MAIN STUDY
A. INDUCTION EXPOSURE
CHROLOGICAL DESCRIPTION OF THE TEST PROCEDURE
STUDY DAY TEST PROCEDURE
0 The body weight of the animals was determined.
The guinea pigs were shaved mechanically over a dorsal area of 4X 6 cm in the vicinity of the shoulders.
1 INTRADERMAL INDUCTION TREATMENT
Two intradermal injections per animal of the following preparations.
The injection site (1,2,3) were all within a dorsal area of 2x4 cm. The injection sites were left uncovered.
Treatment group:
site appl. vol conc. preparation
1 2x0.1 mL - 50 % Freund's Adjuvant
2 2x0.1 mL 5 % substance in deionized water
3 2x0.1 mL 5 % substance in 50 % Freund's Adjuvant
Control group:
site appl. vol conc preparation
1 2x0.1 mL - 50 % Freund's Adjuvant
2 2x0.1 mL 5 % deionized water
3 2x0.1 mL 5 % equal volume of deionized water and 50 % Freund's Adjuvant
2-7 The administration area was examined for local tolerance. Any systemic toxic effects were recorded.
8 DERMAL INDUCTION
An amount of 0.5 mL of the test substance preparation (treatment group) or the vehicle (control group) was administrated to 2x 4 cm cellulose patch. This patch covered the area where the intradermal injection had been placed. The administration area was then kept for 48 hours under an occlusive bandage with an impermeable film and elastic bandage.
Treatment group: 25 % test substance in deionized water.
Control group: deionized water.
10 Occlusive bandage removed, irritant effects recorded.
11-21 No treatment of control or treatment group.
Test animals kept under observation.
B. CHALLENGE EXPOSURE
22 An amount of 0.5 mL of the test substance preparation was administrated to a 2x2 cm cellulose patch. The administration area was then kept for24 hours under an occlusive bandage with an impermeable film and elastic bandage.
Treatment and control group (left flank)
25.0% Reaktiv-Orange DYPR 934 in deionized water.
23 Occlusive bandage removed. Any remnants of the test substance were carefully washed off with warm water.
24 Examination of the skin approx. 24 hr after removal of the patches.
25 Examination of the skin approx. 48 hr after removal of the patches. Body weight of the test animal determined.
29 Repeat dermal treatment
Treatment and control group (right flank)
25.0 % Reaktiv-Orange DYPR 934 in deionized water.
Handling analogous to the first challenge treatment
30 Occlusive bandage removed. Any remnants of the test substance were carefully washed off with warm water.
31 Examination of the skin approx. 24 hr after removal of the patches.
32 Examination of the skin approx. 48 hr after removal of the patches.
Body weight of the test animals determined.
- Evaluation (hr after challenge):
Erytheme and edema are major clinical indicators of an allergic reaction. The decisive criterion for evaluation of the sensitizing properties of a test substance is the number of sensitized test animals, not the intensity of the dermal reaction.
The substance is considered to be sensitizing if 30 % more of animals in the treatment group definitely showed a positive skin reaction and at the same time nor irritant effects have emerged in the control group. - Positive control substance(s):
- yes
- Remarks:
- The validity of the test system is confirmed by the periodically conducted positive control using cinnamic aldehyde (CAS No. 101-86-0) for Buehler-Test (report No.:98.1044; 1999-01-12; Hoechst Marion Roussel, Deutschland GmbH)

After a challenge treatment no animal of the treatment group showed a positive skin reaction during the observation period.
The intradermal injections with Freund's Ajuvant
(with and without test substance) caused severe erythema and eodema as
well as indurations and encrustations.
Dermal induction treatment:
After removal of the patches at day 10, severe erythema and
edema, indurated and encrusted skin as well as necrosis were
observed at the sites previously treatd with Freund's
Adjuvant.
The administration sites treated with the test substance
alone showed no signs of irritaion.
Evidence of sensitization of each challenge concentration:
Treatment group: 0/9
Control group: 0/5
Other observations:
One animal of the treatment group was found dead at
day 30 of the study.
No toxic signs were observed.
None of nine animals of the treatment group showed
signs of intoxication throughout the study.
Applicant's summary and conclusion
- Interpretation of results:
- not sensitising
- Remarks:
- Migrated information REAKTIV-ORANGE DYPR 934 showed no evidence of sensitizing properties. Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of the study, none of nine animals of the treatment group showed a positive skin response after the challenge procedure.
Thus the percentage of animals reacting positive is below the threshold of 30%. Based on the results of this study REAKTIV-ORANGE DYPR 934 showed no evidence of sensitizing properties. - Executive summary:
Testing for sensitizing properties of Reaktiv-Orange 934 DYPR was performed in (nulliparous and non-pregnant) female guinea pig according to the method of Mangusson & Kligman.
Based on the fact that, no signs of irritation occured after administration of the different test concentrations, a concentration of 25 % Reaktiv-Orange DYPR 934 in deionized water was chosen for dermal as well as for challenge induction.
A 5 % preparation was selected for the intradermal injections in the main test.
The Reliability check of the test system is confirmed by the periodically conducted positive control using cinnamic aldehyde (CAS No. 101-86-0) for Buehler-Test (report No.:98.1044; 1999-01-12; Hoechst Marion Roussel, Deutschland GmbH).

-0.5 mL of the test substance was administrated to a cellulose patch fixed on the flank and covered occlusively
-ENVIRONMENTAL CONDITIONS
- Temperature ( °C): 20+/- 3 °C
- Humidity (%): 50 +/- 20 %
- Photoperiod (hrs dark / hrs light): 12 hours daily
The validity of the test system is confirmed by the periodically conducted positive control using cinnamic aldehyde (CAS No. 101-86-0) for Buehler-Test (report No.:98.1044; 1999-01-12; Hoechst Marion Roussel, Deutschland GmbH)
Vehicle: deionized water
-No signs of irritation occurred after administration of different test concentrations.
-Body weight gain of the animals was not impaired.
-One animal of the treatment group was found dead at day 30 of the study. But this incident was not related to the substance.
