Endpoint summary
Administrative data
Description of key information
A key study on skin irritation with the analogue substance octanoic acid, zinc salt, basic; demonstrate a lack of an irritation/corrosion potential. A key study on eye irritation indicates an irritating potential of the analogue substance octanoic acid, zinc salt, basic; effects are reversible. Furthermore, results of the histopathological examination of lung tissue following acute exposure to the structural analogue zinc dilaurate via inhalation (OECD 436 test, reported under acute inhalation toxicity) do not indicate an irritative potential to the respiratory tract.

Additional information
Justification for classification or non-classification
Zinc dioctanoate as slightly soluble zinc compound is not irritating or corrosive to the skin but irritating to the eyes. Therefore, the substance is classified as eye irritant category 2 (H319 Causes serious eye damage) according to EC Regulation No. 1272/2008.
