Administrative data

short-term repeated dose toxicity: dermal
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
a short-term toxicity study does not need to be conducted because a reliable sub-chronic (90 days) or chronic toxicity study is available, conducted with an appropriate species, dosage, solvent and route of administration
Justification for type of information:
In accordance with column 2 of REACH Annex IX, the test repeated dose toxicity after dermal application (required in section 8.6) does not need to be conducted as repeated dose toxicity studies for oral application are available. Potassium cyanate is not irritating and not sensitizing to the skin. No dermal effects are expected for repeated dose application to the skin and a low dermal absorption is expected due to the physico-chemical properties of the substance.
