Additional information

No studies are available with the substance itself, therefore information the constituent with CAS 85186-64 -7 is used.

In vivo skin irritation (similar to OECD 404 with CAS 85186-64 -7)

A pre-guideline study, similar to OECD 404 was performed. In this study 2 Vienna White rabbits were treated with ca. 1g (50% aqueous) test substance on the clipped skin of the upper third of the back. The exposure duration was 20 hours under occlusive conditions. After removal of the test patch, the substance was not removed. Observations were recorded after 24 hours and 8 days and the untreated skin was used as a control. After 24 hours no signs of erythema nor oedema were observed. The only local observation were black test substance residues. Based on these data, the substance was not considered to be irritating to the skin (BASF 1972).

In vivo eye irritation (similar to OECD 405 with CAS 85186 -64 -7)

A pre-guideline study, similar to OECD 404 was performed. In this study 2 Vienna White rabbits were treated with ca. 50 mg into the conjunctival sac of the right eyelid. The exposure lasted for 24 hours, after which the test substance was not washed out. Observations were recorded after 1 hour, 24 hours and 8 days and a talcum treated eye was used as a control. After 1 hour mild redness and corneal opacity was observed, which were both reversible within 24 hours. Mild redness was also observed in the control eyes. In the substance treated eyes, black test substance residues were observed. Based on these data, the substance was not considered to be irritating to the eyes (BASF 1972).

Justification for classification or non-classification

Based on the available data classification and labelling for skin and eye irritation is not warranted in accordance with EU Classification, Labeling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008
