- RANGE FINDING TESTS:
Intradermal – Four guinea pigs were injected intradermally at dorsal skin with 0.1 mL of test substance suspended in physiological saline (3, 1, 0.5, 0.3, 0.1, 0.05, 0.01 and 0.005%). Skin reaction was observed 24, 48 and 72 hours later. In the results, blackish change, ulcer or necrosis of skin was noted at 0.05% and more. In addition, moderate erythema was noted between 0.01 and 0.005%. From these results, 0.01% was selected for main study sensitising concentration.
Dorsal skin was applied with a 1.5 x 1.5 cm square lint, which was impregnated with 0.06mL of test substance suspended in physiological saline (10, 5, 3, 1 and 0.5%) or test substance dissolved in 50% ethanol, by closed patch method same as induction exposure and observed reaction. In the results, very slight erythema was noted at 1% and more in physiological saline suspension and at 10% in 50% ethanol solution. On the other hand, there were no signs of erythema or edema at 0.5% in physiological saline suspension. From these results, for the main study, water for injection was selected as vehicle, 10% was selected as induction concentration and 0.5, 0.3, 0.1, 0.05, 0.03 and 0.01% were selected as challenge concentration.
INTRADERMAL INDUCTION
On the day before intra-dermal induction (induction -1 day), intradermal induction area of neck
dorsal skin (Figure, broken line) and its surrounding were shaved and clipped with an electric shaver and electric clipper. On next day (induction 0 day), 2 areas of (1, (2) and (3) shown in the figure were injected intradermally with 0.1 mL/area of follows.
Area (1) in all groups was injected with FCA emulsified liquid in physiological saline. Areas (2) and (3) in the test article group were injected with 0.01% of the test substance suspended in physiological saline and 0.01% FCA emulsified liquid, respectively. Areas (2) and (3) in the vehicle control group were injected physiological saline and FCA emulsified liquid in physiological saline, respectively.
PATCH INDUCTION
On induction 6 day, patch induction area (Figure, broken line) and its surrounding were shaved
and clipped with an electric shaver and electric clipper.
On induction 7 day, patch induction area was applied with square lint (size of 2 X 4cm), which was impregnated with 0.2 mL of follows. In the test article group, 10% of the test substance suspended in physiological saline was used. In the vehicle control group, water for injection was used. The lint was covered with a dental damp-proof rubber sheet and fixed by swaddling with an adhesive elastic bandage. The dressing was left for 48 hours.
CHALLENGE
On induction 20 day, dorsal skin was shaved and clipped with an electric shaver and electric
clipper. On next day (induction 21 day), in both test article and vehicle control group, dorsal
challenge area (Figure, solid line) was applied a 1.5 X 1.5cm square lint, which was impregnated with 0.06 mL of the test substance suspended in physiological saline (0.5, 0.3, 0.1, 0.05, 0.03 and 0.01 %). The lint was covered with a dental damp-proof rubber sheet and fixed by swaddling with an adhesive elastic bandage. The dressing was left for 24 hours. To avoid deviation of the skin reaction, the challenge sites were rotated among the animals.
OBSERVATIONS AND JUDGEMENTS
Skin reaction was observed 24, 48 and 72 hours later from removing test article and scored
according to the criteria in Table 2 in 'any other information on materials and methods incl. tables'. The mean score of each group at each time point (sum of the total score of the reaction in each group/number of animals in each group) were calculated. In addition, all animals were photographed. - Challenge controls:
- Conditions for test group and control group are identical (0.5, 0.3, 0.1, 0.05, 0.03 and 0.01%. as suspension in water).

Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information
- Conclusions:
- There was no evidence of reactions indicative of skin sensitisation to the notified chemical under the conditions of the test. The test material does not meet the criteria for classification according to EU classification system.
- Executive summary:
From these results of preliminary study,
water for injection as vehicle, 10% as induction concentration and 0.5, 0.3, 0.1, 0.05, 0.03 and 0.01% as challenge concentration were selected for the main study.There were no signs of erythema or oedema at each challenge area in both test article and vehicle control groups.
