for algae was 0.122 mg/L, which is in the range of cut-off values for classification as chronic category 3: > 0.1 and ≤ 1 mg/L. Therefore, the substance should be classified for chronic aquatic toxicity, category 3.

Table 4.1.0 (b) (iii):

Classification based on available acute data available for 3 trophic levels and environmental fate data:

Fish: LC50 (96h) > 0.643 mg/L

Daphnia: EC0 (48h) = 2.8 mg/L

Log Kow = 4.18

The substance is readily biodegradable.

Based on the criteria Table 4.1.0 (b) (iii), the substance should be classified as chronic aquatic toxic, category 2 since the lowest EC50 value for daphnia is > 1 and ≤ 10 mg/L and the low Kow value is ≥ 4.

Most stringent chronic classification:

The conclusion of both assessment is that the substance should be classified for chronic aquatic hazard, category 2.
