Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Sodium isopentyl xanthate as well as other xanthates has low potential for adsorption
It is not expected to bioaccumulate in view of its ionic character nad logKow.

Aquatic bioaccumulation
The following information is taken into account for any hazard / risk / bioaccumulation assessment:
This endpoint is waived in accordance with Column 2 of Annex IX of the REACH Regulation as the substance has low potential for bioaccumulation (f log Kow <= 3) and low potential to cross biological membranes
Terrestrial bioaccumulation
Bioaccumulation of xanthates in most organisms is limited by the metabolism and rapid excretion of carbon disulfide. Bioaccumulation in the food chain is predicted to be low(Office of Pollution and Toxics, U. S. EPA, August 1994, EPA 749-F-94-008a)
The following information is taken into account for any hazard / risk / bioaccumulation assessment:
It is not expected that the xanthates to bio-accumulate in the food chain because of much lower values of BCF and BAF than REACH and US EPA criteria.
