- TEST SITE
- Area of exposure: the back of each animal (4 cm x 5 cm area, 10% of body surface) was clipped free of hair with electric clippers to allow administration of the test material.
- Type of wrap if used: The test material was evenly applied to the shorn back of each animal and was kept in contact with the skin for approximately 24 hours using a semiocclusive dressing wrapped around the trunk. Each dressing consisted of a gauze patch to cover the treated area and was held in place by a adhesive bandage.
REMOVAL OF TEST SUBSTANCE
- Washing: The skin at the site of application was cleansed of any residual test material with lukewarm water
- Time after start of exposure: At the end of the 24 hour contact period.
TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 5.0 g test material in 10.0 mL of distilled water. 0.4 mL was applied per 100 g bodyweight. The amount of test material applied was calculated for each animal according to its weight at the time of dosing. - Duration of exposure:
- 24 hours
- Doses:
- 0 (vehicle control), 2000 mg/kg bw
- No. of animals per sex per dose:
- 5
- Control animals:
- yes, concurrent vehicle
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: All animals were checked twice daily for mortality, morning and afternoon. Clinical observations were recorded individually within the first hour after dosing, then daily for the duration of the observation period. The application site was examined daily for signs of dermal irritation. Bodyweights were recorded immediately before dose administration and then on day 7 and day 14.
- Necropsy of survivors performed: All animals were killed by CO2 asphyxiation and subjected to a necropsy examination.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of the test, the acute dermal median lethal dose of the test material was estimated to be in excess of 2000 mg/kg in male and female rats. The study is considered to be reliable, relevant and adequate for risk assessment and classification and labelling purposes.
- Executive summary:
The acute dermal toxicity of the test material was determined in accordance with standardised guidelines OECD 402, EU Method B.3 and EPA OPP 81 -2. During the study, five male and female rats received a single dermal application of 2000 mg/kg of the test material and were assessed daily for the following 14 days for any signs of systemic toxicity. None of the animals died and there were no signs of systemic toxicity. All animals gained weight during the study. There were no macroscopic abnormalities at examination post mortem. The acute dermal median lethal dose of the test material was estimated to be in excess of 2000 mg/kg to both male and female rats.
