- 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.

- No. of exposures: 2 intradermal injections per animal
- Test groups: 5% test substance in dionized water or in 50% Freund's Adjuvant
- Control group: 50% Freund's Adjuvant
- Site: within a dorsal area of 2 x 4 cm
- Concentrations: 5% test substance
A2. DERMAL INDUCTION EXPOSURE
- Exposure period: 48 h
- Test groups: 25.0 % test substance in deionized water
- Control group: deionized water
- Site: The cellulose patch including the test substance covered the area where the intradermal injection had been placed
- Concentrations: 25.0 % test substance
B. CHALLENGE EXPOSURE
- Exposure period: 24h
- Test groups: 25.0 % test substance
- Site: One area of approx. 5 x 5 cm on the left flank, shaved mechanically
- Concentrations: 25.0 % test substance
- Evaluation (hr after challenge): 24h - Positive control substance(s):
- yes
- Remarks:
- benzocaine
Results and discussion
- Positive control results:
- Testing for sensitizing properties of Benzocain was performed in female Guinea pigs according to the method of MAGNUSSON & KLIGMAN.
Intradermal induction was performed using 1.0 % Benzocain in sesame oil. Dermal induction and challenge treatment were carried out with 25.0 % Benzocain in sesame oil.
Based on the results of this study Benzocain may cause sensitization by skin contact.

Any other information on results incl. tables
Maximum concentration not causing irritating effects in preliminary test: 25 %
Signs of irritation during induction:
The intradermal inductions of FCA (with and without test substance) lead to moderate edema and erythema, and further to callus and incrustations. During the dermal induction the areas pre-treated with FCA showed severe erythema and edema after 10 days. The skin areas treated only with the test substance showed no signs of irritation.
Evidence of sensitisation of each challenge concentration:
Treated group:0/10
Control group:0/5
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Reactive Navy FC63805 is not a dermal sensitizer based on results from a guinea pig maximization test.
- Executive summary:
In a dermal sensitization study with Reactive Navy FC63805 in dionized water or in 50% Freund's Adjuvant, 10 female Pirbright-White guinea pigs were tested using the guinea pig maximization test (GPMT). Under the conditions of the present study, none of ten animals of the treatment group showed a positive skin response after the challenge procedure.
