Applicant's summary and conclusion

Interpretation of results:
readily biodegradable
Conclusions:
On the basis of results obtained, interpreted in accordance to OECD 301:1992, OECD Section 3 Part 1: 2006 the test item "GLYCERY 1,2-DIACETATE 3-(9,10-) EPOXYOCTADECANATE” should be considered biodegradable in aerobic condition.
