Applicant's summary and conclusion

Interpretation of results:
not irritating
Remarks:
Migrated informationCriteria used for interpretation of results: EU
Conclusions:
DTPA-bis(anhydrid) tested as dry powder without being moistened shall not be classified as skin irritating.
Executive summary:

Three rabbits were exposed to the test article at two skin sites on the back. After 4 hours of exposure the test article was removed and the skin examined 1, 24, 48 and 72 hours after termination of exposure.

No skin reactions were observed in any of the animals at any of the observations.

under the experimental conditions described in this report, the mean score for erythema was 0.0 and for oedema 0.0 .

DTPA-bis(anhydrid) tested as dry powder without being moistened shall not be classified as skin irritating.
