Applicant's summary and conclusion

Interpretation of results:
Category 1B (corrosive) based on GHS criteria
Conclusions:
Skin corrosive (Category 1B) was observed.
Executive summary:

In a primary skin irritation/corrosion study, two rabbits were exposed to N,N'-bis(3 -aminopropyl)piperazine for 3 min and four rabbits were exposed for 1h. Observations were made 1 h, 24 h, 48 h and 8 d after exposure. While only mild irritation was observed after 3 min exposure, skin corrosion was observed after 1 h of exposure.

Based on these results:

- according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations, N,N'-bis(3 -aminopropyl)piperazine should be classified as: Skin corrosive (Category 1B).
