- Irritation parameter:
- overall irritation score
- Basis:
- mean
- Time point:
- other: 5 days
- Reversibility:
- not specified
- Remarks on result:
- no indication of irritation
- Irritant / corrosive response data:

Applicant's summary and conclusion
- Interpretation of results:
- other: not irritating
- Conclusions:
- Hairless mice did not show any signs of irritation after repeated exposure to the chemical.
Hence, the test material can be considered as not irritating to skin. - Executive summary:
The skin irritation potential of test chemical was assessed in mice. A 50% dilution in oil (type not specified) of test chemical was applied twice daily for 5 days to 5 hairless mice. The mice were observed for signs of irritation.
Hairless mice did not show any signs of irritation after repeated exposure.
Hence, the test material can be considered as not irritating to skin.
