Justification:

Conclusion on Persistance: potentially vP (and P)

The ready biodegradability of the test substance was investigated according to the OECD 301 D. The test substance undergoes 11.8 % biodegradation after 28 days. Therefore, test substance is not regarded as readily biodegradable according to OECD criteria, but poorly biodegradable in this test. Based on the available data, the substance is considered to be potentially P or vP.

Conclusion on Bioaccumulation: Not B and not vB

The log Pow of the test item is estimated to be < -0.4 (see IUCLID section 4.7) based on the solubility in n-octanol and water. This result is far below the threshold value for bioaccumulative potential of log Pow > 4.5 as cited in the ECHA Guidance on Information Requirements and Chemical Safety Assessment, Part C: PBT/vPvB assessment (Version 3.0, June 2017). Thus, the substance is not considered to be very bioaccumulative (vB) or bioaccumulative (B).

Conclusion on Toxicity: Not T

In a 72-h growth inhibition study with algae (Raphidocelis subcapitata) the test item had not any significant toxic effect on the test system at the tested limit concentration of 100 mg/L (nominal). The 72-h NOEC was determined to be 0.1 mg/L (Limit of detection, corresponding to a nominal concentration of 100 mg/L). Thus, the NOEC for freshwater organisms (long-term toxicity) is > 0.01 mg/L and the criterion for T properties is not fulfilled. Further, the substance does not meet the criteria for classification as carcinogenic (category 1A or 1B), germ cell mutagenic (category 1A or 1B), toxic for reproduction (category 1A, 1B, or 2) or specific target organ toxicity after repeated exposure (STOT RE category 1 or 2) according to Regulation EC No 1272/2008. Thus, the substance is considered as not T.

Overall conclusion on PBT and vPvB

Based on the available information, the substance is not PBT / vPvB according to Regulation (EC) 1907/2006.
