SKIN REACTIONS: All three rabbits exposed for 4 hours to 0.5 ml, ethylenediamine, propoxylated showed an erythema (grade 1) at the examination time-point 60 minutes after patch removal, rabbit no. 1 until 24 hours and rabbit no. 3 until 48 hours after patch removal.
REVERSIBILITY: All test sites appeared normal at 72 hours. - Other effects:
- None

Applicant's summary and conclusion
- Interpretation of results:
- slightly irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: OECD GHS
- Conclusions:
- Under the present test conditions slight irritation was observed with ethylenediamine, propoxylated. The findings do not warrant classification as skin irritant under GHS.
