Details on test animals or test system and environmental conditions:
Age of aniamls at study initiation: AdultWeight at study initiation: 2.0 -3.5 kgAcclimation period: At least 7 days Environmental controls for the animal room was set to maintain a temperature of 70 deg F ±3 deg F, a relative humidity of 50% ±20%, and a 12-hour light/12-hour dark cycle.

Test system

Type of coverage:
occlusive
Preparation of test site:
abraded
Vehicle:
unchanged (no vehicle)
Controls:
no
Amount / concentration applied:
0,5 mL
Duration of treatment / exposure:
24 h exposure
Observation period:
72 h
Number of animals:
3 male and 3 female
Details on study design:
Test material was applied to two shaved test sites on each animal. Just before the test material was applied, crisscross epidermal abrasion were made on one of the exposed areas on each rabbit. The abrasions penetrated stratum corneum but they were not deep enough to penetrate the dermal layer and cause bleeding. Each treated area was covered with a gauze patch for 24 hours. The test site was washed with water after the 24h exposure period. Erythema and oedema was scored according to the Draize technique 30 minutes after the removal of the test material (24h). This was followed by a second reading after 72h

Applicant's summary and conclusion

Interpretation of results:
GHS criteria not met
Conclusions:
The primary dermal irritation of Imagent GI (PFOB) to the skin of rabbits was evaluated. The material produced no erythema or edema reactions. The primary dermal irritation index (the sum of the 24- and 72-hour scores divided by two) was determined to be 0.0, meaning that the material is not a primary skin irritant when tested by this method.
