Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Adsorption/desorption:
Key study: estimated by calculation: Koc = 2.738. It is concluded that sodium trichloroacetate showed a low soil sorption, so it is concluded that sodium trichloroacetateshowed a low soil sorption, in particular to the predominately negatively charged soil colloids, because of its physicochemical properties (high water solubility, strong dissociation in aqueous solution).
Henry's Law constant:
Key study: estimated by calculation (EPI Suite v3.20, EPA). The estimated Henry's Law constant for sodium trichloroacetate is 24x10-9atm.m3/mole at 25 ºC.
Distribution modelling:
Percent distribution in media: Air: 0.422%; Water: 50.1%; Soil: 49.4%; Sediment: 0.0973% Persistence time: 1110 h = 46 d. Half lifes; Air: 100,000 h = 4167 d =11 a; Water: 1440 h = 60 d; Soil: 2880 h = 120 d; Sediment: 13,000 h = 542 d; Volatilization from water; Half life vom Model river: 33,220 h = 1384 d; from Model Lake: 362,500 h = 15,104 d = 41 years.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
