Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

QSAR estimation using the BCFBAF v3.01 of the EPISUITE 4.1 indicate that the BCF of sodium cumenesulphonate is 3.16 L/kgwwt. This is well below the threshold for Bioaccumulation (B) for the PBT determination.

Fish bioconcentration studies conducted at two exposure concentrations with sodium xylene

sulfonate and sodium toluene sulfonate reported BCF values of <2.3.

These experimental and estimated BCF values suggest that sodium cumenesulphonate has a low potential for bioaccumulation.

The likelihood of bioaccumulation is considered to be very low. Based on the evidence confirming bioaccumulation is unlikely to occur in aquatic organisms, the endpoint for terrestrial organisms is also waived.

Key value for chemical safety assessment
