- RANGE FINDING TESTS:
Sites are prepared by clipping the hair on the day before application of the test article. An appropriate volume of test article is applied into the selected patch system. The animal is placed into the restrainer and the patches applied to the clipped skin surface. The patches are occluded with a rubber dental dam pulled taut and fastened to the bottom m of the restrainer with clips. The restrainer is adjusted to minimise movement of the animal during exposure. 6 hours later the dental dam and patches are removed and the animal is removed from the restrainer and replaced in its cage. Excess material may be removed. On the day following exposure, the animals are depilated and scored.

- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Following primary challenge there were no grades of 1 produced in the test or control animals. The incidence of grade ± responses in the test group, was compared to that of the naive control group. The incidence and severity of these responses in the test group were essentially comparable to those produced by the naive control group and this indicated that sensitisation had not been induced. Therefore no classification is warranted for sensitisation.
- Executive summary:
In a study conducted by Kreuzmann (1988), Guinea pigs were induced by applying patches of 75% (w/v) of the test substance, Busan 11-M1, to clipped exposure sites on the left shoulders of the animals. The 6 hour exposures were carried out weekly for 3 weeks. Two weeks later patches of the test substance were applied in the same manner for an exposure period of 6 hours to the test group and a naive control group at a concentration of 75% (w/v) of Busan 11-M1. At the test concentration used in this study, the test substance did not elicit allergenic responses and as such, is not considered to be a potential skin sensitiser. Based on these results, the test substance does not warrant classification for skin sensitisation in accordance with Regulation EC No. 1272/2008.

Migrated from Short description of key information:
Skin sensitisation (Adaptation of the method of Ritz and Buehler), guinea pig (Hartley) m/f (EPA OPP 81-6, GLP)
Justification for selection of skin sensitisation endpoint:
Only one study available for this endpoint
Respiratory sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
The test material did not induce skin sensitisation. Therefore no classification is warranted for skin sensitisation according the CLP Regulation.
