Irritant / corrosive response data:
Skin was discribed as bleached in 2/6 animal 24 h post application.
Skin was discribed as dry in 3/6 animal 72 h post application.
1/6 animals had a fisur 72 h post aplication.
Except edema after 72 h (score 2.7) results on abraded skin were in the same range as those on non-abraded skin.

Applicant's summary and conclusion

Interpretation of results:
irritating
Remarks:
Migrated information
Executive summary:

The study is reliable with restrictions due to some deviations to the OECD Guideline. The test substance was applied on abraded and non-abraded skin of 6 rabbits. Edema (max.3 of 4 ) and Erythem (max. 4 of 4) was observed. Primary dermal irritation index was 3.2.

The study was terminated 72 h post application and effects were not fully reversible within this time.

Conclusion

1,4 -bis[(vinyloxy)methyl]cyclohexane is irritating to the skin.
