Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Conclusion on P / vP properties: vP (and P)
Bis(4-(1,1,3,3-tetramethylbutyl) phenyl) amine is not readily biodegradable (20% degradation in 28 days) but is considered to be inherently biodegradable. Based on its chemical structure, which contains no hydrolysable groups the substance does not undergo hydrolysis. .Bis(4-(1,1,3,3-tetramethylbutyl) phenyl) amine is therefore considered to be very Persistant (vP) based upon the information available.
Conclusion on B / vB properties: not B/vB
The BCF is calculated as 179.4 (Log Pow 2.254) and therefore does not meet the criteria for consideration as B or vB.
Conclusion on T properties: not T
No evidence of toxicity has been reported in any study on bis(4-(1,1,3,3-tetramethylbutyl) phenyl) amine.
- Likely routes of exposure:
The primary route of Bis(4 -(1,1,3,3 -tetramethylbutyl) phenyl) amine release will be to wastewater.
Bis(4 -(1,1,3,3 -tetramethylbutyl) phenyl) amine may be released to air through use processes, however, the vapour pressure is 0.000011 Pa at 25 ºC and therefore air exposure is expected to be negligible.
Release to soil may occur from spreading of STP sludge’s, however this is advised against.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
