Executive summary:

A study was conducted to determine the flash point ofthe test substance 'didecyldimethylammonium chloride' (DDAC), using a closed crucible according to DIN ISO 2719, EU Method A.9 (Flash-Point). The test substance was been determined to have a flash point of 26.4°C at 103.6 kPa.

Description of key information

The flash point of the liquid form of the test substance was determined using a closed crucible according to DIN ISO Method 2719 and EU Method A.9 (Keipert, 2002).

Key value for chemical safety assessment

Flash point at 101 325 Pa:
26.4 °C

Additional information

 The liquid form of the test substance was determined to have a flash point of 26.4°C at 103.6 kPa, indicating a flammability potential for the typical marketed form of the test substance.
