Endpoint summary
Administrative data
Description of key information
The test substance was investigated in vivo in rabbits for its skin irritation/corrosion and eye irritation/ corrosion potential according to international accepted guidelines.
Skin irritation: For the skin, no irritation potential was observed under selected testing conditions.
Eye irritation: For the eye, a single application produced slight but transient effects which were fully reversible within the observation period. Therefore the test substance was considered to be not irritant to the eye.

0.1 mL (per animal) of test item was measured with a syringe and applied undiluted. The pH of the test item was measured and was found to be 10.69. - Duration of treatment / exposure:
- 0.1 mL of test item was placed in the conjunctival sac of the left eye of each animal after gently pulling the lower lid away from the eyeball. The lids were then gently held together for about one second to prevent loss of test item. The right eye remained untreated and served as the reference control. The treated eyes were not rinsed after instillation. As it was suspected that the test item might produce irritancy, a single animal (one female) was treated first.

- Irritant / corrosive response data:
- No abnormal findings were observed in the cornea or iris of any animal at any of the measurement intervals. Moderate reddening of the conjunctivae was noted in the treated eyes of all animals one hour after test item instillation. The reddening persisted as moderate in two animals on the following day and had faded into slight in one animal at this time. Slight reddening of the conjunctivae was still present in the treated eyes of the three animals at the 48- hour reading. Obvious swelling (chemosis) of the conjunctivae with partial eversion of the lids was observed in two of the animals one hour after the treatment. The swelling persisted as slight in one animal at the 24- hour examination. Moderate or slight reddening of the sclerae was present in all test animals at the 1- hour reading and persisted in two animals still in the 24- hour evaluation. Slight or moderate ocular discharge was noted in the three test animals one hour after instillation was still present in one animal at the 24- hour reading. No abnormal findings were observed in the treated eye of any animal 72 hours after treatment at the end of the observation period for all animals. No staining of the eyes or test item remnants were noted at any examination. No corrosion of the cornea was observed at any of the reading times. The bod weights of all rabbits were considered to be within the normal range of variability.

Additional information
Skin irritation
The primary skin irritation potential of the test substance was investigated according to OECD 404, adopted in 2002. The test substance was applied by topical semiocclusive application of 0.5 mL to the intact left flank of each of three young adult New Zealand White rabbits. The duration of treatment was four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours after removal of the dressing. The mean score was calculated across 3 scoring times (24, 48 and 72 hours after patch removal) for each animal for erythema/ eschar grades and for oedema grades, separately. The mean erythema/ eschar score and the mean oedema score were 0.00 for each of the three animals. The application of the test item to the skin resulted in a very slight erythema in one animal. This effect was reversible and no longer evident 24 hours after treatment. Two animals remained completely negative. The test item caused no staining of the treated skin. No corrosive effects were noted on the treated skin of any animal at any of the measuring intervals and no clinical signs were observed. Thus, the test substance did not induce significant or irreversible damage to the skin.
Eye irritation
The primary eye irritation potential of the test substance was investigated according to OECD 405, adopted in 1997. The test substance was applied by instillation of 0.1 mL into the left eye of each of three young adult New Zealand White rabbits. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours after test item instillation. The mean score was calculated across 3 scoring times (24, 48 and 72 hours after instillation) for each animal for corneal opacity, iris, redness and chemosis of the conjunctivae, separately. The individual mean scores for corneal opacity and iris were 0.00 for all three animals. The individual mean scores for the conjunctivae were 1.00, 0.67 and 1.00 for reddening and 0.33, 0.00 and 0.00 for chemosis, respectively. The instillation of the test item into the eye resulted in mild to moderate, early- onset and transient ocular changes, such as reddening of the conjunctivae and sclerae, discharge and chemosis. These effects were reversible and were no longer evident 72 hours after treatment, the end of the observation period for all animals. No abnormal findings were observed in the cornea or iris of any animal at any of the examinations. No corrosion was observed at any of the measuring intervals. No staining of the treated eyes by the test substance was observed and no clinical signs were observed. Thus, the test substance did not induce significant or irreversible damage to the rabbit eye.
Justification for selection of skin irritation / corrosion endpoint:
GLP and guideline compliant.
Justification for selection of eye irritation endpoint:
GLP and guideline compliant.
Justification for classification or non-classification
Based on the available data the test substance is considered to be “not irritating” to rabbit skin. Therefore there is no need for classification and labeling acorrding to Directive 67/548/EEC (DSD) and Regulation (EC) No 1272/2008 (CLP).
