- other: fur was removed with electric clippers
- Vehicle:
- water
- Remarks:
- moistened sufficiently with aqua ad injectabilia to ensure good contact with the skin
- Controls:
- other: an adjacent area of untreated skin served as control
- Amount / concentration applied:
- 0.5 g on about 6 cm² in size
- Duration of treatment / exposure:
- 4 h
- Observation period:
- 30-60 min, 24, 48 and 72 h after patch removal.
- Number of animals:
- 3
- Details on study design:
- TEST SITE
- Area of exposure: roughly 8 x 15 cm on the back of each animal
- % coverage:
- Type of wrap if used: each test area was covered with a semi-occlusive dressing consisting of Ypsiplast® (Holthaus Medical, Remscheid-Lüttringhausen), which was held in place by non-irritating tape Elastoplast® (Beiersdorf AG, Hamburg), and Stülpa® (P. Hartmann AG, Heidenheim-Brenz), which enveloped the whole of the animal's trunk.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): At the end of the 4-h exposure period, the dressing was removed and any residual sample was carefully washed off with water or an appropriate solvent.
- Time after start of exposure: 4 hours
24 h before treatment, fur was removed with electric clippers from an area of roughly 8 x 15 cm on the back of each animal. The skin was examined for abrasions and only animals with healthy, intact skin were used in the test.
The solid test article was moistened sufficiently with Aqua ad injectabilia to ensure a good contact with the skin.
In each animal, 0.5 g of the test article were applied to the test site (ca. 6 cm² in size), an adjacent area of untreated skin serving as a control.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: other: EU-GHS
- Conclusions:
- The study was performed according to the OECD Guideline 404 with no deviations and according to the good laboratory practice principles, it is considered to be of the highest quality (reliability Klimisch 1). The criteria of validity of the test system are fulfilled. The mean grades of skin reactions at 24, 48 and 72 h after patch removal were lower than the value classified as irritant by the European regulation (EC) No. 1272/2008, amending regulation EC no. 1907/2006 (REACh). When applied to the skin, the test article may therefore be considered to be non-irritant. The test material did not induce irritation on the intact skin of rabbits. The product bis(2.6-diisopropylphenyl)carbodiimide is considered to be not irritating to the skin.
- Executive summary:
The skin irritation potential of the test substance was investigated in rabbits (Kaufmann, 1993, according to TG OECD 404). Bis(2.6-diisopropylphenyl)carbodiimide was applied to the skin of rabbit (skin prepared with electric clippers, 0.5 mg pure substance moistened with water) for 4 hours under semiocclusive conditions. The study was performed according to the OECD Guideline 404 with no deviations and according to the good laboratory practice principles, it is considered to be of the highest quality (reliability Klimisch 1). The criteria of validity of the test system are fulfilled. After this period the skin was evaluated 30- 60 min, 24, 48 and 72 h after patch removal. No test article- dependent findings were observed. The mean grades of skin reactions were lower than the value classified as irritant by the European regulation (EC) No. 1272/2008, amending regulation EC no. 1907/2006 (REACh). When applied to the skin, the test article may therefore be considered to be non- irritant.
