ENVIRONMENTAL CONDITIONS
- Temperature (°C): 19 to 23°C
- Humidity (%): 40 to 70%
- Air changes: The animal room was kept at positive pressure with respect to the outside by its own supply of filtered fresh air, which was passed to atmosphere and not re-circulated.
- Photoperiod (hrs dark / hrs light): 12 hours continuous light and 12 hours continuous dark per 24 hours.

- Area of exposure: treatment area was approximately 50 mm x 50 mm
- % coverage: 10% of the total body surface area
- Type of wrap if used: porous gauze held in place with a non-irritating dressing, and further covered by a waterproof dressing
REMOVAL OF TEST SUBSTANCE
- Washing (if done): the treated area of skin was washed with a mild detergent solution and then rinsed with warm water (30 - 40°C), to remove any residual test substance
- Time after start of exposure: At the end of the 24 hours exposure
TEST MATERIAL

- 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 weight of each rat was recorded on Days 1 (prior to dosing), 8 and 15.
- Other examinations performed: clinical signs, body weight, dermal reactions, histopathology
Results and discussion
Effect levels
- Key result
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- There were no deaths and no treatment related clinical signs were observed.
- Clinical signs:
- There were no deaths and no treatment related clinical signs were observed.
- Body weight:
- Low bodyweight gains were recorded for two females on Day 8 and three
females on Day 15.
All remaining animals were considered to have achieved satisfactory bodyweight gains
throughout the study. - Gross pathology:
- No abnormalities were noted in any animal at the macroscopic examination at study
termination on Day 15.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The acute median lethal dermal dose (LD50) to rats of Bis(C9 (branched)alkyl) benzene-1,4-
dicarboxylate was demonstrated to be greater than 2000 mg/kg bodyweight.
