Description of key information
The study provided was conducted to recognised testing guidelines and with GLP certification.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
- Type of water:
- freshwater
Additional information
The biodegradability of the test substance was investigated in a study according to GLP and OECD guideline 301 B. After 28 days a biodegradation rate < 1% was measured (Ciba-Geigy, 1983b).
