Applicant's summary and conclusion
Validity criteria
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- Not expected to biodegrade fast.
- Executive summary:
TBPA is not expected to be readily biodegradable. This prediction is consistent with the lack of evidence for biodegradation seen in a soil study. TBPA is expected to undergo rapid hydrolysis to TBPA-acid, which is not expected to biodegrade fast.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
