Description of key information

The autoflammability of members of category C4, high 1,3 -butadiene (>0.1%). range is 364 to 413°C

Key value for chemical safety assessment

Additional information

 Autoflammability data was available from proprietary studies from BASF for the CAS numbers 87741 -01 -3, 92045 -23 -3 and 64742 -83 -2 (BASF 2008). The studies were based on standard guidelines and so were considered reliable for use. The autoflammability of Category C4, high 1,3 -butadiene (>0.1%)is therefore reported to range from 364 to 413°C.
