Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT status:
the substance is not PBT / vPvB

The substance is not PBT or vPvB as it is not expected to bioaccumulate in organisms based on its low Pow of <0 at 20°C and a measured BCF in carp of < 1.3. A weight of evidence assessment for persistence is appended to Section 13 of the CSR. This concludes that under aerobic conditions sulfolane can degrade completely to carbon dioxide, water, biomass and sulphate within the REACH persistence criteria for surface water or soil compartments. Under certain low nutrient or anaerobic conditions sulfolane may however persist in the environment. Sulfolane would meet the criteria for toxicity based on its classification as a Category 1 reprotoxicant.
