Liquid bandage is a topical skin treatment for minor wounds which binds to the skin to form a protective polymeric layer that keeps dirt and germs out and moisture in.[1]
For the fast-acting, reactive adhesive that is used to mend deep cuts or surgery wounds, see cyanoacrylates (specifically 2-Octyl cyanoacrylate).

Design
Liquid bandage is typically a polymer dissolved in a solvent (commonly water or an alcohol), sometimes with an added antiseptic and local anesthetic, although the alcohol in some brands may serve the same purpose.[1] These products protect the wound by forming a thin film of polymer when the carrier evaporates.[1] Polymers used may include polyvinylpyrrolidone (water based), ethyl cellulose, pyroxylin/nitrocellulose or poly(methylacrylate-isobutene-monoisopropylmaleate) (alcohol based), and acrylate or siloxane polymers (hexamethyldisiloxane or isooctane solvent based).[1]
In addition to their use in replacing conventional bandages in minor cuts and scrapes, they have found use in surgical and veterinary offices.[1] Liquid bandages are increasingly finding use in the field of combat, where they can be used to rapidly stanch a wound until proper medical attention can be obtained.[1]
Recent developments
A novel type of liquid bandage would incorporate amino acids to form peptide links directly with the skin.[2] This product has potential to reduce bleeding during and after surgery.
