- TEST SITE
- Area of exposure: Dorso-lumbar region of each rat
- % coverage: Approximately 10% of the total body surface area
- Type of wrap if used: The treatment area (approximately 50 mm x 50 mm) was covered with porous gauze held in place with a nonirritating dressing, and further covered by a waterproof dressing encircled firmly around the trunk of the animal.
REMOVAL OF TEST SUBSTANCE
- Washing: The treated area of skin was washed with warm water (30 - 40 deg C), to remove any residual test substance. The treated area was blotted dry with absorbent paper.
- Time after start of exposure: 24 hours
TEST MATERIAL
- Amount(s) applied (volume or weight with unit): 3.50 mL/kg bodyweight
- Concentration (if solution): 571 mg/mL
- Constant volume or concentration used: Yes, the amount of test substance necessary to prepare the formulations and the amount actually used were determined on each occasion. The difference between these amounts was checked before the formulations were dispensed.
- For solids, paste formed: Yes
VEHICLE
- Amount(s) applied (volume or weight with unit): 3.50 mL/kg bodyweight
- Concentration (if solution): 1%
- Lot/batch no. (if required): No data
- Purity: No data - Duration of exposure:
- 24 hours
- Doses:
- 2000 mg/kg bodyweight (single concentration)
- No. of animals per sex per dose:
- 5 males and 5 females
- Control animals:
- no
- Details on study design:
- - Duration of observation period following administration: 14 days
- Frequency of observations and weighing: Animals were observed soon after dosing and at frequent intervals for the remainder of Day 1. On subsequent days, animals were observed once in the morning and again at the end of the experimental day (with the exception of Day 15 – morning only). The nature and severity, where appropriate, of the clinical signs and the time were recorded at each observation. The weight of each rat was recorded on Days 1 (prior to dosing), 8 and 15. Individual weekly bodyweight changes and group mean bodyweights were calculated.
- Necropsy of survivors performed: Yes
- Other examinations performed: Cages of rats were checked at least twice daily for any mortalities. Local dermal irritation at the treatment site was assessed daily. All animals were subject to a macroscopic examination which consisted of opening the cranial, thoracic and abdominal cavities. The macroscopic appearance of all examined organs was recorded. - Statistics:
- No data
Results and discussion
Effect levels
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Mortality:
- There were no deaths during the treatment period.
- Clinical signs:
- There were no systemic responses to treatment in any animal.
- Body weight:
- On Day 8, a low bodyweight gain was recorded for two females (An. Nos. K8 and K9) and a bodyweight loss was recorded for one other female (An. No. K7). All other animals were considered to have achieved satisfactory bodyweight gains throughout the study. The low bodyweight gains and loss in some individuals are considered to be within the normal variability limits for female rats and as all animals had good weight gains on Day 15 this was not considered to be of toxicological importance.
- Gross pathology:
- No abnormalities were noted in any animal at the macroscopic examination at study termination on Day 15.
- Other findings:
- - Dermal reactions: Very slight irritation (Grade 1 erythema) was observed in two males following the removal of the dressings on Day 2. These reactions had resolved by Day 6.
- Organ weights: No data
- Histopathology: No data
- Potential target organs: No data
- Other observations: No data

Applicant's summary and conclusion
- Conclusions:
- The acute median lethal dermal dose (LD50) to rats of the test substance was demonstrated to be greater than 2000 mg/kg bodyweight.
The test substance is in Category 3 according to the EPA Health Effects Test Guidelines OPPTS 870.1000 Acute Toxicity testing EPA 712-C-98-189 August 1998. - Executive summary:
