Description of key information

6-phenyl-1,3,5-triazine-2,4-diyldiamine is not readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
under test conditions no biodegradation observed

Additional information

Practically no biodegradation observed under test conditions by the result from OECD TG 301C and 301E.

 Test result Data   OECD TG   Source
Under test conditions no ready biodegradation observed in water  BOD 2% (at BG 100mg/L) after 28 day  301C  Katagiri
 Not regarded readily biodegradable in water  DOC 14% (at BG 17.1 mg/L) after 28 day 0% (at BG 34.2 mg/L) after 28 day  301E  Muttzal

Estimations performed by using the software BIOWIN (v.4.10) support the observations of the two guideline studies. In addition, the simulations give indication on ultimate biodegradation of Benzoguanamine within a timeframe of weeks to months.
