- 2 RANGE FINDING TESTS:
3 males, 3 females: each animal is exposed to 4 different concentrations of the test material (1%, 10%, 25%, 100%): 80% ethanol as the vehicle.
1 male, 1 female: each animal is exposed to 4 different concentrations of the test material (50%, 60%, 70%, 80%): 80% ethanol as the vehicle
primary challenge responses were graded
Highest non-irritatting concentration = concentration in vehicle that induced responses not exceeding 2 "+" and 2 "0" grades in the group of 4 animals.
the dose chosen for induction: 70%,
the dose chosen for challenge: 40%
MAIN STUDY
A. INDUCTION EXPOSURE
- No. of exposures: 4 (3 inductions, 1challenge)
- Exposure period: -
- Test groups: test substance in vehicle (80% ethanol)
- Control group: vehicle only
- Site: L shoulder (first induction); R shoulder (second and third induction)
- Frequency of applications: once a week
- Duration: 6 h
- Concentrations: 70% (first induction); 40% (second and third induction)
B. CHALLENGE EXPOSURE
- No. of exposures: 1
- Day(s) of challenge: day 29
- Exposure period: -
- Test groups: test substance in vehicle
- Control group: vehicle only
- Site: naive site on left flank
- Concentrations: 40%
- Evaluation (hr after challenge): 24 and 48h
OTHER:
24h after challenge, all animals were depilated with Neet Cream Hair Remover (Whitehall Laboratories, Inc., New York). A minimum of 2h after depilation test sites were graded. The grading was repeated 24h later (48h grade). - Challenge controls:
- Four naive animals (2 males, 2 females) were induced with the test material (40% concentration) on challenge day in the same manner as the test group and control groups.
- Positive control substance(s):
- yes
- Remarks:
- 1-chloro-2,4-dinitrobenzene
Results and discussion
- Positive control results:
- Sensitising effects were observed in all six animals of the positive control group.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based upon the observations made in the assay, the test article induced at 70% (1st) and 40% (2nd and 3rd) and challenged at a 40% concentration, did not cause delayed contact hypersensitivity in guinea pigs.
