Description of key information
Ready Biodegradability of bis(2,3-epoxypropyl) terephthalate in a Manometric Respirometry Test
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The test item bis(2,3-epoxypropyl) terephthalate contains no nitrogen, therefore the evaluation of biodegradation has to be based on the ThODNH4. The criterion for ready biodegradability under the conditions of a manometric respirometry test is the 10-day window, describing the period between reaching at least 10% degradation and 60% degradation. This period should not exceed 10 days.
The mean biodegradation after 28 days of bis(2,3-epoxypropyl) terephthalate was 83% (ThODNH4); the 10 day window criterion was passed from day 2 until day 12.
Therefore, bis(2,3-epoxypropyl) terephthalate is considered to be readily biodegradable.
