Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because based on structure, surface activity is not expected or cannot be predicted
the study does not need to be conducted because surface activity is not a desired property of the material

Description of key information

According to REACh Annex VII / column 2, the study needs only to be conducted if based on structure , surface activity is expected or can be predicted.
Chlorobenzene is not intended to be used as a surfactant (i.e. not a desired property), and it does not contain groups (such as distinct polar and non-polar parts) indicating that it will have surface-active properties in solution.
Therefore testing is deemed unnecessary.

Key value for chemical safety assessment

Additional information

Supporting literature sources provide a surface tension value of ca 33 mN/m, but test conditions, in particular concentration, are not specified. Therefore they were not assessed as valid, and could not be regarded as key studies. Considering the low solubility of the substance (538 mg/L), no extrapolation can be made on its surface-active potential, since in the worst case ST could have been measured on pure, which would not be comparable at all with the required concentration of 90% saturation, according to guideline criteria.
