Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Additional information

No measured data on photodegradation/photolysis are available for TEA-Esterquats. However, 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 days (pH 9) were deduced from the reaction rate constants at 25 °C. Di- and mono-esters were detected as degradation products.
