Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Applicant's summary and conclusion

Conclusions:
Hexamethylene diamine is expected to be distributed mainly in the water compartment (99.2%) and insignificantly in the air compartment (1.95x10-7%).
Executive summary:

Distribution can be modeled with the fugacity model released by EPISUITE v4.00 (EPA). Based on Level III of the fugacity model inputting the key values from the technical dossier, and 1000 kg/h going to water, hexamethylenediamine is expected to be distributed in the environment as 1.95x10-7% in the air compartment, 99.2% in the water compartment, 0.000596% in the soil compartment, and 0.817% in the sediment.
