- One group of 5 male and 5 female rats. Upon arrival, all animals were housed individually in clean, wire-mesh cages. The animals were maintained by the animal husbandry staff of Charles River in accordance with SOPs. Animals were maintained in accordance with the Guide for the Care and Use of Laboratory Animals.2 The animal facilities at Charles River Ashland are accredited by AAALAC International. Enrichment devices were provided to all animals as appropriate throughout the study for environmental enrichment and to aid in maintaining the animals’ oral health, and were sanitized weekly.

Results and discussion
Effect levels
- Key result
- Sex:
- female
- Dose descriptor:
- LD50
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Remarks on result:
- no indication of skin irritation up to the relevant limit dose level
- Mortality:
- No mortality.
- Clinical signs:
- other: No significant clinical observations.
- Gross pathology:
- At the scheduled necropsy, macroscopic findings consisted of blue discolouration of the tail for 4 males and all females. Blue discolouration was observed at the application site for 1 female. The discolouration findings were expected based on the colour of test material and were not considered adverse.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Based on the results of this study, the LD50 of the test material was greater than 2000 mg/kg when administered once for 24 hours to the clipped, unabraded skin of male and female albino rats.
- Executive summary:
Based on the results of this study using OECD 402, the LD50 of the test material was greater than 2000 mg/kg when administered once for 24 hours to the clipped, unabraded skin of male and female albino rats.
