Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Justification for type of information:
Due to the decomposition of Reaction mass of SEX 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.

Description of key information

Not applicable to solid Reaction mass of SEX 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 Reaction mass of SEX 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
