Additional information

In the frame of laboratory studies, DTDMAC was demonstrated to be non bioaccumulative with whole body BCF of 32 (well water) and 13 (river water). The ecological effects of the substance are strongly dependent on the test medium, differences are caused by adsorption onto suspended matter and complexation with anionics. Therefore, the relevant ecotoxicity values are derived from tests in river water. Therefore DTDMAC is considered to be non bioaccumulative and the same conclusion applies to N-benzyl-N-C16-18 (even numbered) -alkyl-N-methyl-C16-18 (even numbered) -alkyl-1-aminium chloride.
