Additional information

Skin irritation

No studies on skin irritation have been performed with the substance and none are proposed, based on scientific considerations and for reasons of animal welfare. In accordance with section 8.1, column 2, Annex VII of regulation (EC) 1907/2006), the in-vitro eye irritation study does not need to be conducted as the available information indicates that the criteria are met for classification as corrosive to the skin. In accordance with section 8.1.1, column 2, Annex VIII of regulation (EC) 1907/2006), the in-vivo eye irritation study does not need to be conducted as the substance is a strong base (pH≥11.5).

Eye irritation

No studies on eye irritation have been performed with the substance and none are proposed, based on scientific considerations and for reasons of animal welfare. In accordance with section 8.2, column 2, Annex VII of regulation (EC) 1907/2006), the in-vitro eye irritation study does not need to be conducted as the available information indicates that the criteria are met for classification as corrosive to the eyes. In accordance with section 8.2.1, column 2, Annex VIII of regulation (EC) 1907/2006), the in-vivo eye irritation study does not need to be conducted as the substance is classified as corrosive to the skin and it is provided that the registrant classified the substance as eye irritant. Furthermore, the substance is a strong base (pH≥11.5).


Effects on skin irritation/corrosion: corrosive

Effects on eye irritation: corrosive

Justification for classification or non-classification

Skin irritation:

The test substance should be classified as corrosive to the skin by worst case (pH >11.5). Therefore, the in vivo skin irritation was not conducted due to animal welfare. Hence, the substance has to be classified as skin corrosive 1A substance and labeled with H314: Causes severe skin burns and eye damage.

 

Eye irritation:

The test substance is classified as corrosive to the skin by default. Therefore, the in vivo eye irritation was not conducted due to animal welfare. Hence, the substance has to be classified as eye damage 1 and labeled with H318: Causes serious eye damage which was already covered by the labeling H314: Causes severe skin burns and eye damage.

Respiratory irritation:

The classification as respiratory irritant is normally covered under the endpoint specific target organ toxicity- single exposure and repeated exposure. For substances and mixtures classified as skin corrosive, the additional labelling EUH071: Corrosive to the respiratory tract should be used due to the fact that no acute inhalation test data is available.
