Specific details on test material used for the study:
- Name of test material (as cited in study report): Trimethyloctadecyl ammonium chloride (C18 trimethyl QAS)
- Composition of test material, percentage of components: Stearyltrimethyl ammonium chloride : 99.2% (w/w) (C-chain distribution: C16: 0.8% (w/w) and C18: 99.2%(w/w))
- Impurities: Stearyldimethyl ammonium hydrochloride: 0.2% (w/w); stearyldimethyl amine: 0.3% (w/w); sodium chloride: <0.1%(w/w)

Key result
Test procedure:
burning rate test over 100 mm length
Burning time:
>= 94 - <= 159 s
Remarks on result:
other: burning times over 100 mm were never less than 45 seconds upon testing 6 times

The screening test resulted in a burning rate shorter than 4 minutes for 200 mm. Therefore the full burning rate test was performed. The sample burns, melts and flows out over the base plate. Burning times over 100 mm are shown in the table below:

 Burning times over 100 mm of test substance were never less than 45 seconds. Therefore the test substance was not considered as highly flammable.

Conclusions:
Under the test conditions, the test substance was considered as not highly flammable.
Executive summary:

A study was conducted to determine the flammability of the test substance according to EU Method A.10. A preliminary and a full study were performed. The screening test resulted in a burning rate shorter than 4 minutes for 200 mm. Therefore the full burning rate test was performed 6 times. Burning times over 100 mm of test substance were never less than 45 seconds. Under the test conditions, the test substance was considered as not highly flammable (Kamp, 2012).

Description of key information

The flammability was determined according to EU Method A.10 (Kamp, 2012)

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Justification for classification or non-classification

C18 TMAC was non flammable in a guideline test, thus no classification is required for flammability according to Directive 67/548/EEC and Regulation (EC) 1272/2008.
