Does Band-Aid Liquid Adhesive Bandage contain cyanoacrylate?

Yes, it does. Here's a quote from Johnson & Johnson, the manufacturers. Based on a proprietary 2-octyl cyanoacrylate technology which allows a device to contain a monomer at room temperature that can polymerize rapidly upon activation and form a tenacious bond, Dermabond™ quickly found acceptance in emergency rooms and clinics all over the country. Dermabond adhesive polymerizes on contact with moisture on the skin's surface to form a strong but flexible film that allows the patient to go about routine daily activities, even showering. The consumer version of Dermabond™ is BAND-AID® Brand Liquid Bandage. In their own Word's, "Discover the ultimate liquid bandage: it stays on better than ordinary bandages, even on those hard-to-cover places. Liquid Bandage has a no-sting formula that dries quickly and forms a clear, flexible, breathable seal that is 100% waterproof. It stops minor bleeding and minor pain instantly, while keeping out water, dirt, and germs".
