Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

The hydrolysis was measured in a standard OECD 111 test. The half-life is > 1 year.

The biodegradation of BBSA in water was determined in a 28 day ready-biodegradability test with carbon dioxide evolution (modified Sturm test). The substance was biodegraded for 12-23% after 28d, hence the substance is not considered ready biodegradable.

The biodegradation of BBSA was also determined in a standard simulation test in natural water (OECD 309). The mineralisation rate was negligible. The DT50 values were determied to be 858 days (at 10μg/L) and 985 days (at 95μg/L) in the water phases. Therefore, N-butylbenzenesulphonamide is to be considerd very persistent. Further persistency testing has not been performed.

BBSA has a low log Kow of 2.01, and so a low potential for adsorption to soil and sediment.
