Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Name:
- N-butylbenzenesulphonamide
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Reference substance:
- N-butylbenzenesulphonamide
- PBT status:
- the substance is not PBT / vPvB
- Justification:
BBSA is not readily biodegradable as shown in a ready biodeg study (OECD 301). Additionally, the degradation half-life of BBSA is > 180 days in fresh water, as demonstrated in the screening test in fresh water (OECD 309) --> BBSA is very Persistent (vP)
BBSA is not expected to bioaccumulate. BBSA has a low log Kow of 2.01 (see section 5.3.1) and toxicokinetic study indicates no bioaccumulation (see section 7.1.1) --> BBSA is not Bioaccumulative (not B)
BBSA does not fulfil the screening criteria as toxic. The substance is not classified for human health endpoint and the lowest reported EC10 is well above 0.01 mg/L.
Based on the above, BBSA does not fulfil the criteria for PBT or vPvB since the substance is not predicted to be bio-accumulative.
