Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Justification for data waiving:
Justification for type of information:
Physical chemical data and data from the toxicological data package may be used to predict the potential ADME characteristics of PMDA. The low toxicity of PMDA in repeat dose studies also lend support to mteabolites of low to no appreciable toxicity.

Applicant's summary and conclusion

The physical chemical characteristics of PMDA and the data from the repeat dose toxicity study clearly suggest and demonstrate that PMDA is likely to be readily absorbed, distributed and excreted with limited bioaccumulation. The data suggest that the liver is a target organ and that enhanced metabolism is likely to occur, although the toxicity of metabolites is likely to be limited as in the genotoxicity studies metabolic activation was without demonstrable effect. Considering these attributes, the most likely route of excretion would be primarily via the urine and secondarily the faeces.
