- Test substance administration:
Hair was clipped on the dorsal areas of the trunks one day before the application of the test substance. the test sites were median on the dorsal thoracal region.
Samples with approximately 0.5 g of the test substance were moistened with 1 mL deionised water and were placed on cellulose patches in a size of about 2.5 cm * 2.5 cm and were applied to the test sites. They were held in place by fixing them marginally with non irritating tapes. The application sies were covered semi-occlusively by a dressing.
Access by the animals to the application sites was prevented by a plastic collar.
At the end of the exposure period, the dressings, the tapes with the patches and the collars were removed, residual test substance was wiped off with wet Kleenex-tissues, if necessary.
Skin examinations:
The skins of the animals were examined for local alterations after the clipping procedure, one day before the application and immediately before application. the treated areas and the surrounding untreated skin (control area) of the animals were examined for erythema/eschar and oedema as well as for other local alterations approximately 1, 24, 48 and 72 hours after patch removal.
No further examinations were performed thereafter.
The skin was examined using a cold light source KL1500 electronic.
General examinations:
The animals were examined once daily for other than local changes of the skin. - Irritation parameter:

Reference
A light-blue staining of the skin at the application site was seen in all animals from 1h p.a. until a maximum of 24h after patch removal, but did not impede the xamination of the skin for erythema. The discoloration is directly attributed to a staining property of the test substance and not considered to be a toxic effect. Except for this, all exposed skin sites were normal at each examination term.

Reference
Cornea: Irreversible corneal alterations with scores of "2" were observed from 24 h to 72 h p.a. ; 6 d p.a. the score increased to "3". The affected area was one half to the whole cornea. Additionally a corneal neovascularisation, arising from the sclera was seen from 8 d to 21 d p.a. 75% of the cornea were homogeneously stained after an additional examintaion by instillation of fluorescein. This indicates a damage of the anterior corneal epithelium.
Iris: A sluggish reaction to the light (score "1") was noted from 24 h p.a. until 72 h p.a. From 6 d until 8 d p.a. no examinations were possible due to the corneal alterations. From 10 d until 21 d.p.a., the iris was normal.
Conjunctivae, redness: The animal was affected with scores ranging from "3" to "1", from 1 h p.a. onwards until a maximum of 10 d p.a.
Conjunctivae, chemosis: Swelling was noted from 1 h onwards until a maximum of 72 h p.a., starting with scores of "4" and afterwards decreasing.
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Additional information
Skin irritation:
Reference Bernat (2001) is considered as the key study for skin irritation and will be used for classification. Results do not meet the criteria for classification (mean value ≥ 2.0 for one endpoint for all animals or for the 2 endpoints in at least 2 animals) according to regulation (EC) 1272/2008 as skin irritant, hence no classification required.
Eye irritation:
One reliable in-vivo study described by Bernat (2001) (OECD 405; GLP compliant) is considered to be reliable without restrictions. The substance was determined to be severely irritating to the eye.
Justification for selection of skin irritation / corrosion endpoint:
