Description of key information

Additional information

The assessment of the environmental fate properties of C18 TMAC is based on data on the substance itself and on the structural analogue quaternary ammonium compounds, C12-C18 (even numbered) alkyltrimethyl chloride (C12-18 TMAC) and benzyl C12-16 (even numbered)-alkyldimethyl chlorides (C12-16 ADBAC). Justification for this read-across approach is provided in a separate document entitled ‘Quaternary Ammonium Salts (QAS): REACH read-across justification for members of the QAS category’ appended to Section 13 of the IUCLID file.
