Description of key information

Additional information

There are no experimental data available for TEA-Esterquats from bioaccumulation studies. There are, however, measured data available for a structurally similar compound (DODMAC).

The aquatic BCFs for a similar substance (DODMAC) are 12 l/kg and 13 l/kg . The calculated BCF for the all TEA-Esterquat species is 71 (BCFWIN v2.17).

For DODMAC, the measured sediment accumulation factors for two worm species are 0.28 - 0.78, and the biota-to-soil accumulation factor for 4 different terrestrial plants is in the range of 0.005 - 0.025.

The registration substances, TEA-Esterquats, are readily biodegradable and are subject to degradation by hydrolysis. In organisms, the substances are de-esterified and further degraded via the fatty-acid metabolic pathway. Aquatic bioaccumulation and the terrestrial bioaccumulation are expected to be of the same order of magnitude as that of DODMAC. The bioaccumulation potential of the registration substances is expected to be low.
