Administration / exposure

Route of administration:
oral: gavage
Vehicle:
other: 1,2-propanediol
Details on oral exposure:
VEHICLE
- Concentration in vehicle: 40g/ 100 ml
- Amount of vehicle (if gavage): 5 ml/kg bw
- Justification for choice of vehicle: Good homogeneity in 1, 2 Propanediol

MAXIMUM DOSE VOLUME APPLIED: 2000 mgkg bw, 5 ml/kg bw

CLASS METHOD (if applicable)
- Rationale for the selection of the starting dose: no acute toxicity expected

DOSAGE PREPARATION (if unusual): For better handling the test item was heated approx. 1 hour at 70°C. The preparations were administered handwarm.
Doses:
2000 mg/kg bw
No. of animals per sex per dose:
2 x 3
Control animals:
no
Details on study design:
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: recording of clinical sings several times on the day of administration, and at least once daily thereafter each workday for the individual animals, check for any dead or moribund animals was made at least once each workday, body weights shortly before administration (day 0), weekly thereafter and on the last day of observation
- Necropsy of survivors performed: yes
