Cyanoacrylates bond skin and eyes in seconds. Studies have shown that methyl-2-cyanoacrylate (SuperGlue and KrazyGlue) degrade fairly rapidly upon contact with living tissue. This leads to the release of formaldehyde and a toxic response. 2-octyl cyanoacrylate degrades much slower due to its longer organic backbone which slows the degradation of the adhesive enough to remain below the threshold of tissue toxicity. Due to these toxicity issues, 2-octyl-cyanoacrylate is used for sutures.
