Applicant's summary and conclusion

Conclusions:
Study technically not feasible: Test not performed because test substance polmerises on contact with water within seconds
Executive summary:

Tests in aqueous media with phenyl-ethyl-cyanoacrylate (PhECA) with the intent to determine readily biodegradability can not be performed due to technical reasons based on the chemical properties of the monomer. In presence of moisture PhECA polymerises within seconds (inherent property of PhECA based instant glues). Thus, very low determined monomer concentrations in water represent a non steady state situation from which a detailed biodegradation property can not be derived.
