- TEST SITE
Four days before treatment, one flank was clipped. The skin of the animals was examined one day before treatment, and regrown fur of all animals was again clipped. Animals with overt signs of skin injury or marked irritation which may have interfered with the interpretation of the results were not used in the test. On the day of treatment, 500 mg of the test item was placed on a surgical gauze patch, which was applied to the intact skin of the clipped area. The patch was covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and anchored with tape.
REMOVAL OF TEST SUBSTANCE
The duration of treatment was 4 hours. Then the dressing was removed and the skin was flushed with lukewarm tap water to clean the application site so that any reactions (erythema) were clearly visible at that time.
OBSERVATION TIME POINTS
1 hour after removal, after 24, 48, 72 hours, and then daily up to experimental day 7.
Viability/Mortality/Clinical signs: Daily from delivery of the animals to the termination of test.
Body weights: At start of acclimatization, on the day of application and at termination of observation.
Necropsy: Not performed as animals were sacrificed at termination of observation.
SCORING SYSTEM: The skin reaction was assessed according to the numerical scoring system
(Erythema: 0= no erythema, 1= very slight erythema, 2= well defined erythema, 3= moderate to severe erythema, 4= severe erythema. Edema: 0= no edema, 1= very slight edema, 2= slight edema, 3= moderate edema, 4= severe erythema) listed in the EU Regulation (EC) No 1272/2008 (CLP), as amended for fifteenth time in Regulation (EU) No 2020/217, approximately 1, 24, 48 and 72 hours, as well as 7 days after the removal of the dressing, gauze patch and test item. - Irritation parameter:

- - pH measurements: Prior to the application, the pH of the test item was determined at a concentration of 1% in water with a pH test strip (E. Merck, D-64271 Darmstadt / Germany). The pH was found to be 5.
- Other adverse local effects: Very slight erythema was observed at the test site of two animals 1 hour after treatment (table 1). The test item did not, however, elicit any signs of irritation at the application site of any animal at the 24-, 48-, 72-hour or 7-day readings. The mean values from 24 to 72 hours were, therefore, 0 for erythema and 0 for edema (table 2). - Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item did not induce significant or irreversible damage to the rabbit skin and is considered to be "not irritating" to rabbit skin.
- Executive summary:
The primary skin irritation potential of the test item was investigated by topical semi-occlusive application of 0.5 g 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, 72 as well as 7 days after removal of the dressing. The application of the test item caused very slight erythema at the test site of two animals 1 hour after treatment. The test item did not, however, elicit any signs of irritation at the application site of any animal at the 24-, 48-, 72- hour or 7-day readings. The mean values from 24 to 72 hours were, therefore, 0 for erythema and 0 for edema. The test item caused no staining of the treated skin. No corrosive effects were noted on the treated skin of any animal at any measuring interval. Thus, the test item did not induce significant or irreversible damage to the rabbit skin. Based upon the referred classification criteria (EU Regulation (EC) No 1272/2008 (CLP), as amended for fifteenth time in Regulation (EU) No 2020/217), the test item is considered to be "not irritating" to rabbit skin.

