Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The LD0 of Reactive Red FC 73270 for male and female Sprague Dawley rats is >2000mg/kg body weight.
- Executive summary:
In an acute dermal toxicity study according to OECD 402, HSD Sprague Dawley rats, 5/sex, were dermally exposed to the test substance 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.
The acute dermal toxicity testing in the rat yielded a median lethal dose above 2000 mg/kg body weight in both male and female animals.
After administration of 2000 mg/kg bw neither deaths nor symptoms occurred. The skin surface of the animals was large discoloured red from staining with the test substance. This discolouration had not disappeared up to the end of the study in three animals.
Body weight was above the initial weight during the whole observation period.
The animals killed at the end of the observation period showed no macroscopically visible changes.
Dermal LD0 and LD50:
Males >2000 mg/kg body weight
Females >2000 mg/kg body weight
Combined >2000 mg/kg body weight
Reactive Red FC 73270 is of low toxicity based on LD0 > 2000 mg/kg body weight.
