Results and discussion

Any other information on results incl. tables

There are no experimental toxicokinetic data available for the substance and this statement is based on the available physico-chemical and toxicological data. This comprises inter alia studies on skin irritation/corrosion, eye irritation, skin sensitization, in vitro mutagenicity and acute and repeated dose oral toxicity. The assumption on toxicokinetics follows the procedure indicated in the “Guidance on information requirements and chemical safety assessment chapter R.7c” of the ECHA guidance document (version 3.0, June 2017).
