MAIN STUDY
A. INDUCTION EXPOSURE
Intradermal application
- No. of exposures: 1
- Test groups:
Three pairs of intradermal injections of 0.1 ml volume were given in the shoulder region so that one of each pair lies on each side of the midline.
Injection 1 (cranial): a 1:1 mixture (v/v) FCA/ physiological saline
Injection 2 (medial): 5% suspension of the test material in physiological saline
Injection 3 (caudal): 5% suspension of the test material formulated in a 1:1 mixture (v/v) FCA/ physiological saline.
- Control group:
Three pairs of intradermal injections of 0.1 ml volume were given in the shoulder region so that one of each pair lies on each side of the midline.
Injection 1 (cranial): a 1:1 mixture (v/v) FCA/ physiological saline
Injection 2 (medial): physiological saline
Injection 3 (caudal): physiological saline in a 1:1 mixture (v/v) FCA/ physiological saline.
- Frequency of applications: 1
Epicutaneous application
- No. of exposures: 1
- Exposure period: 48 h
One day before exposure, the application sides have been clipped and painted with 0.5 mL of 10% sodium lauryl sulphate in parafine oil . A hypoallergenic band-aid (2x4 cm) impregnated with 0.5 ml the test suspension (50 % test material in physiological saline (test group) or physiological saline (control)) was put on the injection sides of the intradermal application, covered with aluminium foil and fixed for 48 h using a Fermoflex tape (Transatlantic GmbH, Schwarzenbach). At the end of the exposure period the substance was removed using physiological saline.
B. CHALLENGE EXPOSURE
- No. of exposures: 1
- Day(s) of challenge: 21 days after intradermal induction
- Exposure period: 24 h
One day before exposure, the application sides have been clipped. Two hypoallergenic band-aids (2x4 cm) impregnated with 0.5 ml the test suspension (50 % test material in physioloigical saline) was applied to the left flank of all animals (test and control group) and fixed for 24 h using a Fermoflex tape (Transatlantic GmbH, Schwarzenbach). A control band-aids impregnated with 0.5 mL physiological saline was applied to right flank of each animal in the same manor. At the end of the application sides have been chemically depilated using Pilca-Crème (Olivin GmbH, Hamburg).
- Concentration: 50 %
- Evaluation (hr after challenge): 48 and 72 h
- Scoring: The skin reaction have been scored according to Draize.
OTHER:
The body weight of all animals was recorded one day before study inition and on the las day of the study. - Challenge controls:
- 10 animals previously treated with the vehicle were challenged together with the test group using the same test article concentration as used for the test group.
- Positive control substance(s):
- no

Results of the main test
Clinical observations:
No clinical signs were
observed in any animal during the study, but 2 and 3 days following the
2. induction all animals of the test group had red-coloured ears. One
animal of the test groups died on day 2. Necropsy revealed a blood
filled thorax and a pale liver. The body weight development of the
remaining animals corresponded to the control group.
The individual erythema and edema scores after the challenge are shown in Table 2.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In this study, conducted according to OECD 406, the test material can be considered as no dermal sensitiser.
- Executive summary:
In a dermal sensitization study conducted according to OECD 406 with a suspension of the test material in physiological saline, male guinea pigs were tested using the Guinea Pig Maximisation Test according to Magnusson and Kligman. Intradermal application was performed using a 5 % suspension of the test material. Epicutaneous induction was performed occlusive with a 50 % suspension for 48 h. The challenge was conducted with a 50 % suspensions of the test material for 24 h 21 days after the intradermal induction. Skin reaction was scored according to Draize. The application sides have been examined 48 and 72 h following application. No clinical sign or sign of sensitisation ware observed throughout the study, but the ears of all test group animals were coloured red 2 and 3 days after the epicutaneous application. One animal died on day two of the study. The body weight of the remaining animals developed correspondingly to the control group. Based on the results obtained in this study, the test material can be considered as not dermal sensitising.
