EC number: 931-203-0 | CAS number: -
In a reverse gene mutation assay in bacteria according to OECD guideline 471, 1983, strains TA1535, TA 1537, TA 1538, TA 98 and TA 100 of S. typhimurium were exposed to the fully saturated TEA-Esterquat. Two independent experiments were performed at concentrations of 8, 40, 200, 1000 and 5 000 µg/plate and the second experiment at concentrations of 5, 10, 50, 100, 200 µg/plate in the presence and absence of mammalian metabolic activation.
No evidence of biologically significant mutagenic activity of the test item was found in the presence and absence of metabolic activation, up to and including the limit concentration of 5000 µg/plate. Biologically significant bacteriotoxic effects were observed at concentrations of ≥ 200 µg/plate.
The positive controls induced the appropriate responses in the corresponding strains and activity of metabolizing system was confirmed.
There was no evidence of induced mutant colonies over background.
