Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Expert Judgement
Potassium isobutyl xanthate readily decomposes to carbon disulphide, especially in the presence of moisture/water. Therefore, the Biodegradation in water of carbon disulphide (CS2) need to be considered in the assessment ofpotassium isobutyl xanthate.
Due to their structural similarity, it is expected that all xanthates would have similar Biodegradation effects either due to the xanthate or carbon disulphide.
On this basis, testing for Biodegradation in water for Potassium isobutyl xanthate is not applicable
Carbon disulphide (CAS number 75–15–0) it is the major decomposition product, which is liquid and have to be considered.
According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE”, a simulation testing on ultimate degradation in surface water, the study does not need to be performed if the substance is ready biodegradable. As Potassium isobutyl xanthate is ready biodegradable a ready biodegradability study does not need to be conducted.
Therefore testing for Biodegradation in water does not need to be performed.

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).
