Administration / exposure
- Type of coverage:
- occlusive
- Vehicle:
- propylene glycol
- Details on dermal exposure:
- One day before exposure (Day -1) an area of approximately 5x7 cm on the back of the animal was clipped.
The formulation was applied in an area of approx. 10% of the total body surface, i.e. approx. 25 cm² for males and 18 cm² for females. The formulation was held in contact with the skin with a dressing, consisting of a surgical gauze patch, successively covered with aluminum foil and Coban elastic bandage. A piece of Micropore tape was additionally used for fixation of the bandages in females only.
Frequency: Single dosage, on Day 1.
Washing: Following application, dressings were removed and the skin cleaned of residual test substance using tap water. - Duration of exposure:
- 24 hours.
- Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 5
- Control animals:
- no
- Details on study design:
- VEHICLE
- Justification for choice of vehicle: The vehicle was selected based on trial formulations performed at NOTOX and on test substance data supplied by the sponsor.
Dose volume: 10 mL/kg bw.
DOSAGE PREPARATION: The formulation (w/w) was prepared within 4 hours prior to dosing. Homogeneity was accomplished to a visually acceptable level. Adjustment was made for specific gravity of the vehicle.
Duration of observation period following administration: 14 days
- Frequency of observations and weighing:
Mortality/Viability: Twice daily.
Body weights: Days 1 (pre-administration), 8 and 15.
Clinical signs: At periodic intervals on the day of dosing (Day 1) and once daily thereafter, until Day 15.
- Necropsy of survivors performed: At the end of the observation period, all animals were sacrificed by oxygen/carbon dioxide procedure and subjected to necropsy. Descriptions of all internal macroscopic abnormalities were recorded. - Statistics:
- None.
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No mortality occurred.
- Clinical signs:
- Chromodacryorrhoea was observed for one female on Day 1.
- Body weight:
- The changes noted in body weight gain in males and females were within the range expected for rats used in this type of study and were therefore considered not indicative of toxicity.
- Gross pathology:
- No abnormalities were found at macroscopic post mortem examination of the animals.
- Other findings:
- On the treated skin area, orange staining, scales and/or scabs were present among all animals during the observation period.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In an acute dermal toxicity study with rats, performed according to OECD/EC test guidelines, an LD50 >2000 mg/kg bw was determined.
- Executive summary:
An acute dermal toxicity study with rats was performed according to OECD/EC test guidelines. In the 5 male and 5 female rats treated, no mortality occurred. On the treated skin area, orange staining, scales and/or scabs were present among all animals during the observation period. Chromodacryorrhoea was observed for one female on Day 1. The changes noted in body weight gain in males and females were within the range expected for rats used in this type of study and were therefore considered not indicative of toxicity. No abnormalities were found at macroscopic post mortem examination of the animals.
Based on these data, the dermal LD50 value in Wistar rats was established to exceed 2000 mg/kg bw.
