- Executive summary:
During an initial test using one female albino rabbit a sequential application (exposure time 3 min., 1 h. and 4 h.) of the test substance was carried out on one site of the right back area each. The skin was examined for signs of irritation straight after as well as 1 h., 24 h., 48 h. and 72 h. after the termination of exposure. Since the animal did not show signs of skin irritation and no full thickness destruction of the skin within the observation period of 72 hours it was decided to carry out a confirmatory test with two additional animals in order to allow a categorization of the test item based on the classification criteria.Two female albino rabbits were exposed to the test item at one skin site on the back during the confirmatory test. After 4-hour exposure time the test item was removed and the skin was examined 1 h., 24 h., 48 h. and 72 h after the termination of exposure. No skin reactions were observed in these animals, too. Under the experimental conditions described in this final report, the mean score for erythema was 0.0 and for oedema 0.0. Based on the results of the study described in this report and according to the directive of the EEC commission 2001/59/EC from August 6th, 2001 the test substance was not skin irritating and shall not be classified as skin irritating.

- Executive summary:
In a OECD 405 study, 0.1 mL of the test substance was instilled into the conjunctival sac of one eye of each of 3 Little Russian rabbits for 24 hours. Eyes were washed with 20 ml 0.9 % sodium chloride solution at the end of the exposure period. Eye irritation was scored 1 h, 24 h, 48 h, 72 h after instillation of the test substance using the grading system of OECD test guideline 405 (Acute Eye Irritation/Corrosion).
One hour after the application of the test item animal No. 2928 showed scattered or diffuse opacity quarter the area of the cornea of the cornea on more than one quarter. Additionally some hyperaemic, conjunctival blood vessels were observed. Animals No. 3164 and No. 3163 showed some hyperaemic, conjunctival blood vessels only. 24 h. after the application of the test item animals No. 2928, No. 3164 and No. 3165 showed some hyperaemic, conjunctival blood vessels. 48 and 72 h. after the application of the test item animals No. 2928, No. 3164 and No. 3163 were free of any signs of eye irritation.
In this study, the test substance is not irritating to the eye according to EU regulations.
This study is assessed as acceptable. It satisfies the guideline requirements (OECD TG 405) for an acute eye irritation/corrosion study.

Additional information
Based on the results of the skin irritation study according to OECD 404 the target substance was not skin irritating and shall not be classified as skin irritating. This result is supported by a human patch test, in which no skin irritation effects were observed in any of the subjects after 48 hours exposure.
In an eye irritation study according to OECD 405 the target substance is not irritating to the eye according to EU regulations.
Justification for selection of skin irritation / corrosion
endpoint:
There is only one study available for the target substance.
Justification for selection of eye irritation endpoint:
There is only one study available for the target substance.
Justification for classification or non-classification
The target substance was neither skin nor eye irritating and therefore does not require classification according to EU regulations (Directive 67/548/EEC and Regulation (EC) No 1272/2008.
