- physiological saline
- Concentration / amount:
- 10 %
- Day(s)/duration:
- 21
- Adequacy of challenge:
- highest non-irritant concentration
- No. of animals per dose:
- According to the test guidelines cited under "Introduction" the test was started with the minimum number of animals (5 per sex for the test group and 5 of one sex for controls). After the challenge procedure, it was not possible to conclude if the test substance is a sensitiser or not and therefore testing in additional animals was performed to give a total of 20 test and 10 control animals.
- Details on study design:
- Test procedure and concentrations used:
*Pretests (Intradermal Induction)
The concentration for the intradermal injections was selected on account of the solubility of the test article in standard vehicles and its local and systemic tolerability in a pretest. The following concentration of test article has been used for intradermal injection:
5 % in physiological saline (w/v).
Since 5 % FAT 21030/D in physiological saline could be injected and was well tolerated, this concentration was used for the intradermal induction.
*Pretest (Epidermal Applications (induction and challenge):
The concentrations for the epidermal applications were selected on account of the primary irritation potential of the test article. The following concentrations of FAT 21030/D have been examined on separate animals for the determination of the maximum subirritant concentration:
- 10, 20, 30, and 50 % in physiological saline.
- 50 % was the highest possible concentration of the test article in physiological saline.
Reactions were observed with 20, 30, and 50 % FAT 21030/D in physiological saline.
*Test procedure (Induction, intraderma injection):
- DAY 0: Three pairs of intradermal injections (0.1 ml per injection) were made simultaneously into the left and right side of the shaved neck of the test and control group animals.
Test group:
- adjuvant/saline mixture 1:1 (v/v)
- 5% FAT 21030/D in physiological saline (w/v)
- 5% FAT 21030/D in the adjuvant/saline mixture (w/v)
Control group:
- adjuvant/saline mixture 1:1 (v/v)
- adjuvant/saline mixture 1:1 (v/v)
- physiological saline
DAY 8: INDUCTION, epidermal application
In the test group FAT 21030/D was incorporated in physiological saline and applied on a filterpaper patch to the neck of the animals; (occluded
administration for 48 hours). The control group was treated with the vehicle only.
Test group:
- 50% FAT 21030/D in physiological saline
Control group:
- physiological saline only
DAY 21: Challenge
The test and control group animals were tested on one flank with FAT 21030/D in physiological saline and on the other flank with the vehicle alone (occluded administration for 24 hours).
Test and control group:
- 10% FAT 21030/D in physiological saline
- physiological saline only
Adjuvant: Bacto adjuvant, Complete, Freund (Difco Lab. Detroit, Michigan USA)
Physiological saline (0.9%), sterile solution (Hausmann, St Gallen, Switzerland) - Positive control substance(s):

- Remarks:
- 2-Mercaptobenzothiazole puriss. (Intradermal induction: 5 %, epidermal induction: 50 % and Epidermal challenge: 30 %)

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- FAT 21030/D is not a skin sensitiser.
- Executive summary:
FAT 21030/D was tested for skin sensitisation potential in albino guinea pigs using the maximisation test. This test was performed according to the OECD Guideline No 406 (GLP). Based on the findings of the pre-study, the 5, 50 and 10 % test concentrations were used for intradermal induction (day 0), epidermal induction (day 8) and epidermal challenge (day 21), respectively. 1/20 animals showed a positive reaction in the treated group, while no positive reactions were found in the control group. Hence, under experimental conditions employed, 5 % of the animals of the test group showed skin reactions 24 and 48 hours after removing the dressing. Hence, FAT 21030/D can be considered to be not a skin sensitiser.
