Description of key information

Environmental behaviour

1,3-di-o-tolylguanidine (DOTG) is not expected to undergo hydrolysis in the environment. Indeed,the results from the primary hydrolysis tests have demonstrated that the substance is hydrolytically stable at environmental pH.

1,3-di-o-tolylguanidine was not identified as readily biodegradable in a ready biodegradability test.

1,3-di-o-tolylguanidine may sorb on sediment and soil (log Koc = 3.64).


Bioaccumation potential

The partition coefficient of 1,3-di-o-tolylguanidine was assessed in accordance with OECD testing guideline 107 and GLP requirements. The partition coefficient of 1,3-di-o-tolylguanidine was of 2.9 at 25°C.This value also indicates that 1,3-di-o-tolylguanidine is characterised by a low potential for bioaccumulation.
