- Details on test animals and environmental conditions:
- Husbandry
Animal health: Only animals in acceptable health condition were used for the test. It is certified by the veterinarian
Cage type: Animals were housed in macrolon cages, size III, with 3 or 2 animals/cage ( 42 x 42 x 19 cm)
Bedding: laboratory bedding
Animal room: 614
Light: 12 hours daily from 6 a.m. to 6 p.m. (artificial light)
Temperature: 20 ±3°C
Relative humidity: 30-70%
Rate of air exchange: 13-17 hours
Food and Feeding
Animals received UNIPLUS standard diet for rabbits produced by AGRIBRANDS Europe Hungary, ad libitum.
Water Supply
The animals received tap water, as for human consumption, ad libitum containing 50 mg/100mL Ascorbic acid. - Route:
- intradermal and epicutaneous
- Vehicle:
- physiological saline
- Remarks:
- NaCl 0.9%
- Concentration / amount:
- Series of test item concentrations were tested to specify the primary irritation by intradermal injection and dermal application. Four dose levels were tested in the preliminary dose range finding study to specify the primary irritation by intradermal injection and four dose levels by dermal application.
The test item was applied in concentrations of 0.1, 1, 5, 10, 25, 50 and 75% (w/v).
For the intradermal application 0.1 mL formulated test item was injected in concentrations of 0.1, 1, 5 and 10% (w/v). Two different concentrations were applied
per animal to the hairless skin on the right and left flanks, and two animals were employed per concentration tested.
For the dermal application 0.5 mL formulated test item was applied onto the skin of the animals in concentrations of 10, 25, 50, 75% (w/v). A closed patch exposure was employed by means of an occlusive bandage. Two animals/ two different concentrations were used.
It was found that 0.5 mL of test formulation in concentrations of 10, 25 and 50% produced no reaction on the skin of guinea pigs. In concentration of 75% very slight and well defined erythema occurred one hour after the patch removal. - Route:

- Test group: 10 animals
Control group: 5 animals - Challenge controls:
- 24 hours before the challenge treatment the left and the right flank areas (5x5 cm) of each animal were prepared for application. The challenge was performed as a dermal exposure (Closed Patch Test).
Left shaved flank areas of the animals (both the test and the control) were treated with 0.50 ml of the test item (in concentration 50%). The right shaved flank areas were treated with 0.50 ml of distilled water, in all cases. Time of exposure was 24 hours. - Positive control substance(s):
- yes
- Positive control results:
- 5 control animals were exposed to vehicle during induction treatment and they were treated with the reference item on the challenge day only. No visible changes were found at the 241 h and 481 h hour examinations. During the challenge exposure, the reference item POTASSIUM DICHROMATE (in concentration of 0.3%) did not evoke primary irritation.
