Description of key information
Two studies in rabbits were performed to evaluate irritating or corrosive properties of the test material to skin or eyes (EU guideline B.4 and B.5; GLP). Application of the test substance caused slight erythema of the skin, dulling of the cornea and mild conjuctival irritation. All reactions on skin and eyes had resolved within 2 days. Therefore, the substance is considered to be non-irritating.

- Irritant / corrosive response data:
- Dulling of the normal lustre of the cornea was seen in two animals one hour after instillation only.
No other corneal damage or iridial inflammation was observed.
Considerable swelling with partial eversion of the eyelids was seen in one animal one hour after instillation only. Temporary mild conjunctival reactions were seen in the remaining animals.
The eyes were normal two days after instillation - Other effects:
- There were no signs of toxicity or ill health in any rabbit during the observation period.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Instillation of the test substance into the rabbit eye elicited dulling of the cornea and mild transient conjunctival irritation. All reaction has resolved within 2d. The substance is therefore considered to be non-irritating.
- Executive summary:
A study was performed to assess the eye irritation potential of the test substance to the rabbit.
The method followed was that described in EEC Methods for the determination of toxicity, Annex to Directive 92/69/EEC (OJ No. L383A, 29.12.92), Part B, Mediod B.5. Acute toxicity (eye irritation). The study was conducted under GLP conditions.
Three rabbits were each administered a single ocular dose of 76 mg of the test substance and observed for seven days after instillation. A single instillation of the test material into the eye of the rabbit elicited dulling of the cornea and transient mild conjunctival irritation. All reactions had resolved 2 days after instillation.

Additional information
Skin irritation:
A study was performed to assess the skin irritation potential of the test substance to the rabbit. The method followed was that described in EEC Methods for the determination of toxicity, Annex to Directive 92/69/EEC (OJ No. L383A, 29.12.92), Part B, Method B.4. Acute toxicity (skin irritation). The study was performed under GLP conditions.
Three rabbits were each administered a single dermal dose of 0.5 g of the test substance and observed for four days.
A single semi-occlusive application of the test substance to intact rabbit skin for four hours elicited transient very slight dermal reactions. All reactions had resolved by Day 2.

Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. In animal studies with rabbits very slight reactions were observed which fully resolved within 2 days after application of the test substance. As a result the substance is not considered to be classified for irritation under Regulation (EC) No. 1272/2008.
