Description of key information

In accordance with column 2 of REACH Annex VII, testing of TEA-Esterquats for oxidising properties does not need to be conducted, as the substances do not contain any structural groups known to be correlated with a tendency to react exothermally with combustible material. In addition, the thermodynamic calculations and the negative oxygen balance for partially unsaturated TEA-Esterquat indicate that the substance may rather be assessed as combustible than to have oxidising properties. 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 oxidising properties. This is laid down in the supporting study.

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 tendency to react exothermally with combustible material. In addition, the thermodynamic calculations and the negative oxygen balance for partially unsaturated TEA-Esterquat indicate that the substance may rather be assessed as combustible than to have oxidising properties. In conclusion, structural aspects and estimated thermodynamic properties indicate that oleic acid-based TEA-Esterquat must not be considered to have oxidising properties.
