Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Not applicable to solid Sodium isobutyl xanthate which in the presence of moisture and/or heat decomposes to carbon disulphide, alcohol, sodium carbonate and trithiocarbonate.
Carbon disulphide (CAS number 75–15–0) is the major decomposition product and has a low autoignition point and is highly flammable.CS2 has an auto flammability temperature of 99 oC at ambient pressure
Expert Judgement
Due to the decomposition of Sodium isobutyl xanthate when is heated this substance is not considered to exhibit Auto flammability but the major decomposition product Carbon disulphide (CAS number 75–15–0) have to be considered.
Therefore testing for Auto flammability does not need to be performed.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
99 °C
