Reference
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (sensitising)
- Additional information:
The test substance was tested for its sensitizing effect on the skin of the guinea pig in the Maximization Test based on the method of Magnusson and Kligman. After the intradermal induction well-defined erythema and slight edema were observed at the injection sites of the control group animals and test group animals at which only Freund's adjuvant/0.9%/ aqueous NaCl-solution (1 :1) was applied. Injection of the test substance preparation in olive oil DAB 9 also caused well-defined erythema and slight edema in the test group animals. After applicatian of the test substance preparation in Freund's adjuvant/ 0.9% aqueous NaCl-salution (1 :1) necrotic skin changes and slight edema could be observed in the animals of the test group. The control group animals injected with olive oil DAB 9 (vehicle) exhibited well-defined erythema. After the percutaneous induction, necrotic skin changes partially open (caused by the intradermal induction) in addition to slight edema could be observed in the test group animals. The animals of the control groups, which were treated with olive oil DAB 9 showed incrustation partially open (caused by the intradermal induction) in addition to well-defined erythema and slight edema.
Based on the results of the study it was concluded that the test substance has a sensitizing effect on the skin of the guinea pig in the Maximization Test.

Justification for classification or non-classification
Classification,
Labelling, and Packaging Regulation (EC) No 1272/2008
The available experimental test data are reliable and suitable for
classification purposes under Regulation (EC) No 1272/2008. As a result
the substance is considered to be classified for skin sensitisation into
category 1 (H317: may cause an allergic skin reaction) under Regulation
(EC) No 1272/2008, as amended for the sixth time in Regulation No
605/2014.
Dangerous
Substance Directive (67/548/EEC)
The available study is considered reliable and suitable for
classification purposes under 67/548/EEC. As a result the substance is
considered to be classified as R43 (May cause sensitisation by skin
contact) under Directive 67/548/EEC, as amended for the 31st time in
Directive 2009/2/EG.
