Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Photodegradation in air

No measured data on photodegradation/photolysis are available for TEA-Esterquats. Due to the very low emissions of TEA-Esterquats to air (negligible vapour pressure) the extent of photodegradation in air has no relevance for the environmental fate for this class of chemicals.



TEA-Esterquats are characterized by hydrophobic parts of the moieties “R” linked to the charged head group via ester bonds R-C(O)O-and are therefore expected to be subject to degradation by chemical or biological hydrolysis. This is supported by the test on hydrolysis for partially unsaturated TEA-Esterquat. Half-lives of 17 (pH 7) and 11.3 d (pH 9) were deduced from the reaction rate constants at 25 °C. Di- and mono-ester were detected as degradation products.

According to REACH regulation (Annex VIII, column 2) a hydrolysis test does not need to be conducted if the substance is readily biodegradable. As the TEA-Esterquats are determined to be readily biodegradable, biodegradable under anaerobic conditions and under different environmental conditions (water, sewage treatment plants) a study on hydrolysis is considered to be not necessary.
