PBT assessment: overall result

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

PBT and vBvP Assessment of the main component

A substance is identified as a PBT substance if it fulfils all criteria described in REACH Annex XIII. According to information summarized in the sections 4 to 7, 6PPD fulfils the T criterion and does not fulfil the P or B criteria. Hence 6PPD is not PBT.

A substance is identified as a vPvB substance if it fulfils both the vP and the vB criteria as described in REACH Annex XIII.

Neither the vP criterion nor the vB criterion is fulfilled. Therefore, 6PPD is not vPvB.

PBT and vBvP Assessment of degradation products

Several degradation products, formed by hydrolysis have been described: 6QDI, 4 -HDPA, Aniline, 1,3 -Dimethylbutylamine, p-Benzoquinone and p-Hydroquinone. It could be demonstrated that these degradation products are not PBT and not vPvB.

PBT and vBvP Assessment of Impurities >0.1%:

According to the REACh regulation, also impurities >0.1% are subject to PBT and vBvP assessment. The relevant impurities are listed inTable 3 of the CSR. Chemical structures can be found in IUCLID chapter 1.2.

 

  • N-(4-aminophenyl)aniline (EC no.: 202-951-9) (common name 4-ADPA) is a substance which is already listed in the ECHA dissemination tool. The substance is not readily biodegradable but inherently biodegradable with more than 70% DOC removal in 7 days independent from adsorption. The calculated BCF is 7. The most sensitive long-term effect concentration was observed in a daphnia reproduction test with a 21d-NOEC of 0.04 mg/L. Hence, the substance is neither PBT nor vBvP.
  • Aniline, (EC no.: 200-539-3). The substance is well known and already listed in the ECHA dissemination tool. It is readily biodegradable and it is not bioaccumulative. Hence, the substance is neither PBT nor vBvP
