Classification & Labelling & PBT assessment

PBT assessment

Administrative data

PBT assessment: overall result

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

Persistence

The ready biodegradability of the substance was investigated in a study according to OECD Guideline 301 B. The test item proved not to be readily biodegradable. However, at the end of the test the test item showed 54 % degradation indicating that the substance is most probably inherent biodegradable. Therefore, the available data lead to the conclusion that the substance is most probably not regarded as persistant.

Bioaccumulation

Bioaccumulation of the substance can be excluded based on its low logKow of 1.6

Toxicity

The substance is not classified as carcinogenic (Cat.1A or 1B) or toxic for reproduction (Cat.1A, 1B, or 2) according to regulation EC No. 1272/2008 (CLP), nor is there any evidence of chronic toxicity as identified by the classification as Specific Target Organ Toxicity after repeated exposure (STOT RE category 1 or 2) according to the same regulation.

Based on reliable results on short-term toxicity the lowest L(E)C50 for the substance was determined to be 58.9 mg/L (fish).

In accordance with the decision tree depicted in section R11.1.3.3 of ECHA's "Guidance on information requirements and chemical safety assessment", acute toxicity results >0.1 mg/L lead to a screening assignement of "presumably not T".
