REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
The hypothesis for this analogue approach is that target and source substances, being different compounds, have similar physico-chemical properties based on structural similarity with common functional groups; a quaternized ethanolamine moiety, one to three ester groups with a typical UVCB distribution with long-chain fatty acids of natural origin.
Furthermore identical precursors (triethanolamine, long-chain fatty acids, dimethyl sulphate) are used for manufacturing. Therefore common breakdown products via physical and biological processes, which result in structurally similar chemicals, are evident.

Key result

Relative self-ignition temperature:

> 402 °C

Remarks on result:

no self ignition observed under the test conditions

Conclusions:

In a study conducted according to EU-Method A.16. Auto-flammability (solids-determination of relative self-ignition temperature) the test substance showed no self-ignition up to a temperature of 402°C at ambient air pressure (1013 hPa).

Description of key information

There is no indication for auto flammability of Fatty acids, C18 unsatd., mono and diester with triethanolamine , di-Me sulfate-quaternized based on read-across information from partially unsaturated TEA-Esterquat.

Additional information

No self-ignition temperature was observed until the maximum temperature of 402°C, according to the testing guideline for auto-flammability (solids-determination of relative self-ignition temperature) in the sense of the consolidated version of Council Directive 67/548/EEC, Annex V, Method A.16 (Council Directive 92/69/EEC).
