Detailed information regarding the PBT/vPvB determination is summarised in the table (above). The substance has been shown to be readily biodegradable and therefore is not persistent. The substance has an octanol-water partition coefficient (log Kow) of 1.11, substantially below the screening criterion of 4.5, above which a substance may be considered to be bioaccumulative and very bioaccumulative; the substance has a predicted BCF of 2.508 L/kg, substantially below both the definitive BCF thresholds of 2000 L/kg for bioaccumulative and 5000 L/kg for very bioaccumulative. This substance does not meet the screening criteria for aquatic toxicity, as the lowest short-term L(E)C50value of 320 mg/L is substantially above the definitive criterion of L(E)C50< 0.01 mg/L and the screening criterion of L(E)C50< 0.1 mg/L for aquatic toxicity. The substance does not meet any of the criteria for mammalian toxicity in accordance with the CLP Regulation, i.e., carcinogenic (category 1A or 1B), mutagenic (category 1 or 1B), toxic for reproduction (category 1A, 1B or 2), or other evidence of chronic toxicity, i.e., specific target organ toxicity after repeated exposure (STOT RE category 1 or 2). Thus, the substance has been determined to be not persistent, not bioaccumulative and not toxic, and is considered to be not PBT and not vPvB.
