Applicant's summary and conclusion

Interpretation of results:
irritating
Remarks:
Migrated information Criteria used for interpretation of results: EU
Conclusions:
The registered substance is considered to be skin irritating.
Executive summary:

The skin irritating potential of tripropenyl succinic anhydride was investigated according to test guidline OECD 404. Very slight to well-defined erythema and very slightly to moderate edema were seen on during the observation period. All the effects were fully reversible. The average values of erythema and edema scores at time points of 12, 48 and 72 h after treatment are 1.6 and 1.1, respectively. In addition, Skin dry, brittle and scaly were observed after 14d. Based on these findings, the registered substance is considered to be skin irritating.
