- Sprague-Dawley
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- Five male and five female Sprague-Dawley CD (Crl: CD® (SD) IGS BR) strain rats were used. On receipt the animals were randomly allocated to cages. The females were nulliparous and non-pregnant. After an acclimatisation period of at least five 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 200g and were eight to twelve weeks of age.The animals were housed in suspended solid-floor polypropylene cages finished with woodflakes. The animals were housed individually during the 24-hour exposure period and in groups of five, by sex, for the remainder of the study. Free access to mains drinking water and food was allowed throughout the study. The diet, drinking water and bedding were routinely analysed and were considered not to contain any contaminants that could reasonably be expected to affect the purpose or integrity of the study.The temperature and relative humidity were set to achieve limits of 19 to 25°C and 30 to 70% respectively. Any occasional deviations from these targets were considered not to have affected the purpose or integrity of the study. The rate of air exchange was at least fifteen changes per hour and the lighting was controlled by a time switch to give twelve hours continuous light (06:00 to 18:00) and twelve hours darkness.The animals were provided with environmental enrichment items which were considered not to contain any contaminant of a level that might have affected the purpose or integrity of the study.
Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- other: Moistened with distilled water
- Duration of exposure:
- 24h
- Doses:
- Single dose of 2000 mg/kg bodyweight
- No. of animals per sex per dose:
- Five males dosed at 2000 mg/kg bodyweightFive females dosed at 2000 mg/kg bodyweight
- Control animals:
- no
- Details on study design:
- On the day before treatment the back and flanks of each animal were clipped free of hair.A group of five male and five female rats was treated with the test material at a dose level of 2000 mg/kg. The appropriate amount of test material, moistened with distilled water, was applied as evenly as possible to an area of shorn skin (approximately 10% of the total body surface area). 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 for the 24-hour exposure period. Shortly after dosing the dressings were examined to ensure that they were securely in place.After the 24-hour contact period the bandage was carefully removed and the treated skin and surrounding hair wiped with cotton wool moistened with distilled water to remove any residual test material. The animals were returned to group housing for the remainder of the study period.The animals were observed for deaths or overt signs of toxicity 0.5, 1, 2 and 4 hours after dosing and subsequently once daily for fourteen days.After removal of the dressings and subsequently once daily for fourteen days, the test sites were examined for evidence of primary irritation and scored according to the following scale from Draize J H (1977) "Dermal and Eye Toxicity Tests" In: Principles and Procedures for Evaluating the Toxicity of Household Substances, National Academy of Sciences, Washington DC page 31.
Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Mortality:
- There were no deaths during the study.
- Clinical signs:
- other: No clinical signs or signs of systemic toxicity were observed.
- Gross pathology:
- No abnormalities were noted at necropsy.
- Other findings:
- Signs of toxicity (local):Blue coloured staining was observed at all treated skin sites for up to five days. This did not affect the evaluation of the skin reactions.Very slight erythema was noted at all treated skin sites one and two days after treatment, at two treated skin sites three days after treatment and persisted at one treated skin site four and five days after treatment.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute dermal median lethal dose (LD50) of the test material in the Sprague-Dawley CD strain rat was found to be greater than 2000 mg/kg bodyweight.
- Executive summary:
Introduction
The study was performed to assess the acute dermal toxicity of the test material in the Sprague-Dawley CD strain rat. The method was designed to meet the requirements of the following: OECD Guidelines for the Testing of Chemicals No. 402 "Acute Dermal Toxicity" (adopted 24 February 1987) • Commission Directive 92/69/EEC Method B3 Acute Toxicity (Dermal)
Method
A group of ten animals (five males and five females) was given a single, 24-hour, semi-occluded dermal application of test material to intact skin at a dose level of 2000 mg/kg bodyweight. Clinical signs and bodyweight development were monitored during the study. All animals were subjected to gross necropsy.
Results
There were no deaths or signs of systemic toxicity during the study. Very slight erythema was noted at all treated skin sites one and two days after treatment, at two treated skin sites three days after treatment and persisted at one treated skin site four and five days after treatment. All animals showed expected gains in bodyweight over the study period. No abnormalities were noted at necropsy.
Conclusion
The acute dermal median lethal dose (LDso) of the test material m the Sprague-Dawley CD strain rat was found to be greater than 2000 mg/kg bodyweight.
