Test animals
- Species:
- rat
- Strain:
- Wistar
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- Five male and five female Wistar (RccHan™:WIST) strain rats were supplied by Envigo RMS (UK) Limited, Oxon, UK. On receipt the animals were randomly allocated to cages. The females were nulliparous and non-pregnant. After an acclimatization period of at least 5 days the animals were selected at random and given a number unique within the study by indelible ink-marking on the tail and a number written on a cage card. At the start of the study the animals weighed at least 200 g, and were 8 to 12 weeks of age. The weight variation did not exceed ±20% of the mean weight for each sex.
The temperature and relative humidity were set to achieve limits of 19 to 25°C and 30 to 70% respectively. The rate of air exchange was at least fifteen changes per hour and the lighting was controlled by a time switch to give 12 hours continuous light and 12 hours darkness.
Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- The calculated volume of test item, as received, was applied as evenly as possible to an area of shorn skin (approximately 10% of the total body surface area) using a graduated syringe. A piece of surgical gauze was placed over the treatment area and semi-occluded with a piece of self-adhesive bandage. The animals were caged individually throughout the study. Shortly after dosing the dressings were examined to ensure that they were securely in place.
- Duration of exposure:
- 24 hours
- Doses:
- 2000 mg/kg bw
- No. of animals per sex per dose:
- 4
- Control animals:
- no
- Details on study design:
- After the 24-Hour contact period the bandage was carefully removed and the treated skin and surrounding hair wiped with cotton wool moistened with dimethyl sulphoxide followed by distilled water to remove any residual test item. As no mortalities were noted a further group of animals (four males and four females) was similarly treated with the test item at a dose level of 2000 mg/kg body weight to give a total of five males and five females. The animals were caged individually for the 24-Hour exposure period. After the 24-Hour contact period the bandages were carefully removed and the treated skin and surrounding hair wiped with cotton wool moistened with dimethyl sulphoxide followed by distilled water to remove any residual test item. These animals were returned to group housing for the remainder of the test period.
The animals were observed for deaths or overt signs of toxicity 30 minutes, 1,2 and 4 hours after dosing and subsequently once daily for 14 days.
After removal of the dressings and subsequently once daily for 14 days, the test sites were examined for evidence of primary irritation and scored.
At the end of the study the animals were killed by cervical dislocation. All animals were subjected to gross necropsy. This consisted of an external examination and opening of the abdominal and thoracic cavities. The appearance of any macroscopic abnormalities was recorded. No tissues were retained. - Statistics:

- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute dermal median lethal dose (LD50) of the test item in the Wistar strain rat was found to be greater than 2000 mg/kg body weight. The test item does not meet the criteria for classification according to the Globally Harmonized System of Classification and Labelling of Chemicals.
- Executive summary:
Introduction
The study was performed to assess the acute dermal toxicity of the test item in the Wistar strain rat.
Methods
Initially, two animals (one male and one female) were given a single, 24 hour, semi-occluded dermal application of the undiluted test item to intact skin at a dose level of 2000 mg/kg body weight. Based on the results of the initial test, a further group of eight animals (four males
and four females) was similarly treated. Clinical signs and body weight development were monitored during the study. All animals were subjected to gross necropsy.
Results
Mortality. There were no deaths.
Clinical Observations. There were no signs of systemic toxicity.
Dermal Irritation. There were no signs of dermal irritation.
Body Weight. All animals showed expected gains in body weight.
Necropsy. No abnormalities were noted at necropsy.
Conclusion
The acute dermal median lethal dose (LD50) of the test item in the Wistar strain rat was found to be greater than 2000 mg/kg body weight. The test item does not meet the criteria for classification according to the Globally Harmonized System of Classification and Labelling of Chemicals.
