Results and discussion
Applicant's summary and conclusion
- Executive summary:
No specific study was performed on the absorption, distribution, metabolism and/or excretion (ADME) of WS400123, a complex mixture of components. Low to moderate absorption and systemic availability of WS400123 or some of its components after oral exposure has been concluded from small, non-adverse changes observed in some blood parameters in the subacute and subchronic toxicity studies in rats. Dermal absorption has been concluded from the sensitization response attained in a Local Lymph Node Assay (LLNA) in mice at non-irritating test concentrations of WS400123.
Exposure of humans to WS400123 by the inhalation route is unlikely, because of its very low vapour pressure (1 x 10-3Pa at 25°C), its decomposition at high temperature without boiling (above ca. 150°C) and because it is a highly viscous liquid.
All available study results gave no indication regarding the distribution, metabolic pathway, or excretion of WS400123.
Bioaccumulation was not investigated, but in view of its Log10Pow< +1, WS400123 is not considered to have a bioaccumulation potential.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
