- ANIMAL INFORMATION
Five male and five female Sprague-Dawley CD (Crl: CD®BR) strain rats supplied by Charles River (UK) Ltd., Margate, Kent, were used. At the start of the main study the males weighed 212 to 227 g, and the females 206 to 216 g, and were approximately eight to twelve weeks old. After a minimum acclimatisation period of at 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.
ANIMAL CARE AND HUSBANDRY
The animals were housed in suspended polypropylene cages furnished 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 (Rat and Mouse Expanded Diet No. 1, Special Diets Services Limited, Witham, Essex, UK) was allowed throughout the study.
The animal room was maintained at a temperature of 18 to 22°C and relative humidity of 47 to 61%. On one occasion the temperature was below the limit specified in the protocol (19°C). This deviation was considered not to affect the purpose or integrity of the study. The rate of air exchange was approximately fifteen changes per hour and the lighting was controlled by a time switch to give twelve hours continuous light and twelve hours darkness.
Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- On the day before treatment the back and flanks of each animal were clipped free of hair using veterinary clippers.
A single group of animals was treated as follows:
Dose Level Specific Gravity Dose Volume Number of Rats
(mg/kg) (ml/kg) Male Female
2000 0.958 2.09 5 5
The calculated volume of test material, as received, was applied uniformly 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 bandage was further secured with a piece of BLENDERM wrapped around each end. 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. - Duration of exposure:
- 24 hours
- Doses:
- 2000 mg/kg bodyweight
- No. of animals per sex per dose:
- 5 male and 5 female
- Control animals:
- not required
- 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 distilled water to remove any residual test material. The animals were returned to group housing for the remainder of the study period.
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 p.31. - Statistics:
- No statistical analysis was performed.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute 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. No symbol and risk phrase are required according to EU labelling regulations.
- Executive summary:
Introduction
A study was performed to assess the acute dermal toxicity of the test material in the Sprague-Dawley CD strain rat. The method followed that in the OECD Guidelines for Testing of Chemicals No. 402 "Acute Dermal Toxicity" (adopted 24 February 1987) and Method B3 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).
Method
A group of ten animals (five males and five females) was given a single 24 -hour, semi-occluded dermal application to intact skin at a dose level of 2000 mg/kg bodyweight. The animals were observed for fourteen days after the day of dosing and were then killed for gross pathological examination.
Mortality
There were no deaths.
Clinical signs
No signs of systemic toxicity were noted during the study.
Body weight
All animals showed an expected gain in bodyweight during the study.
Gross pathology
No abnormalities were noted at necropsy.
Conclusion
The acute oral 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. No symbol and risk phrase are required according to EU labelling regulations.
