- TEST SITE
One days before the treatment, the backs of the animals were clipped with an electric clipper, exposing an area of approximately 10% of the total body surface. Only animals without injury or irritation on the skin were used in the test.
On test day1, the test item was applied at a dose of 2000 mg/kg body weight evenly on the intact skin with a syringe and covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and fixed with an elastic adhesive bandage.

Body weight was recorded on test day 1 (prior to administration), 8 and 15. Animals were examined for clinical signs daily during the acclimatization period, during the first 30 minutes and at approximately 1, 2, 3 and 5 hours after administration on test day 1. Animals were examined for local signs once daily during days 2-15. All abnormalities were recorded.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The LD50 of GALDEN LMW after single dermal administration to rats of both sexes, observed over a period of 14 days, is greater than 2000 mg/kg body weight.
- Executive summary:
The purpose of this study was to assess the acute dermal toxicity of GALDEN LMW when administered to rats by a single semi-occlusive dermal application, followed by an observation period of 14 days.
Five male and five female HanRcc:WIST (SPF) rats were treated with GALDEN LMW at 2000mg/kg by dermal application. The test item was applied undiluted as delivered from the sponsor at a volume dosage 1.2 mL/kg. The application period was 24 hours. The animals were examined daily during the acclimatization period and mortality, viability and clinical signs were recordered. All animals were examined for clinical signs at approximately 30 minutes, 1, 2, 3 and 5 hours after treatment on day 1 and once daily during test days 2 -15. Local signs were recorded once daily from test day 2 to 15. Mortality/viability was recordered at approximately 30 minutes, 1, 2, 3 and 5 hours after administration on test day 1 (with the clinical signs) and twice daily during days 2 -15. Body weights were recordered on day 1 (prior to administration) and on days 8 and 15. All animals were necropsied and examined macroscopically. No deaths occurred during the study. No clinical signs were observed during the course of the study. The body weights of the animals was within the range commonly recordered for this strain and age. No macroscopic findings were observed at necropsy. In conclusion the median lethal dose of GALDEN LMW after single dermal administration to rats of both sexes, observed over a period of 14 days is LD50 (rat) greater than 2000 mg/kg body weight.
