Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE, study for Stability and reactivity is only required if stability of the substance is considered to be critical.
Expert Judgement
SIBX is stable under normal ambient and anticipated storage and handling conditions of temperature and pressure. SIBX powder and pellets are stable if stored under dry, cool conditions. Incompatible with oxidising agents (eg. hypochlorites) and acids (eg. nitric acid).
However, it is hygroscopic and when exposed to moisture in air it decomposes, releasing carbon disulphide.
SIBX is stable on storage and does not react with its container under normal conditions of use and storage.
Therefore testing for Stability: thermal, sunlight, metals does not need to be performed.

Justification for classification or non-classification
Based on the hazard assessment of Sodium isobutyl xanthate in section 2.1 and 2.2 in IUCLID 6, available data for the substance and according to the criteria described in Directive 67/548/EEC and in the Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP Regulation):
Directive 67/548 |
Thermal stability R5 Heating may cause an explosion. R6 Explosive with or without contact with air.
|
CLP |
Self-reactive substances and mixures H240: Heating may cause an explosion. H241: Heating may cause a fire or explosion. H242: Heating may cause a fire. Self-react. Type A Self-react. Type B Self-react. Type C Self-react. Type D Self-react. Type E Self-react. Type F Self-react. Type G

It is concluded that none of the above phrase has not to be assigned to Sodium isobutyl xanthate and does not meet the criteria to be classified for Stability: thermal, sunlight, metals.
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).
