PBT status:
the substance is not PBT / vPvB
Justification:

Conclusion on Persistance: potentially vP (and P)

The ready biodegradability of the test substance was investigated according to the OECD 301 D. Maximum degradation of the substance after 28 days was 17.8 %. 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 potential vP (and P).

Conclusion on Bioaccumulation: Not B and not vB

The log Pow of the test item was measured according to an internal method to be < -0.3 (see IUCLID section 4.7). This result is 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

The criterion for toxicity is not fulfilled, since the NOEC for aquatic organisms is >= 0.01 mg/L. The 7 d NOEC (growth rate Lemna gibba) was determined to be 0.023 mg/L (geometric mean measured, corresponding to a nominal loading rate of 100 mg/L); and the substance is not classified as carcinogenic, mutagenic or toxic for reproduction according to directive 67/548, or carcinogenic, germ cell mutagenic or toxic for reproduction according to Regulation EC No 1272/2008; and there is no evidence of chronic toxicity according to Directive 67/548/EEC, or specific target organ toxicity after repeated exposure according to Regulation 1272/2008.

Overall conclusion on PBT and vPvB

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