Swelling with lids about half closed was observed in all animals one hour after administration. In addition, serous-colorless eye discharge was noted. 72 hours after administration all signs of irritation had completely disappeared.

Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0.0 / 0.0 / 0.0 for cornea score; 0.0 / 0.0 / 0.0 for iris score; 1.0 / 1.0 / 1.0 for conjunctivae score and 0.0 / 0.0 / 0.0 for chemosis score.

Additional information

Skin irritation

A key study was identified (Hofmann, 1986). In this skin irritation study performed according to OECD Guideline 404, 500 mg of test substance in 0.3 ml of physiological saline was applied to the clipped skin of three New Zealands White rabbits under a semi-occlusive cover. After a 4 -hour exposure period, the remaining test substance was removed with lukewarm tap water. No reactions were observed.

Eye irritation

A key study was identified (Kauffmann, 2001). In this eye irritation study was performed according to OECD Guideline 405 and in compliance with GLP. One eye of three rabbits each was exposed to 100 mg of the test substance for 24 hours. One hour up to 48 hours after administration the conjunctivae of all animals showed definitely injected blood vessels up to diffuse crimson color, so that individual vessels were not easily discernible. Swelling with lids about half closed was observed in all animals one hour after administration. In addition, serous-colorless eye discharge was noted. 72 hours after administration all signs of irritation had completely disappeared.

Justification for classification or non-classification

Harmonized classification:

The substance has no harmonized classification for skin or eye irritation according to the Regulation (EC) No. 1272/2008.

Self classification:

Skin irritation

Based on the available data no additional self-classification is proposed regarding skin irritation according to the Annex VI of the Regulation (EC) No. 1272/2008 (CLP) and to the GHS.

Eye irritation

Based on the available data no additional self-classification is proposed regarding eye irritation according to the Annex VI of the Regulation (EC) No. 1272/2008 (CLP) and to the GHS.

Respiratory irritation

No data was available.
