Description of key information

According to column 2 of REACH Annex VII, testing of explosive properties does not need to be conducted. TEA-Esterquats do not contain any structural groups known to be correlated with a particular explosion hazard. In addition, the thermodynamic calculations for partially unsaturated TEA-Esterquat indicate that the heat of decomposition and the comparison with the heat of combustion does not necessitate explosivity to be expected. Finally, the overall oxygen balance is negative. In conclusion, structural aspects and estimated thermodynamic properties indicate that fully saturated and oleic acid based TEA-Esterquats, which are structurally very close to partially unsaturated TEA-Esterquat, and therefore must not be considered to have explosive properties.

Additional information

Justification for classification or non-classification

Oleic acid-based TEA-Esterquat does not contain any structural groups known to be correlated with a particular explosion hazard. In addition, the thermodynamic calculations indicate that the heat of decomposition and the comparison with the heat of combustion does not necessitate explosivity to be expected. Finally, the overall oxygen balance is negative. In conclusion, structural aspects and estimated thermodynamic properties indicate that oleic acid-based TEA-Esterquat must not be considered to have explosive properties.
