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) > 1.38 mg/L

Daphnia: EC0 (48h) = 8.7 mg/L

Algae: EC50 (72h, growth rate) = 5.57 mg/L

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

According to Table 4.1.0 (a) the substance should not be classified for acute aquatic hazard, as allt LC50/EC50 values are above the cut-off for classification of 1 mg/L. The substance should not be classifed as Acute toxic.

 

Long-term (chronic) aquatic hazard:

For chronic classification, there is 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 3.53 mg/L, which is not in the range of cut-off values for classification, hence, the substance should not be classified for chronic aquatic hazard according to this table.

Table 4.1.0 (b) (iii):

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

Fish: LC50 (96h) = 1.38 mg/L

Daphnia: EC0 (48h) = 8.7 mg/L

Log Kow = 4.47

The substance is readily biodegradable.

Based on the criteria Table 4.1.0 (b) (iii), the substance should be classified as category chronic 2 since the lowest EC value iis found in the range of >1 to <10 mg/L, moreover, the log Kow is > 4.

Most stringent classification:

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