- TEST ANIMALS
- Source: Charles River (UK) Ltd., Margate, Kent
- Age at study initiation: approximatively 12 Weeks
- Weight at study initiation: Males 233 to 257 g, Females 205 to 227 g
- After a minimum acclimatisation period of 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.
- Housing: 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.
- Diet (e.g. ad libitum): Teklad Rat-Mouse Rodent Diet. ad libitum
- Water (e.g. ad libitum):ad libitum
- Environement: animal room was maintained at a temperature of 19 to 25 C and relative humidity of 50 to 60%. The rate of air exchange was approximately 15 changes per hour and the lighting was controlled by a time switch to give 12 hours continuous light and 12 hours darkness.
ENVIRONMENTAL CONDITIONS
- Temperature (°C): 22+/-3 °C
- Humidity (%): >30 %
- Air changes (per hr): 10 - 15
- Photoperiod (hrs dark / hrs light): 12 hours continuous light/dark cycle

- Area of exposure: back and flanks
- % coverage: ca. 10%
- Type of wrap if used: A piece of surgical gauze was placed over the treatment area and semi-occluded with a piece of self-adhesive bandage
(HYPERTIE). The bandage was further secured with a piece of BLENDERM wrapped around each end.
REMOVAL OF TEST SUBSTANCE
- Washing (if done): After the 24-hour contact period the bandage was carefully removed and the treated skin and surrounding hair wiped with cotton wool moistened with arachis oil B.P. to remove any residual test material
- Time after start of exposure: 24 h
- Duration of exposure:
- 24 h
- Doses:
- Single dose level of 2000 mg/kg bodywight
- No. of animals per sex per dose:
- 5m, 5f, dosed at 2000 mg/kg bw
- Control animals:
- not required
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Animals were observed for deaths or overt signs of toxicity ½, 1, 2 and 4 hours after dosing and subsequently once daily for 14 days. Individual bodyweights were recorded prior to application of the test material on Day 0 and on Days 7 and 14.
- Necropsy of survivors performed: Yes
- Other examinations performed: gross pathological examination, behaviour or clinical signs, body weight, dermal reaction - Statistics:
- No statistical analysis was performed.

- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- No intercurrent deaths occured during the course of the study.
- Clinical signs:
- No signs of systemic toxicity were noted during the study.
- Body weight:
- All animals showed expected bodyweight gain during the study.
- Gross pathology:
- No abnormalities were noted at necropsy.
- Other findings:
- Very slight or well-defined erythema was noted at the treatment sites of the female animals on removal of the patches and persisted for 3 or 4 days after treatment. Crust formation was evident at one treatment site 3 and 4 days after treatment. All treatment sites appeared normal 5 days after treatment.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute, dermal toxicity of the test material was assessed in accordance with OECD Guideline 402. The median lethal dose of the test material after single dermal application to rats of both sexes, is greater than 2000 mg/kg body weight. As such, the test material does not meet the GHS criteria for classification.
- Executive summary:
Guideline
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 described in the OECD Guidelines for Testing of Chemicals No. 402 "Acute Dermal Toxicity" (adopted 24 February 1987) and Method 83 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC). The method also complies with the requirement of US Environmental Protection Agency (EPA) Toxic Substances Control Act (TSCA) and Australian Toxicology Guidelines.
Method
A group of ten animals (five males and five females) was given a single 24-hour, semioccluded 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 treatment and were then
killed for gross pathological examination.
Results
There were no deaths. No signs of systemic toxicity were noted during the study. Signs of irritation noted in the female animals were very slight to well-defined erythema with crust formation evident at one treatment site.
All animals showed expected bodyweight gain during the study.
No abnormalities were noted at necropsy.
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.
