PBT status:
the substance is not PBT / vPvB

Due to the rapid hydrolysis of the parent compound pivaloyl chloride (CAS 3282-30-2), the environmental assessment is mainly based on its hydrolysis product pivalic acid (CAS 75-98-9). Since pivalic acid is not readily biodegradable (according to OECD criteria) it should be regarded as potentially P/vP from a precautionary point of view until further data become available. Pivalic acid is not B/vB since it has a log Kow less than 3 (log Kow = 1.8; see IUCLID chapter 4.7). Pivalic acid is not T since the lowest chronic value available is >>0.01 mg/L (algae: 72-h NOEC = 246 mg/L), and the screening criteria for T are not fulfilled, based on the lowest available acute value being > 0.1 mg/L (invertebrates: 48-h EC50: 203 mg/L).


In conclusion, the parent compound pivaloyl chloride (CAS 3282-30-2) is considered to be neither PBT nor vPvB, based on the available data for the hydrolysis product pivalic acid (CAS 75-98-9).
