Test animals

Species:
rat
Strain:
Sprague-Dawley
Sex:
male/female

Administration / exposure

Route of administration:
oral: gavage
Vehicle:
unchanged (no vehicle)
Remarks:
none
Details on oral exposure:
The animals were dosed on 04Nov85 at a level of 5000 mg/kg. Each rat was dosed by drawing the specified volume into a 3cc syringe and orally intubating the restrained animal with a stainless steel gavage needle and introducing the test article into the stomach.
Doses:
5000 mg/kg
No. of animals per sex per dose:
5 male and 5 female
Control animals:
no
Details on study design:
Within 24 hours before dosing, each animal was weighed and observed for general health. The rats were randomly assigned to the test using a computer randomization program. All rats were fasted for approximately 16 hours before dosing.

The animals were dosed on 04Nov85at a level of 5000 mg/kg. Each rat was dosed by drawing the specified volume into a 3cc syringe and orally intubating the restrained animal with a stainless steel gavage needle and introducing the test article into the stomach.

Each animal was observed for the following: no observable abnormalities, oral discharge, nasal discharge, respiration, tremors, incoordination, recumbancy, and stools. The categories were on a 1 to 3 scoring scheme (slight, moderate, severe).
All animals were observed hourly for the first four hours the day of dosing and twice a day during the 14 -day observation period.

All animals at the conclusion of the study were subjected to a gross necropsy.

Applicant's summary and conclusion

Interpretation of results:
not classified
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The LD50 for F-64-01 in rats is >5000 mg/kg. Based on the parameters of this study, F-64-01 is not classified as an acute oral toxicant under Regulation (EC) 1272/2008 on classification, labeling, and packaging of substances and mixtures (CLP) or under the Directive 67/518/EEC for dangerous substances and Directive 1999/45/EC for preparations.
Executive summary:

The acute toxicity of F-64-01 was evaluated in rats via oral gavage at a dose of 5000 mg/kg fasted body weight. Observations were made hourly for the first 4 hours immediately after dosing and twice daily (a.m. and p.m.) for the next 14 days.  No animals died during the observational period. The LD50 for F-64-01 in rats is >5000 mg/kg. Based on the parameters of this study, F-64-01 is not classified as an acute oral toxicant under Regulation (EC) 1272/2008 on classification, labeling, and packaging of substances and mixtures (CLP) or under the Directive 67/518/EEC for dangerous substances and Directive 1999/45/EC for preparations.
