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

Adsortion/desorption tests results show that TFA is poorly absorbed to the soil and is considered as a mobile organic compound in the majority of soils investigated. The Kd ranged between 0.17 to 20 L/kg for organic and mineral soils (the organic horizon exhibiting greater retention) giving a geometric mean of 0.94 L/kg (SD=4.86, n= 20).

The Henry's Law constant (KH) for trifluoroacetic acid, 0.009 Pa.m3.mol-1, was calculated by the average of two measured values 8950 and 5800 at 25°C reported in two valid peer reviewed studies.With such a value and because trifluoroacetic acid is totally miscible with water and has a log Kow value of 0.79 at 25°C, the preferred environmental compartment will be water, rather than air, ground or biota.
