- Hostacerin DGI was tested for primary skin irritation according to OECD test guideline 404 using three New Zealand albino rabbits. Only animals with intact skin were used. Each animal was treated with 0.5 mL undiluted Hostacerin DGI. The test item was applied over the whole surface of a 2.5 x 2.5 cm cellulose patch on piece of surgical plaster. The plaster was fixed to the prepared skin area and then covered with a semi-occlusive bandage. The exposure period was 4 hours. After the exposure all remnants of the test material were carefully removed from the skin with warm tap water. Examinations of skin took place after 30-60 minutes, 24, 48 and 72 hours after removal of the patches. Erythema and edema were evaluated numerically according to the score of Draize.

- The test material was tested for primary eye irritation in three New Zealand albino rabbits according to OECD test guideline 405. The animals had no ocular abnormalities. 0.1 mL of undiluted test substance was applied once to the conjunctival sac of the left eyes of three rabbits. The untreated eye served as a respective control. The exposure period was 24 hours. 24 hours after instillation and at all the designated examination times at which corneal examination with fluorescein sodium took place, the treated eyes were washed out thoroughly with isotonic saline at approx. 37°C. The eyes were also examined for corneal lesions under UV light after instillation of one drop of 0.01 % fluorescein-sodium solution.

Additional information
Skin irritation:
Data from an OECD 404 study in rabbits demonstrated that the test substance registered has no skin irritating potential under the test conditions. Two studies in rabbits performed with a prolonged exposure time of 24 hours can be regarded as a worst case condition. It could be demonstrated, that dermal application of 0.5 mL test substance to the rabbit’s skin for 24 hours did not lead to signs of irritation after application. Only the result of the study performed in 1980 has to be regarded as equivocal, but this result was not sufficient to warrant classification as a skin irritant. Although, the available human test data for skin irritation after a patch test are not required, the results support the overall result, that the test substance is not irritating to the skin.
Eye irritation:
In order to evaluate the eye irritation potential of the test substance registered two studies in rabbits are available. One study is performed according to guideline OECD 405 and one study according to Federal Hazardous Substances Act, 16 CFR, Section 1500.42. For the studies 0.1 mL of the test material was applied into one of each eye of three or six rabbits, i.e. in the key study or in the supporting study, respectively. In the key study the treated eyes were washed out 24 hours after application of the test item. The rabbits were observed for up to 72 hours to determine the grade of ocular reaction to the test material. All tested animals had a slight to mild positive reaction with the test material one hour after start of treatment which was fully reversible within 48hours.
In the supporting study the test material was found to produce mild positive reactions, such as erythema and swelling above normal, in four of six rabbits up to 48 hours. At the 72 hour observation time point all reactions were reversible.
An additional study performed in 1980 is used as supportive data. The test material registered was tested in different concentrations (i.e. undiluted, 10% and 0.1 % in physiol. Saline) in two rabbits per concentration. The assessment of the irritation potential was performed at 1, 7, 24, 48 and 72 hours and described. After application of the undiluted test substance mild to distinct reactions were found. Slight to distinct reddening and discharge were found after application of the 10% and the 1% solution. As the reversibility was not assessed under this study conditions the substance has slight irritation potential after the 72 hour observation. The result is assessed to be equivocal as no score numbering is given for findings and no recovery was performed.
However, the results on eye irritation studies are not sufficient to warrant classification.
Justification for selection of skin irritation / corrosion
endpoint:
The study is performed in accordance to OECD 404 and is well
documented.
Justification for selection of eye irritation endpoint:
The study is performed in accordance to OECD 405 and is well
documented.
Justification for classification or non-classification
Based on all the available test results for skin irritation and in accordance with the criteria for classification as defined in Annex I, Regulation 1272/2008, it is concluded, that the test substance registered does not require classification for skin irritation.
Based on all the available test results for eye irritation and in accordance with the criteria for classification as defined in Annex I, Regulation 1272/2008, it is concluded, that the test substance registered does not require classification for eye irritation.
