The animals were marked by serial numbers 1 – 4. These numbers were placed in the cage and on the auricle. Husbandry:Housing: Animals were housed in cages individually. Diet: A standard certified laboratory diet (supplier Top Dovo Dobrá Voda) was served. The diet is routinely analysed by the manufacturer for nutritional components and environmental contaminants. Water: Ad libitum.Environment: Environmental control for the animal room was set to maintain 18 ± 3°C, a relative humidity of 40 – 70% a minimu of 10 air changes/hour, and a natural light regime. Acclimation: According SOP No 001/53204/07 Quarantine of animals.
- Type of coverage:

- Preparation of test site:
- clipped
- Vehicle:
- other: Olivae oleum raffinatum
- Controls:

- Amount / concentration applied:
- A dose of 0.5 g of Dusantox 86 was pulverised, moistened with the vehicle. Vehicle Article: Olivae oleum raffinatum, Certificate of analysis No 625/539/64/2007, Lot Number: L706203
- Duration of treatment / exposure:
- exposure period 4 hours.
- Observation period:
- 72 hours.
- Number of animals:
- 4 male rabbits.
- Details on study design:
- Preparation of dosesThe test article was pulverised and moistened sufficiently with olivae oleum shortly prior to administration. Test ProcedurePreparation of Test Area: Approximately 24h before the test, fur was removed from the test area by clipping from the dorsal area of the trunk of the animals. Only animal with healthy intact skin were used. Exposure of Animals: The study was begun with an initial test using one animal. The test article was applied to a small area (approximately 6 cm2) of skin and covered with a gauze patch. The patch was loosely held in contact with the skin by means of a suitable semi-occlusive dressing for the duration of the exposure period (4h). At the end of the exposure period, residual test preparation was removed using olivae oleum. Because a corrosive effect was not observed in initial test, the irritant response was confirmed using up to three additional animals simultaneously.Application of Test Article: The test article (0.5 g) was moistened sufficiently with olivae oleum and was applied to the skin and to the gauze patch.Observation of Animals: The appearance of skin reactions was observed and recorded at 1h, 24h, 48h and 72 h following removal of the patches. The skin reactions for erythema and oedema were described and graded according to the classification system for the application site at each time interval.

- Other effects:
- The well-defined erythema classified as grad 2 was observed as the worst skin reaction on the Dusantox 86 only in one animal. Skin reactions on other animals were determined as grad 1 – very slight erythema. No observation of erythema or oedema was noted on the vehicle application site. During 7 days after removal of patches erythema had disappeared in all animals. No oedema was occurred in the course of study.
- Interpretation of results:

- Executive summary:
The skin irritation potential of Dusantox 86 was tested in four albino rabbits. The test article was applied in a single dose to the clipped skin of experimental animals, each animal serving as its own control. A dose of 0.5 g of Dusantox 86 was pulverised, moistened with olivae oleum and applied to the intact skin of rabbits for 4 h under semi-occlusive dressings. The degree of irritation was read and scored at specified intervals (1 h, 24h, 48 h and 72h following removal of the patches) and was described to provide a complete evaluation of the effects. The Primary Irritation Index of Dusantox 86 for single exposure determined in this study was PII = 0.4. According to this value the test article belongs to response category “Negligible”.
No classification and labelling is applicable.

- TEST PERFORMANCEBefore the study animals were quarantined for 20 days in the conditions identical to the conditions during the experiment. Both eyes of the rabbits were examined within 24 hours before beginning of the test. Test material was placed in amount of 100 mg of Dusantox 86 in the conjunctival sac of rabbit’s right eye. The left eye was served as control. The eyes in all rabbits were examined and score for signs of irritation in the cornea, iris and conjunctiva at 1, 24, 48 and 72 hours after test substance application. Examination of reactions were facilitated by used of hand lamp and magnifying glass. Application of the test articleDusantox 86 (100 mg) was pulverized, moistened sufficiently with olivae oleum raffinatum and apply to right eye.

Additional information
Skin Irritation
The skin irritation potential of Dusantox 86 was tested in four albino rabbits. The test article was applied in a single dose to the clipped skin of experimental animals, each animal serving as its own control. A dose of 0.5 g of Dusantox 86 was pulverised, moistened with olivae oleum and applied to the intact skin of rabbits for 4 h under semi-occlusive dressings. The degree of irritation was read and scored at specified intervals (1 h, 24h, 48 h and 72h following removal of the patches) and was described to provide a complete evaluation of the effects. The Primary Irritation Index of Dusantox 86 for single exposure determined in this study was PII = 0.4. According to this value the test article belongs to response category “Negligible”.
No classification and labelling is applicable.
Eye Irritation
The test article was applied in a single does to right eye of the rabbits. The left eye was used as the control. The degree of eye irritation was evaluated scoring lesions of conjunctiva, cornea, iris and lids at 1, 24, 48 and 72 hours after application. Dusantox 86 had not apparent corrosive or irritation effect on rabbits eyes. No classification and labelling is applicable.
Justification for selection of skin irritation / corrosion endpoint:
Study performed to OECD guideline 404.
Justification for selection of eye irritation endpoint:
Study performed to OECD guideline 405.
Justification for classification or non-classification
The above studies have all been ranked reliability 1 according to the Klimisch et al system. This ranking was deemed appropriate because the studies were conducted to GLP and in accordance with appropriate OECD Guideline. Sufficient dose ranges and numbers are detailed; hence it is appropriate for use based on reliability and animal welfare grounds.
The above results triggered no classification under the CLP Regulation (EC No 1272/2008). No classification for acute effects is therefore required.
