According to the Regulation EC No 2022/477 (REACH) Annex VIII 22.214.171.124 column 2, the hydrolysis study is not carried out, since it is not expected that the substance hydrolyze under environmental conditions based on chemical structure. The substance contains no organic functional groups that may hydrolyze under environmental condition like alkyl halides, amides, amines, carbamates, exposides, esters of almost all organic acids and nitriles. The test substance consists only of organic functional groups that are relatively or completely inert with respect of hydrolysis. Based on the chemical structure an estimation of the hydrolysis rate is not possible.The substance can thus be regarded as hydrolytically stable. This is further supported by its application and use in aqueous solution. In addition, a calculation with EPIWIN v4.00 also predicts no hydrolysable groups.
Benzyldimethylamine was shown to be not ready biodegradable in different ready biodegradability tests using non-adapted sludge (MITI, 1992). Benzyldimethylamine was shown to be 100% inherently biodegradable after 13 days and fulfilled the criterion for inherent, ultimative biodegradability (BASF, 1987).
Benzyldimethylamine determined to be non or not highly bioaccumulative. The BCF at a concentration of 500 µg/L is 2.1 to 6.4 L/kg , and at a concentration of 50 µg/L the BCF is < 6.2 to 22 L/kg. The study was conducted according to "Bioaccumulation test of chemical cubstance in fish and shellfish", order of the prime minister, the minister of health and welfare, the minister of international trade and industry No 1, Japan, 1974 (MITI-Online, MITI-Buch, 1992).
The QSAR determination revealed a logarithmic organic carbon-water partition coefficient of 2.46 of the test substance, and Koc value of 286.7 L/kg (KOCWIN 2.01). As the adsorption coefficient (Koc) of N,N-Dimethylbenzylamine is 286.7 (Blue Frog Scientific, 2023), the result indicates that the substance is of medium mobility in soils according to McCall et al. (1981).
