Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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 soybean is readily biodegradable.
