- Details on study design:
- TYPE OF TEST(S) USED: repeated insult patch test (epicutaneous test)
ADMINISTRATION
- Type of application: occlusive
- Description of patch: 3.63 cm^2 patch, no further details provided
- Vehicle / solvent: Alcohol SD3A:DEP (25:75)
- Concentrations: 5%
- Volume applied: 0.2 mL
- Testing/scoring schedule: patches were applied to the skin with direct skin contact for 24 hours. Patches were applied to the same site on Monday, Wednesday and Friday for a total of 9 applications. Scoring was done 24 hours after removal of the patches by the subjects on Tuesday and Thursday and 48 hours after removal of the patches on Saturday.
The testing and scoring schedule may have been modified based on availability of the subjects.
- Removal of test substance: not specified
Challenge phase: following a 2-week rest period, the challenge patches were applied to previously untreated test site on the back. After 24 hours, the patches were removed and the test sites were evaluated for dermal reactions. The test sites were re-evaluated at 48 and 72 hours.

Applicant's summary and conclusion
- Conclusions:
- Application of 0.2 mL with 5% test substance applied at 3.63 cm^2 was not sensitising under the conditions of the test in 104 subjects.
- Executive summary:
The induction phase took place on Monday, Wednesday and Friday till 9 applications had been made in approximately 3 weeks. The amount of volume applied was 0.2 ml, test concentration used was 5% and the applied surface was 3.63 cm^2.
During the induction patches were placed at the upper side of the back. Technicians removed the patches 24 hours after application, except for Saturdays on which the patients removed the patches themselves. After removal, 24 hours the skin was not treated, except for the 48 hours treatment free period after the Friday application. Two weeks after the final induction treatment, a challenge patch was applied to untreated sites of the back and removed after 24 hours. Reactions to the challenge were assessed after 24, 48, 72 and 96 hours. None of the 104 subjects tested was sensitised by the sample. It was therefore concluded that the test substance is not sensitising at the concentration used.
