- Executive summary:
The liquid test material was spread onto patches and applied to the intact skin of a previously shaven rabbit for 4 hours under semi-occlusive conditions. The study was performed initially with one animal, which showed signs of irritation (erythema, edema, brittle skin, and small scales) and therefore no more animals were treated. The first examination of the treated skin followed 1 hour after patch removal. Thereafter, examinations were performed daily for a further 21 days. No signs of pain were observed after administration of the test material. Under the conditions of the present study erythema (scores 2 to 4) from day 1 up to the end of the study and edema (scores 1 to 3) from day 1 up to day 7 of the study occurred. Furthermore, small scales were observed from day 13 up to the end of the study and epithelization from day 15 up to the end of the study. Brittle skin from day 8 up to day 14 was seen at the site of application. The test material caused irritative skin effects.
Reference
Pretests:
Prior to testing the pH of the preparation was determined with pH-test strips. The pH was found to be about 5.
The test material was screened for its irritating potential using the hen's egg test on the chorioallantoic membrane (HET-CAM) as described below. Fertile hen eggs, on day 10 of incubation, provided the test system. The eggshell was entered above the air cell by a dentist's rotary and then pared off. The shell with the attached outer membrane and inner egg membrane was carefully opened. After the membrane had been moistened with isotonic sodium chloride solution, it was removed to expose the chorioallantoic membrane (CAM) of the fertilized egg, which lies immediately below. The CAM of fertilized and incubated hen eggs provides a suitable model for membranes with an intact and functional vascular system. The CAM has no nerve fibers in the early stages of development and is, thus, regarded as being insensitive to pain. In this model the cumulative irritation score of the test item was 0.00.

Additional information
Skin irritation
A WoE Approach was conducted to investigate the skin irritating properties of the substance:
A study according OECD TG 404 was conducted. The liquid test material was spread onto patches and applied to the intact skin of a previously shaven rabbit for 4 hours under semi-occlusive conditions. The study was performed initially with one animal, which showed signs of irritation (erythema, edema, brittle skin, and small scales) and therefore no more animals were treated. The first examination of the treated skin followed 1 hour after patch removal. Thereafter, examinations were performed daily for a further 21 days. No signs of pain were observed after administration of the test material. Under the conditions of the present study erythema (scores 2 to 4) from day 1 up to the end of the study and edema (scores 1 to 3) from day 1 up to day 7 of the study occurred. Furthermore, small scales were observed from day 13 up to the end of the study and epithelization from day 15 up to the end of the study. Brittle skin from day 8 up to day 14 was seen at the site of application. The test material caused irritative skin effects.
In addition, results for two in vitro tests are available. In a study performed comparable to OECD TG 439 the irritation potential of the test material was assessed by means of the Human Skin Model Test. Three tissues of the human skin model EPISKIN-SM were treated with either the test item, the negative or the positive control for 15 minutes. 15 µL of the liquid test item were applied to each tissue, spread to match the tissue size. 15 µL of either the negative control (deionised water) or the positive control (5% Sodium lauryl sulfate) were applied to each tissue. After treatment with the negative control, the absorbance values were well above the required acceptability criterion of mean OD 0.8 for the 15 minutes treatment interval thus showing the quality of the tissues. Treatment with the positive control induced a sufficient decrease in the relative absorbance as compared to the negative control for the 15 minutes treatment interval thus ensuring the validity of the test system. After treatment with the test item the relative absorbance values were not decreased (117.3%). Therefore, the test item is not considered to possess an irritant potential.
In an in vitro study performed according OECD TG 431 the corrosive potential of the test material was assessed by means of the Human Skin Model Test. Two tissues of the human skin model EPIDERM were treated with either the test item, the negative or the positive control for 3 minutes and 1 hour, respectively. 50 µL of the liquid test item were applied to each tissue, spread to match the tissue size. 50 µL of either the negative control (deionised water) or the positive control (8.0 N KOH) were applied to each tissue. After treatment with the negative control the absorbance values were well above the required acceptability criterion of mean OD ≥ 0.8 for both treatment intervals thus showing the quality of the tissues. Treatment with the positive control induced a decrease in the relative absorbance as compared to the negative control to 19.5% for the 3 minutes treatment interval and 8.2% for the 1 hour treatment interval thus ensuring the validity of the test system. After treatment with the test item the relative absorbance values were not decreased after 3 minutes treatment. After 1 hour treatment relative absorbance values were not reduced relevantly. Therefore, the test item is considered non-corrosive.
In conclusion, the substance was identified as skin irritant based on the available in vivo data.
Eye irritation
A study according OECD TG 405 was conducted. The liquid test material was tested for its eye irritating properties. Prior to testing, the hen's egg test on the chorioallantoic membrane was performed and no irritating potential could be detected. The test for primary eye irritation was performed initially with one animal and followed by the confirmatory test with two further animals. For the test of primary eye irritation, the test material was applied into the conjunctival sac of rabbits. The first examination of the eyes followed 1 hour after instillation. The other examinations of the eyes were performed daily for a further 7 days. No signs of irritation were observed at the cornea or iris. One animal showed redness of the conjunctiva (score 1) on day 2 and the other two animals showed redness (score 1) from the first reading up to day 3 of the experimental part. All animals showed chemosis (score 1) and discharge (score 3) one hour after instillation of the test material. All observations were fully reversible within the test period.No eye irritating potential could be detected.
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. Based on this data, the substance is considered to be classified for skin irritation Cat.2 (H315) under Regulation (EC) No 1272/2008, as amended for the twelfth time in Regulation (EU) 2019/521. No classification for eye irritation is required under Regulation (EC) No 1272/2008, as amended for the twelfth time in Regulation (EU) 2019/521.