- Irritant / corrosive response data:
- Application of the test item to healthy rabbit conjunctivae resulted in a primary eye irritation score of 1. No abnormal findings were observed in the cornea or iris of any animal at any of the measuring intervals (table 1). Slight to moderate reddening of the conjunctivae was observed in all animals 1 hour after treatment. Slight reddening continued to be observed in all animals but gradually diminished to clear at the 7-day reading (table 1). Swelling of the conjunctivae (slight with partial eversion of lids or with lids about half-closed) was apparent in all animals at the 1-hour reading. Swelling persisted in one animal up to 48 hours after treatment (table 1). Assessment of the sclera was not possible in one animal at the 1-hour reading due to swelling of the conjunctiva. Moderate reddening was, however, subsequently observed in this animal at the 24- and 48-hour readings but diminished to clear 7 days after treatment. Moderate reddening was similarly observed in the remaining two animals 1 hour after treatment but cleared in one animal at the 24-hour reading and in the other animal at the 48-hour reading (table 1). A slight to moderate waterly discharge was present in all animals 1 hour after treatment and a slight waterly discharge was still evident in one animal at the 24-hour reading. No abnormal findings were observed in the treated eye of any animal 7 days after treatment, the end of the observation period for all animals. No corrosion of the cornea was observed at any of the reading times.
- Other effects:
- - Lesions and clinical observations: no clinical signs of systemic toxicty were observed in the animals during the study and no mortality occured
- white remnants of the test item were observed in the eye or conjunctival sac of all animals 1 hour after treatment and continued to be observed in one animal up to the 24-hour reading - Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item did not induce significant or irreversible damage to the rabbit eye and is considered to be "not irritating" to the rabbit eye.
- Executive summary:
The primary eye irritation of the test item was investigated by instillation of 0.1 g into one eye of each of three young adult New Zealand White rabbits. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours, as well as 7 days after test item application. The scores of each animal at the following reading times (24, 48 and 72 hours) were used in calculating the respective mean values for each type of lesion. The primary eye irritation score was calculated by totaling the mean cumulative scores at 24, 48 and 73 hours and then dividing the resulting total by the number of data points. The primary eye irritation score was 1.00 (max 13). The eye reactions (mean values from 24 to 72 hours) consisted of grade 0.00 corneal opacity, grade 0.00 iris lesions, grade 0.67 redness of the conjunctivae and grade 0.33 chemosis of the conjunctivae. The instillation of the test item into the eye resulted in mild, early-onset and transient ocular changes, such as reddening of the conjunctivae and sclerae, discharge and swelling. These effects were reversible and were no longer evident 7 days 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 reading. No corrosion was observed at any of the measuring intervals. No staining of the treated eyes by the test item was observed. Thus, the test item did not induce significant or irreversible damage to the rabbit eye. Based upon the referred classification criteria (EU Regulation (EC) No 1272/2008 (CLP), as amended for fifteenth time in Regulation (EU) No 2020/217), the test item is considered to be "not irritating" to the rabbit eye.

Additional information
Skin irritation/corrosion
The primary skin irritation potential of the test item was investigated by topical semi-occlusive application of 0.5 g 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, 72 as well as 7 days after removal of the dressing. The application of the test item caused very slight erythema at the test site of two animals 1 hour after treatment. The test item did not, however, elicit any signs of irritation at the application site of any animal at the 24-, 48-, 72- hour or 7-day readings. The mean values from 24 to 72 hours were, therefore, 0 for erythema and 0 for edema. The test item caused no staining of the treated skin. No corrosive effects were noted on the treated skin of any animal at any measuring interval. Thus, the test item did not induce significant or irreversible damage to the rabbit skin. Based upon the referred classification criteria (EU Regulation (EC) No 1272/2008 (CLP), as amended for fifteenth time in Regulation (EU) No 2020/217), the test item is considered to be "not irritating" to rabbit skin.
Eye irritation/corrosion
The primary eye irritation of the test item was investigated by instillation of 0.1 g into one eye of each of three young adult New Zealand White rabbits. Scoring of irritation effects was performed approximately 1, 24, 48 and 72 hours, as well as 7 days after test item application. The scores of each animal at the following reading times (24, 48 and 72 hours) were used in calculating the respective mean values for each type of lesion. The primary eye irritation score was calculated by totaling the mean cumulative scores at 24, 48 and 73 hours and then dividing the resulting total by the number of data points. The primary eye irritation score was 1.00 (max 13). The eye reactions (mean values from 24 to 72 hours) consisted of grade 0.00 corneal opacity, grade 0.00 iris lesions, grade 0.67 redness of the conjunctivae and grade 0.33 chemosis of the conjunctivae. The instillation of the test item into the eye resulted in mild, early-onset and transient ocular changes, such as reddening of the conjunctivae and sclerae, discharge and swelling. These effects were reversible and were no longer evident 7 days 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 reading. No corrosion was observed at any of the measuring intervals. No staining of the treated eyes by the test item was observed. Thus, the test item did not induce significant or irreversible damage to the rabbit eye. Based upon the referred classification criteria (EU Regulation (EC) No 1272/2008 (CLP), as amended for fifteenth time in Regulation (EU) No 2020/217), the test item is considered to be "not irritating" to the rabbit eye.
Justification for classification or non-classification
Classification, Labeling, and Packaging Regulation (EC) No 1272/2008
The available data for skin and eye irritation are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. The test item is not considered to be classified for skin and eye irritation/corrosion according to EU Regulation (EC) No 1272/2008 (CLP), as amended for fifteenth time in Regulation (EU) No 2020/217.
