Applicant's summary and conclusion

Interpretation of results:
other: not classified according to the CLP Regulation (EC) No. 1272/2008
Conclusions:
The test item was found to be not irritating to rabbit skin.
Executive summary:

The test item was investigated for skin irritating property in rabbits using a guideline given by the U.S. Department of Agriculture (Fed. Reg 38, 187, 27019, 1973). A single dose was tested on the skin of six rabbits. The test item was applied to intact and wound skin of each animal. The degree of irritation/corrosion was read and scored for oedema and erythema reactions at intervals of 24 and 72 hours.

The test item caused no irritation in the skin of rabbits.
