Biodegradation in water: screening tests
Administrative data
- Endpoint:
- biodegradation in water: ready biodegradability
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- other:
- Justification for type of information:
- Tests in aqueous or moist media with allyl 2-cyanoacrylate cannot be performed due to technical reasons based on the chemical properties of the monomer. In presence of moisture allyl 2-cyanoacrylate polymerises within seconds (inherent property ofallyl 2-cyanoacrylate based instant glues). The substance allyl 2-cyanoacrylate is a representative of the group of cyanoacrylate based reactive glues. Colloquially this type of glues is named ‘instant glues’ indicating that they cure within seconds to minutes. The polymerisation reaction starts with the reaction of traces of hydroxide ions with the activated double bond and leads to insoluble polymers within very short periods of time. The concentration of hydroxide ions originating from the autoprotolysis of ambient moisture or adsorbed water on surfaces (COH- = 10-7 mol/L) is sufficient to start the polymerisation reaction. For details on the reaction of cyanoacrylates in presence of moisture and polymerisation reaction rates see chapter 5.6 Additional information on environmental fate and behaviour.
