Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

According to column 2 of Annex VIII of REACh, a study assessing adsorption/desorption does not need to be conducted as DEIPA and its relevant degradation products decompose rapidly.

Henrys law constant has been estimated using the HENRYWIN (v3.20) program from EPISuite v4.10 (US EPA 2011) to be 5.55E-12 atm-m3/mole (2.27E-010 unitless, 5.62E-007 Pa-m3/mole) and 7.92E-019 atm-m3/mole (3.24E-017 unitless, 8.02E-014 Pa-m3/mole) by the bond contribution and group contribution methods, respectively.

As an approximation (stated within REACh guidance) if Henry's law constant is greater than 100 Pa. m3/mol, more than 50% of the substance could be lost from the water phase in 3-4 hr (ECHA, 2012d).
