Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Data waiving:
study technically not feasible
Justification for data waiving:
Justification for type of information:
Tests in aqueous media with ethyl 2-cyanoacrylate with the intent to determine effective concentrations or no effect concentrations can not be performed due to technical reasons based on the chemical properties of the monomer. In presence of moisture ethyl 2-cyanoacrylate polmerises within seconds (inherent property of ethyl 2-cyanoacrylate based instant glues). Thus, very low determined monomer concentrations in water represent a non ateady state situation from which a defined effective concentration can not be derived. Oral administration would be the most appropriate way. The monomer would polymerized in the oral cavity or when administered by gavage in the stomach. The application in the feed is not possible, as the monomer polymerizes immediately on contact with food. This would allow only the polymer to be tested.
