Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The aromatic sulphonic acids have very low logPow values and are therefore not expected to be sorbed onto sediments. These substances are readily biodegraded and therefore will not accumulate. A significant distribution into the sediment compartment is not predicted and exposures to sediment dwelling organisms is expected to be comparable to pelagic species.  Hence sediment toxicity testing is not warranted.  

Key value for chemical safety assessment
