Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

There are no studies available investigating the adsorption/desorption behaviour of 2-amino-1,3-propanediol (APD). The Koc was therefore estimated by calculation.


As amine, APD is partly present in its positively charged form under environmental pH. The regression used for calculation takes into account the presence of the charged and uncharged species. The predicted log Koc was 2.31, indicating low adsorption potential.
