- TEST SITE
- Area of exposure: To each of two 16-layer gauze patches (2.5 x 2.5 cm) 0.5 ml of the test article was applied
- % coverage: No details provided in report
- Type of wrap if used: To each of two 16-layer gauze patches (2.5 x 2.5 cm) 0.5 ml of the test article was applied, and the patches were placed on the appropriate test site on the back of each rabbit. The gauze patches were secured with 2.5 cm wide adhesive Gothaplast tape and fixed with Gothaplast tape, 5 cm width, loosely wound round the trunk.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): After an exposure time of 4 hours the tape and patches were removed, the test fields were marked and the treated skin was cleaned with mild soap and lukewarm water.
- Time after start of exposure: Patches and tape were removed 4 hours after start of exposure
SCORING SYSTEM: Skin reactions were read 1 hour after removal of patches and washing of treated skin using the scale outlined in the attached report. Reading was also made 24, 48 and 72 hours after termination of exposure. The respective scores for erythema and oedema formation for the 3 readings 24, 48 and 72 hours of each rabbit were summed up separately and divided by 6. The results are the mean scores for erythema and oedema formation of the individual rabbit. The mean scores for erythema and oedema formation in 3 rabbits used were subsequently calculated. - Irritation parameter:

- The primary skin irritant effect of Ukanol DOP was investigated according to the method recommended in the OECD Guideline No. 404, “Acute Dermal Irritation/Corrosion”, 1992, and EEC Guideline B.4 “Acute Toxicity (Skin Irritation)”, 29.12.1992. Three female albino rabbits were exposed to the test article at two skin sites on the back. After 4 hours of exposure the test article was removed and the skin was examined 1, 24, 48 and 72 hours after termination of exposure. No skin reactions were observed among the rabbits at any of the readings. Under the experimental conditions described in this report, the mean score for erythema was 0.0 and for oedema 0.0.

- Testing procedure:
The day before testing both eyes of the animals were examined with a hand held inspection lamp fitted with white and UV-light and magnifying glass with 2 x magnification to ensure there were no defects or irritation. The examination was performed before and after instillation of Fluorescein. Only the left eye was treated. The right eye remained untreated and served as control.
0.1 ml of the test article was placed in the left eye of the rabbits by gently pulling the lower lid away from the eyeball to form a cup into which the article was dropped. The lids were then gently held together for 1 second. The eyes were examined and the grade of ocular reaction was recorded 1 and 24 hours later. After the first 24 hour reading Fluorescein was instilled. After rinsing with 20 ml 0.9% sodium chloride solution the eyes were examined again using UV-light to detect possible corneal damage. The eyes were also examined 48 and 72 hours as well as 7 days after the treatment. The reactions were scored according to the grades for ocular lesions outlined in the attached report. - Irritation parameter:

- Executive summary:
The eye irritant effect of Ukanol DOP was investigated according to the method recommended in the OECD Guideline No. 405, “Acute Eye Irritation/Corrosion”, Feb. 1987, and EEC Guideline B.5 “Acute Toxicity (Eye Irritation)”, 29.12.1992.
Three female albino rabbits were exposed to 0.1 ml of the test article in the left eye. The eyes were examined and the changes were graded according to a numerical scale 1, 24, 48 and 72 hours as well as 7 days after dosing.
Moderate signs of eye irritation were observed among the rabbits.
The following mean values, based on the results from the 24, 48 and 72 hour readings, were calculated:
Ukanol DOP
cornea opacity 0.8
iris lesion 0.0
redness of conjunctiva 2.0
oedema of conjunctiva (chemosis) 1.1
Reference
The individual results are shown in Table 1 of attached report.
- One hour after application of the test article all three rabbits showed diffuse redness of conjunctivae and discharge with moistening of lids and hairs and considerable area around the eye.
- After 24 hours animal No. 1002 showed slight opacity of cornea on less than the half of the area. With Fluorescein all animals showed slight opacity of cornea on less than the half of the area. Diffuse redness of conjunctivae and discharge with moistening of lids and hairs and considerable area around the eye were observed in all animals. Slight swelling of conjunctivae was observed in animal Nos. 1000 and 1002, whereas animal No. 1004 showed obvious swelling of conjunctivae.
- After 48 hours all animals showed slight opacity of cornea on less than the half of the area. With Fluorescein all animals showed slight opacity of cornea on less than a quarter of the area. Diffuse redness and slight swelling of conjunctivae were observed in all animals. Animal Nos. 1000 and 1002 showed discharge with moistening of lids and hairs and considerable area around the eye, animal No. 1004 showed discharge of lids and hairs just adjacent to lids.
- After 72 hours animal No. 1000 showed slight opacity of cornea on less than the half of the area. With Fluorescein all animals showed no comeal reactions. Furthermore all animals showed diffuse redness and slight swelling of conjunctivae as well as discharge of lids and hairs just adjacent to lids.
- After 7 days no eye reactions due to the application of the test article were seen.
The following mean values were obtained from the data presented in Table 1 of attached report:
cornea opacity 0.8
iris lesion 0.0
redness of conjunctiva 2.0
oedema of conjunctiva (chemosis) 1.1Endpoint conclusion
- Endpoint conclusion:
