Description of key information
Since the pass value of > 60 % was not reached within 28 days. 4,6-dichloro-N-(1,1,3,3-tetramethylbutyl)-1,3,5-triazin-2-amine cannot be considered to be readily biodegradable according to OECD guideline 301 B.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
- Type of water:
- other: ultrapure grade water
Additional information
The ready biodegradability of4,6-dichloro-N-(1,1,3,3-tetramethylbutyl)-1,3,5-triazin-2-aminewas assessed by measurement of CO2evolution based on the OECD Guideline 301 B.4,6-dichloro-N-(1,1,3,3-tetramethylbutyl)-1,3,5-triazin-2-aminewas tested at a nominal concentration of 15 mg carbon/L calculated at mg/L.
The following biodegradation was determined at the end of the 28-d period:
*4,6-dichloro-N-(1,1,3,3-tetramethylbutyl)-1,3,5-triazin-2-amine 24 %
*Sodium benzoate 76 %
Since the pass value of > 60 % was not reached within 28 days 4,6-dichloro-N-(1,1,3,3-tetramethylbutyl)-1,3,5-triazin-2-aminecannot be considered to be readily biodegradable according to OECD guideline 301 B.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
