Additional information

In vivo data generated by the Kolmar Research Center and published by BUA (CFTA 1967) for DEHA do not show a skin or eye irritation potential of the substance. Undiluted test substance was applied for 24 hours to the intact or abraded skin of 6 rabbits. Despite the long exposure time only slight erythema were observed after removal of the patch, severity of which decreased further within the following 72 hours. No difference between intact or abraded skin was detected. The maximum value for the mean primary irritation index was 0.83. Instillation of 0.1ml of DEHA into the eyes of 6 albino rabbits did not elicit a visible response.

Justification for classification or non-classification

The findings in both the skin and eye irritation studies do not meet the critera for classification as a skin irritant or as an eye irritant according to 67/548/EEC or EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
