10 animals in the treatment group and 5 animals in the control group were used. In case of a questionable result additional animals will be tested to give a total of 20 test and 10 control animals. - Details on study design:
- RANGE FINDING TESTS:
- Determination of the primary non-irritant concentration:
Prior to the determination of the primary non-irritation concentration in a dermal occlusive test the animals received 4 intradermal injections of a 50% Freund's
Complete Adjuvant emulsion (4 x 0.1 ml) into the dorsal area. Two guinea pigs then received either 25%, 5%, or 1% test substance in dionized water. Flank hair was mechanically removed and 0.5 ml of the test substance preparation was administered to a 2 x 2 cm cellulose patch covered occlusive for 24 hours. 24 hours after removal of the patches, the treated skin areas were examined for erythema and edema.
- Determination of the tolerance of the intradermal injections:
To determine the tolerance of intradermal injections, 5%, 1%, or 0.2% of the test substance was administered twice by intradermal injection to 2 guinea pigs. 24, 48, 72 and 96 hours after administration the injection sites were examined for local tolerance.

Any other information on results incl. tables
Due to the red color of the test substance the treated skin of the animals could not be assessed for erythema 24 and 48 hours after removal of the occlusive bandage.
No significant difference in the fold thickness of the treated skin was detected between the animals of the control and of the treatment group.
In addition, no significant difference was found between the animals of the control and of the treatment group with respect to the histopathological evaluation of the treated skin area. The findings in both the control and the treatment group reveal a slight
reaction of the skin tissue indicating an irritant response to the occlusion of the skin.
Thus, neither measurement of the fold thickness nor histopathological examination of the treated skin showed any evidence for sensitizing properties of the test substance. No skin reactions were observed in the control group 24 and 48 hours after removal of the occlusive bandage.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Reactive Red FC73270 showed no evidence for sensitizing properties.
- Executive summary:
Testing for sensitizing properties of Reaktiv Rot FC-73270 was performed in female guinea pigs according to the method of MAGNUSSON & KLIGMAN. Intradermal induction was performed using 5 % Reaktiv Rot FC-73270 in deionized water. Dermal induction and challenge treatment were carried out with 25 % Reaktiv Rot FC-73270 in deionized water.
The validity of the test system is confirmed by the periodically conducted positive control test using benzocain for the maximization test.
Due to the red color of the test substance the treated skin of the animals could not be assessed for erythema. Based on both measurement of fold thickness and histopathological examination of the treated skin Reaktiv Rot FC-73270 showed no evidence for sensitizing properties.
