- Executive summary:
In an acute dermal irritation/corrosion study following OECD guideline 404 and in compliance with GLP, three New Zealand White rabbits were exposed to 0.5 ml of the test substance. A gauze patch (approx.12-16 cm) bearing the test article was applied to the right flank of each animal. A control gauze patch was applied to the contralateral flank. Both patches were moistened before application with test material. The patches were loosely covered with an aluminum foil (approx. 36 cm2) and held in place for 4 hours by an adhesive tape. The animals were checked daily for systemic symptoms and mortality. The skin reactions were evaluated 1, 24, 48, and 72 hours after removing the gauze patches according to the OECD scoring system. Under the experimental conditions employed the test substance induced mild erythema and edema reactions revesible within 48 hours when applied to the clipped albino rabbit skin. Because the mean values of the recordings 24 to 72 hours after application are below the threshold of significance, the test article is considered as not irritating to the rabbit skin.

- Interpretation of results:

- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the experimental conditions employed the test article induced mild irritation of the cornea and conjunctiva below the threshold of signifcance and is therefore regarded as not irritating to the rabbit eye.
- Executive summary:
In a GLP-compliant eye irritation study performed according to OECD guideline 405, three New Zealand White rabbits were treated with 0.1 ml of the test article. The test article was placed into the conjunctival sac of the left eye of each animal; the lids were then held together for about one second in order to prevent loss of the test material. The right eye remained untreated and served as a control. The ocular reactions were evaluated 1, 24, 48, and 72 hours after instillation and animals were checked daily for signs of systemic toxicity. Because reactions were observed within 72 hours after instillation of the test article, the observation period was extended to 10 days. Instillation of the test substance caused minimal corneal irritation in 2/3 animals at the 1-hour time point, reversible within 24 hours. Conjunctival effects were redness and chemosis in all three animals; chemosis was reversible after 24 hours and redness after 10 days. Since the observed ocular effects were below the threshold of significance, the test article is classified as not irritating.

Additional information
Skin: In a GLP-compliant primary dermal irritation study (OECD 404, Ciba-Geigy, 904254), 3 female New Zealand White rabbits were dermally exposed to 0.5 mL of the test substance for 4 hours under occlusive conditions. Animals were then observed for 3 days. Irritation was scored by the method of Draize as described in the OECD guideline 404. Minimal dermal reactions were recorded below the threshold of significance. The mean score for the 24, 48 and 72 h reading for erythema was 0.2 and for edema was 0. The skin reactions observed were reversible within 48 days. Based on the results of this study, the test article is regarded as not irritating to the rabbit skin.
Eye: A GLP-compliant eye irritation test was performed with three male New Zealand White rabbits according to OECD 405 (Ciba-Geigy, 904253). Eyes were left unwashed after application of 0.1 mL of test material and the animals were observed 10 days. The mean scores for the 24, 48 and 72 h readings for iritis, cornea opacity and conjunctivae chemosis were 0 at any of this reading time points. For conjunctivae redness the mean score for the 24, 48 and 72 h reading was 1. The eye reactions observed were reversible until the end of the observation period on day 10. In this study, the test substance is not an eye irritant.
