- Vehicle:
- unchanged (no vehicle)
- 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 test substance 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 test substance was held in contact with the skin with a dressing, consisting of a surgical gauze patch, successively covered with aluminum foil and elastic bandage. A piece of 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:

- No. of animals per sex per dose:
- 5
- Control animals:
- no
- Details on study design:
- Dose volume: 2000 mg/kg (2.53 mL/kg) body weight. Dose volume calculated as dose level (g/kg) / specific gravity (0.79).
DOSAGE PREPARATION: The test substance was dosed undiluted as delivered by the sponsor. No correction was made for purity of the test substance.
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.
- Other examinations performed: none. - Statistics:
- None.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- 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 was, performed according to OECD/EC test guidelines and GLP principles. Five male and five female rats were exposed to 2000 mg/kg bw for 24 hours. No mortality occurred or deviations from normal body weight gain. In the first four days after exposure, clinical signs such as lethargy, hunched posture, piloerection, chromodacryorrhoea, shallow respiration and/or ptosis were noted among all animals. General/maculate/focal erythema, scales and/or scabs were noted on the treated skin area of all animals during the observation period. For one female, hyperthermia of the treated skin area was noted on Day 3.
No macroscopic abnormalities were noted, apart from reddish discoloration of the thymus in one female. Based on these data, the acute dermal toxicity of Oxooil LS13 was found to be greater than 2000 mg/kg bodyweight (Globally Harmonised Classification System - not classified).
