Applicant's summary and conclusion

Interpretation of results:
readily biodegradable
Executive summary:

In a ready test conducted according to the OECD TG 301C, phthalimide was incubated at an initial test concentration of 100 mg/l. 92 % of the phthalimide were mineralized during 14 days (MITI, 1998).
