Is dried super glue toxic if ingested?
Ethyl cyanoacrylate, the main component of super glue, is considered non-toxic in small amounts when used as intended. However, it is not intended to be ingested. Eating dried flakes of the glue may cause minor stomach discomfort, but it is not expected to cause serious harm.
Is super glue food safe after drying?
Remember that super glue is generally not food safe.
