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.

When water is added to Potassium amyl xanthate it reacts with water to form the others substances: alcohol, potassium carbonate, trithiocarbonate and carbon disulphide.
Carbon disulphide (CAS number 75–15–0) it is the major decomposition product, which is liquid and have to be considered.
The biodegradation of CS2 was >80 % after 28 days of exposure, therefore CS2 is readily biodegradable. Potassium amyl 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 of potassium amyl xanthate.
The biodegradation of 1-pentyl alcohol (Amyl alcohol) was >62 % after 10 days of exposure, therefore 1-pentyl alcohol (Amyl alcohol) is readily biodegradable. Potassium amyl xanthate readily decomposes to Amyl Alcohol, especially in the presence of moisture/water. Amyl Alcohol is both reagents used in the manufacture, as well as decomposition products.
Therefore, the Biodegradation in water of Amyl Alcohol need to be considered in the assessment of potassium amyl xanthate. These results suggest that potassium amyl xanthate will be readily biodegradable and it is not expected to persist in the environment.
These results suggest that potassium ethyl xanthate will be readily biodegradable and it is not expected to persist in the environment.
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.
