Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information Criteria used for interpretation of results: other: Regulation EC 1272/2008 (CLP)
Conclusions:
Under the conditions of the study, the test item 1,5,9 -cyclododecatrien showed no irritant effects on eyes and mucosa of male and female rabbits which leads to no classification according to 67/548/EEC and according CLP regulation (1272/2008).
Executive summary:

To test the acute irritant effect on eyes and mucosa the test item 1,5,9 -cyclododecatriene was administered undiluted into eyes or eyelid sacs of 3 male and 3 female rabbits (OECD 405 guideline study). According to the study, the test item 1,5,9 -cyclododecatriene showed no irritant effect ont he eyes and mucisa of male and female rabbits.
