Constituent 1
Test animals
- Species:
- rat
- Strain:
- Wistar
- Sex:
- male/female
- Details on test animals or test system and environmental conditions:
- The rats were supplied by Harlan Laboratories UK Limited. On receipt the animals were randomly allocated to cages.
Acclimatisation period: At least 5 days. Animals were selected randomly and given a number unique within the study by indelible ink-marking on the tail and identified by a number written on a cage card.
Age at the beginning of the study: 8-12 weeks. Bodyweights: +- 20% of the mean weight of any previously dosed animals.
With the exception of an overnight fast immediately before dosing and for approximately three to four hours after dosing, free access to mains drinking water and food (2014 Teklad Global Rodent diet supplied by Harlan Teklad, Blackthorn, Bicester, Oxon, UK) was allowed throughout the study.
Temperature and relative humidity: 19-25°C and 30-70% respectively.
Rate of air exchange: At least 15 changes per hours.
Lighting: 12h continuous light & 12h darkness.
Administration / exposure
- Type of coverage:
- semiocclusive
- Vehicle:
- water
- Duration of exposure:
- 24 hours
- Doses:
- 2000 mg/kg bodyweights
- No. of animals per sex per dose:
- 5 males and 5 females
- Control animals:
- no
- Details on study design:
- 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-h exposure period. Shortly after dosing the dressings were examined to ensure that they were securely in place.
After the 24-hours 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.
Animals were observed for deaths or overt signs of toxicity 1/2, 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 according to the scale from Draize J H (1977) "Dermal and Eye Toxicity Tests". Any skin reactions, if present were also recorded.
Individual bodyweights were recorded prior to application.

Applicant's summary and conclusion
- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The acute dermal median dose of the test material in the Wistar strain rat was found to be greater than 2000 mg/kg bodyweight.
- Executive summary:
The study was performed to assess the acute dermal toxicity of the test material following a semi occluded dermal application of the test material to intact skin of the Wistar strain rat. 5 males and 5 females were dosed at 2000 mg/kg bw. No deaths occurred and no abnormalities were noted. LD50 was found to be greater than 2000 mg/kg bodyweight.
