- Housing: in transparent macrolon cages (type III) on soft wood granulate in an air-conditioned room, 1 animal per cage
- Diet (e.g. ad libitum): ssniff R/M-H (V 1534), ad libitum
- Water (e.g. ad libitum): tap water in plastic bottles, ad libitum
- Acclimation period: at least five days

ENVIRONMENTAL CONDITIONS

Administration / exposure

Type of coverage:

occlusive

Vehicle:

water

Details on dermal exposure:

TEST SITE
- Area of exposure: approximately 30 cm²
- Type of wrap if used: The appropriate amount of the test substance was moistened on a two-ply gauze and an aluminum foil (6 x 8 cm) and distributed as uniformly as possible. Together with the foil the test substance was administered to the shaved and intact dorsal skin. The foil was held in place with an elastic plaster bandage fixed around the animal's body.

REMOVAL OF TEST SUBSTANCE
- Washing (if done): washed with warm water
- Time after start of exposure: 24 h

TEST MATERIAL
- Concentration (if solution): 0.5 g Reaktiv Oliv F00-0149 was moistened with 0.3 mL deionized water.

Duration of exposure:

24 h

Doses:

2000 mg/kg bw

No. of animals per sex per dose:

5

Control animals:

no

Details on study design:

- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Symptoms were recorded twice every day (in the morning and in the afternoon), on weekends and public holidays only once. During this time the animals were weighed weekly.
- Necropsy of survivors performed: yes

Applicant's summary and conclusion

Interpretation of results:

not classified

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

The median LD50 (dermal) of Reactive Olive F00-0149 for male and female rats is >2000 mg/kg body weight.

Executive summary:

In an acute dermal toxicity study, HSD Sprague Dawley rats, 5/sex, were dermally exposed to Reactive Olive F00-0149 in deionized water for 24 hours to 30 cm² of body surface area at a dose of 2000 mg/kg body weight. Animals then were observed for 14 days.

Dermal LD50:

Males = >2000 mg/kg body weight

Females = >2000 mg/kg body weight

Combined = >2000 mg/kg body weight

Reactive Olive F00-0149 is of LOW Toxicity based on LD50 > 2000 mg/kg body weight.
