Details on dermal exposure:

TEST SITE
- Area of exposure: approximately 30 cm²
- Type of wrap if used: the test substance was moistened on a two-ply gauze and an aluminum foil (6 x 8 ern) and distributed as uniformly as possible. 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
- Amount(s) applied (volume or weight with unit): 0.5 g Reaktiv Rot F00-0124 was moistened with 0.4 mL deionized water
- Constant volume or concentration used: yes

Duration of exposure:

24 h

Doses:

2000 mg/kg body weight

No. of animals per sex per dose:

5/sex

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

Results and discussion

Sex:

male/female

Dose descriptor:

LD50

Effect level:

> 2 000 mg/kg bw

Based on:

test mat.

Mortality:

Male: 2000 mg/kg body weight; Number of animals: 5; Number of deaths: 0
Female: 2000 mg/kg body weight; Number of animals: 5; Number of deaths: 0

Clinical signs:

No symptoms were observed after administration of 2000 mg/kg body weight.

Body weight:

1 female animal showed a slight loss of body weight during the first week of the study, which returned to normal until the end of the study.
In all other animals development of body weight was not impaired.

Gross pathology:

No gross patholgoy changes

Other findings:

The skin of the animals showed violett discolorations from day 2 up to day 6 of the study.

Applicant's summary and conclusion

Interpretation of results:

not classified

Remarks:

Migrated information Criteria used for interpretation of results: EU

Conclusions:

The median LD50 of Reactive Red F00-0124 for male and female Sprague Dawley rats is > 2000 mg/kg body weight.

Executive summary:

In an acute dermal toxicity study, groups of Hsd Sprague Dawley rats, 5/sex, were dermally exposed to Reactive Red F00-0124 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 Red F00-0124 is of low Toxicity based on LD50 is >2000 mg/kg body weight.
