The UVCB substance WS400123 did not exhibit toxic effects in a
subchronic oral toxicity study up to and including the highest
recommended dose of 1000 mg/kg/day. Therefore, a DNEL for systemic
toxicity cannot be derived. However, WS400123 showed skin-sensitizing
potential in a local lymph node assay in mice. Therefore, dermal contact
has to be avoided. Exposure by inhalation is not expected because the
substance has a very low vapour pressure.
