In accordance with REACH Regulation
1907/2006/EC Annex IX section 188.8.131.52, a study on abiotic degradation is
required as benzyldimethylamine is not ready biodegradable. Based on the
structure of benzyldimethylamine no hydrolysis is expected as no
hydrolysable groups are present. 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). With an adapted sludge the substance
was 100% ready biodegradable (Bayer AG, 1979). In addition,
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 , and at a concentration of 50 µg/L the BCF is < 6.2 to 22.
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).
In accordance with column 2 of REACH Annex
VIII, a Adsoprtions-/Desporptions-Screening test (required in section
9.3.1) does not need to be conducted as benzyldimethylamine has a low
potential for adsorption (log Pow = 1.98). Log Koc values of 2.457 (MCI
method) respectively 1.955 (Kow method) were calculated by KOCWIN v2.00
for completeness sake.
