Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated information
Conclusions:
Under the test conditions chosen and considering the described findings Asta-C15-acetal does not give indication of an irritatnt property to the skin. Thus, classification is not warranted according to Regulation (EC) No. 1272/2008 and EU Directive 67/548/EEC.
