Administration / exposure
- Route of administration:
- oral: gavage
- Vehicle:
- unchanged (no vehicle)
- Details on oral exposure:
- CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: When the information suggests that mortality is unlikely at the highest dose level (2000 mg/kg body weight), then a limit test should be conducted. An initial dose of 2,000 mg/kg may be administered to three animals, in a step-wise method if necessary.
Dose Administration:
Individual dose volume was adjusted according to body weight, dose level and specific gravity of the test item. All rats were dosed by oral gavage (day 1) using a metal cannula attached to a BD 1 mL disposable syringe which was graduated up to 1 mL. Rats were fasted overnight prior to dosing until three hours post-dosing.
Limit Study:
Three female rats from set 1 were given a single dose of 2000 mg C.I. Solvent Red 175/kg body weight. As no mortality was observed up to approximately 48 hours at this dose level, another three female rats from set 2 were administered with the same dose of 2000 mg C.I. Solvent Red 175/kg body weight. As no mortality was observed at this dose level, further testing was not required. - Doses:
- 2000 mg/kg body weight
- No. of animals per sex per dose:
- 6 females
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: The rats were observed for signs of toxicity and mortality at ½, 1, 2, 3, 4 and 6 hours postadministration on the day of dosing. Subsequently, they were observed twice a day for morbidity and mortality for a period of 14 days following oral dosing. The clinical signs were recorded once a day. Individual body weights were recorded prior to dosing on day 1, and on days 8 and 15.
- Necropsy of survivors performed: yes
- Other examinations performed: A gross pathological examination at necropsy consisting of an external examination and opening of abdominal and thoracic cavities was performed. The stomach of each rat was opened, the contents rinsed/removed, and the mucosal surface was examined for signs of irritation, erosions, ulcers or any other findings. Gross macroscopic changes, if any, were recorded.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- No mortality was observed in the treated rats. Rats treated with the C.I. Solvent Red 175 at 2000 mg/kg body weight showed no signs of toxicity. The acute oral LD50 of the C.I. Solvent Red 175 was estimated to be greater than 2000 mg/kg body weight in female Wistar rats.
- Executive summary:
An acute oral toxicity study (Acute Toxic Class Method) was conducted using female Wistar rats given a single oral dose of C.I. Solvent Red 175 (undiluted, as received). A Limit Test was conducted with 2000 mg/kg body weight. The first set of three rats survived; hence an additional set of three female Wistar rats each received a single dose of 2000 mg/kg body weight according to the Acute Toxic Class Method. No mortality was observed in the treated rats. Rats treated with the C.I. Solvent Red 175 at 2000 mg/kg body weight showed no signs of toxicity. All animals were active and healthy and gained body weight during the course of the study.
External and visceral examination of terminally sacrificed rats did not reveal any pathological lesions in any of the treated animals. The acute oral LD50 of the C.I. Solvent Red 175 was estimated to be greater than 2000 mg/kg body weight in female Wistar rats.
