Description of key information
Additional information
There is no ready biodegradability data available for EPO. A read across approach was conducted with a ready biodegradability study from ESBO (EC No. 232-391-0).
Soybean oil, epoxidised is considered to be readily biodegradable. This was proven in a study conducted by Dr. A.V. Schulthess in 1988 using
OECD guideline 301B.
A ready biodegradability test was conducted on TK 11278(otherwise known as Reoplast 39 or epoxidised soybean oil)using bacteria from a sewage treatment plant. Aniline was used as a reference substance.
After 28 days:
The biodegradation calculated as percentage of measured amount of CO2 over the theory was:
10 mg test substance/L = 79 % in 28 days
20 mg test substance/L = 92 % in 28 days
The % degradation (% ThCO2 formation) exceeded 10% within 2 to 3 days for both concentrations of the test material and subsequently exceeded the 60% pass level within the 10 day window.
Therefore,epoxidised soybeanis readily biodegradable.
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).
