Description of key information
Dowfax 8390 is not readily biodegradable but inherently biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable, not fulfilling specific criteria
Additional information
The biodegradability of Dowfax 8390 has been evaluated in various biodegradability screening studies. In Soap and Detergent Association-Semi-Continuous Biodegradability Tests, greater than 90% reduction were achieved in methylene blue active substances (i.e., > 90% primary biodegradation). In a Closed Bottle study (OECD 301D) study, 0 -6% biodegradation was observed. Overall, Dowfax 8390 is not readily biodegradable but inherently biodegradable not fulfilling specific criteria.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
